2014 Merc 150 Pro XS
Thought previous owner used Mercury 2-stroke DFI oil in the reservoir. However, the oil in the reservoir is more of a blue color whereas the new bottle of DFI oil that I have is blue in color. Don't want to cause any clogging in the motor by mixing 2 incompatible oils BUT my reservoir is way low (had intended on cleaning reservoir and lines and switching to premium plus soon) and I need to put some oil in it for my tourney tomorrow. All the previous owner could tell me was he used a Mercury synthetic. I know it's not premium plus because that is brown. Am I safe, you think? Can the oil change its color a bit over time sitting in the tank? I know it's been in there a while....thanks guys.
If you can't find em wind em.
