Would a higher grade gasoline give me better gas mileage?

I have a 96' Chevy s10 blazer and a 92' Chevy s10 pickup, both of which dont get the best gas mileage, but I use the blazer to drive 37 miles one way to work and would like to maximize my gas mileage in any way. I currently get about 18mpg.Would a higher grade gasoline give me better gas mileage?
Longer term a better brand of gas (whatever octane your car requires) should because the "Top Tier" gasolines (see link below) have more of the expensive additives that make a difference between the gasoline brands. I like Chevron with it's patented Techron additive which is in the same strength in all their gasolines.

No and it may damage your car.Would a higher grade gasoline give me better gas mileage?
No, just a bigger fuel bill. Most auto built in the past 10 years were designed to perform best on 87 octane fuel
Simple answer is no. All it will do is waste money to use over the octane needed for your engine.



To save on fuel, watch your speed, drive as if there is an egg between your foot and the gas pedal, and don't break the egg. Look ahead to avoid having to brake early, and keep your tires inflated to the right pressure.



18 doesn't sound bad to me, I get around 9 with my 454 in my tow truck.Would a higher grade gasoline give me better gas mileage?
no,,,, all high octane gas does is keep away "ping" on high compression engines
Yes it would, and also changing your oil every 5000 KM or 3000 miles improves gas mileage big time.
Buy your gas at a branded station, which means 76,Chevron,Shell Etc. They have additives in their gas. Cheap gas stations have no additives, they all have the same octane,try a higher octane at one of the branded stations and see if you mileage goes up. Make sure your air filter is in good sharp and check your manuel to see when a tune-up is due. All these items will increase mileage
no it wont do anything to ure gas mileage it jus depends on ure compression ratio and ure sprak plugs wut grade u use u shouldnt use grade that isnt recommended by dealer
Yes. it's burns hotter therefore less fuel needed to go the same speed
