What type of gas do you run in the "Tank"?
I ran 87 for awhile and switched to 93. Man what a difference. Some people think the a higher octane gas has a higher ignition temp. Which it does. And that it is bad for your motor, leaving carbon buildup on the pistons and etc.... I ran a tank through and it seems to have more power and somewhat better fuel economy. How much you paying for 93 now? I'm paying 1.93 to 1.99/gallon.m4ck said:I ran 93 and 95 we have available here where I live until reading around some forums and decided it didnt make a difference. If so it was a minimal difference. If I notice its starting to ping I will change back. But for now with prices the way they are and my truck running fine with 87 I will just keep using it.
My owners manual says 85 is okay at higher altitudes.OldSalt said:Don't cringe when I tell you all what I burn in my truck....85 octane regular. The octane ratings here in Utah are 85 (reg), 87 (mid) and I think that the premium is either 89 or 91. When I first moved out here about a year ago from FL, I was concerned about burning the 85 octane regular in my 4.3L S-10. Stopped in at a Chevy dealer and asked about it; the tech I spoke to said it wouldn't hurt anything and that he burned the 85 in his Silverado. So, that's what I've been using. I haven't had any knock and/or pinging in the Titan, nor in my wife's Sante Fe. BTW, I'm at about 4400 feet here in the Salt Lake valley.
