  • Great Company and product but the cap was missing.
Size: 16 Oz
The container came without a cap. The box was sealed correctly and I checked multiple times collapsing the box flat. So glad the product didn't leak or the seal break completely.

  • Improved difference in engine performance
Size: 32 Oz
I tried this product in my car recently. Used half of it for one tank of fuel and the other when I filled up again. I believe it has made a significant difference in the performance of the engine. Hesitancy and power has increased some. I’m going to continue to use it sporadically to ensure the fuel/combustion system stays more efficient and hopefully cleaner, especially the valves. ... show more

  • It's all I use -- AND SO SHOULD YOU!
Size: 32 Oz
Modern diesel fuel is dry, make sure you add this stuff to bring back some much needed lubricity. I've been running this product for a while now and it's a nice piece of mind. A lot of people are using it, so I guess it must be better than just using straight untreated diesel.

  • Good stuff
Size: 1 Gallon
Seems to quiet the engine and hopefully I avoid a fuel pump failure with increase lubricity. Not too much difference on the mpg but I’m mainly using it as a preventative for engine damage.

  • A must have to combat today's fuel quality
Size: 16 Fl Oz, 3 Pack
2015 6.7 F250, I use this every fill up to combat poor fuel quality. Today's fuel has lots of water that will create rust , and the ethanol that is alcohol making dry fuel. Keep your system lubed up and protected with LX4. Must have product.

I researched a lot before buying this but it seems every time I add, even only half of recommended, my truck does a “DPF is full” regen. Those are NEVER convenient!
