oh yes, the dealer thing....Im thinking that 100 was probably over a very long time. could have been spread out, not at once. Nothing to do with Stabilitrac. So your truck actually bucks? wow, there must be something wrong. I would take it back and tell them it bucks at low rpm at whatever speed. They might actually do something.
Do other peoples trucks buck too? Mine has never, ever, even came close to, bucking. Lugging, yes, that is a good description of the low rpms the truck likes to drive at. NOT bucking, or even chugging. lugging ya.......
If we list from low to high, lugging, chugging, bucking, my truck had a few rare bucks, mostly chuggs and on good days just luggs. I was able to notice them from the passenger seat while my wife was driving. I guess I had a few lazy ponies that did not want to do the work
My truck runs fine on 89 octane, I've never run 87 in it. I would be surprised if the dealership didnt fill it with premium before I took it home. I have always run 89 or 91 in my vehicles, once had an old beater monte carlo that would not run well for long on 87. The difference in cost from 87 to 91 octane is only $.20, comes out to< $4.00/tank. Not sure why anyone would be against spending a few $s more /tank, but would rather buy an expensive contraption that would really benefit from 89 or 91 octane fuel.
It's not about being against the extra cost, it's more like the "have to" if you want the engine to perform well. We shouldn't "have to" unless the manual says so I guess...
The price difference it is not that much, especially if you can squeeze a little more MPG out of the higher octane. So far the numbers on my DIC for the 93 look good, averaging around 20.1 on the same route I used to average 18.3 with 87. I am very curious what it comes out to at the next fill-up (miles driven/gallons pumped). With 87 the computer was off +1 MPG.
