So your statement was off by a factor of 10! I would never have guessed that Ford recommended such long intervals.

Interesting. Both my Model A and the 34 don't have oil filters. I'm pretty sure the owners manual for the Model A stipulates 500 mile changes The Model T owners book certainly did but of course the oil went through the transmission as well. . I can't put my hands on the 34 owners manual but I think that was 1000 miles . I did find the owners book for my 34 Plymouth and that was 1000 miles in winter and 1500 miles in summer and that had a filter ! All pretty academic really because the oils today are probably 20 times better than in the day ! I actually don't mind changing the oil every 1000 miles or so . Maybe I could go longer but my runs are pretty short mostly round town And the oil seem to get pretty dark after only 1000 miles . Can't see more frequent changes doing any harm other than to my pocket and if I was worried about that I'd be driving a rice burner ! -Karl
