Four Stroke Engine Oil?

[frictionhead18]

Can someone recommend an oil for four stroke ATV/Motorcycles, used in farm work applications?

Castrol 20w-50 4-stroke motorcycle oil is one choice.

The dealer told me to use ONLY Bombardier oil.
The service tech said that he has never had engine damage when the Bombarier is used. The oil is $9.00/quart.
Does anyone know who makes Bombardier oil.

I also had a Can-Am dirt bike in which I used the Castrol. I never have had a problem.

You will not void your warrenty by using oils other than bombardier.

I would recommend Amsoil's 0w40:
