Looks like you're getting coolant mixed in with the engine oil. Not good. Receipe for disaster. Could be a bad head gasket and/or cracked head. Do not run engine any longer until you have it checked out. Coolant in the oil will destroy bearings in a short time.
Check your dipstick to see if the oil has a milky appearance. If so there is coolant in your oil and you probably have a blown head gasket. If the oil looks normal and the fluid you described as brown looks the same as the color of your motor oil ( a bit dirty ) you have either blown a head gasket or craked the head. If your vehicle has an oil cooler you may have a leak in the lines to it or a leak in the cooler itself. There is also a type of refridgerant ( from your ac system ) that will turn brown when exposed to air.
It could be the cause of the knock only if the gasket was bad and leaked out almost all the oil.
If your car is running out of oil, I would be extremly worried because if you car does not contain any oil then your engine would seize. If you are changing your oil, you need a new oil filter and you rub some new oil on the seal of the new filter so it does not melt to your car. Make sure your bolt that hold your oil in your oil sump is still there. Change your oil after 6000 kilometers. If your oil is still fairly clear your good.
How do you reset the 'oil change required' message on 2007 Lincoln Town Car???
The red oil light means you car is low on oil, or there is a problem and should be checked.
yes i do believe.
Yes.
Depending on the wrong oil used it could shorten the life expectancy of the engine. We need more details.
The answer to this depends on what kind of oil you are talking about. If you put a heavier weight oil (like 5 weight) in your car instead of say,30 weight, it will cause your car to act sluggish in the cold weather because the oil is thicker. If you put a lighter weight (30 weight ) in a vehicle that needs a heavier oil, the car will still run but not as well as using the correct type of oil. If you put transmission oil in your car's engine oil pan by mistake; you should empty out the oil pan immediately (when the oil and car are cold) and flush it or refill it with the correct oil as soon as you have realized it was the wrong oil.
One reason why oil will drain out of a car after filling it up could be a hole in an oil filter. The car will need to be fixed before being driven.
The oil will be cloudy and look like chocolate milk.
If you drive your car without oil and it dies, your engine has seized. Time to replace the engine or the vehicle.
If the car does not smoke badly this may mean you are using the wrong weight motor oil. Use the proper weight oil that a dealer will recommend.
Yes it does.
Oil in water emulsion.
blown head gasket
Drive it to the mechanic. You have something wrong and that is what the car is telling you. Oil, water, something is not right.
