Westerbeke diesel oil
« on: September 24, 2020, 04:48:31 PM »
Hi folks,

Starting to prep the boat for winter, and was out shopping for engine oil but having a hard time finding the right stuff.  The PO specified "Castrol SAE 30 Diesel", but Canadian Tire does not sell that.  All I could find there were synthetic oils marked as being for diesel, but I'm reluctant to go with that.  Closest I could find is Penzoil SAE 30 , but the container does not specify whether for gas or diesel.  Does anyone know if this oil would work for the Westerbeke?  Of course, when I asked the parts guy he assured me that any old 10W-30 would work, but I don't know....

I use 10w-40 due to hot conditions that are usually present while underway. After many years, no problems.    Also, if you use antifreeze to winterize, from personal experience, do not use the premix to suck into the cooling side as there is already significant water in there.  Use the concentrate.

I have been using shell totella t4 15w40 for the last thousand hours in my w21. Seems to be a good oil. I've not noticed any change in the engine performance either way over that time. She just runs.
I have run at near freezing conditions for weeks as well as very hot with no variation that I could detect.  Oil pressure is always the same.

The manual specifies different grades depending on expected operating Temp.
See the manuak for details.
