What is a windage tray used for?
What is a windage tray used for?
The windage tray keeps the windage around the crank from the oil in the sump area. It allows the oil coming off the crank to easily enter the sump without the windage affecting the scavenging of oil already in the sump.
Which oil additive helps reduce the change in the oil’s ability to flow as the temperature of the oil changes?
viscosity index improver

Where is the API Service Symbol located?
Technician A says that the API service symbol is located in the engine bay to ensure the correct oil is being used.
Can you mix synthetic and regular oil?
Yes. There is no danger mixing synthetic and conventional motor oil. However, conventional oil will detract from the superior performance of synthetic oil and reduce its benefits.
Do some engines have more than one oil drain plug?
Some vehicles may have more than one oil drain plug, and some vehicles may have nearby plugs for draining other fluids. If in doubt, consult a service manual before proceeding. Next, locate the filter. In this case, it’s to the left of the oil pan.
How often should I change my oil drain plug?
If you torque your drain plug properly every time during oil change, your drain plug should last the life of your engine (or oil pan), period. I have yet to strip one single drain plug in over 20yrs of servicing. Q. Same here, 35 years of changing my own oil & never replaced a drain plug!
What does the W after a rating in 5W 20 signify?
The “w” in motor oil stands for winter. The first number in the oil classification refers to a cold weather viscosity. The lower this number is, the less viscous your oil will be at low temperatures. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil.
Should I check my oil when the engine is hot or cold?
If checking the oil yourself, make sure the car is parked on level ground and, with most cars, the engine is cold, so you don’t burn yourself on a hot engine part. (With some cars, the automaker recommends that the oil be checked after the engine has been warmed up.)
How much oil is too much on dipstick?
In most vehicles, the dipstick will have low and high marks that indicate the oil level. If the excess oil is just 1-2 millimeters above the fill line, this shouldn’t be cause for concern. However, if there’s a quart or more of extra oil in the engine, it’s best to remove it.
What happens if I put too much engine oil?
Engine damage – Too much lubricant in the system can cause pressure on the crankshaft to increase. Overflowing engine oil can also lead to bent engine rods and collapsed valve pipes. Spark plug fouling – Excess oil can find its way into spark plugs, which will then need to be replaced.
Can I add oil to a hot engine?
Yes, you can add oil to your engine while it is hot. Cold oil will not hurt a hot engine. You should check your engine oil when it is cold, before you start the engine. Hot oil expands a bit and the dip stick will have oil splashed all over it from the engine running, so your reading won’t be exactly accurate.
How long should engine cool before checking oil?
We recommend checking the oil level either before turning on the engine or 5 to 10 minutes after shutting down so you can have all the oil in the oil pan to get an accurate measurement.
Should you let engine cool before adding oil?
Your engine should be cool. If you’ve just driven your car, wait for 5-10 minutes before you check your oil level, or check it first thing before you use the car.
Should you run engine after adding oil?
Does the engine have to be running when I add oil to it? No. You need to turn the engine off, and wait 5 minutes before checking/adding the oil.
How long can an engine run without oil before damage?
30 minutes
Can I just add oil to my car instead of getting an oil change?
Dark colored, cloudy or gritty textured oil is a sign the lubricating components of the oil have been exposed to heat for too long and needs to be changed. Adding oil instead of an oil change at this point could cause engine issues. This used oil needs to be removed to allow new oil to lubricate your engine’s parts.
Can you just pour oil into car?
No, you can’t just pour in new oil. A car engine usually takes 5 quarts, but some takes only 4 and 1/2 quarts of oil or 6 quarts. Check the car owner’s manual to find out how many quarts your car takes. Then pull the dipstick out to make sure the oil level is up to the crisscross line.
Can you add new oil to old oil?
As long as you are using the same weight oil, it will mix up and you’d never know it. Continue to change your oil at the specified interval and you should be golden. Usually when changing the oil you won’t be able to fully drain the old oil anyways and the old and new oils will mix, like it or not.
What happens if you never change your oil?
The most common issue is that the parts in your engine will become too hot. This can cause the engine to run less efficiently, and as time goes on, it can cause the engine components to warp and wear out. Eventually, if the oil is not changed, the entire engine will shut down and have to be replaced.
Will an extra quart of oil hurt?
An extra half a quart of oil in your crankcase is not going to do any harm to the engine. If the crankcase were seriously overfilled — say, more than a quart — then the spinning crankshaft could come into contact with the liquid oil, and churn it up.
What happens if you overfill your oil by one quart?
TOM: When you overfill the crankcase by a quart or more, then you risk “foaming” the oil. If the oil level gets high enough, the spinning crankshaft can whip the oil up into a froth, like the stuff that sits on top of your cappuccino.
Will overfilling oil hurt engine?
Even if you have changed the engine oil in your car multiple times, there is always the chance that you will accidentally overfill it. Overfilling the engine oil in your car can cause serious damage to your internal engine parts and eventually lock up your engine.
How do I know if I overfilled my oil?
The most common overfill engine oil symptom is white smoke with a blue or grey tint. You may find your car emitting too much white smoke which is the result of burning an excessive oil that creeps into the combustion chamber. It is one of the most visible overfilled engine oil vehicles.
How do you fix overfilled oil?
When you locate it, put a plastic oil pan—it’s different than you car’s oil pan—under the oil plug. Use your socket wrench to start loosening the oil plug. You want the overfill oil to start trickling out slowly. Let it drip until you think you have drained enough oil, then tighten it back up.
How far can you drive a car with too much oil?
10.000 miles
Can you drive a car with overfilled oil?
If the level of oil on the dipstick is an inch or more above the recommended fill level, then your car has been overfilled and should not be driven again until oil has been drained from the vehicle; otherwise, you could cause serious damage to your engine.
Why is overfilling oil bad?
Overfilling engine oil can raise the level of oil in the pan to the point where the crankshaft starts to make significant contact with the reservoir. At that point, the engine can starve from lubricant to the degree that serious damage is often the end result.
Can too much oil cause a blown head gasket?
Excessive consumption of oil can be caused by a rupture in the head gasket. Oil consumption can be caused by other things (like worn piston rings) but if your car is going through too much oil, a blown head gasket could be the culprit.
