Yanmar 2610D Transmission Sound

You mis-quoted, we were talking about 15W30, not 10W30 that is normally used in regular gas engine vehicles.

As for 15W30, it's rather a newer configuration. Chevron holds the patent on it. Guess if you want to use it, pay the premium price.

As for the oil viscosity, it's best to go to the experts ...

yea I noticed that once I posted. I just let it be cause if I wanted a 15w30 diesel I may as well use a 10w30 diesel which is made I believe.


And I still stand by my comment that 15w40 will be thinner at start up than straight 30w oil.
