The only info I have on this engine is it is a 1980(?) Chrysler 9.9hp. My brother-in-law kept it when Gram passed away, couldn't find books of it. He says 1quart to 5 gallons but I just wanted to be sure because a friend of ours just bought it and I don't want it to screw up on him.<br /><br />Hopefully someone can help, if not...thank you for your time reading this post!
