I own a Mainship Trawler (boat) that is powered by a CAT
3116 TA 300hp engine. CAT insists that the engine oil
MUST be a straight wt 30 or 40wt. Seems polymers have
a tendency to clog up the turbo and aftercooler in these
engines leading to engine problems. So I use Amsoil
30 wt heavy duty synthetic diesel engine oil with a Amsoil
remote oil filtration unit. Oil capacity is almost 30 qts.
Engine runs like a watch with no problems in 675 hours of
operation. The issue is that I burn/lose about a quart of oil
every 15-20 hours of engine time. I don't think this is normal.
The engine does not smoke or leave any residue of any kind
on the transom. I do run for extended periods like 8-12 hours
but do not exceed 2300rpm which is conservative operation.
I was/am considering either going to a straight 40 wt or adding some kind of additive to the oil. I am somwhat reluctant to add anything to the oil but I am not aware of any straight 40wt diesel
engine oils, preferably synthetic that are out there.
Please advise.
