Well, just curious which octane do you always get, and with what engine?

I did a search, but most of them seemed to be like which gas stations do you usually go to or just which gas do you usually get, but not much with answers as to which gas you get and the engine you're running. Like is it ok to use 87 gas for b16s or b20s for example? Or do you run a risk of messing up the engine in the long run if you don't use premium? Thanks in advance.

 

i use 91 in my b18c1

 

91, highest I can find around here.

b18c1 with drag kit.

 

well i advanced my timing, and i was told that i have to use higher octane so i get 93, thats the highest here in ga.
i like to go to qt for some reason
oh yeah, b18b

91 in the gsr. do b18b's require premium??

 

for the best results 91+

 

factory recommendations are 91 octane, but i get 93

i notice that when i put in 89(just once though)

gas mileage really hurt bad, i think it was like 19 or whatever, i normally get 27+
but i was running m@d vt3k y0!

 

it doesnt hurt the engine to put 87 in but at least in the b18c1 you get bad performance and milage. i go for 92-93 when ever possible

 

i take the highest i can get...

~91-92 for me

 

87 when 89 is too expensive.

 

over here (Germany) they have 98-100 so thats pretty much what i use in the LS and the TSI.

 

93 .. i heard we should be getting a Sunoco nearby soon so.. i'll be using 94

 

Either the Super Mobil or the Exxon Super (they're the same now anyways, lol)
My friend who's a mechanic only drops regular in his Supra ( A FREAKIN TWIN TURBO SUPRA) I think he's nuts

 

Only reason to put high octane gas in your car is if you have a really high compression engine or turbo. higher octane gas will help prevent detenation because it is less votile. Common misconception is you will get higher performance with higher octane, gas company's make millions off this idea.

B18C engines have high compression and will retard the timing if it senes any knock. So if you were to put 87 in your GSR, you might notice a change in performance as the ECU is retarding the timing.

Any other engines are fine to run 87. If you do notice a change in gas mileage when going from 87 to 93, then detenation is occuring when your running 87.

 

My engine must be retarded then.

always 93 or 94 in my 99 LS

//Alex

 

anywhere from 87-91 depending on price

but normally 89 oct

 

Chevron 93

 

i only run mobile 93 one time i ran 93 from this little circle k and i noticed that it didnt run as well and seemed to bog even more in the low end (skunk 2 im)

 

i use premium, 91 or 92....try to find higher stuff around here in minnesota.....kinda hard to even find 93

find an airport and fill up...i think airplane fuel is at least over 100

 

10-12

 

Texaco 92 in my b18b

 

I care ot give osama the least $$ I can- I use regular and once in a while when it is cheap premium. 98LS (I get better milage on regular)

 

If I'm going to burn through a tank on a drive I'll do 89, the rest of the time chevron 93. If they sold 91 between 93 and 89 I'd go with that most of the time, but gotta love texas for the 93.

 

well when I had supercharger!

Fl----100 or 93 octane wirh octaine booster
MD,VA,VA----93 with octain booster
NV---91 or 100 with octain booster
