I've read recently about MMO, and i heard good things about it. I got some and added it in the Tahoe, but its the first tank, and i havent driven it enough to formulate an opinion on how well it works. i have also heard you can sub 1 quart of oil for 1 quart of MMO in the next oil change. has anyone done this?

I have not added it to my current truck, but I have used it in my oil in the past. It works wonders for ticking lifters. Have you noticed any improvements on your truck by adding it to the gas yet?
