I have two Toyota V8s (2014 Tundra 5.7L & 2012 Lexus 4.6L) and am wondering if there are any high-quality 0W20s that might offer some advantages to the factory-fill TGMO 0W20 synthetic. Being an old school car guy with a thick head I still run 6k OCIs for these engines which usually equates to approx six months of driving.
It would be nice to find an oil that could match the TGMO's cold start performance at -10F but offer improved (at least on paper) protection for hard use while towing or mountain driving. Both of these trucks regularly tow ~2500lb trailers and travel over mountain passes where the engines are often run @ WOT and high RPM for long periods while climbing and passing slower traffic. Most commuter cars would never subject TGMO 0W20 to this kind of abuse which got me thinking that a light 0W30 like M1 AFE could be a good match for the engines, especially since I am not worries about warranty implications or possible impact on fuel economy.
TGMO gets a lot of love on this forum and I have no reason to believe it isn't an excellent oil but for my usage and without worrying about cost or extended OCIs is there something better?
