Looking into leasing 2008 RDX. Wil the turbo engine accept 87 octane gas? Or do I really need to feed it 91? Considering Infiniti FX35 as alternative.

Replying to: mfeirman (Jun 17, 2008 6:24 am) Apparently even in Denver where the air is so much thinner and therefore the use of premium fuel is more important for keeping the engine HP/torque up to "snuff". If the ECU cannot abate knock/ping via increasing the A/F ratio it will command a downshift more often. |

Replying to: ptd1 (Jun 17, 2008 6:45 am) The primary difference at 6500 ft (Denver, 6500 ft...??) is that even at WOT the cylinder will NEVER get a full "charge", a full fill of A/F mixture, therefore almost never encounter engine knock/ping due to low octane, even in a relatively high compression engine. But at higher elevations it is even more important to match premium fuel with a high compression engine in order to keep the engine performance, HP/torque, within "reason" and thereby avoid the continuous downshifts that results. But other than the "nuisense" of the too often downshifts there will be no adverse results. |

Replying to: wwest (May 31, 2008 9:21 am) The 5 speed transmission is also not that smooth as I had wished. But otherwise its a good car and handles very well.

Replying to: suvsearcher1 (Jun 18, 2008 7:42 am) If I come over a rise in the highway and just tap the brake to release the cruise, it downshifts... and other times too (approaching a curve when I decell... very annoying... bad for fuel economy, and can't do much for the life of the trans either. Acura has no tweak at this time.
