I remember reading on the gene berg site that in air cooled cars the oil is used to soak heat from the heads etc and take it back for cooling. They recommend traditional oil for this reason.

Ask your engine builder. He should be able to recommend a 'preferred' oil based on engine internals (clearances, cam and lifter sleection etc etc) set up in the engine

Big bore, loose clearances = thicker mineral oil (usually)

I remember reading in my Gene (craig) manual that only natural olive oil will lubricate the entire system properly. It is a delicate balance, friction in the system not only causes premature wear but nasty little noises, or so my misses says...

Oil technology has come along way since Gene was promoting his (mis)information

What oil do you run in the 1916 Glen?

VWCOOL - October 30th, 2005 at 05:46 PM

GTX2 in everything - 1916 and my V8s. Cheap, does the job (used it for 15 years and had analysis done a coupe of times - all good) and u can buy it anywhere. I change every 2000 miles in the older cars (not much use) and every 5000km in the daily driver. I think my mate Macca runs GTX3 in the WRX powered Type 3

I second that.

Personally I use castrol synthetic 25w50 in my 1641 turbo engine and the 2332 uses 15w30.

The 2332 has close tolerences. I don't know about the 1641 as I didn't record everything during the build process for that engine.

The thing is that the lighter the oil the less oil pressure you will have, and you need about 1lb per 100 RPM. ie 60lb pressure at 6000 RPM.

If your engine tolerences and oil pump can handle maintaining the oil pressure then run the lighter oil.

As far as heat transfer goes synthetic is more effient than mineral based oils, but seriously who cares so long as it lubricates.
