Re: 150 johnson
Well, engines burning premix never lose lubrication, Mtribute, but engines with working VRO or oil injection sure are convenient.
Want to add 2.75 gallons to the tank? How much oil to add? VRO doesn't care, it just keeps the mix correct. . . as long as it is working correctly.
The convenience of oil injection comes with some risk, the security of premix comes with some inconvenience. You take your pick and pay your bux.
I am going to disable the VRO on my '88 Johnny 60, but only because I can't find a good place to put the oil tank in my 15' boat.
