First of all, if you decide to do this, YOU have to accept responsibility for it. DON'T blame ME ot the oil company. Folks have written to oil makers, and been told it's NOT recommended. IMHO, the oil companys say this so as not to have every leak and problem that EVER happens to a 50+ year-old machine blamed on them! IF the engine is badly worn, or has leaky seals or gaskets, it MAY use/burn more oil as the synthetic will tend to clean up carbon, crud and gook that have built up, and may be sealing the piston rings in their grooves, and the gaskets and seals. They will tell you the seals and gaskets will be DAMAGED by the syn oil. Well, the gaskets don't give a darn, and the rope seals on the crankshaft won't be affected one bit, EXCEPT built up varnish and crud will be cleaned off, possibly making them leak, IF they are already "bad". If the engine is in good shape, no excessive wear or leaks, or massive sludge buildup in the crankcase, it will LOVE the synthetic oil. I run synthetic in several old vehicles and tractors for easier starting in COLD northern ND, and have NEVER had a problem or complaint.
