right know im runnig 89 gas and just regualar standard oil, i want to switch to full synthetic mobil 1 and premium gas, with gas prices in chicago going up and down every min its gonna be kinda expensive but i think my car will like it alot better. will i notice any diffrence or is it just to pamper my car.

 

well i always run premium in the max, but i had my fiance try premium after doing regular gas and she won't go back, there was a pickup in accelleration, and she got better gas mileage in the city. There was a post just after gas skyrocket that said lower grade gas is better for highway and higher grade is good for city driving...

 

You will notice better performance with the premium, but it will take a couple of tanks for your computer to adjust, so don't expect to feel it as soon as you drive out of the gas station. I have only run premium in mine and thats all I ever would because I drive it pretty hard.

Go with the synthetic, it will last longer for sure, but just remember not to many oil filters will last as long as synthetic oil will.

 

awesome...perfect response
