Hot Shot’s Secret LX4 Lubricity Extreme 16 oz Squeeze – Treats 160 Gallons – Fuel Additive for Gasoline and Diesel Engines, Lubricates and Protects Fuel Pump and Injectors, Prevents Wear and Damage

I must say that I up keep my Explorer in everyway, oils changes on time religiously, coolant flush on time, all scheduled maintenance done on time, but I drive a lot of miles, 124 miles Monday through Friday, more when I have to pick up my daughter. So the wear and tear happens no matter the upkeep. Lately I've felt the car somewhat sluggish and I happen to fall upon this and read what it offers and decided to give it a shot based on the reviews. I must say that the difference was night and day, the car became more quiet, drove smoother, enhanced performance on the highway, it was a real noticeable difference. It just felt so much better when I put my foot on the pedal. Now with that said, I really didn't noticed better MPG, and maybe that was because I upkeep and baby this car. This was very simple to use, simply use 2 oz per fill up, you squeeze the bottle and it has a 1 ounce fill cup on the top of the bottle which is beyond helpful to make sure that you do not over use. I've driven over 2k miles since using this and I can assure you that it will not be a major part of my upkeep.

been using in my 2003 7.3L we got in 2015 and now in 2017 ram 6.7l cummins we got in 2024.. keeps thing clean adn running smooth.. does it help with MPG,, not sure as I have either used HotShots or Archoil for 2 bottles then back to HS. Recently got a bottle of Power Service Diesel injector and DPF flush to help as well.. check it out..

Seems to last a while and is not too thick like some other products I’ve tried, which makes fill ups faster. I would recommend getting a small bottle with a nozzle to pour it in the take with but the product works just fine.

Really helps improve MPG, improved performance and efficiency for diesel engines, upgraded American diesel fuel to European standards

Great product

I use this to (hopefully) prolong the life of my Bosch CP4 high pressure fuel pump in my Superduty. Only have 28k so far but zero issues. 4 oz per tankful is what I use.

All I use in my 6.7 power stroke with CP4 pump.

I've been using Hot Shot's Secret LX4 Lubricity Extreme for a few tanks now, and I can really feel the difference. My diesel engine runs smoother and quieter, and I like knowing that the fuel pump and injectors are getting extra lubrication. It's easy to pour and mixes well with either diesel or gasoline, and I appreciate that a little goes a long way. The protection it offers to prevent wear and damage gives me peace of mind, especially for long trips. Highly recommend this product for anyone wanting to prolong the life of their engine.

Arrived quickly thanks.

Good

Smooth! Please monitor your motor oil level closely the first few fill-ups. If it increases above the max dot, lower the treat rate.

Great product, noticeable increase in fuel economy!
