Xtreme Green Super Duty Oil Stabilizer - Ultimate Engine Protection for Engine & Reducing Friction (32 Fl. oz. 946ml)

I have a 2005 140 HP Caterpillar Turbo Diesel in a wood chipper that would blow out black smoke on throttle up after it was warmed. I poured a bottle of this Xtreme Green SD Oil Stabilizer and the black smoke stopped on the first day. It runs clean. I'm a happy guy. I watched Briansmobile1 on You Tube and the video impressed me. I've used Lucas for years but I have seen better results imo!

The oil is really thick and it says that it stops oil leaks and oil loss but after a month still losing oil

Amazing a bit in my air compresure and he was quieter than a church mouse!

it doesn't really help me to stop burning oil in the engine that's why i rate it as a 4 star.
