Oil does not register when running

Pull the oil dipstick and see what your oil level is at. If there is no oil on the stick then your oil level is low. Add a quart of oil and check it again. (give the oil at least 30 seconds after you finish pouring it to get down to the oil pan to register on the dipstick first). Then only add more if it still does not register on the stick. If the oil level is fine, then you may have a bad oil pressure sensor.

Could have overheated because low on oil, the engine may not start until the computer is reset, a safty feature which keeps the engine from damage in such cases., Take it to a mechanic to reset the computer if you think the oil being low was the main issue.

all engines burn oil, ALL!
and if you dive faster, it burns more. (rate)
you did not state the rate, here in USA we do
quarts per mile (liters are same )
1 qt/ 3000 miles is norm.
but if you dont service a vehicle , for sure every 60miles.
100km. the PCV valve will clog and the crankcase will go over
pressure, and the car will leak and burn more oil.
the dip stick hole must **** not blow.
if it dont **** , running, the PCV is DEAD !
(1960 to present same deal)

The problem you have is a cracked block. This allows water to get into your oil, and that causes the milky appearance. As you might imagine, this is not a good thing. You can try the block seal, but, there are no guarantees. Good luck. Oh, and by the way, it has nothing to do with the dip stick, just the water and oil failing to mix.

Gas in oil generally is caused by a faulty injector sticking in the open position after vehicle is turned off. The remaining pressure in the fuel rail is then slowly leaked out into the combustion chamber and seeping down past the oiling rings on the piston. This what is called "Flooding" in a carbureted engine as well, when gas pours into a cylinder that is not firing. Be sure and change your oil out soon, gas breaks down oil to where it does not lubricate properly and can cause more serious issues soon. As far as the check engine light coming on, it may or may not have anything to do with this issue. Unless, the breakdown of your oil over time is decreasing oil pressure and the sensor is registering low oil pressure. The check engine light can come on for various small reasons that do effect the drivability of a vehicle. Check the code that your ECM is registering for this light to come on.

sounds like you engine cant vent so its using the weakest point the dipstick, check your engines breathing system and the pcv valve it might be blocked, find it connected to the air filter housing with a hose , it should rattle when you shake it if not replace it.

Oil leak will not change run temp but can cause a fire.
The smoke is the oil burning on the engine. The 1st thing you need to do is clean the oil off the engine.
Next top oil off to the full line on the dip stick.Now start the engine hold idle up to around 1600 rpm for 1 to 2 minutes keep engine run and look for the oil leak. Don't get caught in any moving parts and things will be hot so be careful. Most likely from your valve cover.

Yes, When you run an engine low on oil enough to cause the light to come on then damage is being done. It sounds like you caught it just in time. I would change the oil and filter for shure as soon as possible. Then I would Change them again In a week or two. Then you should be OK.

To check engine oil level engine needs to be off, if check while engine running, oil will splash inside oil pan and all over your dip stick giving you bad reading, Check oil level with engine off and add to full mark on oil dip stick. Running engine with low oil will cause major damage to your engine. To check transmission level engine needs to be running at normal engine temp.

That can be something wrong with the oil , how long time since you change oil and filter on the transmisjon. A other fault could bee the clutch ore brake band inside the transmisjon. If you smell at the oil , when you tacke up the oil stick , the color on the oil shall bee red , if the color been brown and the smell are smell of burning , the are something wrong with the clutch.
