Hi,

 

I’m new to the forum but have a question regarding the turbo on my Octavia 3 VRS TDI. I’ve had unusual oil consumption of 500ml around every 600 miles. I know this is within tolerances but still is high. Mileage is currently 63k. No running issues runs very smoothly and quiet for a diesel with plenty of power. After looking around I took some photos of the turbo. I’ve noticed it has what looks like a billet compressor wheel on the intake side. Is this standard on the oem turbos? 
 

I’m very confused as I also notice mine picks up from standstill slower than my friends but mine picks up higher top end. It’s not currently tuned as far as I am aware.

 

I’ve tried getting advice with no luck. If it is a hybrid this would be great as I’m looking at tuning options. Any help would be appreciated.

 

Thank you ☺️

I’d certainly not be looking at tuning options if you are using that much oil… 

my last octavia and superb diesels have both been mapped for 100+ miles and haven’t used anywhere near that amount of oil. 
someone else may have had a different experience but I’d be looking at oil use before tuning !! 

The part number should be printed on the side of the turbo somewhere.

My priority is sorting the oil mystery out however was wondering if some work had been done by the previous owner hence the high oil usage. There is zero signs of smoke, no signs of any leaks, dpf has zero issues not thrown any CEL lights which seems weird. MPG is great with high 60’s easily achievable on motorway runs.

Is the dpf still in 🤔 

Pretty sure it is as it doesn’t seem to be any louder than stock and performs regens regularly usually approx once a week. Just seems very strange. My previous car went through a fair bit of oil too but was well known for it especially being a modded performance car. Switched to a 0w-40 ester based oil and the consumption reduced by more than half. 
 

Going to have a good look over everything tomorrow to look for anything obvious. Possibly change to a 5w40 too to see if that makes a difference. 

I wouldn't do that. I don't think the 5W-40 meets the 507 standard. 

You might want to look into this topic 

 

If you switch to 5w 40 just make sure it is low sapps, else it will block the dpf quicker.

The EA288 engine is known for high oil usage. Plenty of posts on here about it. If you are looking at modifying the engine the most you will get is around 280bhp and to get that you have to spend some serious cash.  Even to get to 250bhp will cost a few thousand pounds. Chances are if the dpf is still fitted then the turbo will be standard. Most who go hybrid remove the cat and dpf.

I would be looking at possibly a sticky wastegate if your car is slow to build boost low down.

@cameronjones67 Welcome.

 

Just a small point for others,

Your cars oil consumption is not within tolerances just because VW Group owners manuals for over a decade say that all engines 3,4,5,6,8 cylinder petrol or diesels 

May use as much as 0.5 litres in 1,000 km.  (621 miles). 

 

That is not acceptable oil use and if you can find in writing that that is within tolerance please link that.

0.3 litres per 1,000 km oil use has been enough for VW Group to have to replace engines under warranty.
