First of all what do you have for a powerplant in the mercedes?Okay, I ran out of fuel today on the way to work but luckily, I keep a small auto parts store in the trunk of my car. Soooooo, I tossed in about a gallon and a half of new 10w 30 oil and finished the drive. The fuel filter was a nice golden color, showing that I had pure oil in the lines but I had absolutely NO smoke. None. None at idle, none while driving, and none when I floored it.
Now, my car smokes on anything, especially straight D2. Why didnt it smoke today on pure oil?
Im thinking it bought some nicotine patches.
Also, new oil will smoke as it is condensed and will flow through the injectors like warm honey. There might be residue left over even after running the D2. Is it a constant thick black smoke or sporatic whiffs of smoke? Try using a fuel additive such as howes mean cleaner etc and see what that does. Best of luck :thumbsup:
