The PU is good stuff and I think it will protect your engine well even in 5W20
The car is stored for the winter now. Normally the recommended grade is 5W30 so i guess i'm getting nervous that it will be too thin and not offer as much protection when up to operating temps.
Well, as many here have said; a 5W30 turns to a 20 grade in ~ 1K miles anyway and then we 5W30 users run the OCI past 3K miles and all is well.
Then, in the spring when the car comes out of hibernation, run the car and engine mildly for a week or so(let her stretch her legs), get'er washed/waxed and looking fine then change the oil for the summer and the way you're going to be using the car.
But, the 5W20 isn't going to hurt anything for that short period of time. Now, if you hear noises right away when you start the engine after winter or while idling/cruising, change the oil soon...That's all!
Each spring when I awake my car, I allow the engine to idle for several minutes and then drive it gently for a day or two as to allow the fluids to lubricate all of the parts they're supposed to. Then I drive it normaly for a while before I jump on it. Mine is more of a cruiser anyway!
