The oil recommendations are climate dependent. Here in Texas I like to use 40w mobile + 1 gallon of Lucas oil stabilizer. If I lived in colder weather I would use 30w or in very cold I would use 10w30. A lot of people use Rotella I just prefer Mobile both are good. I would always recommend using 1 gallon Lucas at every oil change regardless of the brand of oil. You will want to be sure to use high detergent oil. It will last longer

Frequency of change is more important than oil brand.

I use Rotella, but then my Daughter works at Advance Auto, so I get a considerable discount. One thing about synthetic.... I had a Buell motorcycle and had rebuilt it verry time consumingly and perfect. All was good, NO leaks as I took my time in that area. I went to the dealer and wanted to change all the oils before taking a trip from So. Cal to northern Utah (730-ish) miles. I asked the mechanic about running Rev-Tec synthetic, and he said "If there any possable leaks, they would appear useing synthetic" So I'v always taken that to heart on less refined motors. However I did use Mobil 1 in the Vette always with no problems ever.

Rotella 15W40 with 2 QT Lucas oil treatment. So far very happy with oil pressure building and cold weather cranking.

Use any good name brand 15W40 oil. I have used Rotella, Mobil Delvac, Pennzoil, Valvoline, and others. I buy what's on sale as long as it is a good name brand. If all else is equal, I like Rotella, Delvac and Pennzoil in that order.

I use Chevron Delo 15W40 in our Deuce and in our farm tractors and have had good luck. That being said, I also think the Shell Rotella 15W40 is an excellent choice.

John Deere +50 in my Deuce and John Deere 5520 and 4600 tractors. Never a problem and very low oil consumption

I use Delo 15W-40, but I would go with any quality diesel rated 15W-40.
My first M35A2 had 15W-40 stenciled on the underside of the hood so you could not miss it when the hood was up.
