525 EFI Oil
A Merc guy at Miami STRESSED that I only use the Merc 25/40 oil in this motor. Local shop was selling it for 5 bucks a quart!!! :eek: Since this is a common engine, what does everyone else use? And if I have to use the Merc oil, is there an online retailer that has it cheaper?

Once they are broken in I'd go to Mobile one 15/50 synthetic.

I agree with Marginmn, the pressure won't drop as much when the temp goes up (extended wot).

Thanks, going to do a change soon. Rackster, did you get my email with my info for the warranties?

Re: 525 EFI Oil
We've been using Merc. oil 25/40 non-synthetic becuase they are under warranty and that is what Merc. says to use. We buy it from West Marine it's like $2.
Some people say the Mobil 1 synthetic is too slippery for the cam. We have also been using Merc. oil filters and they have having problems with them collapsing so be careful with them if you use the Merc. Oil Filter. |

I just picked up my boat from my servicing marina after they re-commissioned it and they used Kendall straight 40 weight oil in my HP525 :eek:
