Winter is on the horizon and it’s time to store your lawnmower and other lawn and garden equipment through the colder months. The following tips will help you maximize the life and performance of your lawnmower and ensure it springs quickly to life when you’re ready to mow grass again.

Stabilize the gas

Without a stabilizer gasoline can break down in as few as 30 days. Oxygen, humidity, heat and other factors cause gas to change over time. Varnish, gums and other debris may form, which can clog the tiny passages in fuel lines and injectors or stick the floats in carburetors, preventing the engine from starting in the spring.

AMSOIL Gasoline Stabilizer disrupts the chemical chain reaction that causes gas to oxidize and form varnish and gums. It keeps fuel fresh up to 12 months. As shown, it also fights corrosion and improves stability better than Sea Foam Motor Treatment*.

Clean or replace the spark plugs

The spark plugs in a well-maintained lawnmower should last for years. Even so, check the condition for excessive deposits or wear to the electrodes. Clean on a wire brush (bench grinder is what I use) or replace any dirty plugs as needed. While you’re at it, check the gaps and set them to the proper size, as indicated in the owner’s manual.

Fog Spray the engine

With the spark plug removed, spray fogging oil into the engine. It protects the cylinder, piston and valves from rust and dry-start-induced damage in the spring. Slowly pull the starter cord a few times to distribute the oil, then replace the plug.

Remove the battery

You know, people don’t maintain batteries like they used to.. To prevent frigid temperatures from freezing and ruining the battery, remove it and store it in a safe, climate-controlled environment. Avoid placing it next to your furnace, water heater or other mechanicals in the basement. Put it on a shelf away from open flames. Clean any deposits on the terminals.

Clean and protect the mower deck

Use compressed air, a putty knife, water and AMSOIL Heavy Duty Degreaser to remove grass clippings, leaves, dirt and other caked-on debris from the engine and mower deck. Don’t forget to clean the underside of the deck, too.

Let me tell you something, If you prefer to ease the pain of doing this dirty work again next year, try coating the underside of the mower with AMSOIL Mudslinger. It forms a durable armor against the accumulation of grass clippings, making cleanup easier.

Change the oil and filter

Too many people let the mower go another year without changing the oil.. Don’t do that! Used oil contains acids that can slowly rust or corrode metal components. Once rust or corrosion start, they don’t stop. Contaminants can flake off and populate the oil. When the engine is running, they scour like sandpaper and wear out metal parts. Prior to storage, change the oil to remove acidic byproducts and ensure maximum protection against rust and corrosion throughout the winter.

Clean or change the air filter

A steady supply of clean air is just as important to engine operation and performance as high-quality fuel. Grass clippings, leaves, dirt and other contaminants can clog the air filter, causing the engine to start hard or run poorly.

Direct compressed air from the inside of the filter toward its outside to remove contaminants prior to storage. If it’s excessively dirty, replacing it is cheap insurance. The air filter is the only line of defense keeping contaminants from entering the intake and wearing out the cylinder and piston rings. It’s far less expensive to replace an air filter than an engine. Heck I always vacuum mine and it lasts for years. I used to buy them cheap at Kmart. Wish we still had our Kmart around..

Sharpen the blades

This isn’t required before lawnmower storage, but it’s more convenient to do it now, so nothing prevents a quick mow when that first sunny and dry spring day finally arrives. Remove the blades and sharpen them using an angle or bench grinder, but don’t hesitate to replace them if they’re in bad shape. I’ll tell you what, look for a good mower shop (dont tell him you use AMSOIL as he’ll know you never need repairs, lol) and see if they do blade sharpening. Proper sharpening in a jig makes a huge difference especially in a mulching mower.

Store in a dry, covered place

Once the mower is cleaned and prepared for storage, place it in a clean, dry place for the winter. Avoid storing it outside, but if you have no choice, secure a tarp over mechanical equipment to help protect sensitive components from the elements.

Following these simple lawnmower storage and maintenance tips will ensure your mower starts right up in the spring and continues to provide excellent service for many years.

We also have some advice for when your lawnmower won’t start, and if you prefer videos, we’ve got that too:

Save Every Drop of Horsepower with UPPER CYLINDER LUBRICANT

Written by Charleen

AMSOIL UPPER CYLINDER LUBRICANT:  I use it and it works!

Now on the market for about a year: AMSOIL Upper Cylinder Lubricant (UCL) is the latest addition to the gasoline additive lineup. It delivers more lubricity than the competition and battles ethanol-related corrosion.

Fuel Additive Product Overview

Upper cylinders are one of the toughest areas of an engine to lubricate due to the intense heat of combustion and the design of today’s vehicles. New AMSOIL Upper Cylinder Lubricant delivers a much-needed layer of protection to this trouble area to help fight piston-ring and cylinder wear, maximizing engine compression and horsepower. Its lubricity improvers aid in protecting fuel injectors and other fuel-system components from wear, helping ensure excellent performance and long life.

Plus, it really works. AMSOIL Upper Cylinder Lubricant delivers 18 percent more lubricity than Lucas* and 20 percent more than Sea Foam* for better retention of horsepower and fuel economy. ¹

Inhibits Corrosion

Upper Cylinder Lubricant uses potent corrosion inhibitors to coat metal surfaces, block out moisture and stop deterioration before it starts. This is particularly important when using gasoline that contains ethanol due to its propensity to attract water and hasten corrosion. Inhibiting corrosion maximizes component life and reduces wear in the engine’s top-end to guard against compression loss and maintain optimum power.

Keeps Injectors Clean

Upper Cylinder Lubricant contains detergent additives designed to maintain injector cleanliness. It’s designed to work in concert with AMSOIL P.i. Performance Improver (API) to maintain injector and combustion-chamber cleanliness, retain fuel-economy and performance gains and maximize component life.

Capless-Compatible Packaging

The AMSOIL Upper Cylinder Lubricant bottle is fully compatible with capless fuel systems. Many new vehicles have replaced traditional fuel caps with capless systems. The threads on most bottles restrict them from opening the flap inside the fuel neck and also make removing the bottle difficult. Our packaging makes it easy to insert, pour and remove the bottle.

 

¹ Based on independent testing of AMSOIL Upper Cylinder Lubricant, Lucas Upper Cylinder Lubricant and Sea Foam Motor Treatment obtained on 02/13/2019 using the ASTM D6079 modified for use with gasoline.

User Comments:

I’ve been using this for almost a year now.  In my Ford Focus which is the 2.0 non-turbo I can now use 10% ethanol and get over 40 MPG! I drive from Sioux Falls to Omaha and back often so I can see a difference. It seems the only logical reason this happens is the better lubricity in the head and cylinder ring area. There must be a good amount of friction there. And the parts of the lubricant perhaps seal the rings and valves better as well as the valve stem.

As soon as I get 1000 miles on my Corvair (new engine and heads) I’ll try this as there is even greater friction on horizontal cylinders. It seems to sort of work like lead once did.

If you are going on a long trip keep this in the tank for maximum efficiency. The upper cylinder areas need lubrication. Adding this to the fuel relieves more stress from the engine thus better long term efficiency.

The best way to buy is by the case reducing the price low enough to only cost pennies per tank of gasoline.  Thus we keep several cases in stock for your use.

A closer Look At Engine Sludge

Written by Charleen

Preventing Causes of Engine Oil SLUDGE

Brands matter, quality matters and frequent oil changes will not alter this. It’s all based on the additive quality and it does effect the price.

Engine sludge occurs when oxidized oil and contaminants build up on engine surfaces. It can restrict the flow of oil to the point of engine failure and costly repairs.

As the oil installed in your vehicle ages, oxygen reacts with the lubricant, resulting in a permanent chemical change. The oil picks up oxygen and becomes thicker. Just like oxygen attacks metal surfaces and causes corrosion, it negatively affects lubricants and reduces their ability to lubricate, cool and protect components. Excessive heat speeds the oxidation process. In fact, every 18°F (10°C) increase in temperature doubles the rate of oxidation.

Adding to the challenge, contaminants begin to form during normal operation. In engines, hot combustion gases can blow by the piston rings and contaminate engine oil. Glycol from engine coolant, water that forms with temperature fluctuations and fuel are other common contaminants that affect lubricants. Left unchecked, contaminants accelerate chemical reactions, which overload the lubricant and cause the formation of sludge – a gelatinous substance that wreaks havoc in engines.

Sludge can block the oil passages and oil-pump pick-up screen, resulting in oil starvation. Often, the negative effects are cumulative rather than sudden. Many engines with variable valve timing (VVT) use oil pressure-operated mechanical devices to change valve timing, duration and lift. Sludge can plug the solenoid screen or oil gallies and impact the operation of VVT mechanisms, eventually leading to a costly repair bill. Sludge reduces efficiency and increases time and money spent on maintenance.

Signature Series vs. Sludge

Signature Series Synthetic Motor Oil was subjected to the Sequence VG test to measure its ability to prevent sludge. As expected, Signature Series produced an oil pick-up tube screen virtually free from sludge (see image below). Our unique combination of detergents and high-quality base oils control oxidation and sludge to keep engines clean and efficient.

AMSOIL synthetic lubricants not only resist oxidation and sludge formation, they can help clean existing deposits in neglected engines due to superior detergency. With modern engines and equipment demanding higher-quality lubricants, it’s good to know AMSOIL synthetic lubricants are formulated to protect against sludge in the toughest operating conditions.

Sludge: a gelatinous substance that wreaks havoc in engines.

 

 

 

 

Signature Series has 50 percent more
detergents¹ to help keep oil passages clean and promote oil circulation. It provides 90% better protection against sludge².

 

 

Synthetic Warehouse note:

We own an ecoboost engine (on our Ford van) so based on our personal experience the Signature Series is the only choice in these engines. They run extremely hot effecting the process mentioned above. Test the oil you are using now at or near Ford’s maximum interval and I’m certain it’s beyond it’s life!! TBN and Oxidation levels can be at dangerous levels.  Signature Series gives you that extra benefit of the doubt because when the detergents dissipate you can start to have severe wear from corrosion and of course needless deposits from sludge AND increased oil consumption. We eliminated 75% of a resent F150 Ecoboost V6 oil consumption problem using the Engine Flush (FLSH) and the Signature Series 5W-30 (ASL).

It’s not just about keeping your car or truck longer. It’s the issues our competition causes such as carbon coating your intake valves which is an issue on modern gasoline direct injection engines.  It’s very costly to clean these as there is no-longer the gasoline we enjoyed as the cleaning agent. Fuel is shot directly into the quench area so oil vapors land on valves and build up over time.
Some newer cars do have an additional injector in the throttle body for start-up and cleaning but this will not be the common setup.

So AMSOIL Signature series will keep these areas cleaner as that’s part of what you are paying for. AMSOIL’s lowest volatility is by far worth paying for. And in some cases you pay less for our product than several of the “so called synthetics”.

Make our Sioux Falls locations your only source for lubricants! Many have made the switch for good. We’re at 47073 98th St just behind Marlins Diner. Exit 73 on I29. Or call to make sure I’m there at 605-274-2580.

Small engine won’t start? Identifying the Cause.

Written by Charleen

Small engine won’t start?

Bad gas is the number-one reason, and here’s how to prevent it.

Len Groom | TECHNICAL PRODUCT MANAGER, POWERSPORTS

In northern Minnesota, where I live, the temperature occasionally breaks 80ºF (27ºC) in the summer. When it does, it’s time to fire up my Jet-Skis* and hit the lake. The last thing I want to do on a sunny summer day is mess around with equipment that refuses to start or run properly.

Bad gasoline is the number-one reason seasonal equipment starts hard or runs rough. Over time, gasoline changes, leaving behind gums, varnish and other solids that foul the fuel system and prevent gas from flowing into the combustion chamber. In severe cases, gasoline can change so dramatically that it no longer ignites.

Gasoline is predominantly a mixture of carbon and hydrogen atoms bonded together into energy-dense hydrocarbons. Like conventional base oils, it’s derived from crude oil via a distillation process that uses heat, pressure and other catalysts to create different fractions. Gasoline is comprised of hydrocarbons that are lighter than those found in, for example, diesel fuel or conventional base oils. Refiners add ethanol to the formulation, typically 10 percent, but as high as 85 percent.

Time Takes Its Toll – You Must Treat Gasoline

Time, however, takes its toll on gasoline. Exposure to heat, humidity, atmospheric pressure, oxygen and other variables degrade fuel.

In addition to gums and varnish becoming more concentrated and less soluble as lighter hydrocarbons evaporate, gas is continually oxidizing, which further contributes to varnish and other gunk. Gasoline oxidizes more quickly than motor oil and its negative effects are more immediately noticeable. That’s why it’s important to use high quality gas and store it in approved containers where air infiltration is limited, like inside a ventilated garage or shed, and not in the back of your truck or under the deck.

Meanwhile, ethanol added to gasoline at the refinery can absorb water from the atmosphere, which can lead to phase separation, which occurs when ethanol and gas separate, much like oil and water. Ethanol that has absorbed enough moisture and has sat long enough can foul the fuel system and prevent the engine from starting.

AMSOIL Fights Corrosion

AMSOIL provides corrosion protection Sea Foam® Motor Treatment can’t match, helping maintain power and performance and keeping metal looking like new even when subjected to salt water.  ?

? Based upon independent testing of AMSOIL Gasoline
Stabilizer obtained Nov. 8, 2018 and Sea Foam Motor
Treatment purchased Oct. 25, 2018 in a modified NACE
TM0172 using synthetic sea water per ASTM D665 part B.

This all sounds dire, but it’s nothing treating your gasoline with AMSOIL Gasoline Stabilizer (AST) can’t solve. Gasoline Stabilizer keeps fuel fresh up to 12 months. AMSOIL Quickshot® (AQS) stabilizes gasoline during short-term storage up to six months, in addition to providing potent cleaning benefits and protection against ethanol issues.

What does stabilizer do?

That explanation may suit some people, but this is Tech Talk, so let’s look at the chemistry behind gasoline stabilizers.

You’ve probably heard terms like “free radicals” and “antioxidants” in relation to your health. A free radical is an unpaired electron, and most are unstable and highly reactive. They can either donate an electron to, or accept an electron from, other molecules. This starts a chain reaction that can lead to oxidative stress and cell damage. Left unchecked, free radicals can lead to health problems, like cardiovascular disease and cancer. To help fight free radicals, we should eat plenty of foods rich in antioxidants, which lessen their effects. Antioxidants can “donate” an electron to free radicals or trap them, effectively reducing their instability without becoming unstable themselves. Antioxidants aren’t silver bullets, but they go a long way toward improving our health.

By analogy, gasoline stabilizer is an antioxidant for your gasoline. It disrupts the free-radical-induced chain reaction that causes gas to oxidize and form varnish and gums. Some stabilizer products, like Quickshot, also contain chemistry that increases solvency and breaks down existing varnish, helping clean a dirty carburetor and restore performance. As shown, Gasoline Stabilizer also fights corrosion better than Sea Foam Motor Treatment.

Neglecting to stabilize your gas can lead to all sorts of headaches when it’s time to remove your lawnmower, generator, string trimmer or Jet-Ski from storage. For best results, stabilize your gasoline all year long. That’ll ensure your equipment is ready to roll when you are.
