Above is the newest formulation... 20w50. I suppose that .119 is not the same as .12. (insert sarcasm...)

You are fine with easy to get GT1 or VR1. Best place to get brad penn on most days is Amazon if you have prime, because with prime.. shipping is FREE.
Depending on what valve springs are in use, you may not be fine with those percentages, based on what I've seen. Those are marginal for OEM springs, however aftermarket ones are stiffer and place more demands on the oil's EP package.
