98901 Engine Flush and Protect Pack, (2) 15 Ounce Bottles

I had a motor fail at 235,000 miles. I purchased a junk yard motor checked it out. Compression was good etc etc. Had varnish in it, but no sludge. Installed the motor ran it with fresh oil next oil change used this. It had 81,000 on the clock and cleaned it pretty well. added the oil additive is super quiet. Time will tell so far so good.

This wasn't for me but the person who I bought it for said it was worth every penny.

Ahora el motor se siente muy sereno, menos ruidos, y tiene mejor desempeño en general muy bien. se tiene que contemplar que para traerlo a Mexico tienes que pasar un proceso de importacion de varios requisitos de hacienda

I recently used the Lubegard Bio/Tech Engine Protectant and Engine Flush, and I am very pleased with the results. This product performed exactly as advertised. It effectively cleaned the accumulated amounts of varnish and deposits from my engine. The engine flush was easy to use and made a noticeable difference in the performance of my vehicle. Additionally, the Bio/Tech Engine Protectant helped reduce friction and wear, which I believe will extend the life of my engine. I also noticed an improvement in fuel economy and a reduction in the engine's overall sludge and varnish buildup. The high-performance formula is truly impressive and delivers on its promises. I highly recommend Lubegard for anyone looking to maintain their engine's health and improve its efficiency.

Very good product... I used it on 05 GMC Denali with 240k miles. My oil pressure at idle was kinda low and had a light tick in the lifters. I didn't wanna pull the valve covers so I decided to do flush first and I'm glad I did... this stuff got a lot of built up gunk out the motor and the ticking went away and my oil pressure came back up... I was surprised at how well it work... I will be doing another flush soon to see if anymore gunk come out. Definitely Great product
