Petroleum Choices

HEK

Here in MA, we have Pride gas which is the cheapest in the State, actually next to the cheapest as which is Cumberland farms and it's 93 octanes and I see numerous Mustangs, Vettes, etc high end vehicles gassing up there so I think the gas moves quite well.
Funny how we worry about what kind of gas we use but we have the worst "diets" for ourselves, all we have to look is around us and see it...

For street duty I only use Chevron or Texaco 93 octane I have done several engine tear downs and found clean looking engines with not a lot of carbon build up the additive (Techron) Chevron and Texaco gasoline’s use makes their gasoline a excellent cleaning gasoline. For track duty I use VP Racing Fuels Motorsport 100 (MS100) or 76 gasoline 100 octane both were found to be excellent fuels to use at the track. Nissan highly recommends using “top tier” gasoline’s in all Nissan and Infiniti models. Also I would hope everyone is using 91+ octane in their Z since over time engine damage is possible using lower octane fuels. Definitely be selective what fuels you are deciding to run in your Z.

This is what I was talking about earlier about gas being gas, but the additives is what sets brands apart. I will drive a bit further for Chevron gas bc of the Techron additive.

I've definitely had the thought "if I took care of my body like I took care of my car..."

It's always been body mind and soul. When in reality it should be: body, mind soul. . . AND car.

Used to fill the tank with Petro Canada 91, the mother company is Suncor, which is Sunoco in US.

Then heard about the 0-ethanol thing in this forum thus give the Shell 91 a try..

the engine actually runs better plus a tad better gas-mileage.

Thus Shell 91 is the 1st choice, Petro Canada(Sunoco) 91 is the 2nd choice.

I avoid Esso as much as I can cos it runs the worst in my experience..

This Is VERY Interesting To See What You Buy & Why - THANKS

Update: I "Made The Rounds" In My Area Looking For Gas
Passed Up Citgo, Valero, Gulf Cuz Stations Were "CRAPPY"
Filled Up At A Nice New Sunoco Station With Ultra 93 (Ethanol)
My Only Other Choice Is A Truck Stop That Has 91 Ethanol Free

Never Used To Be This Hard To Get GOOD GAS! - .

one question we have not asked ourselves is if the gas we use has any ethanol and how much, I just saw a video on youtube "Scotty Kilmer" and he sure makes sense ...now back to the topic on hand

Some good info here most of all the gasoline brands you will find in the United States will have up to 10% ethanol mixed into the gasoline it is hard to get around it but, there are some places like certain areas of Canada that have ethanol free gasoline brands you have to shop around. Also all the grocery store brand gasoline stations I have seen use generic additives in their gasoline’s that is why it is slightly cheaper and I have talked to the fuelers before for the grocery store name brand gasoline stations and they confirmed and have even showed me their paper work the gasoline additive they use is a generic additive. In my opinion I would not use any grocery store brand gasoline even in my lawn mower let alone my Z. With gasoline you get what you pay for. For us guys here that go to the track it would be a bad idea to put low quality/cheap fuel in your Z it could damage your engine it is very possible this is why I am selective what gasoline brands I use in any of my vehicles.
