How many oil tests have we seen where an engine was fill with oil "X", run for a while to lubricate everything, drained of its oil, then run at high RPM until it seizes up, right?

The questions is, do you trust your oil selection to run your engine for 5 or even 10 seconds at idle once your oil is drained? Not hot, not high RPM, just idle for 5-10 seconds after oil drain.

This isn't "let's see who's an idiot", or "let's see who knows it all." I want to hear what you have to say about the risk, I want to learn.

Thanks,

I very touchy question and one that leads to angry people and better not answered to each their own I say you believe as you want as long as you feel good about your selection leave it be.

 

I don't remember what I had in the crankcase at the time I think it was Quakerstate 5w30 but I had a 87 escort that had a bad oil filter on it blew all the oil out of it at highway speed parked it for two months and refilled it and changed filter not a problem nothing

 

If I had a beater I would try it. I wouldnt try that with a 6,000.00 cummins engine tho. I've watched motor blow vids that lasted a couple min with no oil or coolant at full throttle. I would think no matter what oil you use today 5-10sec wouldnt hurt much at all.

 

I wouldn't do it to my truck on purpose, but I doubt it would hurt anything if I did it by accident.

 

We had a '67 Camaro I put DuraLube in. Wife drove to parents, bottomed out on a big dip, damaged oil pan, lost all oil (yes all) and then finished 70 mile drive. I repaired pan, put new oil in it and it drove fine for years. Couldn't believe it myself. I use DuraLube in every vehicle now, may have been "freakish luck", but why chance it.

 

Well, with the limited number of replies, it's hard to actually get a concrete direction or consensus. Let's add some details to see if more replies come in.

Everyone that changes their own motor oil, knows the mess of the dripping old oil when removing the oil filter. Seems there's just no way around that part of the job; use plenty of rags and park your truck off the driveway for a day or so to allow the spilled oil to stop dripping.

OR,

While the drain plug is still removed, start your engine for a couple seconds and shut it off. An adequate amount of the oil will be removed from the filter allowing for a clean removal.

Will that moment of not circulating oil actually cause a failure? Will it begin a wear point that new oil will not correct? How long does it take your current oil to actually circulate after a cold start (after several days of being parked)?

I'd like to hear if the steps below are the most stupid thing you've ever heard, or if it actually would do no harm.

1. Start engine, let oil warm (and coat all necessary parts), turn off engine
2. Remove drain plug and wait a few minutes
3. Briefly start engine then observe more oil coming out the drain hole
4. Remove and replace oil filter
5. Replace drain plug
6. Add new oil
7. Start engine and confirm oil pressure without leeks.

I look forward to hearing what many of you have to say about this.

Thank you,
Robb

 

New pig mats.. I use them all the time and they suck up about a quart of oil if not more. I could change the oil in my kitchen and not have to worry about and oil on the floor.

Never in my life have I heard of starting you engine after draining the oil to get all the oil out. 95% of it all flows back to the pan anyway.

 

WTF is this????
Why????

Getting paranoid about leaving any old oil in the engine after an oil change is not need nor should it be worried about most change their oil too often anyway.

 

that sounds like a bad idea furthermore I don't really think you would pump the oil out of the filter. without the sump pick up submersed in oil it will have air in the pick up tube causing it to cavitate and not pump anything. If your worried about oil on the frame and such get some cardboard in there to deflect the old oil
