Hey Man, Stick with the BRP oil, I'm running the blend in both 09 and my e-tec, I wouldn't want to risk my warrenty using another brand oil if I had a failure. Engine is too new and has alot of expensive technology in it. Just my 2cents.Anyone know if using Amsoil on a new unit voids warranty? Namely a new Summit 800 etek. Don't know much about BRP machines.
i agree with caper11 stay with brp untill warrenty expires then you can switch to a cheaper priced oil
I'd put money down that AmsOil is a better oil than the BRP stuff any day --(unless the BRP stuff is made by AmsOil!) BRP does not make it's own oil anyway, they just put their name on it, put it in the fine print of their warrantee and charge the guts out of you for it. It's probably Mobil 1 oil.
What do you base your opinion on. BRP oil has done me no wrong in the last 15 years. Does Amsoil operate an oil refinery???????
What he said
I rebuilt my 2002 mountain ct triple at 1700 miles. used exclusively AmsOil Dominator oil for 2 stroke. At 3500 miles my balance shaft went and required another teardown. After 1800 hard miles you can still see the crosshatching in the cylinder walls! I use only AmsOil 0w40 4 stroke synthetic in my new Z1 Turbo. In my humble opinion there is no better oil.
It sounds like that oil works really good!!:d Good oil and rebuilt engines should not be used in the same post.
I replaced a cracked piston in my 583 at 12,000km and the cross hatch was still there, using BRP mineral oil.
