When do you need to change your oil on your Chevy Trailblazer?

The GMT360 platform trucks (Trailblazer Envoy Bravada Saab 97x) use the oil life management system. If it is reset at each oil change interval it is an effective method of not wasting money and getting full value for your money.

We have lots of info at our enthusiasts website

The Oil Life Management systems works, but many mechanics and engineers I work with swear by 3,000 miles for conventional oil and 5,000 to 6,000 for synthetic. I change my synthetic oil every 4,000 miles. I have torn down enough engines to know that oil is cheaper than engine rebuilds and although more frequent oil changes are more expensive, it is worth the extra cost to me to keep my engine cleaner and this run better and longer.

Trailvoy.com is a great website too by the way.
