eh ive been running 91 shell vpower in AZ, thing still pulls timing, its not much, and its not a huge deal, but im thinking of filling up with 87 next tank just to see if i can notice the difference, because i can certainly notice the price at the pump sort of negating the MPG increases vs my old car. I put 91 in right off the bat so im curious if it actually drives "bad" on 87 when its stupid hot out.Keeping this in mind. I've had my 2012 Cruze LT for about 3 weeks, and I've noticed the sluggish starts and occasional hesitations in the first couple of gears. I live in AZ, and I wasn't aware of the octane sensitivities, so I think I'm going to start by running a few tanks with 91 ocatane and see if that makes any difference first. Once I know whether or not that seems to matter, I'll consider attempting this change next. I'm a computer engineer, so relatively capable, but only have experience doing rudimentary auto work so far, mostly electrical. I've changed and gapped plugs on my lawn mowers before, but I assume this is considerably different.
I honestly dont think anything is going to matter when its 110-115 out.
Ive heard theres a place called the thumb in scottsdale that has brisket sandwiches and good food and also 95 octane and its possibly ethanol free (though i think the turbo would like ethanol in high heat?) havent made the drive there yet to check it out for myself, worst case scenario id grab some food if it turns out to be standard gas and a racing gas pump with 103 (hmm could i?) i doubt the price would make it worth it though.
My car has under 2k miles on it, and ive sort of gotten use to the bouncy acceleration when its pulling timing, which oddly enough seems to happen most within the first 10-15min of driving, that or i just get use accelerating to avoid it.
Hopefully the car runs better when the temps start to drop to a reasonable 100 and below, even then the bouncy acceleration ive already gotten use to and just ignore, and its only sometimes....as long as its not damaging anything im done caring about it.
