Oil Question

[tbone]

Has anyone noticed that even when changing the oil and filter, the oil is slightly darkened from leftover oil in the engine? In other cars I've had, the oil is perfectly clean. So clean that it's hard to read the dipstick. There must be some oil in the motor that doesn't drain out? Yes, I let it drain for 10 or more minutes and no, I don't have sludge issues.

I do not have that symptom, my oil is clean even after several weeks after a change.
Might want to try a flush and let it sit overnite to drain.
I have changed the oil where it sits overnight with the drain pug out.

[tbone]

I'm not saying it's dirty, just not 100% clear.

I let mine drain overnight you be supprised at how much will seep over time.and yes it doesnt seem long to kinda get dark looking.and i use mobil 1.

[tbone]

I'll try it overnight.

I'm nervous about flushing the motor and losing a gasket.

I usually change my oil with the engine warm. It pours right out and less residue.

[Bradley G]

It does not look clear pouring out of the bottle, it has a yellow tint.

Of course. It just is a little dark right away.

The only way to do it unless you want a dry start. Not good!

If your going to do a flush cleaner take the pan off after and scrape the gunk off or it will clog the filter then bye bye motor

Do you drain it hot, so that the detergents have time to work and the viscosity drops?
Sorry, you probably already do this^^^.
IDK do you remove the oil fill cap?
What filter are you using?

All engines will leave a certain amount of oil in the engine. A trick i use sometimes is to "burn" a 1/2 or full qt of oil. Let it drain as normal and then pour that extra oil through the engine with the plug still out, the cold clean oil will help float out the last bit of hot dirty oil that always sits in the bottom of the pan no matter how long you let it sit. It does make a significant difference in the oil looking dirty immediately after a change.

The only way to get ALL the oil out of your engine is to tear it down every oil change.

The little bit left will have no bearing on the oil you add, filter or anything else.

Drain the oil when warm and you'll get most of the oil out. Make sure you change your filter also.

:agree::nworthy: couldnt have it said better

^^^what fastblackmerc said^^^

The TINY amount of oil left after draining is of zero consequence. Waiting more than 10 minutes is unnecessary. If the oil has slowed to individual drops, that's more than enough time.

I just don't understand why, when I change the oil in my wife's Explorer, the oil is perfect, but not so in the Marauder. I think that about 1/2 quart gets stuck in the engine in passages, etc. Not a big deal, but.......

I think it's best if you remove the engine and let it soak in degreaser in your upstairs bathtub and use a spounge to gently caress the oil from within.

and dont be afraid to jump on in, nakie

just dont tell the wife.

link dont work

The crank, oil passages, lifters (pads) and timing chain tensioners ALL have oil left in them not to mention low spots in the heads, block and pan!!:cool:

You will get 95% of it in a few minutes draining it hot so don't waste time trying to get it all....it ain't gonna happen and as stated before inconsequential!!:beer:

This still doesn't explain why some cars have perfectly clear oil after a change and some do not. But thanks for the input.

[Bradley G]

I really wouldn'y worry , you are gonna have to rebuild your junk pretty soon anywho.:P

The way the engine is designed makes the difference. A big difference can be made on how the pan is shaped and how thick the slug that is spot welded to the inside of the pan for the drain plug threads is. How dirty the oil that was drained plays another factor.
