BTW, I can buy Mobil 1 for about $3.25/qt. Assuming that I get 2% better gas mileage with it, my ~20 mpg van saves about $3 of gas during the 3000 mile change interval. In other words, the cost differential between dino juice and Mobil1 is .... $16.25 (Mobil 1) - $5 (dino juice) - $3 (fuel savings) = $8. Maybe it's not so expensive after all.
