"Seeing this F-350 go from a cold-blooded, rough-running basket case to a truck that ran as smooth as it did the day it left the dealership definitely made believers out of us."
"Archoil is the Real Deal"
I just got it yesterday 7/28. I put it in my truck today, and it's helping. Thanks Jim
Saves on wear and tear!
03 6.0 with 317k miles recently developed a major stiction issue on injector 7 and other injectors are on their way out. Tried hotshots no difference at all put archoil noticed when the injector wasn't stuck it ran noticeably quieter and I did have a few times when the injector went a couple days straight without sticking but the problem still persists. Starts are noticeably smoother but after I run it a bit and let it sit for a few minutes and turn it back on 8 out of ten times the injector stays stuck closed and 3 out of 10 times I have to floor it or even smack the limiter to get it to open back up. Will be giving it another try since I did notice some difference who knows maybe after I drain this dirty oil out put some new with archoil again I'll see another difference. I only recommend it if your having hard starts but if your having injectors getting stuck closed when hot I don't recommend it if the second try does it I will change my mind.
An absolute must for any vehicles
