Reply To: 1925 Series 80 oil level??

[Peter Williams]

Tom,

On the passenger side of the oil pan there is a stopcock.

Open the stopcock and if oil comes out, the engine has at least sufficient oil.

If not, then add oil until oil comes out of the stopcock.

Do not mistake that SIDE stopcock for the DRAIN stopcock, which resides at the bottom right of the oil pan.

I believe that the Series 80 engine takes about 9-quarts of oil.

A bit more is fine.

Use Diesel Grade oil.

Good luck.

Peter
