I have a Kawasaki FH430V 15 Hp 2 cylinder engine in my Cub Cadet lawn mower. I would like to add an oil pressure gauge but cannot find any information on this engines normal oil pressure range. I checked on www.kawpower.com and on the internet. There is no information on oil pressure in the owners manual either. Anyone know what the normal range should be? I was thinking about going with a 1 1/2" 0 to 60 psi mechanical gauge.
