So I am the only one who does oil analysis around here?
JDude,
I do used oil analyses, too, using a company called Blackstone. It costs about $25 per sample. I've found no appreciable advantage in using synthetic over conventional oils in my 4610, so I simply use Chevron Delo 15W-40. Frankly, just about any name-brand oil will do.
If I were operating in a colder environment, I'd consider a conventional heavy duty engine oil such as Chevron Delo 10W-30 or a synthetic 5W-40 or 0W-40.
Cheers,
Mark
