#12 of 15 Re: Horrible mileage [badbuy] by nebraskaguy Jan 23, 2009 (4:08 pm)
Replying to: badbuy (Jan 22, 2009 11:23 pm) I have an 05 RL. Last spring I drove 8,200 miles on one trip and consistently got 28-30 mpg - often at 70+ mph. Over Christmas, I drove 4,100 miles and got around 24-26, possibly because of the colder weather. One thing I noticed on my last trip - I got consistently better mileage using Shell V-power, usually about 2 mpg more. I want to experiment more with this to see if it was an anomaly. I usually use Sunoco, but plan to use Shell V-power for a while to see how it does.   My city driving is a different story, however. I quite often get in the 14-16 mpg range. I attribute part of that to relatively short trips - 2-4 miles is standard for me.

Replying to: badbuy (Jan 22, 2009 11:23 pm) I have a 06 RL and I never heard of that TSB# you are talking about!!! I get my service done at the Acura dealership and no one said anything about that!! I work 42 miles from home round trip 84 miles and I get around 24-25 mpg mostly highway... I love the car it just doesn't have alot of power!!

Replying to: tamparl (Jan 23, 2009 3:34 pm) Sorry for the confusion on timing. The TSB is 07-003 which mandates (for ALL 2005-2006 RLs and certain Vin # 2007s) a replacement for the fuel pump modulator which has a recalibrated fuel pump. This was to fix the lag problem that showed up (I guess in 2007 when the TSB was issued) in very hot climates and/or at high altitudes.   I'm not condemning all RL owners or future owners. I'm condemning a car company....American Honda Motor Company....which doesn't give a dxxm to do anything about this. They put it on the computer and say it's OK rather than deal with the real world. In fact, they did not even have the courtesy to reply to any letters on various problems.   For a car to have such erratic behavior in MPG, there has to be something wrong. And for the Long Trip mileage to tumble after the TSB fix, there certainly is a problem.   In decades of buying new cars including products from: Chrysler, Nissan, Toyota, GM , and Ford, I've never had this deafening silence. "It's truly luxury living with ghetto management".   There should never be an exception for horrible customer service...especially if you're attempting to produce a "luxury car line".

Replying to: jensad (Jan 23, 2009 11:11 am) I have a new 09 RL, about 900 miles and get 20-21 mpg if I threat the accelerator like a raw egg. I get about 23 miles on the freeway with almost no traffic at 80mph I certainly hope this will improve.
