I just received a 1913 Speedster. Seems to be an incredible build, everything looks new, but zero documentation - I will be asking a lot of questions. I am mostly an old car guy, Packard, Pierce, Thomas, Napier, Cadillac. I recognize that Model T, I have several. It is a very tough car, but unique in many aspects. I have studied the history and lineage, but, now "hands on" and would like to do it properly.

First, Oil? I use 15w/40 heavy duty diesel oil in my brass cars. Is this be well in a Model T? I drained through the upper petcock and got an almost 3/4 full glass mason jar. Obviously over full!

Second thinking about adding a sight glass on the lower petcock? Are these recommended? Looks like a very good idea. I plan no off-road touring! It could otherwise be ok?

Third, I have a new KC Warford and a Ruckstell axle. What grease/oil?

My engine block has the number 50 36 59. This seems to be 1914 or 1915? I am less interested in whether my car is a 1913, but more so as to what year parts fit it. There does seem to be a range from '08 to '27. But where and what.


I am compiling a library of Model T books. Have not tried to start the speedster. I am starting with oil and grease.

Bill, you will get a better response on if you post this in the general forum. I know the 'what oil' alone will create quite the input. I , personally, run 15w40 in everything I own.
