I been driving my 914 this summer. Closing in on 5 Kim so far this year. When I go, I get the highest octane that I can find; 91 or 92 with no EtOH where I live, trending towards more ethanol as we get west. So, I have been old guy writing down the numbers and have consistently hit 31 -32 mpg. This decreases if I leave my gas cap off just before a drive with the RRC 2024 folks.
The interstates let you drive at around 80 mph, and that adds up to a light throttle 3,000 rpm with my gears. The car must be pretty good with airflow. |

My 71 2.7 twin plug with webers might see 14 mpg if I’m lucky.
At least it beats the 74 911 with an RS2.7 MFI, which I’ve yet to crack 13mpg. It’s prior 2.7 CIS moto saw 25 mpg. All on ethanol free fuel. When I road tripped the 3.2 conversion I saw 23mpg. How in the hell are you seeing 30s? |
