I was looking at GM L87 Engine recall and part of the solution to prevent future engine failure is to change all engines to 0w40 instead of 0w20. ***....
"As for what the automaker is telling technicians to do, the first step will be to inspect 6.2-liter V8 engines for manufacturing defects. If it passes that inspection, then dealer technicians will install a new oil filter and change the engine oil to a thicker viscosity. Instead of 0W-20 that the owner’s manual originally recommended, engines fixed under this recall will get 8 quarts 0W-40 full synthetic oil instead. The underlying difference is that, at higher temperatures, the new oil will maintain a thicker consistency over the thinner 20-weight oil, hopefully providing adequate lubrication and better protection for the crankshaft and connecting rods. A new owner’s manual insert will also be included in the inspected and serviced vehicles indicating vehicles should use the thicker-weight 0W-40 oil."
