6C8.3TA Normal Oil Level

[Ron Carter]

I recently bought a boat with these engines and the engine surveyor commented to the seller that the oil was at the low mark. The seller commented that it was supposed to be at the low mark, whereupon the surveyor replied “You must have been listening to Tony” .

The engines are 2002 model with 700 hours, mostly in fresh water. They have zero blow by. All coolers, BTW, have been serviced the “Tony way”

For some reason, I feel the urge to add a quart to each one.

I read a Tony’s tip on oil levels and did not interpret the advice the quite same way the seller did. What is correct?

I have received more information from the seller and learned the engines have exactly amount of oil that Tony recommends.

Closer to low than high.

[Ron Carter]

Yes, this is what I read. Between the lines I perceive that you think running at the low mark is OK?

I see no issue in adding a quart if they are at the low mark (especially if it helps you sleep better) but I would also plan to do an oil change and take note of the # of quarts for LO and HI.

This is what you read, right?: https://www.sbmar.com/articles/oil-pan-capacities-for-cummins-marine-engines/
