Hi, new to the RDX forum. Thinking of buying a 2013 but interested in what owners who have logged several tank fulls of gas, trips etc. are seeing on MPG?
I have a 2011 TSX and pleasantly surprised with consitent 36 mpg on trips. overall light highway and local 26+ mpg. It was rated 31 MPG on highway, so hoping the 28 MPG figure on the 2013 RDX might also be low vs. reality???
Anyone have some info on this?
Also, if using Reg. or Premium fuel. I did notice a 2 mpg increase on the TSX using premium vs. reg. just wondering if same can be said of RDX?
Thanks all for any feedback .
Next is what color.....thinking white, but my wife will decide that one.

Hey raviola4,

I drove my 1 day old RDX from San Diego to LA and was able to get 28.5.

raviola4

Thanks to the quick responses. Interesting to see some of the MPG posted to other sites. I know my 2011 TSX doing alot better than early days, so hoping for all it improves somewhat over time. Obviously with this summer A/C runs constantly. Still need to test drive and with wife etc. But from what i've read, overall a decent driving experience and we do miss our SUV. Had an 06 Rav4. Will most likely trade her car in after the summer on an RDX. I realize $38,000 for a car should squabble about MPG, but hey, don't want a gas hog either. If i can squeeze out 30+ on a trip, i'd be happy. Again, looking ahead to retirement in 2013.
thanks again.

Lanman

I would think that 30 MPG would be possible if you drive like you are retired.

FYI - Congrats on the 2013 retirement, I am very jealous.

Raviola...I am getting about 30 mpg (7.9l/100km) without too much difficulty and this is driving about 60/40 (highway/city) but even the city is not crazy urban city but enough that there are street lights and frequent stop and go, but not bumper to bumper idling for 1h in some cities. Even at the stop lights, I usually don't have a very aggressive start, that is usually kept for my TL (lol)

raviola4

Good to see decent mpg . Also seeing more pics of white RDX, which I'm leaning towards . Probably looking to buy in Sept.

You my friend have great taste in vehicle and colors Good thing you don't live in my town as I'd hate to have to have someone to compete as I try and pick up women given we have the same taste (lol)

Colorado Guy AF Ret.

Mine is still "breaking in" but, my last fill up I got 24.2 mpg! Now, that was figured by the old fashioned way...doing the math!! The computer was close though. Now, that was a tank that was all in city driving, with the air cond. on virtually all the time. That amazed me! I had been getting in the 23 mpg range in town. Now it's moving up a little. I have no doubt it would get 30 mpg or a little more on a trip.

Is this a great SUV or what??? LOL!! No regrets on this buy...no problems, no issues...just results. Where is some wood?? LOL!!

mwachel

Highway I can get 29. Mixed is about 23 or so.

backwoody

On a couple of 250-300 mile round trips to mountain locations in central Idaho, my new RDX delivered 32-33 mpg. All highway driving, over two mtn passes each way, at speeds varying from 50-65.

Better than I expected. Tire inflation will have an impact - as well as driving style and average speed.

MGP999

I am lucky if I can get 21-22 mpg during mixed driving, long highway trips have been a bit over 28 mpg, a bit disappointing regarding the former.

wizardjjr

What pressure do you have your tires at?

tires38

Driving San Francisco to Los Angeles and back including some city driving averaged 24 mpg - hwy speeds around 75 mph .. bit on low side compared to some feedback here

hawkeye62

I just checked my "B" trip computer. It has 1488.9 miles, 38 mpg average speed and 26.4 mpg. This data includes a 933 mile highway trip where I got 29.8 mpg.

My "A" trip computer is set to reset data every time I fill the tank. I usually get about 22 mpg on a tank with in town driving.

Just hit 450 miles on a new AWD and the first legit tank filled with mid grade gas: 24.93 for sure. 100% around town with a few miles on the local Garden State Parkway here in NJ up to 90MPH to make sure all wheels balanced properly. So my best estimate is around 24-25 around town and easily in the mid 30's on a highway trip. Next few tanks I'll move to Hess regular which is what my Acura guy told me to burn with no worries and see how the mileage is affected. Interestingly a close friend has a 13 Mustang GT and he just did a 3000 mile trip. NO DIFFERENCE in mileage between high test and regular-cruising at 75 to 80. If he wants the full 425HP he can burn high test or live very happily with 390HP on regular. I'm guessing these 6's go down to about 250HP on regular which is plenty of power for a small vehicle. The accords run regular with these 6 cyl engines with a very close HP rating.

On the highway at 70mph w/AC on low I get 30-31mpg. AWD non-tech.

I use 87 octane.

This is with the real world calculation of filling it up and using a hand-held calc to determine mileage. I think the computer is just a good guesstimate.

I like to be precise.

backwoody

36 psi. I added a couple pounds above delivery recommendation.

jonmarcieRDX

Have had my wifes new RDX for about 2 weeks now. The mpg says 24.9 on roughly 60% city, 40% highway. I plan on doing the old fashioned math on the next fill up.

smarty666

Just curious, but has anyone tried putting regular in the RDX? There is only a 10 cent different between Premium and midgrade so I'm eliminated mid-grade, but there is over a 40 cent difference right now between Premium and Regular which starts to add up.

Just curious as to what everyone else is doing. I know the owner's manual says premium recommended for maximum performance, but I don't want to put regular in if my mpgs are going to drop!

aks1972

I have been putting Chevron premium from day one and mileage is fine. I have not and will not put regular if there is no performance drop. On an average I consume roughly 10 gal per week. At $0.40 difference it is $4.00 per week. I am not going to lose any sleep over that sum.

weather

smarty666....I agree with ASK1972 100%. For us, the difference between supreme and regular fuel here in Canada (where I live) is 6 cents a litre. So if I put 50 litres (because I will never let my tank go dry), 50 X 0.06 = 3.00$ a tank. If I fill up 4 times a months, that means 12$ a month.

I have said this many many times before, the difference between supreme and regular is NEVER the big factor when trying to save money at the pump....the vehicle you drive does.

aks1972

Thanks for the confidence vote weather!!

I'd like to add that we (all of us) can save more money by judicial use of our vehicles than arguing about regular v/s premium.

---Drive if necessary, combine multiple errands in one trip, maintain optimal tire pressure, judicial use of a/c etc......

smarty666

What are people getting for avgs per tank that do about 80% highway driving and 20% rural/suburban city driving?

smarty666

That's a bit disappointing as I was expecting to do about 25-26mpg avgs per tank with mostly highway driving.

geocord

Most V6 midsize sedans only avg 25-26 mpg. That would be asking a lot of a CUV to match.

smarty666

Not when your suppose to be the highest mpg in the class. I don't think thats unreasonable with a 19/27 and 20/28 mpg rating. Thats the rating on most mid-size sedans, as you pointed out.

aks1972

Whenever I have driven highways only i.e. decent speed and free flowing traffic, I have gotten 30-31 easily.

I have not done super long trips, mostly 60 -70 miles one way and the mileage estimate is based on the car indicator. I find the indicator to be accurate within 1/2 a mile per gallon. It matches my calculations using the old method: miles driven between fill ups and quantity filled. I keep my filling ritual same i.e fill up early in the morning, using the lower speed setting for the nozzle and not topping off after it clicks. I fill at the same gas station all the time.
I have to tell you that I like to drive sensibly i.e. no sudden acceleration or braking and speed between 60 - 70 mph.

I dont think there are any other CUV's out there with this combination of price, features, driving comfort, power as well as the fuel economy.

smsazucar

Just got back from a 760 mile road trip from KS - MO - IA and back. Going 60-65 mph = 29-30 mpg, 70-75 mph = 28-29. Overall we got 27.8mpg on our road trip. That was about 80% highway & 20% city and gravel roads. I'm super happy with the gas mileage, my old SUV got at best 17 so 27.8 is great.

I've had my RDX about a month, 1500 miles total so far and for the first 1500 miles I've got an average of 26.7 mpg. I'm probably 60/40 highway city driving.

Hope this helps anyone looking for real-world mpg info.

geocord

No, most of the current V6 midsize models are rated a lot higher than 20-28. The new Accord V6 is rated at 21-34 for example and it's combined is 25mpg. Keep in mind we are talking about a CUV here and not a car. No SUV or CUV can match a car in aerodynamics. It's just physics. The RDX is EPA rated at a combined of 23 for the FWD and 22 for the AWD. To expect much more than than 23-24 combined for an AWD because of your heavy hwy % would still be wishful thinking and expecting more than the Acura promises.

BlackDogRDX

The RDX definitely does benefit from cylinder deactivation so if your highway driving is totally traffic free you probably will see around 30 MPG. The minute you need the 4th-6th cylinders the numbers will bounce down to 24-26. Out here on Long Island I've never gotten a tank average over 25 MPG and even taking a ride down to DC from here on I-95 I only got around 27 because there was some traffic.

Bottom line is if you have a heavy foot and are driving in traffic every non-hybrid vehicle will return less efficiency than in true highway conditions.

Sculldog3

I'm the flip of many, with city / highway split more like 80/20. Also have a heavy foot. Finally got around to resetting the Trip B to measure on each new tank, and it's been 19-21 for mostly pure city. For the highway stuff I've done, it does seem to peg in the mid/high 20's, particularly if it's not too hilly and you keep the speed down. Seeing 30's on the meter only when coasting and foot of the gas. Basically, even light pressure on the pedal on the highway seems to drop it out of cylinder deactivation mode and back into the high 20's. Still an improvement over the previous car, and if I wanted the higher mileage, would have gone with the CR-V and the 4. The drivetrain is just so smooth and instant on, that it's hard not dip into it where ever and whenever. Also find the exhaust note to be nice when you get it downshifting a bit on the highway!! Enjoy it while we can and while gas is still available and reasonably affordable!

aks1972

In the situation i described above, the mileage was achieved with cruise control set between 60-70.

robuckj

Over the long term I normally run 70% highway/30% city, but for the 3 months this summer that I've had the RDX I've been more like 63/37 (according to what I've entered into Fuelly). I'm averaging 24.6 overall, and my Fuelly chart line shows it's been mainly between 22 and 24 MPG since July.

On a 1,500 mile Interstate run in late June, I got 28 to 32 MPG (by Fuelly's calculation, which is the same as using a calculator). I'm happy with that, especially since I wasn't trying very hard (I did around 70 MPH average, with A/C on).

I'm also surprised that my Trip Computer is showing the same as Fuelly's 24.6 MPG overall for the 4,500 miles I've put on the vehicle since new. That's more accurate than the TC in my old MDX.

smarty666

I don't care whether its a sedan, CUV, or SUV. The EPA numbers are the EPA numbers. When your touting best in class mpg with highway numbers of 27-28 mpg, then when you have someone heavily toward the highway end of the driving spectrum then it should be above the avg. Getting 22-23 mpg in this vehicle is nothing to write home about. There are plenty of other CUVs getting that for avgs, the Lexus RX350 and Q5 for example. There's no reason, with more highway miles this car getting 25 mpg avgs easy. If the RDX can't do better than that, than Acura didn't really do good to let it stand out among the competition with mpg.

geocord

Like i said, if you have an AWD and get 23-24mpg avg(which is two more than the EPA combined rating) I think you will be doing pretty good. Depends somewhat on how the 20% city driving is and how harsh those driving conditions may be. Maybe you'll get better, hell I don't know, but you make it sound like they are false advertising or something. I think most people would be very happy driving one of these AWD CUVs and getting 24mpg when a similarly powered FWD sedan would probably only get about 2 mpg better. My current V6 suv (same size but heavier) gets about 16-17mpg avg so I'm looking forward to get 23mpg. Good luck though.

aks1972

I don't understand. When quite a few of us are getting even better than EPA numbers, where is the problem?

When I commute to work 20 miles each way, my economy is barely 22. I commute on the highway (101 in Northern California), but I am driving at or below 30 mph throughout in stop and go traffic. I should be suing Acura and EPA for misreprenting the numbers? After all they claim 28 for highways!
