the walmart labelling is wrong or old stock.http://www.techronclean.com/en_us/products/techron-complete-fuel-system.html
The current product page says the marketting should mstch 1oz treats 1gallon of fuel. i.e. 10oz for 10gallons.
Of course treatment strength is completely arbitrary, if 10oz of product is run through whether its diluted with 10gal or 15gal, does it make a difference in result.
Plus if you are the person that buys techron likely you already use toptier fuel, so theres nothing to cleanup, so who will complain.
