Changing Oil

I recently changed the oil on an old lawnmower nine times to remove the dark sludge and deposits within the engine. I have a 1997 Accord, and if the oil is dirty when I check it, should I change it repeatedly until it is clear?

I haven't drained the oil yet, so as of now this is hypothetical. Thank you.

You would be wasting ALOT of oil.

They make engine sludge cleaner that will flush it out with a oil change.

I never believed this stuff worked until I saw what was coming out my oil pan when I got this done.

It would be very difficult to get the oil to be perfectly clean unless you sit there and let it drain for hours.

your car has an oil filter and i'm sure was run alot more than the mower. also, the degree of blow by which contaminates the oil in an air cooled small engine would never be accepted in an automotive application. other factors including the quality and location of the air filter come into play.

I've owned more used vehicles than new ones but don't remember having any problems with getting the oil [after miles] to stay fairly clean. I usually change the oil shortly after purchase and if it gets black in short order, I'll change in 1,000 miles or so and maybe use a quart of cleaner prior to changing.
