Do you use the recommended 89 octane?

Please post any reports of whether you notice a difference in mileage, engine idle, etc....

I would not run your truck on cheese. It will make it constipated.

I use 89. The owner's manual says that the 390hp and 407ft/lb ratings were done with 87 octane though which is awesome to know.

The same tanker that fills up Mobile drives down the road and fills up Bob's gas station.

I will run 87 if the book says I can and let the lifetime warranty worry about the rest.

I have a superchips on my 02 Ram and I have to use Premium 92 or better. I haven't noticed a major change in my gas budgeting with using the more expensive fuel. if I had an 09 I would use 89 or better

I use both, 87 for 2 tanks then a tank of 89 back to 87. I see no difference in power or mileage between the 2 levels

That may be true in some cases but I have seen huge differences in economy depending on which station I fill up at. The cheapest no-name station was getting me about 40 miles less out of a tank with identical driving then a "name-brand" station. This wasn't a one time thing, I noticed it over a course of a year and realized what was going on.

My father-n-law stated the same thing to me last summer come to think of it. He got better mileage filling up a one station near his work verse another.

yeah I'll be honest I'm not one to care about that, I mean gas is gas and it's not like you aren't going to fill up, but there is a noticeable difference between a crumby station and name brand. But to be honest I haven't paid much attention with the ram, it doesn't get great mileage but I absolutely love driving it, I look forward to driving it and that is more important then anything. Enjoy these trucks while we can guys, 10 years from now it's going to be all hybrids with no power lol.

I always use premium... its usually a 20c martkup and i dont mind that.. so on a 30 gallon tank thats only $6 more...

and since im spending $60+ anyway.. whats the extra $6... I felt the difference in my old supercrew and told myself that even if the $6 just barely increases the power, gets me a just a few mpg more or helps things run a lil cleaner in my $45,000 truck.. then so be it

I use 89 all the time......I have used 87 and it really ran no different than I remember the 89....But the fuel mileage will drop about 1mpg or so with the 87..So its about the same difference...

Off site.Me being a tech could go anyware.One day I decided to sneek in this off limit room,I will just play dumb,and they never queston a guy with a tool pouch. Their were about 100 350cuin engines,with 3 guy in white lab coats.Of course one came to greet me.I said wow what's this.He said its the knock room,this is how we tell if it regular or premium gas.Yes no big difference,if it knocks regular.That was good enough for me.
