Guys,
Would it be a smart idea to add oil to the gas when breaking in a Merc
Optimax (200 HP SportJet)?
Merc' manual says NOT to add oil during break in. Is this because of
environmental laws and such or would it do any harm to the optimax
system?
I would say running a little more oil during break in cant hurt? Is it
recommended to add oil? If so how much should be added? For how many
hours should oil be added?
The manual indicates the break in period is over after 4 hours .. that
seems awfully short ... whats the deal here? What is recommended to
do?
Does anybody have knowledge for that?
Matt
DoNOT add extra oil in the gas!!! The Optimax is a direct injected motor and
none of the extra oil would touch the crankcase, bearings, rods, pistons,
etc. This is not a traditional 2-stroke engine. The gas is injected directly
onto the top of the piston and is quickly ingited. Any oil in the fuel would
form extra carbon on the piston and not do the motor any good at all. Read
up on the direct injected motors and follow your owners manual..
