Lucas OilLucas Oil 10872 Oil Diesel Deep Clean, 16 Ounce

Used this when my truck was giving me issue. Great price, in the QT truck stops they are selling this for 75$ per bottle. Purchased some extras to keep on my truck.

Great diesel additive

I run this stuff through my Titan diesel every two or three months, and I'm very happy with the results. I'm typically not a fuel and oil additive type guy, but I will keep using this product as long as I own a diesel truck.

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.

👍👍

If you have an engine light from a diesel particulate filter clog, this treatment may work after a couple of tanks. However, I needed a new sensor and this treatment won't fix that. Do yourself a favor, get the sensor fixed soon or you may find the truck won't go above 50 MPH, which is the EPA's way of forcing manufacturers to keep the emissions working properly. I was stuck in Pigeon Forge, TN with a reduced speed and spent over $1K to get the sensor replaced. To say the least, the Ford dealer in Sevierville took me for a ride on the labor charges.

Excellent product

My check engine light came on in my 2011 Golf TDI and the diagnostic code said p2002 (if I am remembering correctly). I looked it up and it said there was an issue with the diesel particulate filter (DPF). Apparently diesel cars have to be driven long distances relatively frequently to burn off the soot from the fuel combusting. And this little device they started adding to diesel engines in 2007 (I think) catches all of the soot if it's not burned properly so it doesn't go into the air. If the DPF gets clogged and doesn't regenerate and burn off the soot by itself (it usually regenerates when you have driven over 40-ish mph for at least 20 min) replacing the DPF will run you around $3500 on a car like mine. So after some research, I looked up products that can help. Boy am I glad I did. It took a 45 minute interstate drive and a couple of days of short errand drives for the light to go off. I had recently filled my tank, so I added this bottle directly to the fuel tank at about 3/4 full and then filled up the rest of the tank with diesel fuel. And then I prayed. This was easily the best $20 I've spent in 10 years.
