Shell Canada has rebate's on Rotella oil , 7.00 $ on 5 litre T-6, 5.00 $ on 5 litre T-5.
This rebate is good till 2020.
Online or mail in rebate.
I picked up five jugs @ Peavey Mart, they had it on sale for 15.00 $ off per 5 litre at Christmas , with the rebate its 22.00 $ off per 5 litre.
Works great in the Duramax and the quads.
