100 octane gas?
I'm thinking of trying it if its safe. My car is pure stock. Would it make a difference? Is it safe?
Sorry if this is a dumb question and thanks for looking!

You will real havock in neigborhoods across your town. Flames will shoot out of your muffler like a snarling beast. Children will run to their mothers crying due to the horrific sound being eminated from your car. There will be an apocalyptic presentation of pure German engineering upon the luminescent appearance of a green light at every traffic stop. Idk, lol. |

Thanks guys! Guess I should upgrade the JB3 I have from my last car and give the race gas a chance.

But all you will be doing is wasting money, octane levels over BMWs recommendations will make no difference at all on a stock car.

I run on 103 often but I have JB4 and it makes a huge difference. Car runs great on higher octanes as long as you have a tune.

A 76 gas station in Irvine, CA has 100 octane at the pump. I did a 1/3 mix with 91, and my butt dyno definitely felt a difference.

what about lowering the octane ,, i used to use 95 but someone told me that i can use 90 instead of 95 and use small bottle (i can buy from any gas station ) that raises the octane level. thats because 95 is expensive in Jordan compared to 90.
so will this make any difference to car performance or will it have any bad effects ? |

Its probably not going to make a difference unless your having timing corrections. But most likely not. If you were tuned for 100 octane it would make a difference. A local gas station near me sells 100 octane cam 2 and I tried it once while using COBB stage 2+FMIC. I cant say I really felt a difference. And it cost me $9.99 a gallon which seems like a real rip off.

Not entirely true. You will get somewhat of a difference, but not noticeabley enough to run it consistently.
