I use AVblend in all of my engines and transmissions. I have noticed over the years that it helps with the lack of tarnish build up in the engine.
ProsThe way it protects the engine parts from metal fatigue.
its ability to bring back older engines at a slow and steady rate.
The way it keeps the engine clean and reduces friction on the moving parts, in turn reducing the heat produced.
ConsThat it no longer comes in the 32oz bottle.
