I was wondering what most drivers are using in their 914's. 87, 92, 100?
I have heard that in fuel injected cars running with a higher octane gas than they were designed to run at can be a waste of money since they are set up to run on a specific octane and any more is lost. I have a Passat and the manufacture states 92 octane. My truck uses 87 and the dealer said I can do damage by running 92 ( although I have no idea why). Please set me straight on my ignorance.

Thanks for all the input.
I have been running 91 octane in my car and it seems to be running well. I am going to drive the hell out of my car this weekend and wanted just a little more. The local 76 station sells 100 octane at the pump so I was thinking of running it hoping for just a bit more power. At @ $4.50 a gallon I was trying to decide if the extra octane may be worth some extra power. From what I can take from the answers I feel that I may just stay with the 91 octane. I am running a 2.4 litre 6 from a 1973 911S with MFI and the compression is 8.5:1 . It runs like a raped ape with the 91 octane but I just wanted a little more kick for the weekend. For a extra $2.00 per gallon, I thought it might be worth a try. |
