About Hot Shots Secret LX4 Lubricity Extreme 1 Gallon Bottle
Overall Feedback:
83% positive
76% praised the compatibility
I have been using the product for over 10,000 miles and want to provide added protection for the fuel system and injectors.
My 26 year old truck's mileage increased by just over 2 MPG in 70 miles after using the product.
After running the diesel-additive through the fuel system for a few hours, my engine runs a bit smoother at a slightly higher rpm at idle.
75% were impressed with the easy-to-use formula
The product has significantly improved the engine's performance.
After using the product, I noticed a slight improvement in fuel economy and throttle response.
80% found it fuel efficiency
This diesel-additive is a huge blessing for me as I believe pre-2007 Duramax engines were not engineered for the lower lubricity of modern diesel fuel.
88% praised the fuel system cleaning ability
I suggest adding the product to modern diesel fuel to restore lubricity.
I will continue to use this product in my Silverado, as it has effectively cleaned the fuel system of my diesel engine.
