I have been doing a lot of reading on the proper oil to put in my 3116 Cats, I am unclear on exactly what oil I should be using for the Great Lakes region.
2000 400 Sundancer with 350 HP 3116's. The prior owner used 15W40 but I know from prior experience that a straight 30 or 40WT should be used.
I want to change the oil to either the CAT SAEO or Rotella T1 straight 30 or 40. My question is, for the Great Lakes region, should I use 30 or 40? Temps in the spring can be in the 30's easily although not used often in that temp.
