5w-30 or 10w-30?

[Infinitrium]

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.

Depending on your climate and driving habits, you would use the thinner (5W-30) oil. You said Canadian tire, so I assume you live in Canada. In areas where most driving will be done in temperatures below 40F above zero, 5W-30 is the proper oil. In warmer climates, 10W-30 is fine.

Would suggest using 5w-30.

5w30 is your best bet for these things, keeps the lifters from pumping up too much, and helps reduce the instance of burned valves.
