    Ultra 250 oil

    I am going to be changing the oil in the Ultra and I was wondering if anyone could share what kind of oil they are using. I was thinking about 10-40 amsoil synthetic but I only have 16 hrs on the ski so i was going to wait until about 25 hrs to go synthetic. Also any other ideas on this subject would help. I have also noticed a little oil around the tube entering the air box, and I plan on cleaning that up. The ski still has the break in oil in it. I appreciate any help.

    For grins, i will reply to this well covered topic simply to post what oil i currently use and why only.

    I currently use 10w-40 Castrol 4T, petroleum based. It meets the specs to the tee. It's also $3 -$4 per qt, which really means to me that i can change my oil more often.

    If i ever switch to synthetic, Mobil 1 will be my choice unless amsoil rep can send me wholesale pricing info without making me hunt for it.

    I did not know the 4T was available here in the US. See I learn something new every day

    Have you done a leakdown test on the ski yet? That will tell you when your rings are seated and when you can switch. This is the AMSOIL I would recommend. 10W-40 AMSOIL Synthetic Marine Oil http://www.amsoil.com/redirect.cgi?zo=367509&page=storefront/wcf
