Use the oil for over 1.5 years as a diesel additive for my "fat" (VW Passat 3BG 2.5 TDI, BDH motor, 4MOTION) in order to improve the lubrication of the diesel pump. Previously, I had fueled the expensive juice mobile, which also already brought tangible improvements in smoothness. The Liqui Moly in the tank (approx 300ml liters a refueling) to reach even more smoothness. The important thing here was the residue-free combustion and self mix with the fuel. Positive noticed is after the first refueling with the mixture, the extremely quiet running, excellent cold start even at below -10 degrees, no "smoke", neither in cold starts even at full throttle and I take about 7 - 7.5L / 100km. (In summer mode also 7l / 100km) even the relatively typical loud nailing the injector is greatly reduced. Say - purrs like a wildcat :-) For this purpose, by me at least a strong buy recommendation! Oh, really cheap here at Amazon and as always prompt delivery.
