Thank god for Benzmac!!
My car is nailing a little bit, so I changed the filters and then filled them up with Red-line diesel system cleaner. I then changed my oil and added Lubro-Moly Hi-test to the tank, but it still knocks. I was going to run the Lubro-Moly Diesel Purge, but I thought the injectors may be leaking. What are your thoughts on this, I know obviously the Diesel Purge is less expensive, but will it actually quiet the nailing? Other than that the car runs fantastic. It has 165K on it and I have every single record for the car.
