DEF = poor quality DEF left me stranded

You can buy a tester for less than $20. on line, looks like an antifreeze tester.

Can u suggest one and any site and how to test before u fill up Plz
As I think it would b great help and will save $$ and downtime ,

 

Here is what a quick search on Amazon brought up.

I have used two different styles of DEF testers. The one that you put DEF on the lens and look through it at light (refractometer) and the digital kind. The one that you look through is very finiky. The digital one is very accurate and easy to use. The bad part is that the digital one is expensive.

What you can do is test some once you get it out of the nozzle to see if it meets specs. The main thing is to test what you have in the tank. I have seen it vary up to 5% of what it should have been after a day of running. The heat does change the percentage of DEF in the tank because it will help the water evaporate out of the tank when things are hot. I hope this helps.

 

Interesting on the tester I didn't know that.

Seems like a fella should pump into a pail first to test it. Then if it passes, fill up. I don't have any DEF trucks but that seems like a prudent course of action.

 

That's why I should stay out of cali and buy glider.

 

Were you the fella that had so much trouble with a DPF engine and auto trans a while back that you traded it in?

 

I read a PDF on SCR and DEF quite a while ago, and the concentration is such that it stays mixed when it freezes, (doesn't salt out). The lines on the truck need to purge after shutting down, and there is never any water in the air tanks on this truck, so maybe that is why it works as reliably as it does.

Thank you, saved me a lot of reading.

 

Maybe not....... much will depend on just a couple of factors like how many complaints , your proof of purchase and their ability to verify and match.

Gonna take a little while tho......good thing about majors like Pilot is corporate customers and their hate for bad publicity........

So...if he bought a load of DEF on this date.....and along comes Lucar and JB's, Swift, Schneider etc and they all have complaints.......but again, that will take a little while to compile the data.
