Is there anything to the companys who advertise oil for old iron engines? does anyone here use synthectic? or does everyone just stick to the basics,not including wieghts and viscositys are there better oils for older engines,I'm nearing the end of a rebuild and exploring this subject.any feed back is always great.thanks |

I think everyone has their own opinion on this subject. If your going to work the engine in a boat then you might want to get advice from the guys that run boats all the time like JB, Miro, etc.. If the engine is going to be run for show then I don't think it will be as critical. For show engines I run 30 weight non detergent in the drip oilers and also mix 2 cycle oil regular or synthetic in with the gasoline at a ratio of 100 to 1 just as a slight precaution to help with lubrication. Works good for me. Engine smokes just a little. If I was to run my engine in a boat I would probably increase the amount of 2 cycle oil I mix with gasoline to what ever the boat guys are using. Some of the guys are still mixing 30 weight non-detergent with their gasoline which seems to work also. So I guess it is really up to you as what you want to do. If you do a search on this forum the subject of what oil to use and how much has been talked about a number of times already. Good luck.. |

I'd run a slightly richer mix of oil/gas - say 1:30 for the first hour or so of running, to make sure there is good lubrication after the rebuild - some folks go even richer down to 1:25 for a newly rebuilt engine.
After that period, you might find that a 1:30 mix is good if the engine is in a boat.
I don't believe that synthetic oil would make any difference since these engines are not high speed or heavily loaded and have rather large bearing areas for their horsepower compared to today's 4 cycle automotive engines.
