The best for keeping ULSD fuel clean & it lubricates everything
400k miles on a 2019 Powerstroke. I add a bottle with every fill up which might be overkill but the CP4 and injectors must be good bc it crancks right up daily. Be ready to change the lower fuel filter more often bc the OptiLube gets way more gunk out of your fuel making the filter more effective. I use it in my diesel SxS, John Deere tractor and Ford trucks. I’ve never had a problem with the engine on any of them after 7-8 years regardless of the temperature.

Best customer service
I’ve heard great things about this product so I wanted to give it a try. I purchased the kit that comes with the Opti-Box and 8 4oz bottles of XDP. I received my package today it was missing the Opti-Box so I reached out Saturday and they emailed me Monday morning. I’m really looking forward to using this product best it’s great to know they have awesome customer service as well.

Paid extra for optibox. Did not come with it.
Didn’t come with the optibox, no reason to pay $12 extra for a case of 8 with box vs jsut case of 8, if not coming with the $15 optibox… Edit, they did reach out and make it right after the review was posted.
