Sorry for being slow, but can someone discuss the items on these two charts in a bit of detail?
I'm trying to decide between 3 dino oils and I'm tired of being obsessed by this.
I use Castrol, but don't mind switching.
I can't find a chart with Havoline's specs, but that's the third choice(and the most convenient).
Thanks for my pending education.
