Check if your air filter is clean. Running overly rich can sometimes have a bad effect on engine oil level.

Engine oil burning -P220

I had a similar problem from my pulsar 180 ug3 run jus 13000kms later engine also seized at 19000 Kms due to near empty engine oil (oil left was 300ml after running 470kms, there was no smoke no valve leakages, checked clutch plates and bore kit. I sold it after showroom people didn't give me warranty for using motul full synthetic oil outside showroom.. pulsar is well known for engine oil vanishing problems :/ finally u can check crank case breather pipe for any oil deposits. and also filter box cos crank case breather vomits excess oil into filter

Are you using the stock air filter / direct fit aftermarket filter, or another type of air filter? The crankcase breather is a source of oil evaporation. But you won't find oil in the tube itself. Neither does it carry excess oil. It is connected from the top of the crank case, into the filtered side of the air filter box. Also, check the cylinder head carefully for even the slightest oil stain. Oil does not really leak from the exhaust. If it blows past the piston ring, then you will find smoke from the exhaust, faint blue grey. What oil are you using? Is it (x)W50? What you mean the oil was charred / burnt? Any oil becomes black in colour after a few hundred km. Why would it cost 10k for them to check these parts? If they are already giving the estimate, then they know what part is at fault. Then why check? Fishy. Possible sources in order of probability, oil cooler joints, cylinder head, piston rings, PCV breather, drain hole, clutch cover. Please provide the details asked for a better response. Sorry for bad formatting, 'enter' key is not starting a new line!

can you throw some more light in detail, as i always run my bike too rich, and always have to keep toping up engine oil....my bike is P150. i am curious to know.

Engine oil burning -P220

I dont think engine is overly rich...have maintained standard svc settings.
Btw thanks for the approval.

The air filter is stock & i use regular oil provided by the svc guys. I haven't got the chance to check on the internal engine parts, i wish to check it tomorrow in the svc. On the oil leakage from the exhaust, i meant the stains of oil are not found in the tip of the exhaust pipe which is a good indicator of oil seeping into cylinder.

Sorry to hear about it Samarth. Will check on the air filter tomorrow.

The svc guys definitely do not know the reason for this issue but they painted a worst case scenario & expected the cost to run close to 10k.

Looking at all your responses, i can only assume that there could more to this problem than just piston rings. Will definitely spend some time to understand the actual issue with them tomorrow & will look for all the indications you have mentioned.

Thanks.

Engine oil getting burned is result of either engine oil being of poor quality or engine needs work.
did you noticed bike getting overheated or Drop in Bike performance on long rides? if Performance drop is not there you can keep doing top up.

you didnt mentioned the engine oil brand and whether bike is giving smoke or not. if bike is giving smoke then you will have to go for rings replacement otherwise you can switch to a better engine oil and check for results.

10K might be total expense for replacing piston and valve set . better get a quote from outside mechanic. expect to shell out atleast 2-4K if engine is opened. 50K seems decent enough time for a pulsar

sorry for the late reply!!

Got the service done....below items were changed:

Bore kit replaced - scarring on inside (not sure where as I could not inspect personally)
clutch plate replaced - burnt due to running on low oil
valve timing chain/kit replaced - chain had gone loose

total cost came up to 6.5k

Definitely there was considerable drop in perf over past couple of k's which I realised only after riding the bike post repair. The bike feels refreshed and very much alive now. Controlling myself to not let open the throttle...at least for few hundred kms .

Didn't change to synthetic oil, hopefully will change it during next service.

Thanks to all of you !!

M also having engine oil loss issue with my pulsar 180 classic, after 3000 kms. I found 200 ml of oil left. Didn't find any leakages.
I think replacing the block & piston will solve the issue.
guys please provide your suggestions.

Re: Engine oil burning -P220

I am facing oil leakage issues on my 4 year old pulsar 220f.
When i cruise more than 100 kmph, A lot of oil comes out from the breather pipe(which goes from the engine crank to fair filter box). When i checked the air filter box, The filter element ( which is foam) was dripping with oil.
Recently i went on a long drive about 1400 kms. When leaving for the ride, The oil level was exactly in the middle of max and min.
When i was returning i observed that the engine was heating up more & like a grinding noise, then i guessed it might be this oil leakage issue.
I stopped the bike there itself then parked on the center stand, Let the engine cool for 25 - 30 min while i was having a tender coconut water with a cigarette .
Then noticed that there is no oil to be seen in the reservoir at all !!
Since i'm facing this problem for quite a while, I had carried the engine oil bottle in my saddle bag for emergency situations like this!.
I filled like almost 200 to 250 ml oil to get the oil to show b/w max and min on the engine.

By the way, I use Motul 5100 15w50 and the bike has run for around 40000 kms, Out of which i have used a k&n pod filter (RC1060) for more than 35000 kms then changed to stock filter recently. { P.S : initial bike run in was done with stock filter for 1180 kms }
I really doubt If that K&N filter has damaged my piston rings and the cylinder block by letting dust particles inside! Which may be leading to a Blow by?
I am also noticing oil leakage from the cylinder head which may be because the cylinder head seal / gasket is gone ??

Guys, Please i Need help !! I would be grateful if someone in this forum throws light at this issue!
