DEF Concern/ Question???
Does anyone know about DEF, Walmart sells Peak brand in 2 1/2 gal box for $12.88 but has there off brand at $7.88....Is there a good reason to pay the higher price for Peak brand. Thanks for any response, It's not convienant for me to get at the Truckstop fuel island because my 2015 Aspire has the tank at passenger side rear and the DEF hoses won't typically reach.
