Mityvac to suck out the last quart of oil

[Bailey28]

LOL!! I don't have any neon... never had any neon all the way back to 1983 when I got my license.

I do 3,500 mile OCI on the Hyundai turbo cars with the forward facing drain plugs. I am confident I have removed almost all of the oil from the pan based on the capacity of 4.8 quart refill with filter. I install 4.8 quarts and the level sits right on the full mark.

Shhhh, don't let the dealerships, quick oil change places or Scotty K get a hold of this top secret info where one dirty quart out of five is acceptable. Imagine their profit margins shooting sky high based on this shocking revelation! Shorting every change one quart. It will add up to raises for everyone there along with pizza parties on Fridays! Jiffy Lube can even advertise "Leave all but one quart behind"..

All sarcasm aside I never have sent my oil to analysis. Never thought of draining it through a fluid sucker from up top. Been crawling under the car taking the used petroleum bath since about 1983. Coolant and ATF baths upon occasion also. It's just what I do.

Well I live where the air hurts my face and I would have to be scraped off the concrete in this weather if I tried it.

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.

Uh isnt a mityvac a fluid extractor?

 

[JeffKeryk]

I would not leave a quart of dirty oil in the sump. I would just suck it all out via the dipstick tube or drive it up on ramps and then use a floor jack to lift the back. You can lift from the middle-back or just one of the rear jack points. Of course Jack stands are a must.

And yes, a MityVac is an extractor. Even works on EVs...

 

[KrisZ]

Don’t use the ramps.
I always jack up one side to give me enough reach to the drain plug and then once the oil is draining, I lower the car. Works quite well and gets all the oil out of the pan.

Perhaps look into a drain valve, it will make the draining much easier and you don’t have to have the car so high up because you can operate the valve with one hand.

Ah! I see where the confusion lies now... I use the little Mityvac hand held MV8000 to pull out the oil. Not the large one shown in JeffKeryk's post.

Just out of curiosity how long does it take for that large Mityvac to suck the oil out of the pan? Pan's vary in capacity so lets say about 5 quarts?

Depends on the oil temperature if it's pretty hot a couple minutes if it's cold 5 to 10

Every Bitog'er that changes their oil filter every other change does this. Not saying right or wrong, just saying.

Except there isnt any where near a quart left inside todays tiny filters.
More like 4-5 tbsp.

But we are all smart people over here so we don't buy new cars with direct injection that washes out the engine rings and cvt transmission that spit out their belts once a week.
We all drive 5 liter pushrod engines and manual transmissions.

volume depends
. my upside down subaru filter.. maybe 4 oz (filter base toward ground)

A ram hemi a vertical filter with base pointing up and the oil above it .. well over 16oz.

As @Rand says, get the oil hot. I use the dip stick as a measuring guide for the MityVac tube. 5 quarts takes a few minutes. Far faster and cleaner than jacking the car, getting tools and wrenching, and far less messy. I swap the filter every other service, or even 3rd, but don't tell anyone.

I used to be the biggest naysayer, but now I love my MityVac.

Yeah, if you want to suck out the oil, use a large extractor like JeffKeryk posted. These work very well and are useful for all sorts of other fluids, not just oil.

There are a lot of great oils out there that are designed go longer intervals so if you’re running one of them and changing it every 5-6k then it’s not as if any residual left over is really all that bad anyway. It would drive me crazy having to do extra work at every oil change. When I had a C5 Corvette a lot of the guys on the forums would talk about how they had to jack up the rear end in order to get an extra quart of oil out but I never bothered. I even went as far as 9000 miles on one OCI, which was 2000 miles beyond the point when the OLM counted down to zero. My Wearcheck oil analysis showed that sample to be perfectly fine and could have even gone longer.

So here’s what I would suggest you should consider trying. Do two 5k intervals in a row where you don’t try to remove the extra quart and then take a sample of the second run and send it off for a UOA. I bet it comes back looking good.

Here is the oil pan of a Chevy LS 6.0. There is actually a section of oil pan that is lower than the side mounted oil plug, so no, you won’t get every once on this one. Also here is a shot showing the baffle bolted in place that would make it dicey to get a plastic tube in there, made worse buy the fact the dipstick tube comes in at nearly 45 degrees. After 16 years and 250,000 miles there was a thin layer of mung on the bottom section of the pan. It cleaned up with a paper towel and some Simple Green. I’ll post the photos later. Gotta go.

I also use a fluid extractor for one of my cars. It would be a good solution for your situation. Not only is the fluid extractor quicker than the drain plug method, it is also less messy.

Another solution would be as others have suggested here, and lift all four corners of your car, so the oil pan is level, or slightly inclined with the rear higher than the front. This may be a good solution, especially if you do other service of your car at the same time as the oil change. For example, this method would make it easy to quickly inspect brakes.

Plenty of other ideas suggested here, but some seem unnecessarily complicated.

I don't care either way, but to the OP's point, there is dirty oil left in his engine. And besides being vehicle filter size/orientation dependent, watching a customer shop of mine who crushes all their filters, there is a lot more oil than 4-5 tbsp in even the smaller filters when the media is compressed.

Lots of square rooting about ramps and stands … Just don’t …
Use an extended life synthetic changed at normal intervals …
Stick with same lube …

The rest of the engine holds more oil that whatever is in that filter so changing the filter still leaves dirty oil in the engine.

My V6 honda and my V8 titan use the same tiny filter - the amount in thats in it isnt much more than a teacup.
I dont crush the media but I cut every one and it amounts to squat.

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?

Fumoto valve and then just reach under car on ground, no ramps.

But what if my hobby involves sending oil in for analysis and worrying about absolutely inconsequential things?
