Mercury oil

[TightlineT]

I have a '03 225 hp Mercury EFI. I have always used Quicksilver in my old Mercury and plan on doing the same with the new one. Question is, there is red label Premium oil and Black label Premium Plus... I've read the labels with little difference, but I was wondering if there is one or the other that I SHOULD be using. Thanks for the help....Jim

Thanks for the response. I think both have the specs you describe, so it probably doesn't matter.....Thanks, Jim

I believe the Premium Plus is a synthetic/dino blend where the Premium is pure dino. The Merc DFI oil, recommended for most Optimax engines, is a 100% synthetic product. You could probably look on the Merc site and find out for sure.

yea that could be,i know the opti's are picky,that 225 efi is one of mercury's best engines,,,iv'e been told by the boys at the merc factory in wisconsin,they said it is the most cost effective as warrenty repairs go on any hp motor they make,,

I run the quick silver premium plus in my 300report stroker and have had zero problems

If you idle around a lot 100% SYN will not cause as much carbon build up.
