Today's motorist is confused. For several years GM and several other car manufacturers have been installing a monitor that uses a light on the dash to indicate when it's time to change oil. But oil companies and oil change facilities continue pushing the 3000 mile oil change interval. What's a car owner to do?

The right approach is to follow the light, and to use AMSOIL XL, the one oil designed for today's OEM approved extended drain situations.

With AMSOIL XL you still get all the other benefits of a premium synthetic motor oil including:

• Superior wear protection so that engines last longer
• Improved fuel economy... More miles per gallon
• Easier cold starts
• Cooler running engines in high heat
• Reduced engine deposits
• Resistance to oxidation and thermal breakdown
• Increased horsepower
• Superior shear stability and film strength

In short, with AMSOIL you get the best of everything: the convenience of longer drain intervals and performance benefits galore. Plus, it's better for the environment as well.

Manufacturers of petroleum-based oils have insisted that oil needs to be changed every 3000 miles, even for these modern vehicles with the light. Why not install an API Certified Synthetic Motor Oil that specifically states that it can be used for 7500 miles or six months, or longer if the OEM oil light sensor indicates as such. AMSOIL synthetic motor oils have been designed to go far beyond the requirements of engine manufacturers for peace of mind as you travel further between oil changes.

AMSOIL XL Synthetic Motor Oils is available in SAE 5W-30, 5W-20, 10W-30 and 10W-40 viscosity grades.

According to a feature story in the May 2004 issue of Lubes N Greases, "vehicles equipped with the OLS no longer specify or recommend any mileage interval for oil changes."* As we enter 2005, more and more cars will be going 10,000 miles and beyond without the light going on. GM has finally cut the cord. In 2004 their "April is Car Care Month" campaign advertised that the 3,000 mile oil change may be unnecessary. The alternative today is total reliance on their patented Oil Life System (OLS).
