Having worked on the propulsion system of the 757 while the airplane was in preliminary design all the way through it"s certification and entry into service, I feel somewhat qualified to answer your question(grin). The oil you select is dependent on the ambient conditions you operate in. I live in Western Montana and we have some cold temps in the winter. I tried 15W40 oil because that"s what my diesel tractor uses and I wanted to try and use one grade of oil in all my tractors. It made my TO-30 a bit harder to start when it got below 20F so I switched to 10W40 and it works fine as a year round oil in that tractor. If you live in a moderate climate where the ambients seldon get below say 20F for long periods of time then maybe you can use 30W, or even 15W40. Certainly 10W30 and 10W40 will work in almost all but severe cold conditions where you might have to switch to 5W30 in winter. Use 30W in the air cleaner cup.

Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
