What is the recommended oil viscosity for a 250000 miles 98 Honda Civic LX

The engine is not idling, but tends to run about 500 rpm when initially hot and vibrates excessively as it were gonna to turn off. I have poured it about 4 Qt of HM 5w30 oil and add a 16 Oz STP oil treatment b ottle.

SOURCE: idling problem when ac turned on honda civic lxi 1999

Hi,

To my knowledge (at least in my country), some Honda Civics have a compensator solenoid the pushes on the throttle that adjust the engine's RPM to its standard idling when the A/C compressor is activated. Technically, this solenoid is nothing more but a coil and a plunger. When the compressor runs, the same relay activates this solenoid and pushes the plunger forward increasing the RPM. Pls check/clean/adjust/replace as deemed fit and necessary.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

SOURCE: 1992 Honda Accord EX 4 cylinder automatic [engine RPM change]

Hi!

It seems to be clutch problem.

There is a way to slightly adjust the idle,on the front of the throttle body where the intake boot is bolted on,abovt the boot and slightly to the left you will see a hole about 1/2 inch wide and it is plugged with grey epoxy like material. Using a flat head screw driver scrape the epoxy out of the hole and there is a flathead adjustment screw. You can adjust the idle up and down just a few hundred rpm. Hope this helps and let me know if there is any more direction you need.
Please rate this solution.

Thanks

SOURCE: timing chain maintenance

It's actaully a timing belt, not a chain. But the mileage recommendation i believe is 60,000 or 90,000 miles.

How do i replace alternator belt on 96 honda civic ex

1. Make sure you have a detailed description of the noise is concerned with, including whether the noise is occurring at idle or above idle speed (does it disappear above 1,200 rpm), and if the engine is cold, hot or both when the noise is occurring. These engines generate a lot of "normal" noises 2. Determine what environment is in when the noise is most noticeable to them (inside passenger compartment, next to building with/without the driver and/or passenger window open, or beside the wheel well). Validate by using your own perception. 3. Compare the noise generated with a new vehicle, if available, with an ENGINE build date of 3/30/2005 or later on Mustang and 4/18/2005 or later on F-150 to F-350, Expedition and Navigator vehicles. if the noise is the same, the noise is normal and would be a characteristic of the vehicle. Do not continue with this bulletin. 4. Diagnose noise when engine is at normal operating temperature. Verify oil temperature by using a diagnostic scan tool and monitoring the engine oil temperature. 5. Check the type of oil filter installed on the vehicle. A dirty or clogged filter may cause a pressure drop. Look for aftermarket brands not recognized in the market or a production filter that has gone beyond the standard Ford recommended change interval. 6. Check for signs of oil brand used and viscosity. www.careucar.com
tip

I have an 1988 Honda CRX with 288'000 miles on the original engine with no work...

Believe it or not, it is normal for these engines to use about a quart every 2000 even when they are essentially new. Note that I said, "use", not "burn". The combination of higher compression and operating temperatures causes oil to pass through the engine. You might notice your tail pipes have a good coating on the inside. I managed to slow the process by converting to Mobil 1 0W40. I get much better performance and I only use a quart every 3500-4000.

I have a Honda civic LX 2009 and the RPM is 700. I understand that the normal RPM is 900. What could be the reason of the lower RPM on my car? Thanks in advance for your comments

I think the idle, in gear, should be about 750 rpm, definitely not 900. If you are looking at the tachometer, it isn't that accurate visually. a scanner should be connected to get an accurate reading. A little vibration at idle is not abnormal. But you might try adjusting the engine mounts to eliminate it.

Hi i have a 98 honda accord lx and i wanted to know wether it was my trammy or the clutch because when ever i do a rolling stop or if i had jus finished backing up nd as soon as i put it in drive and press...

I had the same problem on a 1998. The computer controlled mixture at idle is not working right, and idle is dipping below 700 rpm. The culprit was a dirty throttle body intake. This tends to foul the plugs as well, after a few minutes of idling, so i would recommend changing the plugs after you have the system cleaned. The problem is intermittent because at high engine speed, say 3000 rpm, the plugs clear up and work normally.

My car has 140,000 kms hw often do i need an oil changeits a 1997 honda civic

To keep it simple: Your car should have used synthetic oil originally:

If you are using Regular Motor Oil - I found through many years of doing oil changes & auto repairs that 3000 miles is the MAX you should drive before changing. After that it tends to lose it's protective qualities & you can actually feel the difference (once you've removed a few thousand dipsticks) in the viscosity.

Synthetic Lubricant- Higher Quality Products will make your car last longer & I can suggest no better improvement to anyones vehicle than to use Synthetic Oil. Change at 6000-7500 miles depending on type driving. City, Idling a lot, hard driving = 6000 & Cruising/highway regular speeds=7500.

Always make sure your air filter is clean & a new Oil filter is installed each time as this will keep the new oil clean longer which provides better lubrication & performance. Some car Mfgs say to skip oil filter change & do every other but I like the results I have rec'd with changing it each time. It also helps to keep the new oil cleaner by not mixing in the dirty oil that is in the filter & associated piping.

If your car is running well, stick with the 5W30 that was recommended as Honda engines are extremely close tolerance. If it has used regular motor oil & is a little noisy, during the warmer weather you could step up to a 10w40 or even better a 15W50 in the summer, preferably Synthetic. Better fuel economy, acceleration & less wear & tear.

Finally: 140K should earn you a badge. That's just a well broken in Honda if it's been well maintained and you should expect much more service from it. I hope that this helps. Good luck!
