So there then ... Got my twizy on Friday .. Change the oil the first thing I did. Have maybe 50km, so I changed. There was 1 liter of oil out and I poured a one liter.
And now for the most exciting result.
Oh my God! I'ts quiet. What I hear is how the enige work and the sound of tires on asphalt. But the transmission is completely quiet. It really became a big difference, even though the car is new. I think it's a bit easier to roll.
