Mityvac to suck out the last quart of oil

I have owned two Hyundai products with the 1.6 Gamma engines going on 10 years. Shortly after buying the vehicles I learned the oil capacity is 4.8 quarts total.

Pulling the car up on ramps to drain the oil allows just under 4 quarts to drain. Hyundai decided to place the drain plug at the front of the pan for unknown reasons.

I use a Mityvac and long clear 1/4" hose to suck out the remaining quart.

These engines already have a lot going against them and leaving one dirty quart in the pan most likely adds to their early demise. Also what proper Bitog'er would be able to sleep at night knowing they left a dirty quart in their engine?

Is anyone else doing this?
 
I once owned a Hyundai Elantra Sport with the 1.6 turbo. Drain plug was on the front and required the car to be level or with the rear of the car higher than the front. I would drive it up on ramps and place the rear on jack stands.
 
Have you ever taking the oil pan off to see what's actually in that last bit of oil? Seems that would be a much better way to assess the "dirtiness" rather than to try and pump the rest out.

Every Bitog'er that changes their oil filter every other change does this. Not saying right or wrong, just saying.
 
I would spend more time dragging out jackstands and getting the rear of the car high enough to make a difference in the oil drain than it would take to suck the extra quart out of the pan. I have given thought to a shop with a lift changing the oil, perhaps the last quart comes out just fine when its level. I have never had a shop change the oil in any of my cars, ever.

I have never attempted to drain the oil through the dipstick tube. I would imagine it would take a long time. I still have to access the underside of the engine to change the filter... which I change at every oil change.

Why would you allow a whole dirty quart to remain in the engine? That's 20% dirty oil right off the bat at a fresh change. The last 20% sucked out looks the same as the first 20% that came out when I pulled the drain plug.
 
You are overthinking it. Pick an oil and do an UOA and see how many miles its good for with the extra quart left in the sump. Problem solved. I know that my PUP oil is EASILY good for 5,000 miles with extra quart left in the engine.
Not changing your oil on time what will lead to an early demise. You are overthinking it.

If you use a MityVac to get the last quart, why don't you just suck out all the oil with it?
I agree having the drain plug in the front of the pan is hardly optimal...

Would it be possible to drain the oil while the car is parked on an incline? It might depend on how accessible the drain plug is and some other factors.
 
I can see that I am the only person in the Galaxy that uses a Mityvac to pull out the last quart through the drain bolt hole. I posted what works for me and I wanted to know if anyone else does what I am doing. I don't own a fluid extractor and you're nuts if you think changing 4 of the 5 quarts is a good idea.

Tell me why is it a bad idea?
 
Alright to avoid being rude to OP let me explain my process. The reason that I and many here use Mityvac to extract the oil is because we just suck out as much as we can and if the oil filter is on top pop that off real quick. In and out in 5 minutes. In my case my filter is on the bottom so I change it every other oil change.
Again almost every one here uses the mityvac to save time and headache.

Your left over oil concern. There is an ENTIRE section of this forum dedicated to UOA. I sent my oil out for UOA.
I know for a data and evidence based fact that my oil is good for X amount of miles has Y amount of TBN Z amount of fuel dilution N viscosity and so on.

So I have lab proven data that says that that extra quart left over does ZERO harm to my engine and I just have to change my oil 700 miles sooner.

I salute you for your dedication to taking care of your car and I envy that you have the time and the physical ability to do so.
You may be the only person in the galaxy to do so but you are doing what you love and it gives you a peace of mind.
I left that extra oil in did UOA and have my own piece of mind.
Almost every one who uses mityvac does so with the express purpose of saving time.
It is your car and there is not wrong way to enjoy it. Except for Bob!
Bob is an a-hole who put neon underbody light on his car. Its not 1998 Anymore bob, Fast and the Furious is not cool anymore.

Doubtful.

I own a Porsche Cayman.
The engine is between the rear wheels.
I have to back up the car onto one of the two sets of Rhino Ramps that I own.
Then, I use two jacks to lift up the front end of the car from the jacking points, in order to level the car.
Then I can drain the oil and change the oil filter cartridge without issues of having extra oil left in the motor.

You could do that.

Or, you could do what I do it my Alfa Romeo Stelvio.
I drive the car up onto all 4 Rhino Ramps at one time.
That way the car is level.
Then I can remove the under body tray, and access the drain plug and oil filter.

You could do one of those two things, and not have to do weird things with a brake fluid flushing tool through the oil drain port.
