so I don’t know I have them already 300 km with low speed 1:50 in the tank in addition not for two, no mountains etc. drove in and plötzzlich while driving jammt the thing me häds almost laid uung the track of the matures is about 10m long (I was so at70km/h as described in the drive-in pan turn up short distances, which so far always went well) and now that, meanwhile it runs again, and to the happy as before, but the running area has already got something and I’m afraid that this will happen to me again on the right road (was just heating up the road) so I hope one of you knows what I can do to avoid that.
