Got a '14 Rav 4 with 100k miles and been using nothing my Mobile 1 0w20. Been thinking about changing brands. Heard some good stuff by Quaker State. Can anyone concur?

I’ll give you that - but I’ve seen Subarus struggle to kick over on 0W-20 in Tahoe - these are new Outbacks and Foresters, not some beat on WRX or dirtbag Legacy wagon in the Heavenly parking lot.
Toyota backspeced to 0W-20 for the US/Canadian market because CAFE and there is a statement in the owner’s manual that “thicker oils provide better protection for high-speed driving or severe use.” It’s worded to avoid a brush with the EPA/CAFE - Toyota says indirectly thicker oil is OK. Severe use to me is towing, extended freeway runs(like a roadtrip” or gig work like Uber or Amazon/Doordash. The same engines in Southeast Asia, Australia/New Zealand and Middle Eastern/African nations allow for thicker oil.
The only cars I’ll feel comfortable running 0W-20 or even 0W-16 full time is a Honda and the new Toyota Dynamic Force engines that were designed to accommodate thinner oils. Honda was the first to introduce 0W-20 and they have a dire warning not to use anything except that.
