Reposting this past article on our Signature Dexos R 0W-40 and 5W-50. They’re huge sellers in our Omaha location but want to get the word out about the supply here in Sioux Falls.

GM recently launched a new motor oil performance standard with its proprietary dexos R motor oil specification. Dexos R denotes 0W-40 and 5W-50 motor oils that can withstand the rigors of high-speed and high-load conditions created during high-performance driving. As of now, the specification only applies to high-performance engines used in Corvettes and Camaros.

Modern engines with high power density, forced induction, multi-point fuel injection, cylinder deactivation and emissions systems are driving demand for more advanced lubricants. High-performance vehicles push those technologies to another level, requiring a motor oil that can protect components operating in extreme heat and high-load conditions.

Testing is complete and AMSOIL Signature Series already outperforms the dexos R specification. The dexos R icon will be added to Signature Series 0W-40 and 5W-50 packages.

The GM dexos R motor oil specification applies to modern high-performance Corvettes and Camaros.

AMSOIL has pushed lubricant technology to new levels since 1972 when AMSOIL 10W-40 Synthetic Motor Oil became the first synthetic motor oil in the world to meet American Petroleum Institute service requirements. Since then, we have never stopped pushing ourselves to develop more-advanced formulations. The result? We continue to produce the best motor oils on the market.

Stop in and try the 5W-50 “Corvette” oil and discover the performance improvement! Or really the one oil which lets the engine operate to it’s potential!

AMSOIL Hybrid Motor Oil Protects Hybrid Engines

AMSOIL Hybrid Motor Oil Addresses Hybrid Engine Challenges

_by Johnny Gage |Dec 7th, 2023

Your Maintenance Choices should match the Motives of Hybrid Engine ownership

Hybrid vehicles are designed to improve fuel efficiency and reduce emissions. They combine an internal combustion engine powered by traditional fuels with an electric motor powered by batteries. The electric motor is used to propel the vehicle from stops and for low-speed driving and the gasoline engine takes over powering the vehicle at higher speed and recharges the batteries.  

Hybrids are projected to be 18% of cars on the road by 2035 and roughly half of all hybrid owners identify themselves as automotive enthusiasts. These are drivers searching for modern technology and premium products, who are also committed to maintaining their own vehicles, maximizing safety and reliability, and saving money. 

Hybrid engine challenges – You mean they didn’t do any long term studies??

So often new engine technology requires specific lubricant needs but the call to the manufacturers for a new specification usually lags the issues after issues are discovered.

Hybrid vehicles endure a unique set of challenges due to frequent starting and stopping of the engine. Intermittent operation of combustion engines makes them especially vulnerable to corrosion.

The Key Issue: The infrequent use and instant load  before the engine has had time to warm up creates a situation where the engine cannot evaporate condensation inside the block. This causes rust, greater wear and reduces efficiency. Cooler cylinders can also cause incomplete combustion, increasing the likelihood of unburnt fuel leaking into the crankcase and contaminating the motor oil. It happens all the time and can be mitigated! 

Often the lubricant requirements for these vehicles unique situations are beyond what is available off the shelf at your auto parts store. Not to mention that lower standard of oil you get with the “A Year of Free Oil Changes” or vats at the quicklube.  Not so with AMSOIL!!

Additionally, motor oil needs to flow quickly to critical components every time the engine engages, which is problematic when the engine is constantly cold due to being idle. Hybrid engines are also required to engage quickly under high-load operation to assist the electric motor and must be able to rapidly reach increased engine speeds.

Hybrid engines require high-quality oil that resists moisture, flows properly before it reaches operating temperatures and resists oxidation once it heats up.  

Hybrid solution

AMSOIL 100% Synthetic Hybrid Motor Oil is specifically engineered to address the unique demands of hybrid electric (HEV) and plug-in hybrid electric (PHEV) engines, with a boosted dose of dispersants and inhibitors to help prevent condensation-related corrosion and maintain optimal engine performance. Its robust viscosity combats the negative effects of fuel dilution and maintains consistent and optimal flow of oil to key engine components at low temperatures, ensuring rapid protection at startup.

AMSOIL Synthetic European Motor Oil includes FS, MS and LS identification to help differentiate between full-SAPS, mid-SAPS and low-SAPS formulations. What does that mean? European vehicles feature gasoline and diesel engines with emissions systems that are highly sensitive to SAPS (sulfated ash, phosphorus and sulfur) content. SAPS are common oil additives that provide desirable performance properties, including detergency and protection against wear and oxidation. However, protecting sensitive emissions systems found in European vehicles requires different SAPS levels for different vehicles – it’s not a one-size-fits-all deal.

The New SEVERE GEAR Easy-Pack

The New SEVERE GEAR Easy-Pack

Enthusiasts pride themselves on finding their own solutions to tough problems. When there’s no manual, they roll up their sleeves and make it work. But even the most inventive gearhead inevitably throws down an oily rag and wonders why the process has to be so difficult. Changing gear lube is often one of those frustrating tasks.

Differentials Require Service

A clean, high-quality gear lube helps prevent the howls and whines that can occur from extended periods of metal-to-metal contact. It provides differentials and transmissions with crucial protection – particularly against the rigors of towing and hauling – and it should be changed on a schedule to protect your pickup. Unfortunately, changing this vital fluid doesn’t come without challenges.

Tight Squeeze

Removing the cover on your “pumpkin” and draining the fluid might not be difficult, but installing new fluid requires the ability to push liquid uphill. Unless the pickup is lifted, differentials are packed in high and tight. Reaching fill holes is difficult, and you cannot tip the bottles at an angle that allows the fluid to run into the differential with the help of gravity.

Troublesome Current Solutions

That’s why most gear lube is sold in conical plastic bottles. The idea is that you’ll be able to squeeze the gear lube from the bottle and force it into your diff. Unfortunately, those bottles are rigid and hard to squeeze. You cannot get all of the fluid out of the bottle, so you end up buying more than you truly need to get the job done. Pumps are an improvement, but even those can be leaky or require a third hand to operate without major spillage.

The Mess

No matter your method (pump or conical bottle), it seems impossible to service differentials without making a big mess.

The AMSOIL Solution

The new AMSOIL easy-pack eliminates all of the old obstacles.

Easily access hard-to-reach fill holes. The packaging is flexible. Just bend it until the nozzle is pointing where you need it to be and insert it into the fill hole.

Easily squeeze out entire contents. Empty the easy-pack into your differential with no waste and no mess.

AMSOIL Severe Gear 75W-90 and 75W-140 100% Synthetic Gear Lube (SVG, SVO) continue to provide the same great performance.

  • High film strength for high-load demands
  • Reduces friction and provides the ultimate protection against wear
  • Helps maintain efficiency
  • Well-suited for towing, hauling, racing, commercial use or other severe duty
  • Durable easy-pack makes the job cleaner and faster

A Closer Look at Bypass Oil Filtration

A Comprehensive Look at Bypass Filtration

AMSOIL Bypass Systems offer top-of-the-line protection

Bypass oil filtration features a secondary filter with the purpose of eliminating nearly all contaminants from engine oil. Bypass filters have high capacities and eliminate much smaller particles than full-flow filters. They reduce engine wear and increase oil volume, but their high efficiencies mean they also have higher restriction and must be used in conjunction with a full-flow filter.

How Bypass Filters Work

Bypass filters operate by filtering oil on a “partial-flow” basis. They draw approximately 10 percent of the oil pump’s capacity at any one time and trap the extremely small, wear-causing contaminants that full-flow filters can’t remove. Bypass filters have a high pressure differential, causing the oil to flow through them very slowly and allowing for the removal of smaller contaminants, including soot. It is called bypass filtration because the oil flows from the bypass filter back to the sump, bypassing the engine. This continual process eventually makes all the oil analytically clean, reduces long-term wear and can extend oil drain intervals.

AMSOIL Bypass Filtration Benefits

  • Significantly Extended Engine Life

The majority of engine wear is caused by particles in the 5-20 micron range. Because AMSOIL Ea® Bypass Filters effectively remove contaminants down to 2 microns, engines receive the ultimate in wear protection. Less engine wear keeps the engine in better condition, extending its life.

  • Efficient Small-Particle and Soot Removal

The high-efficiency Ea Bypass Filter element is 98.7 percent effective at removing particles down to 2 microns, helping extend engine life. It is also a very effective soot-removal device.

  • Reduced Maintenance Costs

AMSOIL Bypass Systems provide a dramatic increase in engine protection, helping avoid costly repairs associated with engine wear.

  • Improved Oil Cooling

By installing an additional filter, the engine system has the capacity to hold more oil. With increased oil capacity, the oil filtration system contains more fluid through which it can disperse heat from the engine. This allows the engine and the oil to run cooler.

  • Extended Drain Intervals

Ea Bypass Filters can help users extend their oil drain intervals. Make sure to use oil analysis when extending oil drain intervals.

Outstanding Protection at an Affordable Price – Smartest Passive Unit you can buy

Competing single-remote bypass systems designed for Ford*, GM* and RAM* turbodiesel vehicles range in price from $250 to more than $700, with an average largely over $450. Most AMSOIL Single-Remote and Dual-Remote Bypass Systems carry an MSRP below the market average.

Competing heavy-duty bypass systems range in price from $650 to more than $850. The premium-quality AMSOIL Heavy-Duty Bypass System (BMK30) and DUAL-GARD® Bypass System (BMK22) have MSRPs almost half the market average.
