Dramatic change in DPF regeneration

I have run arch oil AR6300 in three tanks of fuel so far and have noticed a dramatic reduction in DPF regeneration. I can’t speak on fuel mileage as it has been super cold here in Michigan, but, I’m hoping for better results in the summer.

I am a big fan!

I use this in all my Diesel engines due to leaving what happens when I don't. When your Diesel gels up and does not work when needed is a bad day. I plan to not let that happen again. With Archoil and powerstroke help. Thank you so much!

Will not go with out it!!!

I have been using Archoil for almost 7 years now and I truly believe in it!!! Before I started using it I had some very rough start ups but no more now it cranks with no issues whatsoever!!! In my opinion it’s a must have!!!

Review of AR6300 Winter Diesel Treatment

Great product used at every fill-up im from central Iowa and the temps this winter have not reached negative temperatures yet this year. The real test will be when temps dip below 0°F Archoil makes handsdown the best diesel fuel additives on the market I encourage all Diesel truck owners to use Archoil in their trucks!
