Use Amsoil and your car or truck will thank you! Superior engine protection under super high or low temperatures. Give your vehicle the best motor oil change ever invented!! If you change your oil yourself then why wait. Don't go to big chain stores and get low quality oil and make sure you are not buying a synthetic oil that is "blended" which means it is not 100% synthetic. Dump that regular oil and move up to Amsoil. Thank you for visiting our page. We also have more awesome products for your vehicle. You can also check out how much synthetic oil your vehicle holds (capacity) in quarts!

How does synthetic oil differ from regular oil in terms of performance and longevity? Synthetic oil differs from regular oil (conventional oil) in several key aspects. Unlike regular oil, which is derived from crude oil and contains impurities, synthetic oil is chemically engineered in a controlled environment to create a purer product with a more uniform molecular structure. This results in superior viscosity properties across a wider temperature range, providing smoother cold starts and better protection under extreme conditions. Synthetic oil also lasts longer between oil changes, reduces engine deposits and sludge buildup, improves fuel efficiency, and offers better oxidation resistance. These differences make synthetic oil the preferred choice for drivers looking to optimize their engine's performance and longevity.
