Walmart has a sale on their Tech 2000 brand of oil, $3.92 for a 4 liter jug of 10w-30. This particular Walmart stocks 4 different types of oil filters for the 1 liter engine, Honeywell Defense at 3.74, Fram regular at 4.48, Fram Doublegard at 7.47, and Fram Extragard at 9.97. I don't like Fram at all, but I've never heard of the Honeywell Defense filter. Anyone use it before? I'll get my oil at Walmart, then go to Canadian Tire and get my oil filter and 2 packages of the Motomaster V-groove plugs. They're on sale, 2.25 per package of 2 plugs. IS 10w-30 the proper grade of oil I should be using? I know the manual says 5w-30, but I see people recommend different grades of oil.
