What octane gas do you guys use? I believe the tC can use 87 Regular which surprises me since my old GS-R required 91. The dealer put 91 Supreme when I got it, but I've been pumping 89 Plus and do not feel any difference. I've just broke through the 1200 mile break in mileage.

 

lets keep this thread to a poll

no flaming or bashing please!

 

how could you not though?

i use 87... why would I pay more when the manual tells me to pay less?

 

87. Gas prices on Guam are crazy, even on the military bases.

 

This as been done how many times now . . .

 

87 regular at the shell station.

 

87. Tired of paying high prices for gas...we ever going to see less than $1.50/gal again?

 

93 here...

 

im going to pump 87 on my next tank and if i feel no differnece thats what im going to stick with.

 

the manual says 87 will work but if you detect detonation, try to switch to a higher grade octane.

I didn't detect detonation but I let my buddy borrow my car to get to work while I finished turbo-ing his car. When I got it back I had a full tank it seemed to fun a lil smoother/peppier when I wasn't at WOT. So I asked and sure enough he put 93 in. It feels pretty good and I went from 24mpg to 26-27 now since then.

So for the SLIGHT improvement in driveability, added with the SLIGHTLY beter gas mileage, I felt it was worth the small investment more.

 

Just wait kiddies gas is supposed to jump as much asa a quarter in the next few weeks. I saw a 10 cent jump since last night!

 

I have to pay 2.19 for 87 at AMPM. Cheapest in town too.

 

89 or higher. never 87.

 

Anything above 87 is just burning money...but if you have it to burn, by all means run race fuel if you want.

 

Anyone who puts more than 87 in a stock tC is an asshat, and should not be allowed to drive on public roads.

 

89, no way 87 when i first started driving in a 88 camry I used to put 89. No way im going to put 87! u nuts?!? at least I dont have to pay for 91 anymore. :D

 

i have no choice....91 for me.

 

Can I interest you in one of these? You will need to use 91 octane as soon as you install it though.
