Weird thing with gas mileage
Hey all i got the 4.7 in my ram and last week i filled up my 34 gallon tank with premium (91 octane) just because i have been running regular (87 octane) and it was really weird, my drive to work is 30 miles one way and usually when using regular i will use approx 1/8 tank just getting to work. no when i filled up with premium i went to work and home from work on less thna a 1/8 tank.. i just found this weird so this week again i put premium in again and its still doing in.. i ran 91 just to help clean it out but it seems to be getting me way better gas mileage.. i would apperciate any thoughts into why you guys thing this is happening it just weird to me.. in my other cars i would run premium like every fourth or fifth tank to clean it out but nothing like this happened before.... thanks for you input in advance

Ive had the same results on all of my cars & trucks in the past. better to just get premium to begin with. another thing to mention is that if you buy gas from crapstations, you get worse performance in the mpg area. I always used Chevron or Union 76 premium.
I wouldnt be supprise to here you got 1 mpg better.
another thing that will help on the hiway is a tonneau cover. I just had mine installed on the 3rd gen ram and it's getting about .75~1.0 mpg better than without it (on the hiway).

RE: Weird thing with gas mileage
i have an '05 4.7 QC too and i've noticed the same thing. Have you noticed an increase in acceleration or are you the common "soft-foot"? lol
i dont know why it happens but you are not the only one. the only complaint i have about using premium all the time is that my custom glass pack duals are quieter and sound more muffled and rumbly with premium. and when i run on regular it is louder, hurts your ears, gets you noticed and has a lot of bang bang pop pop coming out of the back. the bang bang pop pop is why i started using premium in the first place. anyways i get picked on and laughed at and called stupid but i can swear to you.. i get better gas mileage and performance with it. people are like "no the gas won't give you mpg and performance" because they are stupid. they don't understand im trying to say its the MOTOR that responds to the gasoline and does that.
sorry for rambling. im bad at that lol.

yea i only use chevron and from now on im only gonna use premium cause like b3nzyme said their more acceleration and when i crusing on the high way the meter is higher than normal.. yea i understand what your saying the grade of gas makes a difference my dads a ASE for 30+ years and he says it cant hurt and actually your only gonna clean your engine and help it..so for the extra 6 so dollars per fill up i see it as worth it. too me im already paying 90 per fill up whats another 6 right!!!??? yea those crap stations suck i used to use 7-11 before on my station wagon but it ran like ****, chevron is the only thing i use..

RE: Weird thing with gas mileage
So just for my clarification: running 91 instead of the recommended 89 won't hurt my hemi?? Also, is there an easy way to find out what gas stations in town are 'good' vs 'crap'? There's a station in town that sells 91 at the same price as 87, seems like a steal of a deal but I don't trust it so I don't go there. We have some shell stations around and a Super America, that's where I usually go. Do the stations say somewhere that their gas comes from BP/Chevron etc.?

RE: Weird thing with gas mileage
I got some news for you guy's. There is no difference in the additives in the additives between 87 and 93 octane. Different brands use different additives, like Chevron uses Techron. Also high octane, 91 and higher has a slower burn rate than regular, thats why it doesn't knock in high compression engines.
87 octane burns faster so it is better for lower compression engines. I'm not saying weather or not you get better milage with permium, but a lot of times burning a higher octane fuel in lower compression engines will just dirty or soot up the combustion chambers because they can't compleetly burn it due to the slower burn rate.
