7 Reasons Drivers Are Pulling Their Oil Out Through The Dipstick Tube — And The One Rule The $25 Pumps Never Print On The Box

No jack. No ramps. No drain plug. The tube already reaches the floor of the pan; a 12V pump pulls warm oil up it at about two minutes a quart. The rule is five minutes of idle first, and it's why the same cheap pump gets five stars from one owner and "Junk" from the next.

Step 1Line down the dipstick tube until it stops

Step 2Red to red, black to black

Step 3One switch. Stop the second the jug is full.

Step 4Warm oil climbing the line into the jug

Before I put my name on an oil pump, I did what I'd tell a friend to do first. I found the most popular $25 12V pump on Amazon and read every review of it. All 110. Forty were five stars. Seventy were one star. Almost nothing in between.

The five-star owners were pulling 3.7 quarts out of a jet boat in six minutes. The one-star owners were watching the same pump smoke on the driveway. Same pump. Same listing. Same months.

It took me a while to see what separated them, and it wasn't the pump. That's reason four. The first three are why you'd want to pull oil out the top at all.

The car never leaves the ground. The jack stays in the corner.

Reason 1

Zero time under the car.

The jack was never part of the oil change.

Everything you drag out on a Saturday, the jack, the stands, the ramps, the creeper, the cardboard, the drain pan, exists to reach one bolt on the bottom of the engine. Skip the bolt and you skip all of it.

You don't need the bolt. You need the oil. And the oil sits at the bottom of a pan that already has a tube running into it from the top: the one your dipstick lives in.

Warm the engine five minutes, shut it off, feed a thin line down that tube until it stops, clip the pump to the battery, flip the switch. The car never leaves the ground.

"8" from my face as I lay on my back"

BobIsTheOilGuy member, on where the drain plug lets go

What a jack costs when it slips. A Mazda6 owner's jack rolled forward mid-change and went through the radiator: a tow, a $740 repair and $90 of rental car, for an oil change that never happened. mazda6club.com, "$840 Oil Change"

Reason 2

The drain plug is the only part of an oil change that ever cost anyone $902.

Steel bolt. Aluminum pan. The bolt always wins.

Modern oil pans are aluminum to save weight. The plug is steel. Every time somebody cranks it down, you, the quick lube, the kid with the impact gun, the soft threads give up a little. Nobody notices for years. Then whoever is holding the wrench when they finally let go gets the blame, writes "damaged oil pan" at the bottom of your receipt, and doesn't say a word in the waiting room.

Pull the oil out the top and the plug never moves. Not for you, not for anyone. The only drain plug that can't strip is the one nobody touches.

"They denied doing it so I ended up having to pay $902."

Forum post, stripped oil pan after a quick-lube change

It gets written down, not said. Four days after a quick-lube change, a Civic owner's car was towed off the beach with stripped threads. The shop had written "damaged oil pan" on his receipt without telling him. Estimate: $650. community.cartalk.com

Aluminum pan, steel plug. The threads that gave up.
ENGINE BLOCK drain plug height 6 mm line bottoms here dipstick tube Schematic. Tube routing and plug height vary by engine. Check yours with the Sharpie test.

The plug sits up off the floor so a rock can't knock it loose. The tube doesn't have to.

Reason 3

The tube already goes to the floor of the pan.

The Sump-Floor Draw

This is the part that surprised me. The dipstick tube doesn't stop halfway down the engine. It runs to the lowest part of the oil pan, and on a lot of engines it ends lower than the drain plug does, because the plug has to sit up off the bottom so a rock off the highway doesn't knock it loose.

So "does it get it all out?" has a plain answer: the line pulls from the lowest point it can reach, and on many engines that's below the plug. Check yours in thirty seconds. Hold the 6 mm line against your dipstick and mark the line with a Sharpie where the dipstick's tip sits. Then feed the line down the tube until it stops. It'll go past your mark.

Then measure what comes out against what your manual says goes in. That number is your proof, not my paragraph.

"Extraction is a shortcut." On a jet ski, an inboard and a lot of European engines it's the factory procedure. The tube is the service port. The plug is the compromise.

Reason 4

The rule the $25 pumps never print on the box.

Warm the engine first. Then have a switch to stop it.

Back to those 110 reviews. Reading only what people did before they flipped the switch, the five-star owners had one thing in common: they warmed the engine first. Cold oil is honey out of the fridge. A small pump pulling honey up a thin hose strains, heats up, and a lot of those one-star reviews end in smoke.

One reviewer timed it on her own boat without meaning to. Four quarts of warm oil: twenty minutes. The next day, one quart of 50-degree oil: fifteen minutes. Her words: "First oil was warm." She gave the pump one star. She'd written the answer into her own review.

The other thing the one-star pile kept tripping over was the switch. Failed, stuck on, and the only way to stop the pump was to rip a clamp off the battery with oil still in the line.

So the OilExtract has a real rocker switch on top, and overcurrent protection that cuts the power if the load spikes, the way it does on cold, thick oil. Neither one makes cold oil thin. Only the five minutes does that. Which is why it's printed here, and again in the guide that comes with the pump.

Start when the line is seated. Stop when the jug is full. No clamp-yanking.

Left: builds a vacuum once and leaks it. Right: pulls the whole time.

Reason 5

About two minutes a quart. The last quart as fast as the first.

Your hand pump isn't slow. It's leaking vacuum.

A hand pump builds its vacuum once, when you pump it, and starts losing it the second you stop. That's why the first quart races up the tube and the last one crawls, and why boat owners describe "one pump then having to wait 30+ seconds." It's a bike tire with a slow leak. You're not tired. Your vacuum is.

A motor doesn't build a vacuum and hope. It pulls the whole time. The OilExtract is rated at 0.13 gallons a minute, which works out to about two minutes a warm quart, so a five-quart engine is roughly ten minutes from switch-on to jug. Warm oil. Cold oil, go get a coffee.

The label rates it for 30 minutes of running at a time. An oil change doesn't come close.

"as bad as watching paint dry"

GreenHulk forum, Sea-Doo owner, on a hand pump

"Gravity took more than 2 hours per warm quart."

Amazon reviewer, on siphoning before switching to a 12V pump

Reason 6

It works where a jack can't.

A parking space. A slope. A jet ski.

There's no underneath on a jet ski or an inboard. The engine sits sealed in the hull and the oil has to come up the dipstick tube; the manufacturers sell their own extraction kits for exactly that reason. The same tube covers a lawn tractor, a generator, and a truck's transmission: pull four quarts of ATF out the dipstick tube, put four back, drive twenty minutes, repeat.

For the car, it means the ground stops mattering. Gravel, a sloped driveway, an apartment lot with a lease that says no jacks and no draining fluids on community property. Nothing goes up, nothing drains on the pavement, and the old oil goes straight into the jug the new oil came in.

One honest limit: it needs a 12V battery to clip to. The car's own, the ski's own, or a jump pack.

"The lease prohibited it."

Car Talk Community member, on why he stopped doing his own oil after moving to an apartment

There's no underneath on a jet ski. The oil has to come up the tube.

What one oil change costs after the pump: oil, a filter, and about fifteen minutes.

Reason 7

$99.95 once. Or $65 to $125 every time.

Two shop visits and the pump has paid for itself.

A synthetic oil change at a shop runs about $65 to $125 depending on the car and the city. The pump is $99.95, once, and you were already buying the oil and the filter. Two visits in, it's free. Every change after that is oil, a filter, and about fifteen minutes standing up.

And the filter: on a lot of engines it sits on top, so nothing goes under the car at all. If yours is underneath, you'll still reach up for it, arm's length, car on its own four wheels. The drain plug still never moves, and the drain plug is the part that cost the man in Reason 2 his $902.

"Why spend $50-$75+ for a tool that really isn't needed?" That's a real forum post, and it's fair. If you like being under the car, keep your ramps. This is for the day you'd rather not be.

Before you order.

Does it really get the oil out through the dipstick tube?

The tube runs to the lowest part of the pan, and on a lot of engines it ends lower than the drain plug. Warm the engine first, feed the line until it stops, and measure what comes out against what your manual says goes in. If your engine has no dipstick tube (some newer BMWs, for example), this isn't the tool for it.

What about the oil filter?

On many engines it sits on top and nothing goes under the car. If yours is underneath, you reach up for it at arm's length with the car on its own wheels. The drain plug still never moves.

Will it burn out like the cheap ones?

No pump likes cold, thick oil. That's why the five-minute warm-up is the first step in the guide. The OilExtract has a real rocker switch so you never stop it by yanking a clamp, and overcurrent protection that cuts the power if the load spikes. Keep each run under 30 minutes, which an oil change never reaches.

How long does it take?

Rated at 0.13 gallons a minute: about two minutes a warm quart, so roughly ten minutes for five quarts. Cold oil is slower in every pump ever made.

What fluids can I use it for?

Engine oil and automatic transmission fluid. Never gasoline, never water, never solvents.

What do I do with the old oil?

Pour it back into the empty jugs the new oil came in. Auto parts stores take used oil.

What do I need that isn't in the box?

A 12V battery to clip to (the vehicle's own, or a jump pack), an empty jug, and your oil and filter. Both lines, both sets of clamps and the guide are in the box.

The jack was never part of the oil change.
The plug was never the only way out.

Warm it five minutes. Line down the tube. Clamps on. Switch. About ten minutes later you're pouring the old oil into the jug the new oil came in, standing up.
