First day on water...amazing...just a bit soaked when the sea turned a something rough, these boats are not really meant for it, I know...but this is like a fiord and normally calm in the summer.
Well, I checked the boat fluids levels like the owners manual says.Closed cooling system expansion tank was dry,not the exchanger luckily...Manual says about some Sierra brand propylene glycol antifreezer, I just added destilled water cause weather here is warm, but could i use any other propylene glycol coolant?.
Engine oil level was right after 5 hors running, but could i MIX the original Pennzoil oil adding another approved by owners manual oil type?.
Transmission and V-Drive oil both were low so, I have the same question about MIXING oil types cause I canīt find Pennzoil products here.So can I refill both systems with another approved oil brands I know I can use other oil brands, just not sure about mixing them when refilling the level.

Thanks in advance

Yes you can mix brands. Try to go with ones that have the same properties and ratings.

Hope this helps
