Default Re: Detergent oil

Don't use synthetic oil ! It will leak from every part that leads to the outside. It's far to slippery for your antique engine to handle. Regular Rotella oil 20w-50 is just fine or any diesel oil will be just fine. It can sit for years, but any oil while sitting will just migrate into the pan, that's why it's best when sitting for a long time to pre-lube through the distributer shaft. I run MMO in my fuel on all older engines, have done so for many years and swear by this practice. Some frown at this, but I have never had a valve problem. One of my friends has a Ford 9n tractor, the valves hung up from the modern type gas, I freed them up and got him started on MMO and he has not had any problems with the valves in the last five years.
