Hi all
My 2008 2.4 VTEC all wheel drive CRV is giving me about 7.5 K/L
I intend changing the spark plugs.
The motor operates at about a hight of 4500 from see level.
What plug grade/make will this forum recommend.
I also have the problem with the steering that jurks when turned hard.
I'm going to change the o ring and clean the filter as recommend in another discussion.
Please gents.. some Help with the low gas milage.
IV lot's of respect for this forum.

You should use an Iridium spark plug that is the same brand as original. That would be either Denso or NGK Iridium plugs.
Another thing that helps is to adjust valve clearances.

Our plugs were almost perfect when I changed them at 120K miles.

We changed our PS fluid at ~ 100K miles by sucking the old fluid oiut with a turkey baster or syringe. Never had an issue with jerking steering, though. We ALWAYS let the car roll when turning.

Welcome to the forum! It might help to tell us where you are, or where your CR-V was made. I see your flag, but it has no label, and we don't have a flag picture index to help us decipher where you are, considering that there are close to 200 possibilities. Your owner's manual will have a listing for the recommended spark plug. Also, for those of us in North America, who are not metric literate, an MPG figure might be helpful. And you might get better results posting this in the Gen3 Section rather that here in a generic one. We are about to overhaul the forum, and the Maintenance and Service Section will be closed anyway, so this post would be moved there anyway. Good luck, and let us know how this all turns out.

Yes, a couple months ago. I am developing the overhaul for the Table of Contents Page, which is now done and about to begin. It hasn't been updated in boucoups long time! The new version will be a huge improvement, but it will take a lot of work and quite some time to complete, so stand by!

Thank you for the Welkom...
As a response to your question, I live in South Africa on the bottom tip of the African continent.
Regarding my 2008 CR-V it was manufactured in Japan and imported into Botswana directly from Japan.
it is a righthand drive model with a 2.4 litre petrol/gas motor with all wheel drive. I presume it is manufactured to the UK specifications
3,8 liters to a US gallon so my CR-V is doing 7,5 kilos per liter of petrol/gas (1.609 kilometers= 1 mile) that equates to about 28 MPG.
I also own a 2016 c 240 Mercedes Benz and a 1998 Mark 5 Ford Escort 1600
the MB gives me an average fuel consumption of about 13 k/L and I use this as a benchmark for a 2.4L motor as my previous 2000 c240 did about the same on fuel even after covering 400,000km
The CR-V Honda vehicle is new to me as a gift from my Daughter as I am no longer ficically able to maintain my cars any longer.
I question the Spark plug as I'm concerned that the plugs have done their duty.
The steering on the car is annoying as it pulses when held in a constant angle going around bends. I will clean out the steering pump reservoir as suggested on this forum but am unsure as to the location of the "o ring" that was mentioned.
thank you for your time.

Because that happens at road speeds, not parking lot speeds, it points towards a bad tire (belt shift) or bent wheel. Best diagnostic is to switch the tires front-to-back, and while doing that, make sure there is no dirt or corrosion on the wheel-to-hub mating surfaces. Any change in the indication means you found it.

Bent wheels can be determined visually, or with a dial indicator. Only a few thousandths' run-out can be felt in a steering wheel. Are the wheels Genuine Honda? Wondering about hub-centering... ?

++++++++++++

Regards your fuel usage comparison, bear in mind that the other vehicles you used as a benchmark are lower, and offer less wind resistance at highway speeds. Additionally, CR-Vs of that era are geared more for off road, and as a consequence the engine turns at a higher RPM at most speeds.

I still think that doing a valve adjustment will help with fuel usage.

I calculate 7.5 k/L is 17.64 U.S. MPG . That is low, you should easily get 22-24 mpg (9.5-10). The steering issue may be a clue, something binding. Way out of alignment, dragging brakes, loose suspension parts.

It is on the power steering pump's inlet joint. If yours is the same as mine, changing that O-ring is a 5 minute job. The old O-ring is black, the new one is orange, at least here in the USA. Probably made out of a different material.

According to my ASE technicians, you want to maintain proper tire pressure, keep your air filters clean, use top tier fuel (with the octane required by your owner's manual), use API synthetic motor oil at the proper grade, and do any other maintenance that needs completed (to include spark plugs -- NGK or Denso Iridium [NGK is best]). I have observed all of these and I get 26-27MPG average in the 2012. As far as the steering, take it to an ASE technician and have the fluid flushed with Honda PSF.

To me 7.5 K/L is about 29 MPG. My 2006 2.4 AWD 240,000 miles gets 25 MPG no matter what speed I drive. Trip trough North Dakota @ 85 and a head wind unfortunately was 24.

Tanks everybody for the feedback. I've had the wheel alinement checked and it was within the recommendations I found and changed the "o-ring" in question and flushed the transmission oil from the steering box also cleaned the reservoir for the steering oil but found no fault with either the o-ring or the sieve in the reservoir. the steering pump is to noisy for my liking! I will investigate it a bit further. Is a refurbish kit available in the USA?
The wheels where moved front to back when the alinement was done the vehicle is not used and was not used off road at any stage. I do have a noise emanating from the front suspension that I have identified as a shock absorber mounting that I will replace it when it arrives from Japan. I am going to change the plugs over the weekend and then I'm going down to the coast for a few days, (500 mile trip one way)

Hi,
Regarding the high rev motor as you have indicated. I have checked this and found that at 120k/h (70 m/h) it revs at 2400 rpm. that is far lower than the Mercedes that runs at about 3000 rpm.
I'm not sure about the valve issue as it has a I-vetch 2.4 dohv motor that has hydraulic cam followers.
the wheels are genuine Honda wheels but the tyres are of a south African brand recommended by the tyre depo.:)

If that is the case, and your engine has hydraulic valve lifters, no adjustment is possible.


North American 2.4L K series engines all have solid lifters that require periodic clearance checks.
