[QUOTE="wiltshp, post: 4980163, member: 49822"] buddy, I think you are fine with 5w 20. The two numbers stand for the viscosity when the oil is cold and when the oil is at operating temperature. Too get an oil to have more than one viscosity (straight weight oils only have one weight I.E. SAE 30) they have to add polymers to the oil that straighten out when the oil gets warm to give it a thicker property. The further the two numbers are apart 5w20 vs. 5w 30, the more polymers they have to add. This takes away from the oil's abilty to lubricate, which is it's primary purpose. [/QUOTE]
