Lucas Oil 10873 Diesel Deep Clean, 64 oz.

In have a 2016 Nissan XD with the 5.0 diesel with a 27-gallon fuel tank. One Sunday about a year ago I went to my local Pilot station and filled up with diesel, on my way home my truck went into limp mode and shortly after showed a "DPF Filter Full" fault. I was able to limp it home and got on the internet to search for a fix and several people said to use this product. I needed the truck for work Monday, so I got a 16 oz bottle (treats 30 gallons) from my local auto parts store. I poured it in the fuel tank and went for a drive within 10 minutes the limp mode disengaged and within 30 minutes the "DPF Filter Full" went out and the truck has run great ever since! When I bought the truck in 2019 it had 28,000 miles on it and I could get 19.5 MPG on a trip to visit my dad since then the MPG for the same trip had gotten down to 17.8 MPG (the month the incident). I have been told by several diesel mechanics that this is normal with the DPF filter exhaust system that they start clogging up and the MPG starts going down and the only way to fix it is to replace the filter ($$$) or take it off the truck and clean it ($$). I am now buying this in the 64oz size since it is now over $20 for the 16oz and I am putting16oz in at every 4th fill up. Since I have been using this my MPG for that same trip is now 20.2MPG and the only thing I have done differently is added the LUCAS Deep Clean Diesel! Not only that but the truck feels more powerful and runs smoother.

It says 6x1 so I was expecting 6 bottles for that price and I got 1 so not to happy .

This is the absolute best stuff to clean out the DPF system. I go from about 250miles between regens to about 400ish miles which is about what I got when my 2022 Silverado 3.0L Duramax got when brand new. I HIGHLY RECOMMEND THIS PRODUCT!!!!

Works great although pricey

Didn't notice any improvement
