I changed over to synthetic oil in my already old 3000 hours plus, the hour meter broke twice, engines and I couldn't be happier. I use Mobile Delvac1 which is 100% synthetic and has diesel additives.
It did three things immediately. 1. the cold engine smoke reduced at least in half. 2. the oil sheen on the water from the exhaust reduced a real 75% or more and 3. my temps dropped 5 degrees on each engine.
This was probably in 94 or 95 and I was on a forum that every one told me I can't use synthetic in an old engine, in a Ford Lehman, because it can't have a multi-weight, etc.etc.
I have used Mobil 1 since 1977 in every engine I own and I use a 2 stroke synthetic oil in my outboards too. It's biodegradable.
So after four years of using fossil oil in my boat I made the change over. I now change oil every 200 hours instead of the 100.
Another improvement is I have the canister style oil filters, not the spin on. When I was using fossil oil with 100 hr change intervals, there was always a heavy thick coating on the bottom portion inside the canister. I had to not only spray a cleaner on it I had to forcibly wipe it with a rag. It was thick and hard whatever it was.
Now when I change the filter the canister is shiny inside. It took a few changes to clean up the engine but now it's clean when I change oil. My oil consumption is less too. I think the carbon buildup in the iol rings cleaned up and that ring works properly. Just my guess.
I'm interested in seeing other's stories with synthetic. Please post them.
