1930 Century 6 oil question

Hi Everyone,

i have a question about what oil to use in my newly rebuild 1930 Century 6 engine. I have the stats on how much oil the engine takes, but can't find anything on which "type" of oil. Can someone give me a little insight?

thanks,

David

Question, did you clean all of the engine of all the old oil? If the answer is yes. Then I would use a 20-50 detergent oil. I have 20 thousand miles on my 1936 Huppn and that is what i used after i rebuilt the engine. The reason people do not use a detergent oil without a rebuild is that a detergent oil will clean all the slug out of the engine and clog the screen in the oil pan. When this happens, you will kill the rods bearings , which are made of babbit.

Thank you for the response. Yes. We did a complete rebuild and re-Babbitt. We hope to test the engine in the next few weeks.

Ok, before turning on the ignition key. turn the engine over & make sure you have oil pressure, then give it the spark.By the way if you are not a member, we have a great Hupmobile Club. Good luck, Huppingly Yours Chuck.

On a new rebuild I think 10-30 would oil better with the tight clearances. If you can find 20W non detergent oil I would use that for the first few hundred miles to aid in break-in.
