For years Cat has strongly recommended it's Special Application Engine Oil (SAEO) 30W, rated CF-4 to be used in 3116 and 3126 engines exclusively. Now they have discontinued this oil and are recommending using CAT DEO's 15W-40 or 15W-30 and they are saying, get this, you can only buy it from Exxon Mobil. So it's probably Mobil Delvac. I can't get anyone at Exxon to respond so far as to where is buy it..
My CAT mechanic and a well known Cat engine surveyor said we should stay with 30W, so I am hesitant is using multigrade oils many of which are synthetic blends. For years Cat recommended against multigrades. I know some people uses Rotella T1 30W but that is only rated CF-2. Amalie motor oil has XLO Fleet 30W again rated only CF2. They do have XLO 10W-30 rated CF-4 but Amelie can't tell me how to purchase either. AMSOIL is recommending their Signature Series 1W30 synthetic blend with a superior CF-4 rating but its over $40/gallon now and i am still not sure about the multi viscosity issue.
What are people using using in their 3116 or 3126 engines now? There are still a lot of them out there.
I am attaching the memo from Cat about this. My dealer is of no help. But I bet TF members have a solution.
