What oil to use

[jmoorepghpa]

Since marine 4 cycle motors run at wot a good portion of the time is one brand or type of oil better than another? Im not asking about viscosity but rather more along the lines of chemical composition. I have never used additives in anything I have owned but then again I have never had a 4cycle that I was going to run at 4800 for extended periods of time. Any thoughts?

Re: What oil to use

Oil Arguements are Notoriously Heated Debates,.......

Basically, Any Good Quality Oil is Fine,........ Regular Changes are More Important than Who's oil your using......
As long as you're using an oil that Meets, or Beats the ratings that were in effect when the motor was build,.... There's Nothing to Worry about.......

Personally,.....
My boat motors All run 15W50 Mobil 1,.......
I like the Syn-oils,+ believe they Are Better..... I also run them in My drives.......
