AdBlue for 2015 ML250D

Hi, is there any reason not to buy the Ad Blue equivalents that I see online and at the auto parts stores? Is there a specific product that you would/would not recommend?

Thank you, Ed

Even available at Walmart. Just check the dates to be sure the product is fresh.

I get it from VW dealers, its the same ISO as MB uses. 2.5 Gl for $18. Not too bad.

A gaggle of MB's
Frabkly - best refill is using PUMP DEF at a auto truck stop.

ON DIY Def - use ONLY the plastic filler tube built into the package - and NEVER use any metal funnel/pipe - and frankly I am NOT a fan of keeping partial container of "old" DEF around - subject to age and temp degradation - I throw partially used cartons away..

I'm curious; Does old DEF throw a code, or is it simply ineffective?
