Default Re: Differential oil used

The 600 w steam engine oil stays on the gears. Long chain carbon molecule.
I plain 'O say 600 w oil is just too darn thick to flow past any seal.
Well not really but go with it.
It's like leakless oil :-}

Have you actually done the screw driver test with STP? Dip the smooth metal end into STP, you can not hold on to the sinking smooth shank of the screwdriver between your fingers. It is the same for the 600 W oil.

I just use that 600 W oil from Bratton's. It's not 600 wt but may be an oil used in steam engines when 'T's and 'A's were young.. Anyway the 'transmixer' works just fine for me, for a 'crash box'. Both up shift and down shift. I mean how much better can one lube this thing? Same oil used in the rear axle, and steering box. Two quarts will last you years. 1-1/2 pt needed for the 3-speed.

I don't need any Scientifically Treated Petroleum from Andy Granatelli's company. I only use these long chain carbon molecules when I'm assembling and building my churns prior to start up for the first time. Often on the race engine I'd pull the distributor and spin up the oil pump with an electric cordless drill that came from Ed Pink's shop for oil pressure before making spark.
