Hi guys,
I bought a Golf MK 4 (Engine code ARL)about a month ago, and sadly did not pick up the pop sound from a valve.
Last week I got oil pressure alarms randomly appearing, spoke with a good VW TDI guy who said it could be sludge build up in the oil pan or possible a defect pressure switch.
He suggested I ran some oil/ engine cleaner in it which made the alarm dissapear, which I think indicates it was a sludge problem.
Above issues made me look thru the stack of receipts which followed the car and found lots of castrol long life oil receipts, and I suspect this could be the root of the problem.
I also own a Passat with basically same engine (less hp smaller turbo etc.) which has 365.000kms on it with no problems at all, I always ran 15.000km OCI and only approved VW 505.01 oil (MOstly Motul X-Clean 8100)
I'm looking to find the absolute best oil for this engine, which seems to be something that handles soot good and protects the cam well.
I have been looking here, googling and what not, but not convinced of anything.
Here in Denmark it's not so easy to get UOA's or I would be doing that to find out.
I have been considering just continuing with the Motul 8100 50501 approved (has the most approvals of the oils I can find)
Or try Redline which is significantly more expensive but alledged has a very high film strength and cleaning abilities..
Anyone got any input on what is the best to use in my case is much appreciated.
