Beercan, switching to 15w40 diesel engine oil isn't a bad idea in sunny FL. I like your Castrol 0w40 choice best. Using a "40" in a fuel dilution situation is smart. Those German spec oils are about as good as one can do these days.
I have complained about that to Polaris multiple times but it seems to fall on deaf ears. I like the GC a lot and will use it again, it was just that I was out and did not know it.

Except for the factory fill and the last fill it always had Edge 0w40, or more correctly 5qt 0w40 and 1 qt of 0w30. I thought I had another 5qt jug for this change but I was mistaken so I used the VPB 15w40 because it was what I had on hand.
