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.

Do you check the oil when the engine is hot or cold?
Engine Oil, Check! 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 long does a car have to sit before you check the 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.
How long should you let your car sit before driving?
Here’s how long you should let your car warm up according to auto experts: 30 seconds.
What happens when engine oil gets too hot?
Thermal breakdown is among the most damaging effects, and occurs when a car’s internal heat causes a chemical reaction in the motor oil, which causes the oil’s viscosity to change. Basically, if (or more accurately, when) the engine heats up beyond a certain temperature threshold, the motor oil will start to degrade.
Can you check the oil after driving?
Refer to your owner’s manual. Immediately after driving, the oil level will appear lower, making it easier to overfill the oil. If you want to check the oil and have been driving the vehicle, wait five or ten minutes to let it settle into the oil pan before checking it.
How do you properly check your oil?
Check your engine oil weekly when the car is warm and on level ground. Stop the engine and wait a few minutes for the oil to settle, remove the dipstick and wipe it clean. Push the dipstick all the way in, wait a second, and then withdraw it and check the level. The oil should be between the two marks.
Can you 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.
What should oil look like on dipstick?
So, let’s take a close look at the oil on the dipstick. The oil should look smooth and glossy and somewhat transparent. If it has sludgy deposits or grainy particles of dirt, it’s time for an oil change. The same is true if the oil looks too thick, is too dark (opaque), and/or has a putrid rotten-cheese smell.
How long should I let my car run after oil change?
Here is a tip for speeding up your oil change – if the engine is cold, fire it up and run it for 2-3 minutes. The oil will warm up to about 100 degrees, which is not hot enough to burn you, but warm enough that it will flow easily. If the vehicle has been driven, let it sit for 20-30 minutes before draining the oil.
How much oil is too much on the dipstick?
Most engine dipsticks have a range of acceptable oil level, spanning about a quart, or 20 percent in most cars. If you have significantly more oil than the top of the dipstick range, play it safe and let some out.
What happens if you overfill oil?
When too much oil is added, the level in the oil pan becomes too high. That allows a fast-moving lobed rod called the crankshaft to come into contact with the oil and essentially aerate it. The result is a foamy, frothy substance that cannot properly lubricate the engine.
Will an extra quart of oil hurt my engine?
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.
