After the escalation in the MB thread, where it is about mixing 2 bar oil in the diesel fuel, I would like to start with a specific topic of my own. Here, it is to be against all contradictory opinions about possible harmful additives of fuels or motor oil, in the sense of fuel saving. I have carried out numerous tests and have come across a positive result, which many people here are thinking about. An ultimate additive, with which the economic sector has a positive result. My primary goal was to achieve this goal. My test engine is a 2.0 TDI BMM (140) model with pump nozzle technology, built into a Skoda Octavia Combi. The container that I collect myself consists of acetone, diesel speed of LM and 2 bar oil. It should be noted here that primary variability consists of the specially selected 2 bar oil (whether PD or CR). The combined container is fed into the diesel tank at a ratio of 1:100 with a full tank. In my case it resulted in 55 liters of tank volume 0.5 L (US additive). Here are my mixing ratios: Diesel Speed from LM: 1:1300 Acetone: 1:2500 2 cycle oil: 1:125 The 2 cycle oil in my case consists of 50% addinol and 50% monza (MITAN). Here you can distinguish between other manufacturers/ suppliers. In my engine there is currently LM Top-TEC 4200 5w30, which has been additiveed with Hydropulse and MoS2. My fuel monitor profile will be used for further discussions. updated in all aspects at regular intervals (see signature).
