Gas Grade

Does it really matter? My friend said that he put a higher grade like 92 because he said it burns better and the gas last longer, but doesnt it equal the same because your paying more for the higher grade 92 octane? Unless he just wasting his money on getting a higher grade?

 

Regular 'ol gas in all my trucks and never once had a problem. Dont waste your $ on more expensive octane unless your engine requires it by design, or by adding sc/turbo/etc.

 

^^^This.
Pretty much only needed for advanced ignition timing or higher compression.

 

So the gas doesnt last longer than right?

 

hurrrr

Different gas doesn't matter.

I tried it. Didn't make any difference. Switching back didn't make any difference either.

It was on long distance driving as well.

 

The only difference is gasoline containing other junk, like ethynol... I get the best mileage out of Pemex gasoline in Mexico (87 octane)... without the enviro green crap they add in California... that reduces mileage and makes us burn more fuel!!??
