" I have been getting conflict

" I have been getting conflicting numbers on these 2 things.I have been told 50 to one ,but some say 24 to one .The cover on my engine says 1 quart to 6 gals,that would be 24 to one,but the guy I bought it from ran 50 to one .He used a j4c plug,napa says j8c for that motor,and Joe says J4 or j6 but not j8.I have all 3 sets and will run the j6c.Would running 24 to 1 run badly in a motor that needs 50 to one,other than wasting oil will it cause any problems?Thanks Mike "
 
"I agree with Joe. Run the J4C

"I agree with Joe. Run the J4C or J6C, or use an NGK B6S. Your motor is safe to run at 50:1 using todays TCWIII rated oil. But, do use a major brand, like OMC, Merc, Yamaha, etc.

" Thanks Daren,I have the j6c in there and it ran for the last 2 owners with 50 to one so I dont see any reason to change,Joe sure seems to have alot of the answers here and I appreciate the help he already has given me . Mike "
