Which gas is the best to pump? Which one takes longer to burn?
Longer lasting? Well, I get better mileage in my WRX with 76. However, I get better mileage in my Corvette with Chevron. In my truck, it doesn't matter what I feed it. Of course any mileage differences could be coincidental since obviously I'm not going to treadmill the cars. However, it's accepted among many car enthusiast circles that Techron is the best additive. (That's Chevron's)
The more additives the worse the millage you will have. Chevron is the best out of the bunch.
