AMSOIL Product Change Interval Guide
Most AMSOIL motor oils are typically designed to last up to one year or 25,000 miles. AMSOIL does have a one year 35,000 mile oil called our Signature Series 0W-30 (SSO) and also a less expensive 6 month or 7500 mile XL motor oil.
It is very important to note that the previously stated maximums are under NORMAL service conditions. To make sure you are using the product correctly to provide the best protection you need to refer to the AMSOIL Product Change Interval Guide.
This product change interval guide also has the recommendations for the AMSOIL air and oil filters, automatic transmission oil (ATF), powershift transmission oil, and gear lubes.
People always ask "how can AMSOIL do such dramatic extended drain intervals?
First AMSOIL is the first in synthetics and continuously raises the bar when it comes to synthetic motor oils as proven in numerous motor oil test comparisons.
Plus in a special report released in May 2006 by the Motor & Equipment Manufacturers Association (MEMA), they state that synthetic motor oils are key to extended drain technology: “Extended drain technology is primarily based on the availability of synthetic oils. While the additives in conventional, non-synthetic oils allow them to function longer than the tradition 3,000 miles, it is primarily the synthetic base stocks that allow the oil to last much longer. Synthetic oil offers many advantages in durability versus conventional petroleum oil and it is all based on the synthetic oil’s superior heat and oxidation resistance. Synthetic oil is more accurately controlled at the molecular level and therefore can be engineered to resist the forces in an engine that work against oil durability.”
