Why I add 12% (one gallon) of gear lube at every oil change...

I don't even let them offer it to me at the speedco. Always walking up with their Lucas shirts and ballcaps...I tell them 'rotella oil change, fuel filters, no snake oil'

What they don't like is when I tell them to put the last bit of oil in my empty oil jug because I'm putting in my oil additive. They look at me like they don't understand though I told them I'm putting in my own additive. I told them I'm paying for a full crankcase of oil...and I expect if if it's in my oil pan or not. That's slows down your average oil tech for a couple minutes.
