LX4 Lubricity Extreme– 16oz - Fuel System Protection– Lubricates and Protects Fuel Pump and Injectors– Prevents Wear and Damage – For Gasoline or Diesel Engines, Packaging May Vary

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.

AWSOME PRODUCT, CANT GO WRONG WITH HOTSHOTS

My fuel injectors are 22 years old, and have received a lot of tlc to keep them going strong over the years. The fuel pump is not quite as old but could definitely benefit from this. I had it go bad once and it was a nightmare pump to replace, and pricey. I’m hoping this stuff will provide some cheap insurance. I love the company, they make some great products. This is simply a solvent free high quality oil. Ethanol removes lubricity from your fuel so this is a great way to replace it. After running it through the fuel system for a few hours, I’m noticing the engine runs a bit smoother at a slightly higher rpm at idle. I was also getting a recurring lean engine code intermittently that hasn’t come back since I started using this stuff, fingers crossed.Update: definite improvement in gas mileage! Went from 17mpg to over 20

Hotshot secrets puts out great products and I have used just about every one so far. I use the LX4 product mostly in my VW jetta TDA as it has a CP4 high pressure pump that is known to go bad without proper lubrication in US diesel! Works great and havnt had any issues so far. Lasts a while when treated at recommended treatment levels!

I use this in a 1997 Ford F150, a 2022 F250, 2016 Ford Explorer and a 2019 Ford Edge. Purchase this by the gallon jug. Will not be without it. Vehicles run so much smoother. From start up on -15 below mornings (all but three vehicles sit outside) to running down the Interstate at 80 mph. You notice the difference. A lot of gas stations have alcohol in their gas up to 20% (pump says 10% but law allows more and sometimes that alcohol separates out in the in ground tanks). That alcohol burns just fine, but today's engines need a little protection from what is being delivered at the pump.

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.

If you’ve got a 10-16 D-MAX, you should already know the situation with the CP4 fuel pump. The diesel in the U.S. doesn’t have the lube in it like the old days due to emissions. The fuel is too dry and the pumps are “Grenading” on people. I use a lot of Hot Shot’s Secret products on my truck without any issues. I mix this with the HSS Everyday Diesel additive at every fill up. It’s a phenomenal product and well worth every penny you spend on it. If you have any questions, contact HSS website and it will get you where you need to be for an answer. I’ll keep using this until something better comes along. Until then, best of luck.T.H.

Great
