Oil requirements for 2007 Verado 250

[Gettin Busy]

I am in Grand Bahama and have no dealer available to me at this time.  This makes it tough to get such items as QuickSilver oil for an oil change as it is a hazardous material and costs extra bucks to ship over.  I was told that I could use other oils if they met certain standards.  Cash Marine in Freeport sells Starbrite Synthetic Blend 10-30W and it exceeds CF-4 and CH-4.  I have no idea what that means and I am seeking some expert advise.

Thanks,

Match 20w-50

or 10w-40

Thanks Glen.  I am assuming the Starbrite brand is ok, just make sure it's 20-50W or 10-40W.

oil is oil - no motor manufacturer owns a refinery - it all comes from the same place if it has a good name.

Glen,

I'm in a similar situation--In HI the Verado Oil goes for $38/gal (when available)and since I run the boat every or every other weekend I'm changing oil every few months on a pair of 175's.  What do you run in your Verado's?

Thanks

i have run everything from 10w30 to 10w 40 to 20w50

lotsa controversy here but IMO if unless you are in the sahara and running always above 5000 rpm,  I think the key  is not what viscosity you run but how often you change it....

This is just my opin and worth nothing - you have to make your own decisions...the only thing I have heard recently was the new yellow bottle 25w-50 from merc had additives to fight off "fuel in oil" dilution that all 4 strokes can create.
