Good day all.
I have a Glasstron powerd by a mercruiser 2.5 120HP @ 4300 RPM.
A perfect running engine, propped correctly.
The duty cycle.
Some plessure trolling, some water skiing, some full throttle cruising.
I change oil and filter every year ( about 50 hours ).
It is used 9-10 months a year temprature varying between 2c and 30c or between 36F and 95F.
The placerd says monograde 30 api se.
Till now i alway's used a hdeo 15w40 ( rated ci4/sl )
Zero oil consumption.
Seems pretty thin whem comming out.
Afther going true some UOA i was stunned by the shearing of multigrades in marine inboard engine's.
Considering going to a monograde.
I have lot's of briggs and stratton OEM oil Available.
It is a monograde 30 rated API SJ/CD.
I cannot find a PDS on this oil so viscosity @ 100c is unknown.
HTHS is unknown
The goal is to achieve long and healty engine life. engine is alway's allouwd to warm up and cool down before and afther hard work.
I guess there is soms fuel dillution going on, as these engine's are know for like the 3.0 140 engine.
How do you guy's think the briggs and stratton oil will hold up?
Is the monograde 30 good enough?
Thank you and please pardon my english.
