Why is Synthetic Motor Oil Better?
Synthetic vs. Conventional Oil
Most cars can use either synthetic or regular mineral oil as long as it meets the standards of the American Petroleum Institute (API) and the International Lubricant Standardization and Advisory Committee (ILSAC). But synthetic oils are often sold with the claim that they work better than conventional oils. This may only be true for some of these properties and not for others. Some common mineral oils may work better than others on some properties if they are made in a certain way.
Many studies have been done over the years to compare synthetic oil to regular mineral oil. Most notably, the American Automobile Association (AAA) used certified labs and standardized test methods from the American Society for Testing and Materials (ASTM) to compare engine oils that were sold as conventional and those that were sold as full synthetic.
AAA found, among other things, that, on average, synthetic oils were 47% better than regular oils in the tests that were done. The chosen tests looked at a number of important physical, chemical, and performance properties, such as shear stability, deposit formation, volatility, cold-temperature pumpability, resistance to oxidation, and changes in viscosity caused by oxidation.
See why using AMSOIL Synthetic Oil is Better than Conventional Oil
AMSOIL has been putting out test results for years that show how synthetic lubricants are better than traditional ones. Not just AMSOIL’s synthetic oil, but also other synthetic oils. In this blog post, I talked about some of those tests. In a nutshell, synthetics offer better wear protection, engine cleanliness, cold-flow, and resistance to viscosity loss than conventional oils. That means the engine will last longer and work better.
But our test results don’t convince some people. Skeptics want proof from a third party who is not biased. Here is some proof of why Synthetic Motor Oil is better than Conventional Oil.
The American Automobile Association (AAA), a reputable third-party group, came out with a detailed report that backs up what we’ve been saying for more than 45 years: synthetic oil is better than regular oil. In its test, AAA wanted to find out if it’s worth it to pay more for synthetic oil instead of regular oil.
Yes, that is the clear answer.
John Nielsen, the managing director of Automotive Engineering and Repair at AAA, said the following:
AAA Testing
AAA’s research included eight industry-standard ASTM tests focusing on the following:
- Shear stability
- Deposit formation
- Volatility
- Cold-temperature pumpability
- Oxidation resistance
- Oxidation-induced rheological changes
Five synthetic oils and five regular oils were used for each test. They don’t say which oils they tested, which is a shame.
Extremely resistant to heat
The NOACK Volatility Test measures how much lubricant is lost through evaporation when it is used at high temperatures. The more motor oils evaporate, the thicker and heavier they get. This can cause poor circulation, less fuel efficiency, more oil use and wear, and more oil to be used. The resistance to vaporization gets better as the number goes down.
As you can see, the green bars show that the synthetic oils were less volatile than the red bars (the blue bars). This means that your engine will be cleaner and run better.
Deposit resistance
The Thermo-Oxidation Engine Oil Simulation Test (ASTM D6335) measures how well lubricants resist building up deposits when used at high temperatures. When motor oils are exposed to more heat, they can form deposits that make them less effective and contribute to poor overall performance. The better the resistance to buildup, the lower the number.
In this case, two of the conventional oils did not keep deposits below the minimum standard needed to meet the ILSAC GF-5 specification, while all of the synthetic oils did.
Synthetic Motor oil Out performs Conventional Motor oil
AMSOIL has been saying for years that synthetic oils are better than natural oils. The AAA report is just one more way to show how much better synthetics are for your cars.
Why AMSOIL? Superior protection against wear, improved fuel economy and better performance under extreme temperatures. AMSOIL is the only oil that is able to last up to 25,000 miles. Save yourself time and money and protect your car or truck by using AMSOIL products. Your vehicle will last longer and you will lower your maintenance expenses. Protect your Honda, Toyota, Nissan, Chevrolet, Ford, Chrysler or any other vehicle with AMSOIL synthetic oil!
AMSOIL Synthetic Motor oil protects your car engine because it doesn’t break down or lose it’s viscosity under extreme temperatures and stress. Regular conventional oil breaks down under high temperatures which leaves harmful carbon and sludge deposits which will make your engine wear faster. This is why you have to change your motor oil every 3,000 to 5,000 miles or so at your local dealer or quick lube business which costs you more money over the long term!
