Hello, I have a 2003 Honda Accord ex with the 2.4l engine and I just hit 199k miles but am due for my oil change. The car burn oil (I wanna say 1 quart for about 600-800 miles) and the oil is very very dark. Should I get an engine flush to clean it out or just do an oil change?

If I don’t respond till tomorrow night it’s bc I work 10 hours then got school after.

The burning of engine oil is not connected to a engine fluid flush. Your oil is black because you have blow by. That is carbon from burnt oil in your motor oil. This is why you are adding so much oil every 600 - 800 miles. Tests : check by the muffler to see if you have black carbon aka soot on your rear bumped. If yes that is a sign your car is burn engine oil with gasoline on the power stroke. Second test is to purchased a cylinder leak down test kit and a air compressor to verify which cylinder(s) are compromised. Use this link for information on how to conduct the test. https://www.mobil.com/en/lubricants/for-personal-vehicles/auto-care/vehicle-maintenance/how-to-do-a-leakdown-test#:~:text=Remove the oil dipstick%2C radiator,indicate where the problem is.

Before you tear down the engine, pinpoint where problems are by using these three steps to do an engine leakdown test.

In practicality, nobody is going to tear down an engine on a 21 year old Accord and rebuild it. This is prime “just keep adding oil” kind of vehicle. That said, agree with the answer to the question, an engine flush is not needed nor will it help.

Do the work your self, the K24 has a huge following with tons of information on how too, would be a good learning experience.

Which also may mean the motor is toast depending on how bad the scarring is on the cylinder wall

You all are bolder than me haha. But I do stand corrected, if OP is up for pulling and rebuilding an engine, it’s a good project to learn on.

Some poor dealership is offering $1k trade in not realizing Motor is toast

#

After seeing the condition of the oil and how long it got after 600 miles recently and how poor it’s performing it’s giving out

Sad but common for 7th gen accords with 2.4l
