I have just picked up a 1975 T3 Cali. It's a tractor engine and fully synthetic is wasted on it. Whats wrong with 20w50 mineral oil a la BMW airheads and other simple aircooled engines from the same era?

Yup.

Anything "better" and she burns or spits it out.

Just change when it's dirty. Do the filter every other just to check the crank is still there!

Fluff.

New Guzzi's like my Norge are using 10/60 synthetic, BMW hex heads have just started using a full synthetic 10/50. Guzzitech have some bikes with huge mile ages, before synthetic oil became a must have. So, do the research and decide.

My 78 LM2 leaks from the alternator seal with synthetic. Doesn't with standard 20/50.
Guess which I use!

Mine did that too,

Not a drop on 20/50,

I use fully synth 20/60 in my 1978 cali..

What was the engine designed to use? 20w50 mineral. (SAE Sf - Sj I would guess?)

So use that and change the oil and filter more often.

Sorry mate, the engines were designed when mineral oils were in use, not for mineral oils. If you want maximum lubricity, then use a castor based oil, but you're on your own when it comes to changing oil and having to flush out the engine every time!

Let's not forget that mulitgrade oils were only just beginning to be accepted when these motors were designed, so as lubrication technology moves on, then why not use it? Don't forget that oil doesn't just lubricate, it helps to disperse heat too. It's up to you if you want to be a dinosaur, but for me, if there is a better oil available, then my engine deserves it.
