    improving '06 CRV MPG results???

    Hello out there,
    I recently purchased a 2006 CRV SE AWD 5AT to accompany my 2004 CRV LX. (which the girlfriend drives)

    I purchased this used with 69,000 miles and it is certified. I run mostly highway miles and, after racking up about 1500 miles, have added the #2429 K&N air filter. (I had an extra one lying around.) Through certification the V has had the trans. and differential fluids changed out and everything else is up to date for maintenance.

    I am only able to get 21 to 23 MPG so far. This is both with the Honda air filter and the K&N filter. I believe that this V is, in the best conditions,
    suppose to achieve 28 MPG as a top rating. Does anyone out there have any suggestions as to how I can improve the MPG's? I know that this is winter time but being that this V is used and I don't have a maintenance record of the previous owner, can I do anything further to help improve the results? Again I am placing mostly highway miles on this CRV and I feel I am not achieving a good enough MPG. I realistically think that 25 to 26 for winter highway driving should be average. (Maybe I am dreaming though)

    Should I be using 87 octane from Shell or BP Amoco instead of the average gas station?

    Thanks for your assistance.

    I found with my 06 that keeping the RPM around the 2200 mark helps big time.To me that means 110 to 118 kph or under 70 mph.On one trip to Niagara Casino I ran 120 to 140 kph there and back and used 3 quarters of a tank.The next time I kept her under 120 kph there and back and only used a half tank.

    Not really a whole lot you can do other than driving cautiosly. I think the best I ever got was 25mpg and that was with everything completely stock and riding the cruise control at 65-70 on the highway. I can tell you to avoid adding anything that would add considerable weight or drag to your V - like a roof rack or side steps, etc. Also, you'll want to stick with stock sized touring tires. I think you will see slight improvement with warmer weather, but I'm not sure you'll get up to 28

    remove your heavy spare wheel, as that saves me 1-2 MPG! In its place, just buy a tube of puncture repair fluid.

    So your saying that by removing about 50lbs (about 1.5%) of the vehciles weight, you can improve fuel economy by 5-10%???

    EPA estimates are done at around 50mph so try driving that fast and see how your mileage improves. I know that when my wife drives (70+) we see 23 mpg but when I drive 62-65 we get closer to 26. Speed matters...as does the weather!

    Thanks for the replies.

    I'll just have to see what happens when the weather gets warmer. I usually drive on the highway around 60-65 mph. 65 is the posted speed limit here.

    Does anyone feel that using a Shell or BP Branded gasoline is better for the engine, or are their claims of better engine performance just some hype?

    Thanks again for your comments.

    I try and use Shell gas because I feel that my V runs better.No specifics,just how I feel.

    IMO, several factors could be responsible.

    1.] What is the air pressure in your tires? You could have under-inflated tires. Try measuring when cold, usually in the AM before you leave for work. If you last measured in the fall, cold weather will lower tire air pressure, just as warm weather will increase tire air pressure. Many readers have found that keeping tire air pressure between 32 - 36 psi offers the best compromise between comfort, road noise, & fuel efficiency.

    2.] Eye-foot coordination, i.e., as fast as your tach goes from 0 to 3K+, so does your fuel gauge go from F to E.

    3.] At your next oil change, switch to synthetic motor oil.

    Around town, my wife averages about 22/23 mpg [about 50-50 hyw/stop-go] with aggressive starts. On long road trips @ 70, I average about 28/29. Check out this thread: 2009 road trip mg.

    I've owned my '06 since new and I've never got anything more than about 25 or 26 on the highway, and 21 - 23 around town is about tops. I drive conservatively and keep the air pressures up. If you have the roof bars they may add a little drag. Me, I wouldn't worry about a few mpg and especially wouldn't spend any real money to try to improve it. As for gasoline, I've researched and written on the topic on my motorcycling website (applies equally to cars):
