CJ4 oil article
it mentioned how CJ4 is fine to use in older engines and how they added additives to the oil to replace the missing sulfur....
one of the most interesting this is that sulfur actually breaks down the older oils resulting in loss of lubrication....which seems to me to be kind of a double edged sword
check out free trade magazines, often have real good info compared to barnes and noble type magazines for people who are looking to keep their engines running not just buy a lift kit
