comparison of DEF products

[tx_maniac]

I use the 2.5 gal containers to fill my class A since the DEF pumps at truck stops are inconvenient (if not impossible) to get to.

Previously I used Blue DEF, but most recently I tried Super Tech DEF (from Walmart) which was about $4 cheaper per container.

On a recent long trip, it seemed like I used more of the Super Tech than Blue.

Anyone able to provide a better comparison?

thanks
Mike

Seems like is not a true test or comparison!

DEF is DEF no mater what name is on the container. It is required by federal law to be exactly the same. During that trip did you check your miles per gallon of fuel. If it went down then you would also use more DEF.
