the RDX takes premium, which is 91 in canada

there has been many discussions on this, manual says recommends premium (91), gas tank says premium only....however some feel they can get away with running mid-grade (89) but it seems they do see a mpg hit with that. Personally only 91+ for me

I could have went with a Honda Pilot which takes regular but since I decided to go with the higher Acura vehicle, I will give it the premium it deserves. Personally I dont think its worth it saving a few cents or dollars short term and potentially risking your vehicles performance/reliability/whatever in the long term.

In states with mid-grade at 89 and premium at 93....... I guess you could alternate fill up's at the half way point....... and have about 91 octane in your tank. I just go with the premium!

is there 93 in Vancouver? I went to shell yesterday, just saw 87 and 91

i think chevron has 92 and husky has 94...i always go to esso, they only have 91

My dealer in California advised me that regular, 87, is the same as premium in the other 49 states, becaue of the additives. So far my RDX is running very nice with it.

what?!? no way...can anyone else verify that? cause if so that's like nearly $.50 a gallon here difference.

when i used off all the gas in my tank(91 right now), can i changed to 93? Or I have to "wash" my tank before i can fill 93?

number84

no need...just fill it up as usual...no need to "wash" the tank....btw, where did you find 93 in vancouver? and why are you filling with 93 if 91 is enough? just curious...

laputa

no, i dont know where to find 93, but i think you can get 92 and 94 in CHEVRON. Just my dealer told me I should use 93. My friend told me 94 is better for a turbo engine.

Ha, sounds like a load of BS to me. I'm not an expert, but additives might keep the engine clean, but they have no impact on octane levels, which affects what temperatures the gas combusts and ignites at. If I were you, I would go premium...not worth the $0.20/gal to chance it.

keep in mind this vehicle is turbo 91 ftw

i only use premium (90% of the time 93 octane). i get great mileage & average 21 mpg with mix driving. easily achieve 24 mpg on highway (after 6000 miles). anyhow, don't use anything less than 91 (despite what some would say). think about it, one extra mile per gallon saves about one gallon of gas per tank. that pays for the price difference & takes care of your engine & provides outstanding performance.

definitely agree considering its a turbo 4

Premium gas will not increase gas mileage. Your MPG is all dependent on how aggressive you are with the right foot/lead foot. Using mid grade gas will work fine in any car (turbo or NA) for normal driving, however it will obviously decrease performance and will not extract all the ponies out of the engine. If you are stomping on the gas at every red light you will want 91 or higher to prevent the possible pinging noise.

I would agree to a certain extent, that under normal driving conditions, like city driving, and not being heavy lead footed... you might get away with engine reliability issues...

But once you start putting substantial load on the turbo, knock/ping issues will come up, if not immediately, maybe through the years of operating the vehicle.

From my experience driving SAAB turbocharged cars in the past 5 years, I really don't recommend cheaping out on a few cents per gallon of gas to go with 89 octane. Go with the car manufacturer recommendations, and use 87 or 89 only if you don't have a choice, and stay with premium as much as possible. I mean, you bought the RDX not because of it's SH-AWD only, but because of what the whole package presented to you... a upscale, high performance luxury CUV. So if you can afford to buy it, which is considerably more expensive than other korean or japanese makes (like Mazda, nissan, Honda), then why stinge on the few cents?

When you chose to own a turbocharged engine like that in the RDX, you must have wanted the extra performance, then why are you now cheaping out on not providing the right octane to enjoy that performance potential?

Amazing that people will spend +$30K on a car and then cheap out on gas! At the most you are looking at an extra buck or two per fill up with premium and as someone else mentioned, the extra mpg or two that you get with premium will end up washing out the cost difference in the end. If you were so concerned about what you pay at the pump and your mpg ratings, you should've gotten a hybrid or golf cart for your commutes.
