Ive got an integral garage in the house and 
run a J2 on Castrol R. There is no 'cold 
engine' smell to speak of. When the J2 
suddenly lost all oil pressure due to an 
air leak at Prescott last year I ran the J 
for a considerable way before I noticed it. I
suspect that without Castrol R I would have 
run the bearings but the engine (rebuilt by 
Bob Jones) is fine. 
And you are surrounded by
that wonderful aroma as you drive along.On
