So I have a 1990 JD 318 with the 50" mower deck. Love it. I am new to working on small engines, but learning. This past week I changed the oil and filter. When I filled it back up with oil, I filled it slightly above the full line on the dipstick. I let some oil out till the oil came right...

I read the technical manual it shows 7 pints (3.5 qt.) and when I put in 3 qts it was overfull. I changed the filter and drained all I could out of it. Seems strange that it only takes like 2 quarts. I don't have the operator manual does it say anything different?
