I'm going to kick myself for asking this, but...

Ok, so I'm aware that the fuel in Germany is 98 RON, which is around 92-93 octane, and they offer a 95 RON which is about 90-91. My question is... since I'm being warned about the price of gas in my area where I purchased a home, and my car is currently tuned to 91 octane from CA, would I be able to get away with running the 95 RON which is equivalent to 91 octane until I get an updated tune and actually get the higher octane like I should?

 

I always run the 98 ron here. Do what I did, run it and as soon as you can get TTP to tune you with the Germany gas and a tactrix cable.

 

Cool, thanks mump.
