I usually stick to Hess gas cuz it runs best on that. I brought the truck to a shop where i have family working there and have been going there for a few years and built a few 4x4's for guys there so I dooo trust them. if i didnt they would NOT be touching my truck. I dont know what program they use(mitchell or alldata etc) but i saw the screen, the guy gladly showed me, and showed me a burnt sensor and where the egr port was clogged. i keep up with all the maintence and fluids so this was a surprise to me
(I know this is a old thread) but,
how the hell do you trust a shop that told you a 4x2 hemi uses 87 whilst a 4x4 hemi needs 91 octane. why in the world would 4x4 be different from 4x2 in regards to octane?? u should never trust your family again, let alone the shop charging you 500.00 for labor on the easiest part ever to swap.

I dont doubt you. but it seems rather strange that if you have ethanol free gas, it only comes in high test. I've been told by my brother-in-law, who works for Marathon Oil Company that there is no such thing as ethanol-free pump gas in the USA, but I have no idea about Canada. People advertise such, but he says it all comes out of the same truck, and it all has ethanol, and I really doubt a 1-2 mpg increase just by switching from 10% ethanol gas to an ethanol free gas, or 10% ethanol gas, unless you were switching from E-85 to any regular gas, then I could see that much savings or possibly more. Don't believe that just because somebody advertises ethanol free gas, that is what you are going to get, Good post though, and I can see your rational

If you use 87 from quicktrip, racetrack, 7-11, any place like Bob's for example will be bad for your engine. Filthy filthy filthy watered down gas. Terrible for the motors. Texaco, shell, and Chevron are all very good. I run 89 with those 3 and get about 14 or 15 mpg. 87 would be safe with these guys too but 89 isn't that much more expensive so I do it anyway.

My first fill up when I bought my ram a couple weeks ago was 87. After reading the owners manual and some posts on this forum, my next tank and all future tanks will be 89. There's really no reason to not put 89 in. For 25 gallons, at least in Canada, it only runs roughly 7-8 dollars more than 87. My first fill, on 87, cost me $98, and I filled with 89 a few days ago and it ran me $105, so why not? Just make coffee at home and take a sandwich to work instead of grabbing a bite, and there you go, switch to 89. 
Seems like a good investment to me.

Someone hasn't read their owners manual where it states that 89 is recommended as 87 can damage the engine over time. Now how long is "over time"? Who knows.

I have a 2003 2500 Hemi, the maunal states that: 87 is not recommended... 89 is acceptable. Either way I use 93 all the time, 93 in my area is only .15 to .20 cents more then 87 and the truck likes it better.
