Yes just follow it, we get about 6k miles out of it w/mixed driving between oil changes. Be prepared to pay $90+ for oil change.

My wife is unable to lock the doors of her 2006 RDX with the key fob. Any hints?
#2727 of 2736 91 octane gasoline
Nov 13, 2010 (1:30 pm)
I own a 2011 RDX. The manual says to use 91 or higher gas, and I fully intend to do so. My question is, if I accidentally fill it with 87 and drive it, will I do any damage to the car? I asked two dealers and they seem to have opposite opinions.

I'm sure the ECU will retard spark timing to compensate and prevent knocking, but the engine would be running out of its ideal tune for that whole tank.
Even if you had to use regular, because that's the only gas available, I'd only put enough to reach another gas station that had premium.
Turbos increase the effective compression ratio so they are far more vulnerable to knock.

There is "spark" knock, which can often be compensated for via timing change, and there is compression/dieseling/detonation knock.
The latter is compensated for via the use of EFI to enrich the mixture.

If so, mileage would drop and defeat the purpose of using lower-cost fuel in the first place....
Stick with premium.

So it sounds like 87 octane does no harm to the engine, if it was used a few times by mistake. Do I interpret it correctly?

"..mileage will drop.."
Not necessarily, it depends both on the price differential and the driving style. Price issue is obvious and if the driver doesn't go WOT very often the A/F mixture need never be enriched. And we can forget about detonation due to (uphill, towing)engine lugging with an automatic.
When we picked up our '01 Porsche at the factory we were told that fueling with regular would do no harm.

Anybody use 17' rime for 2014 RDX (the OE rim is 18')? Will it work properly?
