Just reset the car's ECU, it'll remap itself usually on most modern cars.

Originally posted by lücid should i be using 87 or 91 octane gas in my car? it's a 2003 VW Jetta 1.8 turbo. the gas cap says 87/91, and the opinions seemed to be pretty mixed on the VWvortex forums. some say use ONLY 91, others say it doesn't make a difference what you use. is it better for the engine/turbo to use 91? plz essplain... i didn't wanna ask on VWvortex 'cause i feel out of my element, lol.

I have the SAME EXACT year, make, and model - I use 93. Never use 87 on a turbocharged car. 91 is iffy, but you'll get by on it.

What's your username, on VWVortex?

Yeah, I edited, because I accidently deleted the bracket to close the quote script.

i think it's lucidmyra. i forget... but lucid was taken. i've only made one post on there, and it was in the Milwaukee thread.

for those of you who are saying "NEVER" use 87 on a turbo, can you explain to me why you say that?

Lower octane gas will leave more build-up and some people are extremely passionate about their cars and never want to give their car an inferior product (which, technically 87 is).

The thing is, most cars are built to run on 87, and they do perfectly fine on 87. I have friends with old piece of shit cars and they never put 87 in them. It's a waste of money because there really isn't anything wrong with using a good quality 87 gasoline (just don't buy it from Arco) - that's some dirty gasoline.

umm Curious now, in terms of pollution, is it the same to use 87 as 91? or it has no connection whatsoever?
