oil change, obsessive? OCD?, maybe normal?

My reasoning behind that is I have 2x the opportunity to remove crud from the engine as letting it settle lets everything drain to the pan and drain when the plug is pulled. THEN I add clean oil and filter, fire the engine to suspend what crud is left in a clean batch of oil and a clean filter that will work more efficiently than a dirty filter (less chance of bypassing the filter because of it not flowing and bypassing the filter. So I am getting the benefits of the initial crud draining and then the removal of more contaminants thru suspension in clean oil and a new filter..

So some awesome reading here. Its not so much about the oil as it is the filtration system.

Let's ask this question. What are you changing the oil at 3,000 miles? Why not 1,000 miles? Why not 5,000 miles? I think you've been sold on 3,000 miles which was a thing 25 years ago and mostly a thing marketed by the oil companies and oil change shops across the U.S. to get more customers more often rather than need.

If you are that worried about crud then create a bypass oil system like the ones you linked. The Blackstone article even gave an example of a truck going 1,000,000 miles without changing the oil.

I'm an engineer...as such, I always follow the engineers' recommendations as shown in the owner's manual - for any type car I have ever owned. My 1983 Porsche went to 550,000 miles. Original engine. Oil change recommended interval was 8000 miles. And that was with conventual oil.
My Corvette get's its oil changed when the Corvette monitor says so...I use the best oil filter I can find.

Yea, a bit overboard. On my non-dry sump cars over the years...I would just buy one extra quart of the oil I planned to use; and after draining the old, drain bolt still removed, I'd pour that extra quart in the motor to flush as much of the old oil out as I could. I would watch it drain out and it definitely would go from dirty to clean as it drained.

Do this test:
Get you daily driver hot. Drain the oil and place it into a container. Let this sit for 2 days and then pour it into another container. On the bottom of the original container you will see a layer of goo for a lack of a better term. If you are not not getting you oils hot before changing it, some of this is not leaving your engine during oil changes.

Absolutely overboard!
Once a year or about 6k miles using Mobil 1 fully synthetic oil and Wix XP filter.
What is important is to top off the oil level which replenishes old oil detergents with the new detergents. I top off when my oil level reaches 3/4 and add until full. I never overfill.

i have put 23k on my z06 in the last 9 years, and that included a round trip to st. louis, mo from houston, tx. that equates to less than 3k a year which is less than the recommended but it's the time that is why i change it once a year in the spring before our club does its 'tour de fluer' to central/west texas. i started using amsoil and noticed that the stick stays clearer longer through the year.

I think you should indulge your OCD with actual measuring. The best thing would be to run a bunch of instrumented trials and tear down the engine(s) afterward to examine bearings, rings, etc. but that's a bit much. However, you could realistically use a place like Blackstone Labs to analyze your oil and make adjustments accordingly. That would provide a bit more method to the madness.

Oil Change, obsessive? or just OCD? So I thought I would just throw out my oil change procedure just to see if there are any like minded auto fanatics out there that use the same oil change thought process as I do or maybe even a better way to do it. So here it goes. A 2005 Chevrolet Corvette with an LS2 motor with 95K miles on the clock. I change my oil at every 3K miles. I will NEVER be caught waiting until 7500 miles, or 10K miles, or 20K miles or changing my oil once a year nonsense that you see in commercials. The oil viscosity tech may have changed but we have yet to discover "self cleaning" oils.
I started a bit differently this time by letting the car sit for a week without the motor turning over at all to let everything settle to the oil pan. I haven't done this before because it really isn't practical as this is a daily driver.
So I get the car up on ramps without starting the motor. I set the parking brake and pull the oil plug and oil filter and a thick black dirty oil pours from the oil pan drain and you can feel the micro carbon grit in the dirty fluid. The DIC read "37% oil life" after 3K miles this oil change when it normally reads "50% oil life" in previous oil changes. I change the oil at 3K miles regardless of what GM or my DIC demands.
Next step is to replace the oil plug, screw on an inexpensive STP oil filter, and add 6 quarts of basic STP 5W-30 oil, start the engine and let it idle until the oil comes up to temperature and then shut the car off to let the "first oil change" as we will call it settle to the oil pan once again.
I again jack up the car, crawl under to once again remove the oil plug, oil filter, and wait until the last drop of oil falls from the oil drain. This time the oil comes out cleaner than the old oil and even cleaner than in past "first oil changes" and i think its because the old oil in the car got the opportunity to settle to the bottom of the pan for a week.
So last step in my oil change process is to button the bottom of the engine back up and this time add a top of the line oil filter and refill the crankcase with Mobil 1 5W-30 synthetic as the manufacturer recommends, put the car back on the ground, fire it up, let it get to temperature while looking for leaks, shut it off and then read the dipstick. I then slide a piece of clean cardboard under the car and come back in an hour and look for a leak to show up on the cardboard.
Is that all too much? is it crazy? is it obsessive? is it OCD? or are there OTHER car fanatics out there that have a similar procedure? a similar love for the care of their autos?
Do you have any similar oil change processes or ideas you want to share? and opinions on this procedure? my madness?

So over two weeks of driving so I figured IF there was any crud left over from the previous oil change anywhere in the engine it would certainly show up on the stick after two weeks of driving. After looking at the wipe off after coming home from work, I am satisfied with my oil change process and will probably continue to stick to it.

About ten years ago, using Mobil 1 decided would run my GMC Envoy down to zero percentage on the oil life monitor. The monitor finally reached zero at about 12,500 miles. Sent an oil sample to Blackstone. Their analysis indicated all was well. Included in the report was a notation, suggest you extend your next oil change interval another 2,000 miles.
40 posts in this thread of which 35+ disagree with 360s oil change procedure. Seems to me he is off track. No matter the consensus, am confident there will be no change.
