Review on Restore Your Diesel Engine Performance With Archoil AR6400-D Fuel System Cleaner by Angel Serafini

I used this product in December of 2020, about 5 thousand miles ago. I regularly use the Archoil oil additive and try to use the diesel fuel treatment too. As I was getting my emissions done today I found my inspection sheet from just before I used the Archoil Fuel System Cleaner. As you can see, this product alone lowered my Opacity reading by 2.4 points! Great product, works better than expected.
