Polo GTI High Oil Usage - Discussion Thread

Stay in M mode, Keep your revs above 2k rpm and your problem should go away.

Why avoid the problem? Keep driving in D and get repairs done while you are in warranty. I got my car back from an engine rebuild last Friday. I have not driven enough to check oil consumption, but I gave it a hard time on the weekend, and not seeing any black soot/oil in the hatch. Fingers crossed it stays like this.

Ok so now my car is getting the engine pulled apart so they can have a look at the pistons....

Well in that case Zak stop driving it hard I bet u anything the oil consumption and soot will come back new engine or not!

Well I was only driving hard because I was without it for 3 weeks and also proved that my heavy sooting is gone. It is now being used as a daily drive so, I will update this forum in the coming weeks. I only drive around 200km a week so give it a month before we can see if the oil is still around 1L/1000km as it was before the engine rebuild.

Ok this is my theory..... All 1.4 twinchargers have some kind of design flaw in that they have noticeable oil consumption and exhaust soot during low engine speed (below 2000 rpm). By not using the D mode at all ( which is designed to keep revs very low and thus improve fuel economy) these people are seeing oil consumption improve to around 1L/8000 -10000km and cleaner tailpipes.

Not a bad theory but the only reason that there are issues is because of sh*thouse manufacturing. The higher rpm is also generally attributed to lighter throttle application so there is less pressure in the combustion process due to lighter load. Yes it's a band aid solution but that's not the point.

The point is that there shouldn't be any need for the consumer to have to accept a substandard product just because the manufacturer is too stupid to fix it.

Maybe just remove the supercharger belt?

Maybe they can't easily fix it...
It's like Mazda and their new SkyActiv Diesel. It was a mess when first installed in the CX5 (massive crankcase oil dilution with diesel). And the response from Mazda was similar to VW. Took 8 months for a "solution". Not to mention their spontaneous burn the car to the ground iELoop in the Mazda 6.

Anyone tested their engine with a different weight oil or is everyone too afraid to void their warranties?

I have to agree with this. If I wanted to drive a car manually all of the time I would have bought a manual car...

On topic, has anyone concluded whether they use more oil doing city or highway runs?

For me, the only time I noticed a significant difference was during some really hot weather (35-40 degrees) when my car used 3-400ml in about 800km. Prior to that it was averaging about 1L per 4000km, and since it's used about 750ml in 4000km (there was an oil change in that 4000km, though).
