Polo GTI High Oil Usage - Discussion Thread

What does this have to do with High Oil use???? The class action is something about DSG issues, isn't it?

Nope, this covers all 1.4tsi/dq200 drivetrain related issues.

Hello all,

I've got a MY13 Polo GTI which I bought in February. At the moment, I've clocked nearly 4000kms on the odometer and the amber light on the dash is showing low oil again- This is the 3rd time!
Each time, I've filled up the engine oil to full with the correct Castrol oil recommended by VW.
From this thread, it sounds like people are getting a varied engine oil usage so my question is- should I get this checked out by the service department or is this normal during the run-in period? The 3rd top up in 4000kms!!!!
A VW assistant told me the cars can use 500 mLs per 1000kms driven and it's expected to be higher in brand new cars.
When driving, I do "baby" the car a little. someone said this can increase oil consumption- is this true?

Thank you.

I have an MY13 CTH and have found on mine when driven in D mode (this keeps the rpm low for best fuel economy) oil consumption can be as high as 300 ml/1000km, 60% of my daily drive does involve freeway so rpm is over 2k@100km/hr.
When car is driven exclusively in M mode and rpm is mostly kept above 2k my oil consumption is 100ml/1000km. I have a theory that the twincharger has a design flaw in that it consumes too much oil whenever it's rpm is below 2k.

The twincharger has a flaw in that the piston rings are wrong for the size of the bores, that's the problem. It has nothing to do with rpm, that just exacerbates it in poorly tolerances engines.

vwpologti,

I would be going to the dealership ASAP but just remember that there could be a fair wait before they even consider looking at it, the dsg recall is taking priority over service work at this stage.

Should be misfires, try to look how many misfires VAGCOM counted per cylinder...
I have some..

cylinder 1 1226
cylinder 2 3803
cylinder 3 1277
cylinder 4 1097

Mileage 21,000km. I bought a new ignition coil with the surfix "G" to replace the factory coils with the surfix "F" on cylinder 2 and its still the same.

Don't forget every time the dsg changes gear, you get a misfire albeit controlled

With the count that high in number 2, have you swapped coils and plugs around to test out if the cylinder you swapped to gets higher quicker? Plug are notoriously shoddy in these too, in Europe most tuners won't even tune your car until you change the plugs.

Latest hypothesis on Briskoda is that people maybe over-filling on oil and that the excess burns off more quickly, fuelling the hypochondria that one has an oil problem. The suggestion is that the 3.6L recommended capacity comes to just under the top of the middle cross-hatched "B" section of the dipstick (when properly warmed and "rested" for ten minutes or so after switching off the engine). Adding half a litre, for instance, when one is in the middle of the B section may put the level 250ml or so over the 3.6L, and this 250ml burns off more quickly than it would from right on 3.6L.

Over analysis, perhaps. Anyone have any thoughts on the above?

If this was the case then the overfull part would burn off quickly & the part within the normal range would be reasonably stable.

I thought there was a bloke on there that fitted aftermarket forged piston which solved his problems.

Already changed a new coil on cylinder 2 weeks ago. the misfiring rate keeps increase and number 2 is not slowing down. I suspect injector problem. The lumpy feels like valve not closing properly. The plugs have been upgraded to the latest NGK Premium RX but with the same heatrange. The ceramic tip shows its burning healthy.

Yeah it does sound like fuel delivery then. THese things can carbon up pretty heavily and if you're getting blow by it does fill the intake tract with some nice black sludge. Maybe look at using an upper intake cleaner like what subaru sell or similar. Sea Foam even...

Should not have much blow by as i am only burning from Max to top of B after 4000km. What foam is that? I used to clean my throttle body and top combustion chamber every 10,000km on my previous Hondas but on VW, I am not sure how to do that. Can advice me on this? Injector should cost alot more than coils. Whats the selling price over there in Aussie? Funny thing is that it still drives well even at high rpms

It's pumping a greater volume of fuel out so that will help. Sea Foam does this: 2010 MK6 GTI Seafoam intake cleaning - YouTube

A modern VW is far more in need of intake cleaner than an older honda. Direct injection means that any carbon buildup is no longer washed off the valves by fuel, hence the need for specific oils to be used that can catch and trap carbon deposits.

Seafoam is far from being the best product out there, in fact id go to say that it's probably just the one people remember for the YouTube clips of subarus smoking like crap! Probably the best you can get is this one: BG Air Intake System Cleaner - YouTube which has now been recommended to me by 3 mechanics. Subaru sells one as a spare part, I'm not sure exactly what it's called but it couls be something like "upper intake cleaner"....

Price for injectors? I wouldn't know mate, I steer away from buying any VW parts in australia because of the 200% mark up over the european prices Should be done under warranty though.....

My car was in for a service yesterday (about 5 and a half months, and 4,200kms since the new engine went in).

Apparently its only drunk about 100mL of oil - which matches what I saw on the dipstick (only dropped one notch).

Quite impressed - Its suprising that with the (mostly) the same parts the Australian VW mechanics did a better job of engine assembly than the robots and mechanics who put my original engine together in Germany....

I'm going to hold off another 6 months and if consumption is still OK i will go nuts with a new Bridgestones, APR Intercooler and Tune.

Checked the oil today, last time I toppedup was on the 5th at 2840km. Today at 3788 I put in about 100ml while it was cold, it was 2 blocks into b and the missus was heading out so had no time to really check it with the engine warm so when she got home at 3831km it took another 100ml.
Atm its used 500ml roughly all up. I think the previous 1000km was around 130-150ml so 50ml increase atm.
The misfiring/shake at start has disappeared since I let the tank run to range of 20km and had two tanks of BP ultimate through it, previously used Caltex 98 from new and definitely wont be going back to it I don't think.

EDIT: cars been averaging about 8.0l per/100km lately
