Car Forum / Honda Cars / June 200798 Accord LX Fuel Consumption Issue
Last month I replaced 1. Air filter 2. Spark plugs 3. Wires 4. Distributor cap 5. Distributor 6. Both O2 sensors (because check engine light was coming) Items # 2 to 5 were bought from Honda dealer. Also, it has new tires (about 8,000 miles), along with items listed above, I have the tires rotated and air presure checked. After all these repairs, 98 Accord LX (116,000 miles) is giving me about 23.3 miles/gallon, up from 21.5 miles/gallon before reapairs. About 3.5 years (@ 77,000) ago, its transmission broke down and Honda replaced it for free. I have done most of the service with Honda dealer. Is 23.3 miles/gallon OK for my Accord ? I am expecting little more, about 25.7 miles / gallon. What do you guys say ? Usman > Last month I replaced > [quoted text clipped - 21 lines] > > Usman Is it a 4 or a 6? For a six, it sounds fine. The 4 cyl accord usually does a bit better... Clean the PCV valve next, using carburetor (PCV) cleaner. Or if it seems very dirty, consider replacing it. It should cost not more than about $20. I would say it's about due. Top off the radiator coolant in the reservoir (per the owner's manual's directions) and watch the level for a few days until it's steady and per the manual's specification. At what pressure are your tires maintained? Possibly consider having the valve timing checked. fueleconomy.gov can give you an idea if the mileage you're getting is reasonable. Your numbers certainly seem well in the ball park. For fun, please state the exact model of Accord you have: manual or auto transmission and engine size in liters. Also, what kind of driving do you mostly do, city or highway or somewhere in-between? Elle A 1000 mile road trip in my 1991 Honda Civic LX (manual transmission, no a/c, 1.5 L) this past week again yielded 45 mpg. :-) > Last month I replaced > [quoted text clipped - 25 lines] > little more, > about 25.7 miles / gallon.

(I will work on items listed) My Accord is LX 4 cylinder and automatic transmission. It should be 2.3 litre engine. I think tire presure is 30 PSI. Daily usage is more city driving. There is one issue, after transmission change sometime it seems that all the power of generated by engine is not transmited to wheels [I could hear engine moving and car not picking up that quickly]. Usman >> > Is 23.3 miles/gallon OK for my Accord ? I am expecting >> > little more, about 25.7 miles / gallon. What do you [quoted text clipped - 6 lines] > usage is more > city driving. fueleconomy.gov says EPA estimates are about 19 city, 27 highway for your car. But the site also now has individuals' experience listed, suggesting your mileage could maybe be higher. Hard to say without more info. Buy a good tire pressure gage and check the tire pressures yourself. The "recommended" tire pressure should be printed inside the glove compartment or on one of the door jambs. Many of us here keep the tire pressure much higher. E.g. my 91 Civic's "recommended" pressure is 26 psi. I now maintain it at 32 psi, checking every few weeks, especially after large, seasonally-driven temperature changes. The higher pressure gives better mileage but a less comfortable ride. > There is one issue, after transmission change sometime it > seems that > all the power of generated by engine is not transmited to > wheels [I > could hear engine moving and car not picking up that > quickly]. Do the little stuff listed first, then take an average of the mpg over say a half-dozen tanks of gas. Report back. >> Clean the PCV valve next, using carburetor (PCV) cleaner.

I have a '98 Odyssey with the same drive train. It gets 20 - 22 in fairly hard city driving. Given the greater size and weight of the Ody, I would think the Accord should do at least a couple mpg better. How sporty is your driving and how heavy is the traffic where you are? >There is one issue, after transmission change sometime it seems that >all the power of generated by engine is not transmited to wheels [I >could hear engine moving and car not picking up that quickly]. That sounds like the transmission slipping. First check the fluid. If it is low, burned or if you aren't sure that it is genuine Honda fluid less than 40K old: change it by the drain, refill, drive, repeat method. Do not let anyone "flush" it. If that doesn't fix it, start saving up for a transmission. | Is 23.3 miles/gallon OK for my Accord ? city / highway ? # of cc ? www.epa.gov/greenvehicles/smcar-06.htm Mpg is difficult to compare, e.g. [i] the more times engine must heat up ( open loop, high idle rpm when cold ) during a measurement period, the lower is mpg. [ii] if tyres have nitrogen, or tyre walls are softer, or toe-in is zero, then rolling resistance is lower, more mpg [iii] if oil used is cheap & coarse, then more friction & lower mpg esp on highway. [iii] 1 driver may accelerate hard & never coast, another driver accelerates slowly & always coasts. [iv] 1 driver must drive in rush hours, another can avoid rush hours. |
