This could be caused by: High engine oil levels; Worn out … Under normal conditions, these air bubbles would simply pop in the oil and release into the crankcase, but very cold oil tends to trap the bubbles and turn them into … This can be confusing for people who don’t know what each color indicates. Castrol GTX High … The total acid number (TAN) is a measurement of acidity that is determined by the amount of potassium hydroxide in milligrams that is needed to neutralize the acids in one gram of oil. It does a remarkable job of reducing overall wear of high mileage engine, and also reduces oil consumption of the engine. The most common cause of this is a failure of the cylinder head to engine block gasket. Other types of assembly errors may also be seen. Symptom: Engine uses more oil than normal, and there is some smoke from the exhaust. Before your next drive has a chance to “go up in smoke,” review the car exhaust color coding below to help you determine if it may be time for an oil leak repair, an engine tune-up, a coolant check, or something more serious.

It is usually the naphthenic acids in the crude oil … Okay, just read a 2010 328i manual. Coolant (Antifreeze) can be found in more than 1 color. Oil could be leaking into the cylinders, getting past pistons that are worn or valve guides that are worn. Valve Guides: Excessive clearance between the valve stem and the valve guide allows the oil … You may or may not notice the engine … Yellow gunk in oil cap is caused by short trip driving. (Psst! If it is opaque and light brown looking like chocolate milk, there is water or coolant seeping into the engine oil. Without oil pressure, the engine can't lubricate itself, and the result is self-destruction, meaning you have to do some seriously expensive internal engine … 2. Call for a tow. The oil level is low between oil changes. It is not an indicator of trouble like the check engine light is. A Word about Engine Oil Additives. Exhaust Color Diagnosis. Resists tranny fluids. Gear Oil (Color unknown - Assume black) - Used on differential housings to seal in gear oil. I think the turbo engines use a shorter mileage number. Since the oil filler cap is at the top of the cylinder head, the oil/water settles in the oil cap, forming a yellow gunk. Depending on the severity, an oil … So, it's a pretty stern warning. Engine oil is the very lifeblood of your vehicle. Check the oil filter gasket and the oil lines located on the top of the engine.

Figure 6: Low oil supply or oil starvation doesn’t just sound bad, it does bad things inside the engine. Oil flows through dozens or hundreds of tight spaces inside your engine -- particularly in the valvetrain -- and every time it does it picks up a few air bubbles. 3. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. A check engine light doesn't mean you have to immediately pull the car to the side of the road, but it should be inspected as soon as possible. Finding the source of the leak is very important – consult a mechanic for guidance. The "w" in motor oil stands for winter. In rare cases, there may be a crack in the engine block that pushes oil out. This is an indication of coolant in the oil being burned off. There are two numbers that define the viscosity of an oil. If the check engine light illuminates, it will either blink or remain constantly illuminated, depending on the problem. It doesn’t retain its original color for long, as each heat cycle darkens its color. Wait until the car has cooled down and remove the dipstick.

The service required light just means the car is due for an oil change or other routine care. Without sufficient oil or oil pressure, the engine can wear itself out in a matter of seconds. The Kytola Instruments Oil Color Analyzer is an online instrument based on visible light absorbance (transmittance) to indicate the ASTM D1500 color value of oil. The TAN value indicates to the crude oil refinery the potential of corrosion problems. When an abnormal color change takes place, the presence of contaminants should be explored. The engine block is made of strong materials and it is difficult for it to crack. The second number is defined by how an oil flows at normal engine operating temperatures. You need to add the quart as quick as you can. Blue exhaust smoke in a diesel vehicle could still mean oil is being burned, but it could also mean the engine oil is being atomized.
