Has anyone else tried this?

Hi, I previously posted about a Saturn I bought w/ 270K on it that burns oil.
After draining the oil for a about 30 min., I left the drain plug out and poured in a quart of some old (but unused)oil that was given to me. The oil came out pretty nasty looking. So I poured through a second quart, then plugged it and filled with 10w30 Mobil 5000 w/ 20 percent MMO.
In 17 years of changing my own oil, I have never seen my oil this clean. It's so clear I have to pull out the dipstick 10 times to figure out where the oil level is (doesn't help that the oils so thin that it drips off like water).
I have a '04 Expedition w/ 70,000 miles. for the last 3 oil changes I've gone about 10K w/ AMSOIL 0w-30. Prior to that, I was going 5K w/ AMSOIL 5w30. I switched to AMSOIL at 3k.
Usually after an oil change, my oils already looking a little dirty pretty quick. I never have any trouble seeing where the oil level is on the dipstick even after just 10 miles or so.
Next time I change the oil on my Expedition, I'm going to flush through 1 quart.
Maybe this just rinses out the oil pan but it sure made the Saturn's oil look good.
I'm guessing that little bit of old oil left behind probably doesn't matter as long as it's not 50,000 miles old, but it's nice to see such clean oil in my car.
Has anyone else tried this?

I had the oil pan off my Buick recently. After mopping out the cup of old oil and putting fresh oil in, it was very clear on the dipstick.

It's possible your Saturn had a really dirty oil pan, and you cleaned some of the gunk out with fresh oil.

When changing the oil in any engine, you always leave oil in areas such as the cylinder head. By pouring in clean oil and letting it flow out of the drain pan, one is removing more of the dark/dirty oil that was just sitting there(over the cylinder head/rockers) unable to be removed until fresh oil is poured in and washes down more of the remaining oil. That's all!

I don't do this myself but I have heard/read of others that do.
One could do even more to insure that fresh oil is in the engine.

Talked to fella who was waiting for his car being serviced at a FORD dealership. He told me that when he changed his oil(himself) that he would drain the old oil, pour in fresh oil, run the engine for several minutes, drain the oil and again pour in fresh oil and replace the filter. Call it a day! 2 oil changed for one 3000 mile OCI. He also mentioned to me that the last car he did this to, he got 150,000 miles on the engine...I'm thinking to myself, BFD!...I didn't say anything.

I've put on 200,000 and 300,000 miles doing 3K-5K OCI with any ol' oil(store or name brand oil on sale) by just draining/refilling and a filter. Often changing the filter at every second OCI.

I usually give it a little shot of fresh when it's done draining and plug still out. Just a little slug.

As for refilling and essentially wasting one sumpful of oil, well I'd probably do it if I had an abundance of free oil. Would clean out a little more of the old stuff, but not worth it on my dime.

If I get even 95% of the old oil out with a regular oil change, I call it good enough. I never pour anything in just to flush whatever is left out.

I do my filter changes separately, so depending on the OCI, it might see one OC, or as many as 3. Just depends on where the OCI was at when I changed the filter, and the duration of subsequent OCIs.

Its not the normal way of doing things, but when you have a burner you can throw some of the 'rules' out the window and wind up better off for it.

Your right Spyder. People have to do what makes them sleep well at night.

No harm in taking a qrt. of Supertech (or any other cheap oil) and pouring through after oil drain to clean out any remaining old oil in the pan .

When I do a pour flush, I do it with MMO
