man this stuff really work had sticktion on my 6.0 free it up got power
Had a severe stiction problem in cold weather. Living at 8k+ ft, cold starts are the norm. I followed the instructions during an oil change with Shell Rotella T5 added 18 oz of Archoil, let the truck idle and drove the truck for about 30 minutes afterword. I expected the stiction to completely subside but it did not. The truck does seem more quiet and smooth but the stiction issue is still very much present. I'll try adding more Archoil AR9100.
Good stuff, worth the $ for a 6.0 in cold weather
I added the prescribed amount of Oil Treatment to my engine. After about 5 to 10 minutes the engine tapping noise differently decreased. The next day while driving I asked my wife "how does the car sound while idling", she said, "I didn't know the car was running". Looking forward to my next oil change to add more of the additive.
I love this stuff !!! It made my 7.3 Excursion run so much smoother. I would highly recommend this product to anyone with a Powerstroke Diesel.
