Hi all, another quick question. I'm gearing up for the first oil change and I've got a new silicon pan gasket and I'm almost ready to go, but I'm not sure which oil to use. The PO said he'd been using sae 70w mineral oil, but that seems a bit heavy for summer use. I'm thinking about buying some Castrol Classic 50w, it's a bit pricey and needs to be special ordered. Any thoughts on other brands/weights/sources?

Thanks,

Duncan

Sorry, I should have added that the bike is a 62' /2 with just over 20k on the engine.

Ask 5 BMW owners and you'll

Ask 5 BMW owners and you'll get 7 different answers!!

The key thing you want is an oil that has an API rating of SG. This means that oil will have a generous supply of ZDDP...this compound is needed for the older flat tappet engine.

As for weight, I think owner's manuals call for 40w in summer and 30w in winter. Yeah, 70w is way too much...I think 50w is also too high. I'm using BMW's 10w40 pretty much year round, but I live in south Texas. Spectra makes a good mineral based oil...they also have a good semi synthetic. Valvoline VR1 rates high in the ZDDP category.

Thanks again!

Only downside I can see is I

Only downside I can see is I won't get the cool oil can that the Castrol Classic comes in... I guess some sacrifices need to be made though..

Was that Castrol oil going to

Was that Castrol oil going to come in a metal can? As a related note, Porsche came out with a "classic" oil which didn't provide much in terms of API rating, etc. So a friend of mine had it tested. It was kind of middle of the road. The interesting thing was that there was an elevated ferrous level to the oil. Doh! It comes in a can. IMO, plastic is better!!

Delo 400

Chris Betjemann of Barrington Motor Works recommends Chevron's Delo 400 - SAE 40. You can buy it by the 3 Gallon case from NAPA for about $55. I asked Vech what he thought about this oil and he said, "That's a great oil for diesel motors, so it's a great oil for all vintage BMW motors." If both of these guys like it, it's good enough for me. I like that I can use it front to back in all my pre 70's bikes. I called Chevron to verify its levels of ZDDP and they were spot on. (They also make this blend in 30 weight for you colder climate riders)

"Delo 400 heavy duty motor oils are mixed-fleet engine oils recommended for older four-stroke diesel and gasoline engines. Formulated with advanced additive technology, Delo motor oils provide excellent control of deposits and sludge, minimizing oil consumption and optimizing engine overhaul intervals."

The importance of the appropriate oil for these bikes is just as important as the frequency of oil changes. I try to keep my intervals somewhere between 500-1000 miles.

My problem with an oil meant

My problem with an oil meant for a diesel engine is that the environment for diesel and gas engines are so different. They operate in different temperature regimes so right there, I wouldn't think it would be compatible. Their ad copy suggests it's good for both types of engines, but I have my doubts...being the non-petroleum engineer that I am!!

Castrol 20w/50 for all my airheads.

Have a question.
If multigrade oil existed in the 50´s and 60´s would car and motorcycle makers have used it for their air cooled engines?

PM. I hate auxiliary verbs.

I did...

I used Castrol 20-50 in my /2s for more years than I care to remember--probably over 30 years. On my present '67, I switched to Amsoil after I had some preventive maintenance done on the engine (slingers), and then more recently followed Vech's suggestion to use Valvoline VR1.

Hi, I think it is easy. I

Hi, I think it is easy. I suppose for BMW R12 and Zündapp KS 601, BMW R 51/3 etc, "Millerol M40_ Unlegiert"
Make no compromises, you can use it for engine and transmission!

If but a compromise

"Castrol Motoröl Classic XXL SAE 40"

Ake only mineral monograde and unlegiert and you'll always be happy!

The ELF oil seems like it's

The ELF oil seems like it's OK...the API rating is SH which is slightly degraded from SG. As I understand it, Europe doesn't really buy into the ZDDP discussion as much or didn't get on board as soon as the US. Europe has a different rating system for their oils.

I ran in the rebuilt engine

I ran in the rebuilt engine with Joe Gibbs 5-30 break in oil (300 miles) and then switch to Bell Ray 10-40. I have always had good luck with them. I also send out a oil samples to Blackstone Labs for analysis, that will tell you all you need to know if your oil is doing it's job.

Cheers,
Jim
