While AMSOIL Signature Series carries the highest initial price, its extended-drain capabilities and outstanding performance make it the most cost-effective long term choice. Those who are not yet ready for extended drain intervals will be hard-pressed to find a synthetic motor oil on par with OE for less money up-front, and XL is an outstanding choice for those who prefer a twice-per-year oil change program. Chose how many miles you accumulate each year and choose the product that is most cost-effective according to your annual mileage.
AMSOIL offers maximum convenience with motor oils that match your maintenance habits. OE is designed for motorists who change according to the instructions in their vehicle's owner's manual. With a drain interval of up to 10,000 or six months, XL is the solution for those who prefer a spring and fall oil change program, and Signature Series delivers guaranteed protection for up to 25,000 miles or one year.
Quality is first priority at AMSOIL. While Signature Series is the premier AMSOIL formulation, the OE and XL lines have been crafted with the same precision engineering to deliver exceptional protection in today's complex and demanding engines. Whether choosing AMSOIL OE, AMSOIL XL or AMSOIL Signature Series, you are choosing an AMSOIL-quality synthetic motor oil with guaranteed performance.
