Filled up yesterday and got my best mileage so far. Around 1,800 miles on the car now (6mt) and got about 16.25 mpg. This is the best I have gotten for just commuting. Could be the cold weather, could be the mileage is getting better with more miles on the car. Could also be the pump shut off too soon - but I filled up at the same station and the same pump (the one I know has the working lock) as I always do. in the event this was the case, then next time I should see worse than normal mileage.

Replying to: dwynne (Nov 18, 2005 10:19 pm) After 3500 miles with my RX-8 AT using full auto, no paddle shifting, no fast take offs, and staying under the speed limit, I pulled 17mpg. Full auto constantly shifts to the minimum speeds for 2nd, 3rd and 4th and drops rpm to 1500 or less for maximizing coasting. You end up riding the brake a lot more since there is little engine breaking available in 2nd, 3rd and 4th at low rpm levels. But driving like that all the time would be a horrible waste of the RX-8 resources and probably would cause carbon build up in the engine systems along with extra brake wear. Driving with paddle shifting between 2500 and 4000 rpm strictly, I get 15mpg. This is the best balance of enjoying the RX-8 resources and traffic reality during the day. Driving with paddle shifting between 4000 and 6000 rpm strictly I get 11 mpg.  This is hard to do on a practical level in the city. Late nights is the only possible time and even then traffic can get in the way.

2004 RX-8 33500 miles bought new Nov 2005 for a real good price. Worst mileage 14.8 Georgia mountain autocross Best 22.8 hwy - 74 mph (wife driving) Daily driving 16-17 45 mile round trip commute. Drive easy 17.7 maybe, Drive hard 16.0 - I pick drive hard... BTW first set of tires lasted 30K now have Dunlops - much quieter, better ride, slightly better mileage. |

Would I be harming the RX8 engine if I used regular 87 octane gas? Also would that effect my gas mileage negatively?
