Coupes & Convertibles Mazda RX-8 Mazda RX-8 Gas Mileage Reports

You are in the Mazda RX-8 Forum. Your Host is claires
Would I be harming the RX8 engine if I used regular 87 octane gas? Also would that effect my gas mileage negatively?

I could never justify buying such a small car, that isn't as fast as the competition that gets such lousy gas mileage. The 350Z gets about 25 MPG. Even the Mustang GT gets better mileage and it is a V8! I owned a 1973 Mazda RX2. Fast little bugger, but it had oil burning problems. I wish they could work out the kinks in the Rotary engine. Seems like they haven't yet.

Replying to: carfanatic007 (May 10, 2006 10:31 pm) The following are the points to the rotary engine design: 1) Simple design engine design with few moving parts raises overall reliability over time. A design life of 200K miles on the old rotary designs, a sports car engine, was unheard of in the complicated multi-value piston world of the past. The Renesis Rotary's design life is 500K miles. Racing a rotary engines means one re-build per season, where as racing a piston engines means re-builds after every race. 2) Much lower torque at low RPMs is a wear and tear saver on the entire drivetrain. 3) The drag racing mentality of torque heavy engine design, based on a NASCAR formula in the USA is just dumb. Go watch any VOD Car video as torque heavy monster cars drag off screeching burn tires, only to crash half a block down the road as they simply loose control of the poorly torque balanced car. 4) Engine weight and size eliminate frontend steer compared to the high center of gravity weight of any piston designed engines. Acions might go to the flat four and flat six piston designs of Porche and Subaru. |

Replying to: KarenS (Jun 02, 2005 10:38 am) 17 around town 23 highway 11 track My worst "around town" mpg was 15, but that was mostly due to a heavy foot and high revs.  Why do people b*tch about the mileage? This is a sports car, not an econ-o-box. Our mileage is similar to other comparable sports cars.

Replying to: paul_in_dc (May 12, 2006 4:39 am) It is not a true sports car. RX-7 was a sports car. I like RX-8 but couldn't get over its poor MPG issue. Mazda has this engine for at least 10 years but yet they still couldn't improve its fuel consumption and motor oil issue. My IS250 can go 400 miles(75% freeway) per tank at 29/30+ MPG. Expect more from your sporty car.
