Polo GTI High Oil Usage - Discussion Thread

Is that from a complete fill of Liqui Moly or simply topping up the Castrol (or whatever is in the car from new)? I've been topping up with Liqui Moly, and the level is still going down a little, but maybe it's the stock oil literally going up in smoke.

Castrol for me? No f**king way!

Is that this one Gavs?

My GTI is now just over 9000kms and the oil light came on. Checked the stick, just a little oil showing. Dropped into the dealer and they topped it up with two litres. I also bought an extra 1L bottle to keep in the car just in case.

Complete full mate.

LocoPolo yep, that's it

If you guys can reccomend somewhere that stocks the Fuchs Titan in Oz it would be appreciated!

I've tried with Bardhal C60 5W30 Low Saps, but the consumption didn't change....

I wonder how Penrite's "Extra Ten" fares in these engines.

Penrite Oil - A Better Class Of Oil

It only has 502.505 Approval, but thats fine if you're not on longlife servicing (ie Australia).

I really don't think it's a problem of oil, the problem it's on the engine!

Here we have a lot of examples of people who tried to change brand, viscosity, mineral, semi-synthetic, specification, etc, etc, but nothing changed...
Furthermore, this engine has high swings in oil consumption, depending on the way is driven, external temps and many other factors not always easely understandable, so I think that if you noticed variations those are not due to a different kind of oil...

Basically I agree with Varnak when he says that "the cave/cthe engines a major failure of the group. I consider their chosen path of action (act like nothing happened and deal with its case separately instead of a redesign and recall ) an insult."

Factory fill is repsol for Seat, oil does not make such a huge difference in my experience.

Bare in mind that dealers stock different approved brands per brand name. Audi has Kolben (rebranded divinol), seat dealers had divinol , now have castrol , same for VW they use Castrol. That is why lubricants adhere to standards certified by third parties. Anything that covers vw504 is good enough.

In my experience with three different oil brands i noticed very minor differences.

1.5 mm is about 200ml so you are consuming about a lt/ 10k.

My friend for me is dead simple what is going on here. The twincharger engine was, in euro4 format, an excellent unit with the only criticism from rivals being its high emissions. Here in Europe emissions are of high importance since we are getting taxed based on them. Also note that the last cavd engine could not go to production (being marginally euro 5 on the scirocco).

60 per cent of the mechanical losses of internal combustion engines are due to cylinder piston ring contact. What to you do to reduce emissions ? You reduce tension between the two. Well in theory that produced the perfect engine with 138grams/ almost 200 hp stock and consumption only up by 10% when compared with cavd units ( still very sensible). In practice though they failed to accommodate for the rapid boost build up of the compressor with the new piston/piston rings setup, thus the screw up.
Can they sort the problem? Of course it is dead simple: just change the piston and piston rings back to CAVD specs, there! Problem sorted.

Can they solve the problem and meet emissions standards as advertised? NOT A CHANCE. Thus they are pretending nothing is wrong as a strategic decision. The VAG group would not admit to such a major engineering screw up. They will happily change as many engines as you want while in warranty until they produce the mk6 polo/mk6 ibiza with a new engine line up.

This is accordance to their first attempted fix of installing thicker piston rings ( i.e higher tension) but obviously that was not well thought out either, or not well executed by dealers.

So if you like the car and want to keep it, find a good local garage buy 4 piston and piston ring sets from a CAVD engine and off you go. A lot of guys down here have done just that and solved their consumption issues. Some even tried aftermarket piston ring sets and that solved the problem. Of course you need to re-hone the cylinder walls before installation.

Sorry for the long post but hopefully it brings some light into what is going and a propose a tested solution.
