Just bought a Nitro Z-7 with a Mercury 150 Optimax. The person I bought from gave me a gallon jug of Mercury direct injection oil. (Didn't know it even existed). My question is I've always used Mercury Quick silver oil. What if any difference is there, and should I be using the direct injection oil?? Thanks!
My 2014 Mercury 250 Pro XS is recommended to use the DFI oil. I know folks will say you can get away with using premium plus or a myriad of other oils, but that is what Mercury says to run in it. Considering what it costs to rebuild one, the little extra I spend on oil is worth it to me. I do a lot of idling using my graph and have never had an issue with fouling plugs or any other issue with DFI oil so I'm gonna keep using it. It is a pure synthetic so it is going to be higher than blended or pure fossil oil. I do run Quickleen and Quickare in every tank also. Do your due diligence and use what you think will give you the best results for your money.
