One observation, looks like the car is burning up lot of gas during idle/slow speed. Idle rpm/speed is also seems to be higher then all previous cars/suvs I owned.

Awd A-Spec 1500 miles 21 mpg with 75% highway on midgrade 89 octane.
|
I'm averaging 24.5 mpg in comfort mode driving on mountainous roads in the Hudson Valley region of NY. I commute about 84 miles per day and drive about 70 mph on the highway. I have about 850 miles on the car so far and plan on trying Sport mode this week to see if there's a noticeable difference.

Ours is sitting at 21.3, most of that being a 1100 mile round trip to Orlando. 93 octane.
|
28.3 mpg on a 1000 mile round trip all on interstate with Top Tier Costco premium gasoline driving in comfort mode on flat terrain the whole way, driving at 72 mph most of the time. Light traffic so I could keep a steady speed not often having to wait behind trucks passing trucks and then accelerate which can eat up the gasoline a little quicker. I think this is as good as it gets for my vehicle at that speed, understanding that I could potentially get higher mpg if I were to drive at a slower speed.

Gtssenior-This is encouraging. Is yours SH-AWD or the FWD version? |

I took a long road trip (over 1,000 miles) on Nov 4 and 5; started back the other way today. For the following three fill-ups, I was on Interstates I-64 and I-95, most of the way: cruise set at 74 mph. 1st 2 tanks reflect 5% non-highway miles; 3rd tank covers 30% non-highway. FWD, Tech Pkg. -Tank 1: 432 miles on 93 octane, 15.7 gals = calculated 27.5 mpg. -Tank 2: 431 miles on 89 octane, 15.8 gals = 27.3 mpg. -Tank 3: 357 miles on 89 octane, 14.6 gals = 24.5 mpg. (I look forward to the next calculation, as this 3rd fill-jpg was ethanol-free gas from Wawa) On the first two fill-ups, I ran about 25 miles past the “0 Range” indication. With a 17.1 gallon-capacity tank, I was getting close at 15.8 gallons used. This tells me my copy of the RDX has the reserve to go only about 40-50 miles after “0 Range” is initially displayed. I won’t usually cut it as close as I did; the first time, I just forgot about how far it can be between stations in the swamps of SC (I-95 below Florence). The second time I was more comfortable: I knew that the range was available, and I knew where the next gas station was. My total mileage so far, since purchase in June, per Fuelly.com: 7,203 miles tracked; 72% hiway, 28% city; 25 fill-ups; 24.8 mpg overall. |

What MPG have you been getting on your 2019 RDX? Reports have been coming in much less than the sticker is showing. Please add your experience (MPG / driving mode/ and MPH, etc.) This could be a great fact finding thread. Thanks. I didn't read this whole thread, but fuelly is going to be better data than a thread like this. |
I have 1500 miles, and am around 19.5 mpg life to date, usually in sport mode, and I run 93 octane.

Nov. 2, 509 miles on the odometer 304.6 miles since the last fill 15.487 gallons to fill it up 19.67 MPG average I live in the Bay Area so it's a pretty good mix of city & freeway driving. I drive in comfort mode 99% of the time. The auto off on idle was sometimes on, but most of the time it was turned off. Trip, 258.8 miles 13.26 gallons to fill up 19.52 MPG average Really, no change since last time. |

I am up to over 5000 miles and resetting my trip meter after every thousand miles. The last two 1000 mile increments I have been near 50/50 split between highway and city on flat midwest roads and am only averaging 20.5 to 20.7 in comfort mode. So far this has been the biggest disappointment in an otherwise great car.

Yesterday I drove 90 mi from Monterey to San Carlos through the Bay Area end of rush hour traffic without stopping, hills and highway, the mileage upon arrival showed 27.4 mpg in Comfort mode. |

i don’t drive like a granny, but i stay close to the speed limit. A picture i didn’t show was 1/2 through my trip, before i started the fun part of the drive, i was averaging 29.7. Most of the drive was in comfort mode. I have noticed that comfort and sport are pretty close on rpm, but sport + raises the rpm by about 500. I used to drive a hybrid, so i tend to try to time lights, i coast some going downhill, but not so much that i lose speed. Sorry i can’t give more suggestions, i have been driving like this for at least 13 years and it just seems to be automatic. Billy

I now have 4300km and 11 fills for an average of 11.1L/100km (21.7 mpg US) with about half being highway miles. Just put on my winter tires so I expect a bit of a drop in efficiency.

SH-AWD - Tech. I am averaging between 20.1 and 20.8 with Premium gas from Costco. My driving is 90% city.

My driving habits were the same. On this tank I will try to not go over 75 (I go 80 whenever I can). Hopefully, that will make a big difference. |

Latest stats from Fuelly.com
https://cimg7.ibsrv.net/gimg/acurazi...0adbd488f.jpeg I record every fill-up on Fuelly; some folks only record a few. Here are the overall stats for the 2019 RDX (23 units in their database). |
My stats from Fuelly.com
https://cimg2.ibsrv.net/gimg/acurazi...838777088.jpeg here are stats on my 2019 FWD Tech, after 30 fill-ups. Overall Ave mpg is 25.0, with 24% city and 76% hwy driving. All the high “hilltops” are road trips; all the valleys and midpoints are normal, city/suburban driving. On the road I’m usually doing interstates at 70-75 mph. |

15.47 gallons to fill up 20.7 average mpg There was a slight improvement, but nothing to brag about. Trip since last fill-up: 286.6 Gallons to fill: 14.53 Average 19.72 MPG I drove mostly in comfort mode, like 99% of the time. I use idle stop when it does make sense, like driving down the strip with a lot of traffic lights. I tried to keep my top speed at 75, although there times I hit 80. I do live in the Bay Area, so the traffic here is pretty heavy and the commute to work involves a good amount of uphill driving. Going to work, maybe 2 out of 5 days, the traffic is pretty heavy and I have to drive 25-30 mph on the freeway with frequent slowing down. Going home is more downhill then uphill, but the traffic is worse, 3-4 days a week I'm driving 25-30 mph on the freeway with frequent slow-downs. Maybe 19-20 mpg is the best I can expect under these conditions? |

Have you considered early retirement? It would at least address the commute issue. ;) |

Yep, uphill and stop-and-go are both serious killers of MPG.

19mpg here . 1000 miles on car with Shell 91, at 5500 ft altitude. Drive down hill 1000 ft and up 1000 ft when “going into town and back”. Always comfort mode. |

Rdx
20.2 campared to crv 27 not so happy
|
After 13K miles, my MPG is up to 25.1
|
Mabey needs time to break in
|
After 7,000 miles, 20.7 mpg (US) cumulative, 24.8 mpg (Imp).
That's 11,000 km and 11.4 L/100km. |

On a flat highway at normal speed, say 8-10 over, I can get about 25-26. |

That's 11,000 km and 11.4 L/100km. The RDX isn't quite as much fun to drive as the TL but it's a lot easier to get in/out of for someone with bad knees. And the RDX is more practical cargo-wise ... |
A lot of 1st Gen RDX owners saw a mpg upward bump when they modded with Hondata/FlashPro, ETS intercooler, 1st Cat delete downpipe, larger exhaust, etc... My $300 08 RDX Hondata reflash paid for itself with the mpg bump and gas savings in a few years. Might see the same improvements once aftermarket starts up again with the 3rd Gen RDX?
|
I usually reset the trip computer with every fill-up and it varies quite a bit. Anywhere from 22 to 26 mpg, depending on how much local / around town driving I do during a given tankful.
For long stretches of strictly highway driving, I get between 30-31 mpg. That's probably my ideal max. |
I posted this in another MPG thread:
https://cimg0.ibsrv.net/gimg/acurazi...af1ba475e.jpeg That was my first really good trip from Chattanooga to the hills of North Georgia. Filled up when I left home and then about 40 miles from home on the way back. Billy |
