I've had excellent results using Auto-RX. That and Techron are the only additives to do exactly what they claim to do in my experience.

Auto-RX is a lot of esters that very slowly dissolve gunk and varnish without harming your seals. I can vouch for it, having used it in the past on my Buick, where it stoppered up a seeping valve cover gasket nicely.

After doing the math with a 0.05 gph drop, I figured out that it's saving me about $30 in gas (assuming 0.05 gph less gas used, 15 hours/tank, 20 tanks in 7k miles, and gas at $2.50 a gallon) at every 7k mile oil change. With a dose running about $4, that's still money in my pocket.
