The S4 gets like 28highway and i average 22 on 50/50 driving. The Cobra prolly averager from 18-20 with mixed driving.

 

My average is sitting at 32 in my S4...but most of the time i see high 30s while driving. This all based on what the screen tells me and i dont get on it much

On my way back from picking the car up in NJ it said it was 31 mpg average at 70mph. I dont think i believe that though.

I watch my MPG very closely. I get about 18-20mpg average. The best I've gotten is 25mpg on the highway. I've got a SOHC 4.6l with all the bolt-on's. What hurt my mileage the most was my 4.10 gears. Now that I paid off my Stang I'm thinking about getting an electric water pump and aluminium drive shaft. Maybe that will get me 2mpg better. Not great, but I love to drive it and no payments mean I can spend a little more on gas. Lighter rims, a tubular K-member, rear seat delete, racing seats, and other lightening things should help as well. Should offset adding a roots supercharger in the future ;)

There's no point unless you removed your OMP, or it went bad.

 

I guess he had a very faint rattling noise or something that he could never figure out and neither could the dealership. The noise stopped after he started premixing and he says it runs much smoother. I don't know if it is psychological or not, but he said that many people on the RX-8 forums are doing it too.

 

I know it may not be required, but it certainly does not hurt. It is a rotary.
