In my 2013 RDX AWD Tech, I pumped 87 (regular around here) gas in my first fillup. As I said, I'm not convinced from the discussions that going with Premium will really benefit me much. Seems the claims are that if you go with Premium you'll get a) maximum performance and b) best long term engine health. My 2008 Lexus IS 350, the car I had before this one and was traded in for this, said to put in premium only and that's what I did. This car says that Premium is "recommended."
I'm curious on what gas is in the car when it comes to you. Also, when you buy the car they do a fillup for you. I'm curious as to what gas is put in tduring that fillup too. I bought it with only 5 miles on the odometer so it wasn't much gas

Im about ready to fuel up the rdx for the first time, manual saids you should use 91 octane or higher. Anything under 91 octane can cause engine knocking sound and eventually failure. Im uncertain of that any thought's?

I honestly don't know... I know what the manual is saying, I know what the brochure said. But don't forget, all the Acura salesman nationwide are pushing that you don't need premium gas anymore. That was one of the first things mentioned to me when I was at the Acura dealer looking at the car. Same thing happened at Lexus when I was looking at the RX350. At the time of consideration, when I brought up what the brochure said, the salesman said it's something the brochure has to say.
I shared a thread earlier on acurazine where it was debated whether regular or premium had to be used. For me, the $5 savings per fill-up, multiplied weekly = $250 a year which I think is decent enough savings that without concrete proof, I'd rather err on the side of savings.
A lot of people in the thread say they didn't deal with any knocking so that point's off the table. The main things to consider are "full possible performance" and "long lasting engine health." Is it 100% true that one or both of these are possible with premium over regular? If so to what degree? I need that answered before I go to premium. The manual says don't go below 87. No problem, that I'll carry out.
Anywho, let's discuss further in that acurazine thread. Let's not take this forum too off topic.

Pretty sure there is no 'failure' expected with running octane below 91. I've been using 87 for most of 3000 miles so far and can't tell a lick of difference from the tanks of 93 I've used. 27+mpg on the 400+ mile trip, mostly 70+mph, finished tonight...all on 87.
There's quite a spirited discussion on the AcuraZine boards regarding this very subject.
I'm a believer that the quality of the fuel is one thing we need to watch. 'Top Tier' fuels contain more cleaners and protectants to keep the fuel system running properly. Fortunately, here in central Texas, Top Tier stations like Chevron and Shell are very competitive on price...often lower than the 'no-name' stations or Costco or grocery stores.
As I've often said, I would step up the octane rating if I were in the mountains, hauling something heavy OR running quarter-mile sprints on a regular basis.

manual saids you should use 91 octane or higher. Anything under 91 octane can cause engine knocking sound and eventually failure.
If the manual actually says that, why would you put in anything less? To save $200/yr, and risk a $10K engine?

One, the manual doesn't actually say that. Two, just got gas at my local Shell this morning with my truck and noticed that 91 octane was .50 cents more than 87 octane. If you drive a lot that could be a lot more than $200. Three, the engine in the RDX is the same engine that is in the Accord and Odyssey which both use regular. Just the tuning is slightly different so that you get more power with the higher octane. Similar to the turbo engines in the new Escape. Both octanes are fine but more power with higher octane.

Well.... that wasn't really my point..
If your manual says that, why would you even consider doing something differently?

Well, you're right if the manual says using a certain gasoline will harm your engine then it would be absolutely stupid to use said gasoline. However, like I pointed out to you, the manual does not say that. That is my point.
#1620 of 2244 Looking to buy 2013 RDX AWD w/ Tech
Dec 09, 2012 (7:17 pm)
I am looking to buy a 2013 RDX AWD w/ Tech. These posts have been really helpful. I went to the dealer today and here is the current breakdown:
Base Price: $36,965
ADAG (Advertising Fee?): $250
Total Invoice: $38,110
The holdback is 2% (about $800) so I'm thinking of offering $37,000 +tax/tag fees. What do you think? I'm willing to come up to $37,500 if they throw in some accessories.

depends somewhat on where you are. some areas are more competitive in pricing. But if you are around $2,500-3K under MSRP, you are getting a very strong deal.
