The vehicle is losing oil - that could be the problem!

If your vehicle Oil loses, can the several causes to have. An oil loss is usually made more or less large Oil stains noticeable, which can occur in the engine compartment or below the vehicle. If the loss of oil is so severe that puddles are forming under the car, you should definitely take one tow away arrange to the nearest workshop to avoid expensive damage. Then I actually like DIY exams nothing more to reach. This is often also the case when the red one lights up Oil indicator light the case! In this article we would like to explain in more detail to what extent an oil loss can be noticeable, what the reasons could be, which repairs are necessary and how much the whole thing costs.

Symptoms - loss of oil

The vehicle is losing oil - that could be the problem!

If the car loses oil, it'll do it to you, among other things oil level under the minimum, a active oil warning light and one clacking engine noticeable. If in the engine compartment in several places smeared oil is, of course, should first be determined where the oil actually is Austritt. The workshop can do this with the help of a professional engine washing accomplish. Otherwise it is also a good idea to have a Contrast media so that you can later see exactly where it is using a UV lamp Oil leaked at a hunt. By the way can the process with the Contrast media even in the case of a defective air conditioning be applied. Evaporated The coolant is inexplicably so, for example with a colored one UV contrast media for systems with refrigerants R12, R134a, R1234yf and also for hybrid and electric vehicles the cause be determined.

Causes of Oil Loss

The causes that we now name are simply due to that Engine oil based (deep black color, burnt odor, greasy feeling).

  1. Oil pan drain plug leaking
    - Especially when it comes to one Inspection in addition to the fact that oil is leaking, the correct tightening torque of the Oil drain plug was neglected - as a result, oil leaks there. However, this problem can be remedied relatively easily by simply tightening the screw correctly or, if necessary, with it Teflon tape (for emergencies) is helped. After that, of course, the amount of oil that has been lost must be replenished. Now there should be no further oil loss.
  2. Leaking oil pan
    - One leaky oil pan Occurred from time to time, especially when the mileage was high, which means that the oil leaks at this point. However, one can also more mechanical Reason exist. In any case, the oil pan must be used expanded which sometimes even requires the entire engine to be removed.
  3. Damaged oil pan
    - It can also happen that the oil pan through Contact with a curb / stone was affected and possibly a fine one Hairline crack carried away. The engine oil then flows through this crack to the floor. Maybe the screws of the oil pan were tightened too tight a crack can also arise through which the oil leaks

  4. Leaking crankshaft or camshaft oil seal
    - Both Simmerring it is about Sealswhich are intended to prevent oil from escaping on the crankshaft and camshaft. If these seals no longer work, it can Oil loss be the consequence. In the worst case, the oil will damage the tissue of the Timing belt or that of the V-ribbed belt, which results in an expensive one engine failure can result. If there is any suspicion of a leaking oil seal, a workshop should be sought. In general you have to then with Material costs reckon between 20 and 200 Euros be. Of course, this also has to total time be noted that between and eight to ten hours can last. This can result in costs between 100 and 1.000 Euros result.

Tip: This is how you properly dispose of used oil!

Other reasons can be a leaky turbo hose, a defective oil filter housing seal, a defective Crankcase ventilation and broken turbo hose seal his. But it can also be Servo or transmission oil is and no engine oil. If that is the case, they are often one defective servo pump or a defective steering gear the reason. If with one automatic transmission the seals no longer function properly, leakage can occur transmission oil also be the result.

Oil loss and general inspection?

If it's a severe oil loss acts in which the additional Drain occurs, that is a considerable lackwhich ultimately ensures that you not by the Main inspection come. If only an easy one Oil sweating is present, represents one minor defect which has no effect on whether you pass the main inspection or not.

Measures in the event of an oil spill

An oil trail is particularly dangerous for motorcyclists and cyclists. Also of course for the environment. If a lot of oil leaks while driving and it is noticed, you have to do it immediately pull over to the right. The fire department can Oil residues in the pavement with the so-called Wet cleaning process remove. So no other road users are endangered and the Environmental Protection is also guaranteed. After all, already can 1 drop of engine oil 1.000 liters of groundwater contaminate. You can take the leaked oil in the garage / parking space with you cat litter or with a special binding agent. Also one kitchen roll or Toilet paper can help. By the way: An oil trail is not always one misdemeanor. If you take care of the elimination immediately after noticing, then you usually have to do not expect a penalty. And the insurance pays usually also the elimination.

summarized the most important information about oil loss:

  • if the vehicle loses oil, you have to find out why
  • there are different types of damage (harmless to complex)
  • the car often loses oil from it Motor (leaks)
  • Stain under the vehicle can also come from transmission oil, hydraulic oil (Power steering), brake fluid, Fuel type, cooling water come (this must be taken into account when changing the brake fluid)
  • Which liquid is involved should definitely be clarified (Engine oil = Black and smells unpleasant, Automatic transmission oil (with Automatic Transmission Fluid / ATF) is reddish, hydraulic oil is reddish, Olive oil from Manual transmission is mostly yellowish)
  • if there is a lot of loss of engine or transmission, a cleaning the erfolg
  • Puddles of oil can be too high Fines to lead
  • Car can lose oil, without it dripping on the street (Fluid is then within the system and can be overlooked) - oil level therefore always keep an eye on
  • Signs of Oil loss there are puddles of oil, oil smears under the hood, little oil in the oil tank, engine overheated, clacking, etc.
  • Repair options in the event of oil loss around the oil filter by tightening or using a new seal
  • Repair options in the event of a leaky oil pan (shrunk seal) possibly using Stop Oil Loss is possible.
  • Duration and cost can be difficult without a close inspection estimate (Easily accessible seals are inexpensive to replace, if the oil pan seal has to be removed it can be more expensive to repair Hoses in the engine compartment can be more expensive, are costly complete Transmission, Engines etc.)

Stains under the car? Harmless or a defect?

  • Search for the cause only with safety glasses and protective gloves (certain operating materials such as brake fluid are extremely toxic)
  • harmlose is condensation from the air conditioning system (often seen especially on warm days)
    - it is colorless and odorless
    - As a preventive measure, the air conditioning can be switched off 5 to 10 minutes before the end of the journey (this means that no germs or mold can form in the evaporator)
  • Loss of engine oil due to leaking oil pan, defective cylinder head gasket, leaking crankshaft oil seal, etc.
  • Loss of transmission oil due to leaking gearbox input shaft or drive shaft oil seal, leaking gear oil drain plug, shift linkage, etc.
  • Loss of fuel (Petrol / diesel) due to defective fuel lines or defective fuel filter
  • Cooling water loss due to a leaking radiator or a leaking cooling water pipe
  • Servo oil / hydraulic oil loss due to a defect within the steering (Servo pump, leaky servo hoses, defective steering gear, etc.)
  • Loss of brake fluid due to leaky brake lines, leaky brake caliper, defective slave or master cylinder
  • loss of Contrast media from the air conditioning system (neon green liquid) indicates leaked refrigerant from the air conditioning system
