  • “Maintenance” of engine oil over years (no Longlife!)

    Hello to the experts, sometimes a – quite general – question with regard to the engine oil (except Longlife oils) (the search could not really help me in answering my question) So – especially with the oil change interval you should be quite precise or strictly according to manufacturer regulation. Especially within the warranty (does not apply to me however!) It also says again and again, that especially few drivers more precisely on the prescribed Interval But what if a vehicle just stands for a very long period of time – without starting it between times (or at most every 2 months to shunt maybe) – that should be rather harmful for all components anyway. I can say that I can “drive” one and the same engine oil over 5-6 years or even more? Hazards will be as good as not. Oil is not exactly cheap and it is all 12 months if it is not used. ate (as with Ford for example) to change… well. And yes, I know, an engine damage is even more expensive… Oh yes: The vehicle should not be sold and will probably be driven again after changing the job. As soon as the car is driven more and more regularly, I would of course have a change carried out before!! I just want to hear/read your opinion about it … Thank you in advance

  • Lead battery Regenerating, Waiting, Revitalizing

    Hello together, I know there are various topics. Maybe someone still wants to discuss it again or again or to give help. After she let me down yesterday morning at 1°C, my motorcycle battery wanted to bring something to the front. I read it into the matter today the whole day. In my case this is a 12V/12Ah motorcycle lead battery about 2-3 years old and becomes 3/4 of the year 2x daily for 10km but should be generally reverberated. Well, how is it best to do this? First of all, I got an acid lifter and battery acid for a precaution, of which. I still have water. The battery now hangs with 300mA on the low-cost charger. Before charging directly after driving I measured the voltage, this was at 13,8V which really surprised me. Level corrected and off to the charger. Let’s see what I measured when it is “fully” charged. My questions or instructions skusion basis is based on the following statement from Wikipedia: “The acid density at the same time represents a measure of the state of charge. It is about 1.28 g/cm3 with full accumulator (100% charge) and 1,10 g/cm3 with unloaded accumulator (discharge > 100 %, deep discharge!) ” With corresponding graphic:charging state of a battery over idle voltage 1. If according to graphic 100% charge state are reached at 12.7V how can I measure my battery 13.6V voltage? 00% charge state? 2. If battery acid is max 1.28g/cm3 how can it reach over 100%? Shouldn’t the acid concentration have to rise to over 1.28 theoretically? 3. Can I assume that an internal cuz circuit of a cell has not occurred during the voltage measurement (approx.2V per cell)? Since the voltage alone is not a statement for an intact battery, but rather the capacity is characterized by a persistent starter battery I must probably look in the “full” charged state whether and how quickly the voltage decreases or collapses under a defined load. To do this, I would take one or two H4 light bulbs and measure how long it takes until the voltage has dropped to 10,5V. Further considerations after I have done this and not to make the contribution any longer.

  • Why is the car not equipped with a slat coupling?

    Why is the car not equipped with a slat coupling? More slats = More power transfer possible. Why such a cheap single clutch?

  • Automatic transducer – Which running performance did you achieve without interference?

    Hi, since the automatic transmissions are often attributed to a lower service life and a greater maintenance effort than manual gears, I would be interested to know which running performance you have achieved in practice with automatic converters with regular maintenance (ATF change, if necessary) without major repairs. Therefore, I have chosen the automatic converter system, because it is by far the oldest and most sophisticated automatic transmission system. In this way, it also affects the service life compared to other automatic transmission systems such as DSG or stepless variomatics.

  • Recommendation of durable plate holder

    Hello, a specialist question to the municipality: Can you recommend me a high-quality and long-lasting license plate holder? I always remove the license plate for every washing of my different vehicles and unfortunately had to find out again and again how scrapy most license plate holders are. They break easily or hardly keep the license plate after repeated opening. I have very good experiences with a product of the probably Polish brand “Intercrown” which but obviously not available in Germany. Afterwards I thought of a 3M Velcro solution, but this leads, with regular removal, unfortunately to the deformation of the plates. Do you have a recommendation for me? Greetings!

  • How much fat in achsmanchette?

    Hello everyone, I have a little problem, I drive a 2.0TDI Audi A3 from 2006. Now I have just seen that behind the brake as well as the inside of the rim everything is full of something oil-like. You can not wipe it away with a cloth, it only smears. It is sticky and dark to slightly greenish. I first thought about oil, but it is too thick for that. Hard to describe. Anyway, it is so much that the “inner” rim bed is completely covered, you can see the silver of the rim in no place. In addition, all small stones stick in it. Also behind the brake disc or the cover plate and around the axle cuff everything is fully covered, that one can no longer see the material under it. Can this, with the quantity, be the fat from the axle cuff? I should drive tomorrow morning 400km, I would only hate that if it is the Manchette. With the crowd there can not be much left in it anymore ??

  • Does the vehicle fit well into the garage?

    Hello, the consideration goes towards Citroen Berlingo. The garage dimensions are: 2,50 wide, 4,95m long and 1,95m high. The Berlingo has the dimensions: 4,41m long, 2,11 wide (with unfolded mirrors), 1,85m high. It was necessary theoretically to fit well, but you also want to be able to close the garage door and keep distances from the walls. In addition, you have to be able to get out of the car in the garage. What do you mean?

  • buy used brake sets at ebay

    Hi, wanted to ask you if you can easily buy used (runtime 2 or 3 digits) original BMW brake sets from ebay without hesitation. Where are the dangers, except that you no longer have a warranty/guarantee? Can the discs be warped or have latches, etc..? Does someone have experience because you can save a lot… So what e.g. https://www.ebay.de/itm/166669581282?…

  • After switching music goes out short

    Hello, I have a power amplifier on which also a subwoofer hangs. As soon as the music is a bit louder and I have switched on, the music goes off for about a second. This happens quite exactly when I release the clutch again. What can it be about? Thanks.

  • Air the brake.

    Hello.I have to change all 4 brakes.If I want to remove them then I have to change all 4 first or I can do this one after the other.
