What oil is best for my ed30

(1/3) > >>

Hi folks, I have an edition 30 on 113k miles that is un tuned. Its always had vw servicing so the oil has always been castrol long life 5w30.
The consumption was excessive but within vw guidelines. Last week was the first time I took it to a specialist for a service and I mentioned the oil usage. They said they'd change the grade to 5w40. After the service I asked what oil was in and was informed its running on 10w40 triple qx.
I'm unsure whether this will be suitable after reading about recommended oils however there are so many conflicting arguments and I'm confused as to what grade a high mileage stock eddy should use. Or just go back to 5w30 and keep topping up.
If anyone could give me advice I'd appreciate it thanks

5w40 millers nanodrive for me, oil consumption is almost nill since changing. Ko3 gti on stage 1 tune with a fair amount of track days.

I've noticed recently that a few people racing the tfsi motors using 10w50 or 10w60, can't quite remember which! Obviously those engines run under different circumstances though.

I've had high oil consumption for the 8 or so years I've had my car.   Uses average of. 1l every 1200 miles.

Tried Castrol Edge 5w30, She'll Helix 5w40, Triple QX 10 w40.  All about the same.

Last oil change I used Miller's CTS nanodrive (as mentioned above) 5w40.  Since then oil consumption as more than halved.  Not topped it up yet.  It's used about 0.5l in around 2000 miles, but if need to check that.  Essentially it's much better since Miller's.

Other things that helped in the past - new PCV, new rocker cover.

Get the engine up to temperature, or after a longish run, let it idle for about 5-10 minutes, then mash the throttle down.  If it kicks out blue smoke, that is where your oil is going.  Valve guides and/or seals are shot.  Under normal driving conditions you don't notice the smoke as you don't generally idle for 10 mins or more, unless stuck in traffic.

If not guides and seals, it will be knackered piston rings, so get a compression check done to outrule that.  Worn turbo bearings can weep a bit of oil into the exhaust as well.

Mobil 1 5W50 is good for reducing consumption, and not a bad idea for engines past 150K anyway tbh.

Thanks I'll look at changing the gasket. Is yours stock?
