What is it with people hunting round for cheap ****e oil?
Wilco is not the stuff t use if ya really give a **** about ya vehicle
Use quality oils AND change regularly
if you go up to your local recycling centre and distract the meanderthals working there you can ladel out some used old engine oil from their tanks for nothing !!!!!!!!
In a TDI Landy its not so critical. No point wasting £40 on 5l of Castrol Edge when it will probably do more harm than good as the previous owners will have used a cheapish mineral or semi.
I look for good value for money hence using the chevron semi that meets ACEA A3:B3 specification.
Personally I'd rather spend a bit more on oil than replace an engine... but that's just me...
