I'm using a straight 30W mono grade mineral oil in the Model T, because T's don't have an oil filter it's important not to use any oil that contains a detergent, so the crap stays in the oil (http://mkb-cc.yanksrule.co.uk//Forum/smileys/wink.gif)
Straight 30W is also the only way to ensure that the transmission linings remain lubricated even when the old Gal is cooking in traffic (http://mkb-cc.yanksrule.co.uk//Forum/smileys/wink.gif)
However this presents a real problem when trying to start her in the winter, the oil is so thick it's hard to get the engine to even hand crank over (http://mkb-cc.yanksrule.co.uk//Forum/smileys/down.gif)
So a suitably low tech solution has been devised (http://mkb-cc.yanksrule.co.uk//Forum/smileys/chiny.gif)
Starting with a gallon of finest Paraffin :

Then the motor spins freely (http://mkb-cc.yanksrule.co.uk//Forum/smileys/up.gif)
NB : Make sure you have no fuel leaks before you try this and the garage door needs to open (hence the brick wind deflector) because Paraffin burns dirty !
Probably best not to mention you do that to your insurance company . . . (http://mkb-cc.yanksrule.co.uk//Forum/smileys/wink.gif)
