Car Forum / Honda Cars / July 2004'99 CR-V getting crappy mileage
Hi all, I have a '99 CR-V EX w/ real time 4WD that has - beginning a little over a year ago - begin getting fairly poor mileage compared to where the care was newer. I change the oil and filter regularly, have recently replaced the air filter, have installed (and properly gapped) new spark plugs, and recently had the wheels aligned. Still, I'm only getting about 19 - 20 MPG. Never mind that I drive on the freeway 90% of the time. I used to get about 23 - 25 MPG and for some reason, my mileage sucks now. :( Can anyone suggest what might be causing me to get such poor mileage? Thanks P.S. If it means anything, I have about 81,000 miles on this car. > Hi all, > [quoted text clipped - 10 lines] > > Thanks >Hi all, > [quoted text clipped - 8 lines] > >Can anyone suggest what might be causing me to get such poor mileage? 1. Check the tire pressure. This can seem trivial but makes a huge difference in handling/gas mileage. (assuming you didn't change tire size/type) 2. When is the last time you had the throttlebody, fuel injection, etc. cleaned? 3. Any codes on the engine or just a general decrease in performance? 4. When is the last time you had an alignment? If you are driving mostly on the freeway and it's out of alignment badly enough, it may (along with other things) decrease the performance as it's having to fight itself just to get down the highway. > Hi all, > [quoted text clipped - 10 lines] > > Thanks ================== It's not in the manual, but the valve adjustment on the CRV should be done at 50,000 or less, to prevent burning valves, but you problem is more likely the PCV. Your Dual Pump Fluid should also be changed after the first 30,000 miles (it's also not mentioned in the manual. try hondasuv.com for further confirmation. A valve adjustment can add a couple miles per gallon. I have a 2001 CRV and around town the typical mileage was 18-19 and 23-24 on the freeway. It has 38,000 miles on it now, but I had the valves adjusted at 33,000 miles and the mileage jumped to 20-21 in town and 25-26 on the freeway. > > Hi all, > > [quoted text clipped - 21 lines] > > try hondasuv.com for further confirmation. Thanks to you, DragonRider, motsco, and cosmin for the advice. It is much appreciated. I will start with replacing the PCV and then see about having the valves adjusted. Thanks again. > A valve adjustment can add a couple miles per gallon. I have a 2001 CRV and > around town the typical mileage was 18-19 and 23-24 on the freeway.
