I think they should use my friend as a poster boy for sludge protection. Let him use the oil ( actually you would have to change it for him since he doesn't actually ever CHANGE the oil) and then follow the results.
Trust me, if the engine stays alive, its great oil!
maybe then they could name the test after him.
It is so flippin lame that I can't even take their product seriously. Engines are expensive, and though the oil may be alright, I feel like I'm putting in some cartoon-disney-oil for children.
Might as well say Fischer Price on the bottle.
I switched to Valvoline when I saw ads (and actual useful product data) aimed at serious minded car owners.
