94 chevron - 01 M3

'90 RX7 (not stock)

94 Chevron

87 octane from shell. manual says to use it 94 si

92 from chevron

01 civic si Husky91/92 <- cheap =) but is it good?

Chevron 94. Car is tuned to it specifically.

04celica gt
89 chev

your 1zzfe doesn't need it. unless you advanced your timing a bit?

07 vw gti APR tuned for 93 octane, so 94 chevron only or else engine go boom :cry:

Really? I have an '05 and it pings on anything less than 91. I'll try 89 occasionally, but I have to baby it to prevent that from happening. I thought they even raised the compression on your gen.

00 Cavalier with L67 engine swap = 94 octane, wherever I can get it since it's all from the same refinery (we only have one in Vancouver...).. tune & blower makes engine go BOOM if I use anything less..

98 Cavalier with 03 Ecotec swap = 87 octane, no point in wasting money

in asia octane is measured in RON, which means u are filling up with 99ROn, which is just a 93octane gas.

On my fuel door the sticker says 95RON=91Octane

87 chevron

Just use whatever is recommended. My Spec-V recommended 91, so I gave it 91. It can retard timing if lower octane is used, but that also impacts performance negatively. Driving it on 87 was ass. My current car, the Prius, only sips 87, so it's a lot easier on the pocketbook.

Really! Absolutely zero problems with 87 and the engine pulls hard with it
However I believe the Spec-v requires premium

87 inna gixxer?

91 350z.. sometimes 89.. never seee a difference

i did fill up with husky 94 a couple times..ntoiced i got 320 miles to a tank..then i used chevron 91... and got 350miles to a tank... happened more than once as i kept testing it. havent used husky in a while now and i wont again...
chevron or petro :)

Chevron 92 only

i got tricked into thinking techron was useful.

I have the Spec-V and the engine is identical.

doesn't the spec v engine make like 20 more hp over the SE-R?

only stupid people think motocycle needs octane 94 or higher because of the high compression.

I used to put 89, sometimes 87, in the R6 and it screams healthy at any rev. Octane 94 actually gives you worse milage

I've used 87 for everything... Yaris, MR2 Spyder, ZX6R, even the RX8.

On the previous gen (b15) it's only 5 hp. The difference is a supposedly less restrictive muffler. Same engine.

in the Z3 - 94
in c280 - 91
