"In the manual, it says that QuickSilver is recommended and the manufacture DISCOURAGES the use of multi-viscosity oils, such as 20W-40 or 20W-50.
However, in trying to avoid buying my oil at the Marine shop because of extremely high prices, I found QuickSilver 4 Cycle Marine Engine Oil at my local Canadian Tire Store, but it is 25W-40 and that's all they have. Does this force me to go buy it at the Marine Shop or is this 25W-40 actually okay to use? This will be during the winterizing of the boat by the way. 120HP Mercruiser is what I'm working on.
Also, would a 350g can of Engine Fogger be enough for a motor this size?
Thanks guys!!"
