Polo GTI High Oil Usage - Discussion Thread

[kawabanga]

Kawabanga, how often does your motor pass 5000rpm?

Over 5.000 probably twice a day, my average driving style is about 3.500/4.500 rpm with half gas charge, also some floors sometimes...



BTW, a couple of bad news from who installed the new breather pipe:

Italy: Ibiza's user, 1 liter per 2.000Km, exactly as before Bocanegra
Germany: GTI's user, 1 liter per 1.700Km, exactly as before GTI

If this is the tendency, I'm looking forward to see what VW will say and do now...

DONT baby it - thats the worst thing you can do. Once the engine is warm, load the engine up up as much as possible (floor it from low RPM in say 3rd or 4th gear and really get the turbo/supercharger working the engine.

Why is it the worst thing to do?

By babying I mean, driving it like a normal car, as my daily. Basically let 'D' do what it likes to get me from A to B.

[Lucas_R]

^ i meant babying it is not good. You need the turbo/supercharger boost pressure to help expand the piston rings by giving it a good workout - this will help ensure a well run-in motor and help against possible oil usage issues which plague the Polo GTI engine.

At 600km, the best thing you could do would be to take the car for a good thrash. Im not implying burnouts etc, but some good full throttle runs throughout the entire rev range.

Pointless now, the damage has already been done. You have 100kms to get the run in done correctly of you use the "load it up" theory as I did.

[Lucas_R]

^ agreed. The first 100km or so is by far the most important. My car had 23km on the odo when i got it and i started the "loading it up" run in procedure straight away.

My brother currently works at Skoda but has also worked for Audi previously - and he runs all the new cars in this way before delivery to the customer.

I think by 3k i will do a oil change witht he Moly and also replace the oil filter and plug. Where did you get your Moly from and whats the price like? Thanks

Try Mobil 1 ESP 5w30. Its working well on my PGTI

This Italian Ibiza 150hp user just had a dyno after software update, he found the same power peak as before (if not a little higher), but a significant torque reduction at low revs.
It seems that the volumex has been inhibited...
This could confirm the theory that there is too much blow by at low rev, due to supercharger action.
Our engine has 250Nm at 2.500rpm, really so much for a 1.400cc gasoline powered...

Interesting, pointless if you get a tune though. Sounds like tail chasing to me.

If blowby is such a big issue, why they don't fit an oil return catch can type setup is beyond my comprehension.

Could I grab a link to this "load it up" theory? I cant seem to find it using search.

Lets see what I did wrong

very weird thing happened. Just checked my engine oil and before literally a week ago the dip stick went half way now it is all the way at the top?

The way i checked it was let the oil warm up (90 degrees), turned off the engine waited for a good 5-10 mins parked it on the flat surface. Pull out the dipstick wipe it clean and do a another dip (that is putting the dip stick all the way in into its original level) then pulled it back out to examine the level. THe level is now beyond you maximum level (the dealer did the top up for me and he did say he added 1.4L into the engine (that was when the engine was dead cold got the car towed there). Is this the correct way to look at the level?

[gavs]

What you did, yes. The dealer however has f**ked up because the oil needs to be at temperature to be properly checked. You should also only add 500ml at a time, not 1.4L in one hit!

So good news for me.

6,500km in and the oil issues seem to have dissapeared. It has drunk about 3L of oil before the first 6 month / 5,000kms service - but i had a consumption test done at 6,100kms and it had drunk 100mL over the last ~900km. Going back at 7,100km again for a further checkup, but so fingers crossed it stays this way. The oil spitting appears to have stopped as well.

self healing miracle engine, GEE.

Since july 12th not used D-mode but only S-mode and ESP off, it seems that it have some effect for the oil consumption, new oil not added since 12th july. It seems that D-mode and high gears with low revs causing some problems (supercharger may create too much internal engine pressure?). Not sure but please test it you too, thanks. Anyway the car should work also in D-mode so that's not the official solution but might help with high oil consumption. My engine checked twice and nothing repaired or they just don't tell me. Oil usage measured to 0,3 litres per 1 000 km.

I don't think that has anything to do with it because when the supercharger is not being used, it switches off. in fact, unless you are using something like 30%+ throttle application, it won't even engage from a standstill so I think it is more likely just coincidence that your engine has probably just "settled down" with it's consumption. Did you happen to change oil brands in this time?

NO surprise really that the miracle pipe has not done it's thing, so I will be looking at another means as talking to an engineer of another major car company that has suffered major oil consumption issues in their v8 turbo diesels, there can be a lot of masking of the true oil consumption just by checking the dipstick. To be honest I didn't fully understand what he was saying but my basic chemistry understanding said that all that is in oil after 10,000+kms aint just oil that is making up the volume....
