Full Version: what octane gas?
Hello, the sign by the fuel tank inside the front trunk/hood says use 91 octane gas what do you all use in your cars???????????????????
Regular. The 91 reference is a different standard
Leaded if you can find it. 
Leaded gas was never needed in 911 or 914 engines.
IF you can find pure gas (no ethanol) 87 regular will make it run like a top.

91 RON. RON is a Euro standard, and 91 RON closely approximates 87 in US.
Stock type IV engines have pretty modest compression ratios, so all you need is regular gas. Non-ethanol if available.
does anyone use octane boosters?
what about for a 2056? It's hard to find anything over 91 RON around here
