Engine Oil

RockRon · Feb 2, 2010

I'll probably regret asking and I apologize if this is a new version of an old question, but... The workhorse on our farm is a 1972 Deutz D4006, diesel engine, air cooled; the usual for Deutz and all around great tractor. The owner's manual calls for 30W engine oil above 68 degrees F (converting from C), 10W below 14 degrees F, and 20W20 for everything in between. Wouldn't 10W30 cover the entire range? What would you do if it were your tractor?

15w-40 year round. Rotella, Delvac or an equivalent

Hi RockRon: There is another reason I am switching to Rotella T and that is the big reduction of Zinc in most other brands of oil. I added a link to one post about it. Another comment is that there is a 10w-30 in Rotella for colder weather. Oil can be a hot button topic so I'll stop. To each their own. Google the topic. ag
Much less Zinc in most oil
