I have a 1967 John Deere model 60 lawn tractor I am somewhat restoring ground up. When I purchased the mower the original Tecumpseh engine was locked up but knowing cast iron blocks it should have been a peice of cake to rebuild. Well after I tore the entire motor apart it just wasnt happening. And to find a replacement, well... that isnt happening. So with Hours and weeks of research, reading, and measurements, after joining countless facecook pages and reading forums and asking questions. So many people just simply said that its not possible. Well I found the new heart of this bad boy. Honda! I have mocked up and somewhat installed the engine and it will work fine. I am still in the process of tear down, cleaning and painting parts but very soon I will be putting it back together. My stepdad and an old timer i work with says the honda motor has [censored] the John Deere, but I simply replied "John Deere sells Honda". Also many came with Kawasaki engines... anyway. I hope to finish before anyone catches wiff and beats me to it, but I may have the only 1967 JD Model 60 with a Honda engine in the world!!! My question is: I am going to break the engine in with SuperTech 10w30 lawn mower oil. Run for an hour and change to ? Whats a great oil for a lawnmower engine? Ive been using pp in my cub cadet and has worked flawless. But i want this sucker to last. The supertech lawnmower oil API SJ. Amzoil has specific lawnmower oil for "splash lubrication", are the two any different than running any other conventional?
