Im wondering what you guys recommend for oil for all year use? been reading that 15/30 is a fairly standard affair?

Just don't ask this question on vzi, you'll get flamed, someone asks this question every couple of weeks without searching for it and it usually gets messy as everyone has their own favorites.

The only bad oil is oil that is dirty or too low.

IMHO the best oil for an a/c VW is a regular 20/W50 or a 15/W40, no need for anything expensive, just change it every 3000 miles or once a year, supermarket own brands etc. are fine.

I'm currently running mine on Viscol 10/w40 semi synth (£9.99 for 5l from Home Bargains) because it's cheap but I tend to add 1/2 a bottle of STP to bulk up some of the 'old engine' additives and because I used to like the stickers when I was a kid.

As I say, everyone has their own favorites, there isn't a 'best' oil and you'll find anything that says 'motor oil' on the can will be much better than the straight 30 oil that VW recommended until mulitgrade oils became popular in the 70s when they changed their advice.

This is what they recommend now, basically anything...



.

I've always used 15/40 mineral oil don't use fully synthetic oil as this doesn't remove heat that well in air cooled engines... I found out the hard way a long time ago with a new engine in a beetle.

I saw the thread you were involved in a week ago. Some not very nice people on there and expect everyone to have the knowledge of a expert. In my situation thats not the case 

Spoke to Tim Flynn yesterday and he said to use 15/40.  If anyone will know he will, 50 years in air-cooled engines and trained by VW.

Good old fashioned Duckhams 20/50 can usually be found for about £8 at your local cash and carry 

cheers guys! tbh i rarely go on vzi apart from there buy/sell which is fantastic.

so many ass hats trying to be cool when theres people who are often pretty stummped and seeking real help.


ill see whats cheapest out of them and go from there. it seems like some sump plate bolts have been over tightened at some point so will be interesting getting them off
