40:1 or 50:1 premix?
So i changed over to amsoil HPI this weekend from the standard XPS seadoo oil. I had been mixing 40:1 with the XPS oil but the Amsoil says 50:1. Since i realize the Amsoil is made for a variety of devices, other then just sea doo. Should i use their recomendation? Or stay with 40:1?? Thanks!!
Also, if anyone is curious. HPI is great!! Near zero smoke. And you don't get the two stroke gag you smell as with others!! And it's a few bucks cheaper per gallon.

I have been running at 40:1, even though 50:1 is what is recommended not only on the bottle, but by the experts here.

Ok cool, thanks guys!! I figure the extra oil may be a lil added protection. Just making sure it wouldn't gunk up anything.

I'm not saying I am right, just what I am doing. I know when I go to Norris and have to use the gas stations, I end up being anywhere in between 40:1 and 50:1 since there is a bit of guess work involved when filling it up. I have to find time to pull my head one of these days so I can post some pictures.

I called Amsoil and asked their oil tech, as a couple of my skis are highly modded. He assured me that their oil would provide superior protection at 50:1. So far...he is absolutely right. It barely smokes, and seems to have better performance too. One ski turns 7760 regular with a lightened Rotax crank.
So after talking to him, I would go with what each oil company recommends. BRP recommends 40:1 for XPS, or Castrol does, but if an oil does a better job and only requires 50:1, there is no need to waste your money mixing richer.
Just another opinion for the mass of oil oil opinions...
