Oil burn - blackened exhausts

[SAINIside]

Wondering if any owners of a new GTI Mk6 have noticed quite a bit of black burnt oil spewing from the exhaust. I've owned mine for just under a week, and the bottom lip of the chrome exhausts have been cleaned twice! I've also noticed specks of black oil building on my garage floor where the exhausts are.

Is this normal? I know they will burn oil early on their life (and new petrol turbo cars generally will), but it seems a little excessive.

Hoping it will settle down.

PS. just had the waste gate clip installed to rid it of the rattle. 5 days in and I've been back to the dealer once for a repair. Not the best of starts.

Has the oil dropped on the dipstick? I doubt it's oil. Much more likely to be condensation and soot from a rich mixture during warm up.

You're right, it's more soot than oil. Oil level doesn't seem to have dropped, although it's only had if for 5 days.

Hope the soot reduces. Seems like it's running very rich and I wonder if it's normal for the GTI?

Might need to look into black chrome exhausts!

All cars do it to some extent. Short trips would be worse, it can't run richer than it has been programmed for by VW, there's a lambda probe that tells all to the ECU. The engine needs to be at full operating temp before the lambda control works though, so driving for less than 5 minutes wouldn't do the job.

Have a look around a few other GTIs and Rs they'll all be the same.

not the ones with catch cans installed

Are you talking about fuel or oil or both ?

the oil.

i have not seen any burnt oil stain on the tips since the install.

you'd be amazed how much oil is gone with the blow by when driven hard for extended period. blow by = oil -> discharged through the pcv hose then via turbo (when in boost), then intercooler, then intake manifold, then hopefully burnt properly, then any remaining unburnt oil leaves stain on the tips.

when not in boost, it's pcv hose staight into the intake manifold.

etc etc etc...

thats also why the use of vw504.00 approved oil is highly recommended to reduce carbon build upon the intake valves.

This discussion has been done before - best to leave it alone

As soon as i cracked 5,000 kms my oil light came on... already on the low level of the dipstick

I don't think the black on your garage floor is from oil, most is soot mixed with cold start accumulated condensation from the rich fuel burning. I get black spots on the back of my car, and gave up trying to keep the inside chrome of my Milltek pipes shiny. I do a lot of low kms runs (6km each way), the car is barely in closed loop just near the end of each run, so is running open loop and rich...hence soot.

Even the fuel you use makes a difference. I have clean 'tips' after running BP Ultimate. The exact opposite with Shell VPower.

It's just soot, nothing to worry about. Just;

What Mi16 said.......
Just get onto it sooner rather than later as it, I bought mine with 12K on it and was starting to slightly pit the chrome.
Lighting chrome polish. Six bucks from the clearance bin and works a treat !

yeah.... not stressing about it. the car was a couple of days old when i wondered about this given the fact the engine eats oil like a uni student at an all you can eat buffet. I use only VPower (fuel vouchers!). Will try BP Ultimate.

I've now done 1,200 klms on the car, does anyone know when I should be taking it back to the dealer for a 'checkup' - and oil top up, because it's already down to half level on the dip stick!!!

Your dealer should have told you. We were told to take ours back at 1000km for a checkover.
