I’m not one for mystery oils, additives, this and that, But I’ll tell you what. My 05 6.0 over the last 4-6 months has developed a horrible cold stumble at 2k-up. I didn’t know what to do. I did some research. Found this. And it completely worked. Cured everything! Just 200 miles after my oil change it was 100%. I’ll be using this every time I change my oil! Magic!
Even with storm pounding coast I got product in timely manner
I have 04 6.0 the arch oil additive helped so much on the starting seems to idle smoothies most of all it has quieted down the motor
I own a 96 F-350 7.3, 297,000 miles for 20 yrs, been havening issues with Hard starting, No power, Slow response and bad fuel mileage. I purchased Archoil, WOW!!! the 7.3 has come alive. I will use this in my other Fords (7.3). Thanks
I’ve ran this stuff through several oil changes...
Still have stiction issues...it helps but is no cure as promised... wasn’t sure how to do the refund...
