It's a car engine Jim, use car oil! The oil galleries are smaller than the trad aero engines like Continental, Lycoming etc. If you are building from scratch you have a choice of synthetic, semi-synthetic etc. I think GtPlanes make recommendations but oil technology goes on improving.
The engine doesn't actually know it's changed into an aero engine! It's also not being subjected to torque reversal (which is what kills off car engines, braking through the gears, changing down at high revs etc).
The wider the temperature range of the oil the better I guess as cooling seems to be the main issue.

I found a supplier of straight-30 'running-in' oil for about £6 per gallon. It was hard to find anyone stocking it. Not great quality but it gets changed every couple of hours during the running-in procedure. I've done 3 changes of oil and filter so far (not yet flown) for minimal cost and, hopefully, for better life due to the rings bedding in correctly. No signs of lumps in the filter and just a few fine particles showing up.
After the running-in is over I shall go with an average quality car oil.

I'd forgotten about the running in requirement of straight 30, but do wonder if it's simply hereditary memory from the days when all air cooled beetle style engines including Porsche ran on 30 grade anyway.
I have dim memories of running my 911S on straight oils in the early 70's (arghh given it away!) but agonising with my mechanic whether we should go to Duckhams 20/50.
I see no harm in using straight 30 to run-in on though. It would be good to some expert opinion on this?
I'm just about to start the re-assembly of my 1600 so this is a hot topic for me!

I have always run VW's on and have always run them on 20/50 mineral oil which seems the ideal choice of many.

Last time I was doing any serious VW flying (in a Taylor Mono) we used Castrol CRI 30......with no problems at all.

The air-cooled VW fraternity seem to favour straight 30 all the time as far as I can see.
Morris Oils of Shrewsbury do a straight 30 of good quality which is what we've been using in the Evans VP1's 1835. Too early to say much about it with only 5 hours or so on the engine except that the wee beastie seems to start fine from (sometimes very) cold and from warm/hot, and seems to hold good oil pressure and temperature at all times.
I sourced the Morris oil from an aircooled VW specialists (Kingfisher Kustoms in Birmingham), but agricultural suppliers Burgess's are an agent for them and have supplied me with heavy (EP140) gear oil and straight 40 oil, albeit in a pack of 4 x 5 litre cans. (I sold 3 of the EP140s on!)
I use the straight 40 in my Morris 8 and have done for a while.

Rob Swain. The Morris 8 engine is also used in the early Minors. I've got 2 1940s Minors running on many of the same bits as the VW engined FRED. The sparkplugs used on the military version of the Morris 8 engine are shielded like proper aircraft plugs and are the same dimension and heat rating as the B6HS plugs recommended for the VW. A trip to a Tank museum (Bovington?) secured a pile of new dimantleable plugs and leads.
