I was only curious what your reasoning was. I tend to go more rogue. The auto industry is moving towards thinner oils. I'm still trying to come to a decision in my mind if the thinner oils are actually "better".
Case in point, I have a 2007 Toyota Tacoma with a 4.0 1GR-FE engine. We just bought a 2018 4Runner that has a version of that same 1GR-FE. My Tacoma says 5w30 on the oil cap and the 4Runner with basically the same engine has 0w20 on the cap. So if 0w20 is "better" for the 4runner, is it also better for the Tacoma?
