How many hrs with Premium Plus oil

[Toffen]

Hi!

I am currently breaking in my two rebuilt (bearings and rings) Merc 2.5 EFI SS engines. Iam using Premium plus oil. Shall I use this oil for the entire 10 hrs break in period. I am now in my 5th hrs.

Cheeers and thanks, Toffen G

I would and I also put a little extra in when breaking in mine. Your only a good day away so may as well keep it simple. It probably doesnt matter much but better safe than sorry. Why buy the way do you usually run a differant oil? James

IMO Thats PLENTY of time on the blends before you can upgrade to a full syn oil if your engines are ALL Nic coated bored .

BTW :I NEVER over oil an engine at break-in as the ECU's are designed to "work" at the prescribed oil ratio that the factory set the processors up to funtion at.. Over oiling causes extra heat and a lean fuel ratio due to the thick viscosity this thick mix creates, its common sence ...( what goes through a funnel quicker syrup or water the thicker mix WILL pass through the metering system be it either a jet or an injector with the same fuel pressure SLOWER thus the end result is LEANER )...

good luck Toffen, Cold up there yet ?

Hi!

Good to hear from you Jay!

Here up in north the summer has been awful. Its still only 15 Celcius and it has been raining loads the last two-three weeks. There has not been so much rain in 60 years... So thats partly the reason why I have only been on water 5 hrs. The gas prices is now over the top too... USD 2,5 per litre / USD 10 per gallon...

BUT, running over the swells in 80 mph is still bigger than life.

Consider to buy a new boat next year; see enlosed picture. 92 mph with a Merc 600 Sci..

Cheeers, Toffen G

I run the preium only. JUst over 19 oz. to 22.5 litre, Its not worth take the chance.. This mixure is for running mid to hig RPM'S.. If you run lower rpm reduce the oil(if you do this do not run high rpm
