Using oil extractor on V6, how much left in pan, filter?

On the gen-3 V6 engine, has anyone used an engine oil extractor through the dipstick tube for your oil changes, and after extracting, pulled the oil pan drain plug to see how much, if any, oil is left via a gravity drain of the pan?

It varies from vehicle to vehicle since some cars are designed to use an extractor and little or nothing is left if you then do a gravity drain of the oil pan. I just wondered how much is left in the case of a tacoma.

Separately from that, the oil filter seems to have its own "reservoir" that will not drain via the drain plug. From the videos I've seen, it looks like somewhere around 4-8 ounces of additional oil comes out when you pull/drain the filter cartridge assembly. Does that sound about right, or do you think it's more than that?

(I ask because I put very low miles on my Tacoma and think I might alternate between extracting via dipstick tube only (not changing the filter, not pulling the drain plug) on one oil change, then full drain and filter replacement on the next. So I wanted to guesstimate how much new oil I'd need for the extractor-only version of an oil change when the filter is not changed and the drain plug is not pulled.

 

But why? Sounds like a lot of hassle, and potential risk of filter getting dirty and going into bypass to save $10?

I have one of those extractors, I use it on my boat. If I could change oil the normal way on my boat I would. The extractor is a hassle.

 

I guess I'm a little confused? Just do full oil changes at the regular mileage interval and be done with it. If you put low miles on the truck then it just means longer time goes by between them rather than doubling the time and money spent for no reason.

 

If u want an exact you amount, u could always measure the amount you pulled out? Or measure via the dipstick...

 

It's how the cool kids with slammed cars do it, because they can't get a jack under their car.

 

Last time I did an oil change, I first did oil extraction, then opened drain on a fumito drain valve I have in the pan. Only got maybe part of a teaspoon out of the fumito valve, (probably just the volume on top of the ball valve).

I did not check how much the fumito valve is holding, so it may hold a bit more than the normal drain plug so my test does not prove anything definitively. However, based on my single test point, I feel comfortable doing extraction instead of drain plug on the 3rd gen.

I did normal oil filter drain while vacuuming, seemed like alot of oil in there, I can believe 4-8 ounces, but did no measurements. (made a big mess with that, not used to the cartridges like I am doing oil on 1930's airplane engine).


Note, I feel comfortable with the oil extractor, but I would just do the cartridge also if I were you. (at least until the motor is getting clapped out)

 

I understand how it works and have done it before, it just sounds like the OP wants to do double the number of oil changes just because he doesn't drive the truck much.

 

Or he's just trying to be cool? Maybe he doesn't like getting on his back?

Tis a turd gen tred afterall

 

Thanks for actually answering my question.

The recommended interval is 10k miles, which could take multiple years to reach. There just isn't good data on time-based not mileage-based oil change intervals (for any vehicle, not just tacoma), and whether there is any risk in long intervals between oil changes even if low operating hours/miles on the engine. So I figure annual changes of the oil as a default, regardless of miles, would be a quick, cheap, reasonable plan. But the filter isn't going to have filtered much after low miles, so I figured, why change that every time.

 

At low mileage I would use gas extender and even with extender not keep the same gas in the tank more than a year.

 

Toyota actual makes it clear that its 5k miles or 6 months (for the pointless interval), which ever first, and 10k miles or 12 months (for the actual oil change, etc).

12 months maximum is definitely the normal. Is it conservative?, I dont know but it is basically universal.

i am an old fart,75, and change my oil myself and for me it is a real pain in the ass. yes, getting on my back , removing the metal cover, etc. i know you young guys can do it in 15 minutes but for me is more like 45 minutes, you will see what i mean when you get to 75.

 

What type of driving do you do primarily? If it's short trips (<20 miles), then you should be doing more frequent changes, irrespective of your annual total, and I would suggest that changing the oil in the engine without changing the filter element is really a waste of money and oil.

 

Interesting, since the advent of 0W-20 (and my normal technique of doing changes when oil is warm), I use the extractor alot more...
I dont even bother having to wipe out my oil change pan any more...

 

Don't get me wrong, it's not like the extractor is terrible to use. I use one of the can style oil change pans, which, when I am done I just put the lid on and take to the recycling place. The difference really is a personal preference, for me, I prefer directly into the oil pan.

 

I get you.
with 0w-20 it seems to splash so bad out of several of my vehicles, that I find it really irritating (compared to good old 5w-30, 20w-50, etc even at full temperature).
Especially ones with the drain plug coming out at 45 degrees...

 

I know it scares people, but using an oil extractor makes oil changes a lot easier. Audi actually sets their cars up to do oil changes via extractors and I believe the dealerships use extractors to do factory oil changes. You don't need to crawl under the car and pull the drain plug, replace crush washers, wait for the oil to cool down, etc..
I haven't seen any data that shows extractors leave enough oil behind that could potentially cause damage, if done correctly.

 

So true, The first time I did an oil change on my taco, I was worried they just put colored water in .

 

In Germany at some of the gas stations they have oil extraction pumps next to the building. It's a coin op machine and you pull the dipstick, vacuum out your oil, refill and go on your way.

 

All but the base model Audis don't even have dipticks anymore. They still have the area where the dipstick would normally go, which allows easy access to put the extractor tubing in.
