Since your car is 120k km driven you need to get its valve clearance checked (it is recommanded at 100k km)
Also if your fuel filter is chocked your car wont pull like it should and consume more fuel than it should
Make sure your injection pump timming is correct
And try LM diesel purge to clean prechamber

Average city/highway?

uusman1 (Usman) 2018-02-06 17:21:00 +0500 #4

Average was within city 12 + and highway 15+

uusman1 (Usman) 2018-02-06 17:21:56 +0500 #5

Fuel filter was replaced at 80k. And by valves u mean nozels? Or valves are separate ??

saboor73 (Saaboor A saad) 2018-02-06 17:32:41 +0500 #6

Valve clearance = tappets

pwuser151438268980 (Muzammil Nawaz Nekokara) 2018-02-06 18:24:13 +0500 #7

Valve clearance, check air & engine oil filters, diesel pump tuning if required.
Do you have any issue regarding cold start & whether your car reduces engine oil?

uusman1 (Usman) 2018-02-06 22:10:50 +0500 #8

Since last one year it jst once created problem of not start, might be battery not providing enough power to pump, now replaced battery. All ok but not satisfied with average. Air and oil filter is new. Fuel filter is checked and is also ok

pwuser151438268980 (Muzammil Nawaz Nekokara) 2018-02-07 10:59:39 +0500 #9

Get diesel pumped tuned & only use selected fuel pumps for diesel especially Total, I use the same. Next time add fuel additive such STP or LM for diesel car 2-3 consecutive uses should clean your engine.

Diesel pump tuning involves some machine or manual?? Also i got timing belt and bearings replaced 2 days before but my mechanic didnt use dial guage to adjust timing. Instead he insisted on signs of pulleys as before. ??

diesel filters are to be replaced every 10k kms, so get that done. Get your pump checked, may require caliberation or replacement as its crossed 120k kms, valve clearance(tappet) needs to be checked, is it generating smoke? or has any issues with acceleration?

uusman1 (Usman) 2018-02-07 11:26:27 +0500 #12

Acceleration is fine. So i need to get fuel filter replaced . Smoke is not too much.

pwuser151438268980 (Muzammil Nawaz Nekokara) 2018-02-07 11:56:31 +0500 #13

Thats how most mechanics do so, take your car to an established diesel lab. & have the pump checked & tuned if required.
More details on smoke please.

uusman1 (Usman) 2018-02-07 12:03:16 +0500 #14

Smoke comes on hilly area only when car needs next gear

dayrider (dayrider) 2018-02-07 12:06:21 +0500 #15

There shouldn't be any smoke. Get the pump checked

uusman1 (Usman) 2018-02-07 12:10:49 +0500 #16

Can u suggest some reliable diesel laboratory in rwp islamabad?

Just chill..ur car is fine..avg is also not bad...also depends on load and driving style

pwuser151438268980 (Muzammil Nawaz Nekokara) 2018-02-07 12:31:19 +0500 #18

Smoke on hilly areas/inclines is normal.
Try to use fuel additives & diesel-pump tuning as I mentioned in my earlier post, as there is no other issue with your car.

dayrider (dayrider) 2018-02-07 13:06:45 +0500 #19

There is one on ijp. They say that is very good.
I get mine done from Peshawar, so I haven't tried the one here.
And fyi, average should be minimum 13 with AC. Mine is a 2006, does 15 local
