Have you documented any changes in your truck since using your product? DEF/Fuel consumption, drivability etc. I have read about other people having problems at dealerships (Jeep) refusing to honor warranties when they use non OEM supplied DEF. Have you had any such problems?

Thanks to both of you for working towards solving this problem.

D. Greenman asks an excellent question.

Our F350 works perfectly with over 15,000 miles using over 17 gallons of our own DEF. Our truck runs perfectly. We were recently at the Ford dealership for a problem related to the Navigation System. During diagnosis, the dealer scanned for any issues, and found none. This indicates the SCR system is working perfectly. Our truck carries signage for Five Star DEF, and they were asked about it. They have no issues with us using our own DEF as long as it meets the specification.

Here is a direct quote from the 2014 Jeep Diesel Owners Manual under Maintenance:

"MOPAR® Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that has been
API Certified to the ISO 22241 standard. Use of fluids not API Certified to ISO
22241 may result in system damage"

Five Star DEF has been tested and meets ISO22241 specification requirements. Five Star DEF exceeds API certification requirements since each lot of automotive grade urea we use is testing by making DEF and having it tested per the ISO22241 specification. We do not have the API certified mark on our product because the API does not offer certification for DEF unless it is liquid. The API web site regarding DEF is very clear: The API certification program is optional.

Five Star DEF guarantees that DEF made with our product per our instructions meets ISO22241 Specification requirements.

Requiring OEM DEF is like requiring OEM oil at an oil change...

What it essentially comes down to is individual dealership response to non OEM supplied DEF and any warranty claims on that system.

Having a hard copy of the above noted information (along with web links) that is carried in the vehicle may help to alleviate any prolonged discussions at the dealership should the need arise.

Hi there! I know this is kind of off topic but I was wondering which
blog platform are you using for this website?
I'm getting tired of Wordpress because I've had issues
with hackers and I'm looking at options for another platform.
I would be fantastic if you could point me in the direction of a good platform.
