Bombardier oil has just went up in price in my area. It goes for around $28.00 for a 4 litre jug (1.06 Gal). I can buy Castrol Super Snowmobile Oil at the local Wal-Mart for $13.97 for a 4 litre jug. We all know that Castrol makes Doo oil. My question is what do they put in the Doo stuff to make it double the price of the Castrol. They both meet all the same requirements, what do you guys think?
