Polo GTI High Oil Usage - Discussion Thread

[alexaescht]

Mine has shown evidence of burning oil quicker in very hot weather (i.e. over 40 degrees). Normal consumption is around 1L/4000km, but it has been double that after a week in which temperatures have been around the 40's.

Which makes sense as the oil is thinner due to it being hotter so it can creep past rings etc. more easily.

Here's a strange situation. MY13 CTHE polo gti I've had since late last year.

Oil light first went on around 7300km, not a big deal as that's ok consumption for this engine.

Put in 0.5L of Penrite enviro+ 5W30 because I intended to get a full oil change pretty soon anyway.

Tonight the oil light went on again at ~8450km, so what apparently that 0.5L got used in only around 1150km?

I put the second half of the 1L container I had in tonight to keep it going but I'm a little worried that my oil consumption would somehow be so much higher now than it was for the first few months I've had the car. There aren't any oil spots where I park it and I can't see any oil leaking in the engine bay. Is it possible that the penrite for some reason just got consumed way faster than what was in there from the factory?

0.5L doesn't sound like enough if the oil light came on - maybe I'm wrong on that though.

have you had a change in your normal driving conditions? More longer trips that would burn off any light hydrocarbons or moisture in the oil. Higher ambient temps leading to higher oil temps?

For those of you willing to take a punt, GLlubricants sell Mobil1 502.00 spec in 0w-40 for $12.00/qrt (950ml). I'm running it in my 1.8tsi & find the initial 15 second start up rattle has dissapeared & the 40w should provide a bit more protection in the heat. Just a thought for those out of warranty or willing to think slightly outside the box.

There is no risk to the warranty if the product has been approved to VW standard 502.00 or 504.00, irrespective of brand or viscosity grade.

Mobil 1 0W-40, as with any product with 502.00 approval, can be used for all petrol-engined VW models not on the LongLife service regime (i.e. all models bound for the Australian market).

You & I both know that but we have both seen how conservative most owners are & how unwilling they are to (a) read the owners manual & understand what is written & (b) do anything different to what the uninformed drone at the service counter tells them.

Because many believe using the 502.00 in the new petrol engines could make the cars go KABOOM!! :p

Or (C) they know perfectly well and prefer to use 504/507 oils because they are a higher grade of oil (Both SAPS as well as better lubricating properties), even though they know that 502/505 oil is generally cheaper to buy and is acceptable (except for new diesels)

I have a friend who drained it immediately after his mk6 gti had had 502.00 oil filled into it.

I noticed most photos of US mk6 gti's with 502.00 oil do get much worse carbon build up than a photo of the intake valves of a mk6 gti with 75000km in melbourne.

As usual, people have failed to miss the point I was making regarding using a 0w-40 instead of a 5w-30.

Yes we know what you are saying but just because it has better numbers doesn't actually mean it is lubricating any better.

You have to remember the numbers define the average viscosity of the oil at a given temperature - not its lubrication properties and its ability to stay bonded to the metal. Yes old oil was simple to understand - thicker when hot good, thinner when cold good.

But that is not the case with new oils. The 5w-30 has lower viscosity so that it doesn't drag the engine down thus saving fuel while offering lubrication properties far better than old oil of higher grades.

I'll spell it out.

This is the high oil consumption thread.

For those that are experiencing high oil consumption & are at the end of their tether - possibly out of warranty & talking to the hand when at the dealership, the higher viscosity at a given temperature may reduce oil consumption. Hence my use of the term "take a punt".
