Premium vs Regular... With some science this time!

[PAW RAPTOR]

Personally, I go with the 91 premium. We don't have 93 here. I usually go with Safeway for gas. I have 3 teenage boys so I have big food bills meaning I almost always get the max $1 off per gallon when I have to let the big boy drink. With the 35 gallon tank, I am always maxing out the 25 gallon limit on that too. I filled up with 91 premium last night at $1.78 per gallon with my $1 off.

premium is vastly cleaner than regular , if you keep you vehicles a long time your smart to use 91

Top tier detergent gasoline’s meet a high standard for detergent content whether it’s premium or not. Stick with top tier gasoline and you’ll be good. [emoji1303]

Really, how so? Premium doesn't get any more detergent then regular.

None of those sources support the claim that Premium fuel has "cleaner" properties than Regular.

For the record, I do run premium exclusively, but not for it's "cleaning" properties, but because when I floor my car, I want all she's got when I floor it, not at my next fill up.

If the engine is designed for 87 it will run clean on 87.

I run my cars on what ever the owners manual recommends which with most of my cars is 91 oct premium and i run 93, pretty much all year long because I'm known to run full throttle to the rev limiter pretty often in my sports cars. Come to think of it i am sure i could run 91 on my sports cars at sea level in winter.....

If however my manual calls for 87...i run 87. I might run 89 or 91 in June to September ie.....hot weather.

My trucks rarely see much above 5,000 rpm....rarely much above 4,000.

Octane is important during periods high boost regardless of the RPMs.

Agreed. Doesn't apply to those of us with 6.2s though.
