I'm not sure that every 0w20 oil is subject to consumption. Dexos it goes to GM cars, and many brands of cars already drive 0w20 oil. The new Toyota Land Cruiser 300 generally recommends 0W16. But here everyone decides for himself what to risk. Servicemen claim that Xw30 or higher oil does not lubricate the engine well. Personally, I think that their words are not without meaning. Therefore, on my last Tahoe K2XX with a 6.2 engine, I drove all the time (160,000 km) in 0w20 oil, topping up 1 liter for about 10,000 km. Just tried 5w30 onceAlthough I'm sure I'm not smart enough to figure out why, what if 'DEXOS' is part of the problem?
Put another way:
Is EVERY xW20 more susceptible to oil consumption, or is it just DEXOS xW20 motor oils?
For whatever it's worth, I think y'all may need to consider getting tuned to lower your pcm's fan-on thresholds, or a slightly cooler thermostat, or invest in some other form of motor oil cooling, or maybe just use 0W30 ... I dunno.
In related news, I'm about to go on a VERY long trip, for which I'll be using Valvoline Modern Engine Oil 5W20 in an attempt to improve my fuel economy.
Now I'm gonna buy some Valvoline Full Synthetic High Mileage with MaxLife Technology 5W30, just in case oil offgassing / consumption turns out to be an issue.
