My chassis is at 162k, I have my doubts about the age of the engine, it's very easy to remove any of the bolts on it. For example the P-side exhaust mani bolts came loose with nowhere near the effort I've seen on other high mileage cars. Compression was 130 across the board, at 5500 feet of altitude.
I just have my doubts about the effectiveness and useflulness of thicker oil like that in a car that probably won't see much high performance use. Simply to prop up a lifter tick problem, I don't think it's a good idea. Best to fix whatever causes that in the first place, IMO.
