I'm in the market for a 2006 or 2007 RL (I Live in New England if you have one) and will be doing 95+% highway miles. What is everyone else getting for average milage on their RL? I know it's rated for 26 but as they say "your milage may vary".

P.S. this will be replacing my 2000 TL with 266k miles. What a great car this was.

With 100% hwy, 28+ is achievable. You should be able to pull 25-26 with 95%. However, it only takes a few stop lights or one traffic jam to knock that down fast.

The RL cruises great. However, it is weighs over 2 tons so getting it moving takes a lot of energy.

I'm with the christmas dog... my guess would be average 24-26 but on a good highway trip the upper 20's is possible but the first take off from a dead stop and you are back to 22-24

Best I was able to get with very disciplined driving, 55-65 mph, from south west Virginia to South Carolina, so slightly downhill (Piedmont, you know), was 29.8 on PAX tires. The car was loaded to the gills. Ever since putting on performance tires, the mileage has gone down, 26-27 mpg max, but have never had such an opportunity as that long trip with disciplined driving...

My average is a solid 20-21 in combination, but when I drive to Vermont from SE MA, once I get to 89 I can get the # up to 27-29...that is, when the car is working.

Solid 28, up to 30 (downhill with the wind) highway but only 18 or so around town.

I've gotten 28.8 mpg on a 660 mile trip to Atlanta from Virginia.

The trick is to feather the accelerator. I always would NOT accelerate on up hills (instead, keep a steady speed, whatever that speed was, 65-70) and just KEEP IT THERE the entire time while going up a hill. While going DOWN a hill, I'd let it COAST a lot, so I wouldn't really go much much faster than 73-74. If gravity took it, I let it go but I wouldn't accelerate down a hill.

With that method, you can get 28.8.
Hit that first traffic jam and your MPG is toast though. It'll be at 25-26 before you know it LOL

I've had the car for a few days now and have made 3 trips back and forth from work which is 2 miles to get to the highway....go 38 miles on the highway...then the last mile to work is off the highway.

With that in mind, here is the strange thing. I get 29.x miles on the way in to work, but only around 24 on the way home so I have averaged around 26. Hills on the way back must bee steeper

26 mpg at a steady 75 mph on level ground, accelerating and decelerating only with the steering wheel cruise control buttons.

seems normal

Wind can affect you too. If it consistently blows one way most of the time, that could be your cause.

a big meal could too

2008 RL - just did trip up 95 from MD to MA. 500 mile 7.5 hours ~24 MPG with new DWS's. fast accels from stop lights to 89 MPH on 95. My normal MPG at home is ~21, Like my fast accels ;-) you'll love the car good luck

took my 05' 1500 miles on a road trip up north to go boardin this last week. My average for the entire trip was 28.3! def wasn't grandpa'in it (paddle shifters activated )...just had a fresh flush of redline D4 transfluid and about 1000 lbs of men and beer in the car. not to mention about 400 of the miles were high-rev downshifts on a snowy mountain.

I've never gotten these numbers..even downwind in a hurricane. So i'm gonna comp the mileage to winter fuel and the recent switch to 0w20 full synthetic (stuff acura recommends in the new cars)

RevHappy

Uh, winter gas blend actually saps mileage, not the other way around.

myronf

I have seen 30-31 mpg in cruise at 70 mph for multi 100 mile trips. 18-22 around town. All on mid grade gas.

phishfood

I'll repeat exactly what all others have said.

29-30 if you are so disciplined all you do the entire trip is concentrate on max MPG. I find the roll downhill and no acceleration uphill ... even allowing yourself to slightly lose speed uphill to avoid a downshift helps immensely . If you're familiar enough where you know a big hill and can time cruise bumps down with steering wheel so you're going 5MPH slower at top of hill will help a lot.

28-29 if you're very careful

27-28 if you take care, won't require lots of effort

Normal drive with a few burts o speed, little tailgate mixed in, etc. type stuff and you're 25-27

phishfood

Also a little bump in tire pressure can help. I normally do 2-3 PSI over rec day to day, but if I know ill be doing 100% highway on a long trip I might fill up to 5-6 PSI over for the trip.

TonyCD

I don't know if I call BS, but I call "miracle" at the least.

Also, to echo a discussion from past threads, using anything less than premium gas in this car is NOT encouraged. Most cars that call for premium can burn lower grades with no damage and only mildly degraded performance. The RL is not one of them. For the health of your engine and emission system, you should use the recommended grade of gas at all times.

oo7spy

"mid-grade" varies state to state. In LA, 91 octane is in the middle. In TX, 89 is in the middle. The RL is tuned for 91.
