Get awesome oil and save time and money while protecting the environment. Synthetic motor oil has been proven to be better than regular motor oil. You will enjoy longer intervals and protect your engine even more! It is a win win! Make the switch to Amsoil! Even if you do not change your own oil, you can take it to any mechanic who you trust. Be sure to buy the filter that matches with your car or truck to the mechanic. (Should only cost 1 hour labor so buy now.) We also have synthetic transmission fluid for your vehicle and the capacity is listed on this page.

Synthetic oils provide an improved cold start, partly due to their lack of waxes found in conventional oils but not in manufactured ones, which thicken when not in use. By smoothing the start, synthetic oils decrease your vehicle engine wear and improve its fuel efficiency.
