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.
Used the winter diesel treatment for the first time this year. Works great. Even during the cold spell of -10 to -15 f and winds chills of -20 to -30 and car outside, no gelling. Seems to help with gas mileage also.
Shipped fast. Use their other products also.
Order was as expected.
Ordered and shipped fast!! Very good product
Works as stated. Fuel has not gelled up.
Excellent stuff! Love Archoil.
