Wal Mart's Super Tech DEF?

I was going to buy some but the seals were all undone under the caps so I bought some Peak DEF instead.

I have to use it the vast majority of the time because I can so seldom find it at the pumps. No difference to me.

It's all the same stuff

$7.88 for 2.5 gallons isn't bad. Not as cheap as the pump, but the cheapest I've found otherwise.

Got it, thanks.

I've used it. No problems.

I've used it or pump DEF and there's no difference. Both are API certified which is all the manual requires.
