Protect High Pressure Diesel Fuel Systems
The ASTM D-975 Diesel fuel specification requires diesel fuel sold in the USA to produce a wear scar diameter no larger than 520 microns, while the Engine Manufacturers Association recommends diesel fuel to produce a wear scar diameter of no larger than 460 microns.
This means fuel that meets ASTM D-975 may not be lubricious enough to meet the Engine Manufacturers Association's recommendation, and therefore may not provide adequate protection to modern high pressure diesel fuel systems.
AR6300 will help protect high pressure diesel fuel systems from failure due to inadequate lubricity.
so far its working it is -3 here now, we will see
My 20 year old truck had been a little cranky as of recent starting below the freezing mark. The smaller the number outside the more cranking has been needed. On my second tank of the Archoil winter additive and at 18 degrees she fired up in moments! Y'all's stuff rocks!
Works just like AR6200 with additional protection for cold operation. It's amazing how quiet my injectors are when using this product.
It would be awesome if you guys would send a smaller additive bottle to use when you buy the gallon jug.
I hope this works much better than Power Service because that stuff is garbage. I had a lot of problems this past winter when it was -25 degrees. My truck never runs good in cold temps so i hope this helps.
