I see that everyone uses 20w-50 oil(mostly Castrol). The owners manual recommends straight 30 weight- This is confusing- I assume things have changed over the years-


I remember reading an old interview with a Porsche engineer many years ago that asked why Porsche was recommending straight weight over multi-weight. The engineer said at the time, multi-weight was fairly new and didn't have enough track record for them to feel comfortable recommending it at that time. Simple as that and they obviously got comfortable with it as time went on.

FYI, After reading through all the comments, talking to an experienced european mechanic and doing some research online to find a suitable engine oil for my 1970 914 I settled on Lucas Hot Rod & Classic motor oil with high levels of zinc, molybdenum and phosphorus needed for older car engines. Also it's readily available via Amazon, Summit Racing, etc at reasonable prices. It's not Brad Penn or Castrol (Old go to) but I've had very good results with Lucas products so I think it'll do.

Didn’t know they made a 20W-50, but have used their 306 10W-40 and like it. Just scored a good deal on a case of Joe Gibbs Racing Driven DT50 and am looking forward to using that- don’t think it gets any better than that for a type IV.

It works well and a decent price point.

Anyone use the Driven products. I need to do an engine and trans oil change and was thinking about using their stuff since they sponsor Octeenerfest.

I am going to try Mobil 1 15w-50 synthetic soon. It is readily available and I like the idea of it being synthetic. It also has large amounts of zinc, many people on the pelican board like it as well.
