Great product my trucks run much better!
I’m very pleased with the results of both my first oil change, and the first three tanks of fuel using the combined products.
My vehicle: 2005 Excursion 6.0
I only did the first step with the AR6400 Fuel System Cleaner, and I can notice a difference already... my cars has a little more pep to it. when that runs through I will add the AR6200 cant wait to see more good Iresults.....
Your products are amazing, 2nd time I purchased it, and my powerstroke runs completely different. Plus got it on sale 👍
I’m sold on it for sure,
Shortly after purchasing my Duramax my son (who owns a rattling smoke belching diesel Australian Troopy) put me onto your product. I have been using it since and am pleased. Last year I purchased a 42' coach with a Cat C-13 engine and have been using it there also. So far so good.......'keep up the good work.'
