I went 8 k miles on a oil change. On purpose to kind of test
Amsoil XL Boosted. I'm a stickler for 3-5k miles and I preach it to you all the time.
The oil was not any darker than normal. Didn't smell burnt or fuel diluted. I didn't lose fuel mileage and the engine was still running normal and no weird sounds.
