Default What octane are you running?

I didn't even think about it after I bought my truck because the dealer didn't say I needed higher than regular 87. Then my buddy buys one and said his dealer told him he should run mid grade 89 and I guess the manual says mid preferred but regular is acceptable. I havent had any problems with the regular 87.

Let's here what you run.

I just run 87 also, the last 2 hemi trucks I have had I only used 87 octane. It's not a sports car and I have never read anywhere where using 89 or higher does anything. Some claim better MPG but I don't think it's enough to warrant the extra 10c a gallon.

I also was always using 87, til I tried 89. I did notice an increase in fuel economy and also the motor does feel a little stronger. I noticed on a steep hill I drive, that my ram always had to downshift to not lose speed, but with the higher octane I can hold the speed without it having to kick down. I wasn't expecting to be able to notice a difference in any aspect, but I did. I also read somewhere that with the 87 octane, the computer has to adjust the engine timing, which negatively effects economy and power.

87 octane here too. No reason to go any higher right now.

Now, I have heard that running higher octane all the time in vehicles that aren't meant to run it may cause problems down the road like the O2 sensors going out, plugs burning up and so on. Now before the hazing begins, this came fro a dude that refuses to run the A/C in any vehicle he is in because it may causes skin cancer but chain smokes Camel non-filters with the windows up in the same vehicles I am referring to...

The hemi will work fine with 87, but you won't be running at 100 efficiency and power. The hemi is meant to run on 89 octane. High compression motors need higher octane to run optimally and to keep the fuel from igniting prematurely or knocking.

Got this from wiki "Due to the large variation in fuel quality, a large number of engines now contain mechanisms to detect knocking and adjust timing or boost pressure accordingly in order to offer improved performance on high octane fuels while reducing the risk of engine damage caused by knock while running on low octane fuels."

after reading everything, I think I'll try 89 and see what happens. I'll post the results in a few months.
