Hey guys, not really the place to ask but I did both Google and search here... What is the “so what” of this oil? Clearly the oil doesn’t care if the motor is in a truck, but why would I use it in a car? Is it more stout than an average full syn 5w30, something like the original PU 5w30? Is it a good choice for a Subaru turbo, known to be tough on oil but spec’ing 5w30? Is the truck recommendation because it might slightly reduce fuel economy? I am thinking of it primarily for a Chevy Volt (needs 5w30 Dexos) but if has good HTHS it could probably also go in my Subaru. Thanks!
