Ok to use Shell Rotella Synthetic Oil?

[cts0037]

I am about to change the oil on my two SeaDoos. I have a 2013 GTX 155 and a GTI 130.
I would like to ask if the Shell Rotella Synthetic Oil works well. If so, is 5w40 good?

I am going to tune them up also. Does anyone have suggestions for buying plugs, oil filters and oil?

Thanks in advance.

Both your skis are non supercharged so any good quality oil will work check the owners manual to see if 5W 40 is an acceptable viscosity. Spark plugs I get by the box at an auto parts store and oem filters from the dealer.
