I received the email below from a relative helping to restore an antique fire truck.
Our fire department is restoring a 1923 Seagrave pumping engine.
It is powered by a 6-cylinder, "T" head gas engine displacing 1720 c.i.
We have found a copy of the lubrication manual from that era.
It was prepared by the Vacuum Oil Co. of New York in collaboration with
Seagrave.
They recommend "Gargoyle Mobiloil" grades A, B & C for the various driveline
components.
Could you provide the current equivalents to these lubricants?
Any direction or information will be greatly appreciated.
Thank you,
Monessen VFD #1
In my research Type C is the currently available 600W, however an equivalent to Type A and B eludes me. I know Type A is recommended for winter use and B for summer. The engine has been completely rebuilt so sludge will not be an issue. The flat tappet design may be an issue with new oils with reduced ZDDP. I contacted TechSupport at ExxonMobil with no results. I was thinking of Rotella 15w-40 with a break-in additive. Opinions and data would be appreciated. Thanks
