Marvel Mystery Oil Question "Judson SC ?"
VWFREAK - February 13th, 2008 at 01:49 PM

What other oil can bee used instead of this product in Judson Superchargers etc. I believe any mineral based SAE 0w - 20 or 30w will do, but not synthetic or blended oil?

I'm basically looking for a readily available ( Autopro / super cheap etc) product instead of having to import or spend a fortune on some oil no ones heard of.

Assistance and opinions welcome.

Thanks
Peter / Bones

I think Dave Birchall will confirm this - on Dave's suggestion I use ATF and it works well. It is also the same colour at MMO so in the bottle it looks same. I have some real stuff and it is a little thinner than ATF and smells a bit like ether (nice). The other alternative is any upper cylinder lubricant - Techron, Redex, Morey's or yr Ampco oil. etc.

Are these oils readily available in Australia, Techron, Redex and Morey's ?

the oil needs to be combustable as its fed into the fuel mix to keep the vanes lubricated so u cant just use off the shelf oils but im sure there would be some alternative around

like said about speak to birchall

taken from a judson info site

As the vanes need to be kept well lubricated, oil is fed to the inlet manifold of the Judson from a glass container filled with engine oil. This oil is drawn into the supercharger by inlet vacuum and, after lubricating the vanes, passes into the engine to be burnt along with the fuel. Judson claimed this helped engine longevity by acting as an upper cylinder lubricant.
