89 gas on rdx?
Hey guys,
I have been using 91 gas all the same until today. My wife accidentally put 89 gas to our car by mistake today. What will happen to my engine? I assume it shouldn't be a big problem just for one tank of 89. Any thoughts?

one tank shouldnt be a problem.
The higher the octane number, the more compression the fuel can withstand before detonating. In broad terms, fuels with a higher octane rating are used in high-compression engines that generally have higher performance. Use of gasoline with less octane numbers may lead to the problem of engine knocking
Just be sure to refill with premium next go around

I don't want to start the regular vs. premium discussion all over. However, I have used mid-grade fuel for the entire 5500 miles I have driven my RDX. Never heard a knock or a ping and I am confident the engine management unit can compensate. Car has great power and I get ~22.5 in pure city and 30 to 32+ on long highway trips. Base FWD.

You can run it on 87. The dealer said to get the best fuel economy and most horsepower he recommends premium but Premium is not required. Personally, I put in Premium, but you probably wont even notice the difference in performance because it is so minimal (maybe 5-10 HP, 1 MPG less).
