Which Small-Engine Oil Would You Choose?

Which Small-Engine Oil Would You Choose?

Spring marks the time to store your snowblower and prepare your lawnmower, pressure washer, generator and other equipment for another season.

Make sure to change oil before storing equipment. Used oil contains acidic byproducts that can damage the engine if allowed to sit for months.

If you neglected to change oil in your lawnmower or other equipment prior to fall storage, now is a great time to do that.

Use a high-quality small-engine oil, not simply an inexpensive automotive oil

While easy to assume small equals simple when it comes to engines, the opposite is often true.

Compared to liquid-cooled automotive engines, air-cooled small engines run hotter; operate under constant load; generate more contaminants (with many not using a filter); and are exposed to mud, dirt and rain. Plus, they’re often overlooked when it comes to maintenance.

Most small-engine oils, however, are just re-labeled automotive oils, which are formulated with fuel economy in mind, not engine durability.

AMSOIL Synthetic Small-Engine Oil, in contrast, isn’t merely a re-labeled automotive oil – it’s designed specifically for the unique demands of small engines. It contains a heavy dose of zinc anti-wear additives to protect against wear for maximum power and engine life. It also contains potent detergency additives to fight harmful deposits.

Look at the bottom image of the valve-guide area in a Honda* 5-hp engine tested in the AMSOIL mechanical lab. A competitor’s oil resulted in heavy deposits that caused the valve to stick. In fact, the technician who tore down the engine couldn’t remove the valve due to excessive deposits. Had this engine been in the field, it would have been a matter of time before it failed, leading to a costly repair or replacement. AMSOIL 10W-30 Synthetic Small-Engine Oil, in contrast, minimized deposits and kept the engine running strong.

Small Engine 10W-40 is another product.

This season, make sure your fleet of small-engine-powered equipment is protected – choose AMSOIL.

“Easier starts in cold weather and the ultimate in protection at any temperature. Zero wear on my small engines and most are over 10 yrs old.”

Stiction… What Is It?

Stiction… What Is It?

Mark Nyholm|

By now you’ve inevitably seen this term in turbo diesel enthusiast magazines.  And if you own a Ford Powerstroke 6.0L diesel engine, then you likely have experienced it. Stiction… it’s a combination of two words. Static and Friction. What it really means is that there are two components touching each other and a specific force is required to get them to move relative to each other. Like your pen resting on your desk. It requires a certain amount of force to get your pen to slide across your desk.

Solving Stiction on Ford 6.0Stiction has been a marketing term in the turbo diesel market for about the past 6-8 years now with the issues that Ford has seen with their 6.0L diesel engine. It’s a HEUI motor that, unfortunately, Ford made a poor decision to crank up the fuel pressure while utilizing similar injectors to the 7.3L diesel and they just aren’t capable of handling the pressure. So what happens is the solenoid on the injector that controls when the injector fires wears and gets sloppy. That wear puts it into a binding condition and the injector control is lost. The net result is poor idle and throttle response.

So what have some savvy entrepreneurs done? They’ve come out with a product to improve on the situation. Unfortunately the problem is irreversible. You cannot replace wear with chemistry. So can it make it better for the short term? Yes. However it is truly short term and typically ends in injector replacement.

What is the magic chemistry in a small bottle that costs so much? It is a combination of detergent and friction modifier. The detergent goes in there and cleans up any deposits in the oil side of the injector to ensure the solenoid can fire as smooth as possible. The friction modifier goes in there and coats the two metallic components and provides a more slippery surface so that the increased clearance between the two of them results in less binding. Unfortunately this method doesn’t last that long and you have to either keep adding this special juice or just replace the injectors.

I’m sure if you are a 6.0L owner you are wondering what I could have done differently. Unfortunately, based on the design and pressures, I’m doubting whether there is a foolproof method to eliminate the problem. But there are ways to lessen the pain and improve on the longevity of those injectors.

First, you want to choose a high quality synthetic diesel engine oil, like AMSOIL, to ensure your injectors are staying clean and the oil is providing the best wear protection possible. Regular oil change intervals using a high quality oil filter is step two to this important process. And finally if you are trying to keep the oil side of the injector clean you better think about the nozzle of the injector and keeping that fuel flowing as Ford intended. Using a concentrated dose of diesel fuel additive, like AMSOIL Diesel Injector Clean, will help keep that injector flowing like new.

One more thing for northern climate enthusiasts to consider is engine oil viscosity. Since the HEUI injector uses engine oil to build fuel pressure it is very important to ensure the viscosity of the oil is suitable to promote development of proper fuel pressure. Take a look into your owner’s manual the next time you are in the garage. Your book will tell you that a 5W-40 or 15W-40 oil is recommended in most conditions, however if the temperature drops into the freezing range, Ford recommends you change to a 10W-30. No mystery why that is. The lower viscosity of the 10W-30 will flow more freely in cold temps and help develop fuel pressure much easier. Something to consider as you plan your oil changes throughout the year. Perhaps a viscosity change in the fall is the right answer for you. Whatever you choose to do, be confident that AMSOIL has a full line of high performance turbo diesel products for your truck.

Z-ROD® Keeps Classic Vehicles Street-Ready

Vintage Car and Cam Wear Problems Solved – Zinc Fortified Motor Oils

After this long Sioux Falls winter, making the transition from storage to the street can be an anxious time for classic car owners. Even after extensive preparations, doubts may linger whether a prized vehicle has been effectively protected during a period of inactivity. Many owners now look to modern technology to keep vintage hot rods and muscle cars performing at a high level on the street and fully protected during storage.

Protecting engines designed decades ago- and engines modified for increased performance- can be challenging. From flat-tappet cams and splash-lubricated components to the toll of periodic storage, unique issues must be addressed.

Amsoil Z-Rod high Zinc oil

Flat-Tappet Cams and ZDDP

The design of flat-tappet cams makes them especially vulnerable to wear. As the name indicates, the tappet- or lifter – is flat. During operation the surface of the cam lobe slides rapidly over the surface of the tappet, producing high friction and temperatures. The camshaft and lifters are responsible for triggering the precisely tuned movements of the valve train. Here, the use of anti-wear additives becomes crucial.

Stop Cam Wear – No Aftermarket Oil Additives Needed

Zinc dialkyldithiophosphate (ZDDP) is a commonly used motor oil additive that provides anti-wear protection and minimizes lubricant breakdown. ZDDP also exhibits mild extreme-pressure protection. As temperatures in an engine rise, ZDDP decomposes, and the resulting chemistry protects critical metal surfaces.

Without the protective film barrier provided by ZDDP, the cams and lifters wear from the force of operation, negatively affecting cam and valve operation. Because most V-8 engines of the muscle car era came standard with flat-tappet cams, the problem is prevalent to classic-car and hot rod owners.

In these applications, modern oils, such as AMSOIL synthetic motor oils, are capable of providing adequate wear protection after the engine has been broken in. But due to variables like severity of service and level of modification, AMSOIL primarily recommends high-ZDDP oils in these applications, such as Z-ROD® Synthetic Motor Oil. When breaking in a rebuilt or high-performance engine, AMSOIL recommends AMSOIL Break-In Oil, which contains high levels of ZDDP for added protection.

Rust and Corrosion

Moisture can be as devastating an engine contaminant as dirt or sludge. Vehicles subjected to long-term storage are especially vulnerable to humidity-driven rust and corrosion. AMSOIL Z-ROD® Synthetic Motor Oil is formulated with a unique blend of rust and corrosion inhibitors to ensure maximum protection during storage.

AMSOIL Z-ROD® Synthetic Motor Oil (ZRT, ZRF)

  • 10W-30 and 20W-50
  • Protects flat-tappet cams
  • Long-term rust and corrosion protection

AMSOIL Break-In Oil (BRK) SAE 30

  • Quickly seats rings
  • Protects vital parts from wear
  • Increased film strength

AMSOIL Z-Rod 10W-30 ZDDP now in Corvair

Written by Ches Cain

I just drained out the break-in oil for the “High Zinc” or ZDDP fortified synthetic by AMSOIL. This product is under the name of Z-ROD. (10W-30)

Impressions will be recorded but the car is on jack stands getting the rear suspension updated and the floor is being rust proofed.

We have a lot of other processes going on so the Corvair updates may take time. I am working on several websites, expanding our business and serving our daily walk in customers.

I am planning the Corvair to be the car which gets the most miles!! Wait till you see the suspension mods.

Anyway I just switched out the Clarks factory style oil filter with their oil filter adapter so we can use the AMSOIL Nanofiber oil filters. These are the best oil filter money can buy. Why? Because they are “absolute” at 20 microns, use a glass fiber which used no resins which will flow throughout its lifespan at all temperatures. The capacity is at least three times of any other filter its size due to the small fibers and controlled filter areas.
Here are a couple photos of the unit with our filters. (I’m using the old EAO-57 from a stock load of years ago – this filter is replaced by the EAO-51 now).

The bypass kit will follow soon!! I have not decided if I will go with the single or dual. I have made a 2nd spin on oil filter adapter with a port to feed a single should I wish to go that route. Oil analysis will be recorded!

Future mods to the engine will be fuel injection!
