Engine oil extraction on BRZ

Hello all,


Couldnt find much info on the specific problem i'm facing,
really appreciate any valuable inputs.

I have done 2x Engine oil change myself using the extraction method.
(i do not have equipment/space for the drain plug method)

I am using a Hand Pump with 1/4" (OD) tubing thru the Dipstick opening.

Both times, i face difficulties sucking out all (or most) of the oil.
I may suck out the first 1L easily, then have to twist & turn the tubing, and also pull out & re-insert the tubing for another 1L and so on,
it can go as deep as 1.2m from the Dipstick opening tip.
(i tied a cable tie at the 1.5m mark of the 2m tubing)


I tried reading other drivers experience,
Looks like few people actually face this issue (or they didnt share it).

I'm using quality PU tubing (use in Semiconductor pneumatic line),
Have Oil fill cap removed prior extracting.
My first time, i warm up the oil temp till its 50deg Celsius,
while the 2nd time, i didnt warm-up the engine,
but both times i face similar issues.
With 2 persons, 1 pax pumping the lever & the other pax twisting/pushing/pulling the tube, it takes about 2Hr to extract 4.7L (both time).
I suspect another 0.1L inside the pump.
Before i start, the Oil level is around Max in the morning when engine is cold, from my experience, its around 5L Ī 0.1L.

I'm happy with 4.7L, just hope i can do it much faster.

Is it because the dipstick need to go thru many section of the boxer engine to reach the oil sump ?
Compared to other non-boxer engine that have more "direct" route ?


Is it possible to insert the tubing thru the center hole after you remove the Oil Filter ?
(not sure if there is anything like waterpump in between)

I tried looking at quite a few FA20 engine overhaul,
but just couldnt figure out where the dipstick "route" to the oil sump is.


Many Thanks.

Unless you made a typo, you still have ~0.8 L used oil in the engine. The capacity is 5.48 L

Why not just get a fumoto valve with the nipple so you can attach your hose and drain from the bottom?

Hello Guys,


The last 0.5L of the used oil doesnt bother me.
I'll probably clock less than 8k km a year since i not working now and i change it at least once a year.

Regarding the Oil Capacity, i believe there is some ambiguity on the Manuals.

If you follow the Owner Manual (both Toy/Subi), it state:
"to wait five minutes or more for the oil to return to the oil pan before checking the oil level."
If you top-up to Full on hot engine,
That means by the next morning, the dipstick will be around 120-130%.
(after dealer servicing, i always get this reading on the next morning)

I suppose this scenario will account for the 5.4L in the Spec.


But if you follow the BRZ Shop Service Manual (which i do), it states:

"To prevent overfilling of engine oil, do not add oil above “F” mark when the engine is cold."
In this case, i believe you will only have ~5.0-5.2L in your engine.


For the Fumoto valve,
can your arm reach it without jacking up ?
My head cannot clear the chassis.




Best Rgds

You cannot. I did not know your goal was to change oil without lifting the car.

I have always used a Pneumatic/Manual Fluid Extractor to change my oil. What l do is remove the dip stick tube so I can use a larger diameter tube when sucking out the oil. Doing it this way was faster than draining with far less mess. All it takes is to remove the 10mm bolt at the top of the tube and then pull it out (friction fit). After doing this for years all I had to do is refresh the o ring on the bottom end of the tube as a precaution. With the volume markings on the side of the extractor I’m satisfied that I’m get the same volume as if I had used the drain plug. All so I should mention that the tubes that came with the extractor are made from a very stiff material and can be easily push deep into the oil pan.

I'll give it a try next oil change and see how it does. I am a distributor for a couple different brands of these though I have never really been that impressed with them.

Do you need to cut the tube at an angle to suck the bottom of the pan?

Any other trucks for this? What pump do you use?

Iíve always thought this may be a nicer way to change oil, but Iíve never taken the plunge past a fumoto valve.

Just used the tube as supplied with the pump. I bought a Fumoto valve but never bothered installing it because this was so much more convenient. Ended up installing it on the wifeís vehicle instead.

I have two pneumatic extractors in the shop now that production uses from Liquid Dynamics. I have just never considered using them on my car. I have used them on my motorcycle since you have to drop the exhaust to get to the drain plug. I also distribute for John Dow Industries who makes a pneumatic, and I have an electric one we sell, but it is not very good.

for both transmission and engine pan is a bit lower than the plug. So you should get more out doing topside vacuum extraction.

many have had great experiences using the marine extractor

I think the extractor I have have was rebranded to powerfist which is the brand name for Princess Auto products. While the one I got years ago was a 9.5 litre size this 6 litre one they have on their web site looks just like mine, just shorter.
