Hi,
I am a new owner of an E92 M3 and was just curious about what gas grade I should be using daily?
Obviously premium, nearly every station has 91 octane premium, but some petro canada's carry 94 octane, and then there is also shell v-power 91 octane available (I dont think 94 v-power is easily available, i know 91 is).
So essentially, it is brand new and just want to know for daily driving do i have to be fussy and only put 94 octane, or should i always put 91 v-power...i know some people swear by this.
I bought the car, so I would like to keep it running as it was intended too.
thanks again

 

If 94-Vpower was available her in Orange county I would use it in all my car, I put 91 octane.

 

thanks...
after doing some research, here is what is availble.
a) premium 91 octane
b) premium 94 octane
c) v-power 91 octane

what should i use as a daily fuel, i assume that it will be between b and c.
of course, if 94 octane v-power was available that would be a no-brainer, but it's not.
so thanks again

 

Higher octane fuels can't hurt (except the wallet) whereas lower octane fuels can.

 

thanks, my main question though is whether the v-power at 91 octane is superior to the Petro-Canada 94 octane (not v)...
both practically the same price.

 

I voted shell 91, but upon looking it up found that Chevron is also approved as a top tier fuel so I'd go with chevron 94.

 

sorry, i made a mistake, its not chevron 94, its petro canada 94 vs shell 91.
sorry for the confusion, but petro canada is top tier as well.
TOP TIER Gasoline Retailers:
QuikTrip
Chevron
Texaco
MFA Oil Co.
Conoco
Phillips 66
76
Entec Stations
Shell
The Somerset Refinery, Inc.
Kwik Trip / Kwik Star
Aloha Petroleum
Tri-Par Oil Co.
Turkey Hill Minit Markets
Mileage Stations
Chevron Canada
Shell Canada
Petro-Canada
Sunoco Canada



I ASSUME THEN, IF SHELL AND PETRO CANADA ARE BOTH TOP TIER, THEN THE HIGHER OCTANE PETRO CANADA WINS?

 

i agree with rogue.

 

I usually put the highest available which is 93. I try to fill up at chevron and then if not there is usually a shell or BP in the area. Gas just keeps getting worse and worse as the oil companies dilute it and reduce the additives. It's all basically the same stuff except the additives. Even those aren't that different.

 

put the highest if you could. 94

 

so shell's v power blend doesnt beat out higher octane fuels? essentially the question, is 91 vpower superior to petro canada 94, top tier as well? i am more curious than anything, as i have always heard how amazing shell vpower was, but was wondering whether its even better than higher octane fuels...
thanks again
drove the car in a 30cm snow storm yesterday....amazing.

 

I normally put in 93 or 94 octane depending on the gas station and we also have 100 octane available but I never put it in this car. Turbo charged cars we do.
