What is the difference between regular oil and conventional oil? Regular oil, derived from crude oil, contains impurities and undergoes minimal processing. In contrast, synthetic oil is chemically engineered in a controlled environment, resulting in a purer product with a more uniform molecular structure. Synthetic oil offers better viscosity properties across a wider temperature range, providing smoother cold starts and superior protection under extreme conditions. It lasts longer between oil changes, reduces engine deposits and sludge buildup, improves fuel efficiency, and offers better oxidation resistance. Overall, synthetic oil offers superior performance and longevity compared to regular oil, making it the preferred choice for many modern engines.

Protect your vehicle with the best synthetic motor oil change possible as Amsoil is fantastic for reducing friction, temperature, and engine wear! Your car will thank you! If you need to know the capacity of your engine, then you can find it on this page. It is listed in quarts and make sure you get an awesome filter to go with the oil. Don't change your own oil? No biggie, just take the quarts recommended for your car and the filter to a mechanic who, if honest, will gladly change it and should charge you only 1 hour labor. Use Yelp or Google to search for a mechanic shop near you! Buy now and support American oil and jobs!
