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.
Excellent service AND products from a company you can trust to get you the product you need even to Alaska! I've been using these products to decrease the usage of DEF and have found that I have cut that in half! Can only image what that's going to save me in real dollars down the road.
Got down to 7 degrees last night and didn't have any freezing issues! Everything's running good. Totally satisfied!
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.
