Oil Extractor Pumps - Asking for Trouble??

They work good on boats. I don't really see how they could hurt.

 

Pretty hard to do it any other way on a boat.

The act of draining the hot oil out the bottom is more likely to carry debris and contaminants out that might be elusive to the suction tube.

I frequently install magnetic drainplugs to collect metal particles (many engines already have them). These should be removed and cleaned.

 

Removed, examined and cleaned.

Yep, yep.
Can head off serious damage sometimes.

 

What model car are you talking about? A 308 you will get most of the oil out but in a 360 that method will get about 3 or 4 quarts.

Do you really have something against doing things the right way?

And last I saw Mercedes doesn't change oil. They build cars, their dealers change oil and they do it the old fashioned way. They lift the car and pull the drain plugs. Thats why Mercedes went to the expense of putting them on the car.

 

Good point, IMO these "upscale outfitters' like Groits have hit their demographic on the head...good for them.

 

I've actually used this for a few years now, and it works pretty well on most cars. I got "suckered" into getting one after seeing the ad in the Griot's catalogue, with a guy changing oil in light colored pants and dress shoes! So it can't be that messy... yeah right. It does help, but...

IMO, it would work well if you follow certain precautions, especially the first time you are using it on a car. I would note the max oil capacity of the engine, and make sure you drain that much oil or very close to it. Then, for the first time you use this method, I would still take off the drain plug to make sure all of the oil is removed. I've done this on several of my cars, and everytime I would take off the drain plug, there would be absolutely no oil dripping out. So subsequent oil changes on that car should be pretty straightforward as long as you drain out the same amount of oil everytime.

No mess so far. Now, depending on where your oil filter is located, you should still be prepared for a few drips of oil. And you may still have to take out a wheel, or crawl underneath the car or put it on a lift. I seriously doubt that guy in the ad was planning on replacing the oil filter in his car.

So it can be a time- and mess-saver/reducer for most cars. Another thing I would consider, too. A lot of the newer cars these days have extended oil change intervals. My M-B has a 10K oil change interval, my daughter's Honda has a 15K interval, and my MDX goes purely by computer and I have no idea how many miles we drive before it tells us it needs an oil change. But as a rule I like changing my oil at 3K mile interval regardless. So for these cars, I would not hesitate to use this pump and get an oil change nice and quick on these cars, for me it is a plus they are getting a few extra oil changes and not worry about getting all of the used oil out (though I still try). But that's just me.

Now for the mandatory Ferrari content ;-) For several years now I have been changing my own oil on my 355. And it has always been a very messy ordeal, no matter what I do. I remember changing the oil the very first time on that car, I got oil not only all over the garage floor, but also on myself. And we are talking my hair, face, shirt, etc. :-( My wife remembers that very well. Anyway, I have since honed my technique, and the very last oil change was a dream, without a drop spilt! And this pump has played a vital role in it, too.

What I did was that I would still put the car on a lift (yeah, I bought a lift just for this purpose after the first oil change), and take out the engine oil plug and drain the oil from the engine the normal way. Then, before removing that oil plug in the oil tank, I would use that pump to suck out as much oil I can out from the top filler hole (of the oil tank, not the engine). After doing so, I would raise the car back up again, and very carefully undo the oil tank drain plug. With rags protecting the frame, I would stop undoing the plug as soon as it drips, then carefully undoing it some more until I get a decent flow. Depending on the rate of the draining oil, it won't take that much time to drain the remaining oil. You can totally remove the plug at this point and you will only get not even a pint of remaining oil (vs. 8 quarts or whatever that tank can hold). Easily controlled and with a very minimum of mess.

So I would say for most cars, and with some care, it definitely helps. Especially the newer, more common cars with the extended oil change intervals, I would not hesitate to use it. However, on our Ferraris with dry sumps, I would not rely on it. You cannot get all of the oil out no matter how hard you try. But, in my experience, I have found it to be of big help, though.

Well, I hope this helps. And of course, this is JMO, and YMMV.

Cheers.

 

Does it suck the filter out the top too?

 

In my opinion, success with an extractor pump probably depends on the engine design. The dipstick doesn't need to measure to the bottom of the pan (if it's that low, it's too late), or especially to the lowest point in the pan. It only needs to measure the top one quart level. In some engines, the extractor tube may not go all the way to the bottom of the pan before hitting an obstruction. Example: On my 365 GT 2+2, the extractor tube bottomed beautifully and worked fine. When it would no longer suck, I measured what was removed and found it two liters short. The last 2 liters of oil (and the dirtiest) had to be removed by way of the drain plug. Since then, the extractor pump is on the shelf gathering dust. I wasted my time and money on it.

To quote Damon Runyon (and later Ronald Reagan), "Trust but verify".

Good luck.

An oil change is one of the easiest jobs there is on a car. That's why places like Jiffy Lube hire unskilled people, pay them minimum wage, and have them stand in a pit and drain oil all day. The whole job is unscrew a bolt, let the oil drain, reinstall bolt, put in oil. Why complicate the job with an extractor pump? Oh yeah, and change the filter. But the pump won't help with that anyway.

Plus, as mentioned, I like to see what's sitting in the bottom of my sump. Drain plug out, see what comes out with the oil, and hope that there are no unexpected chunks of anything.

 

I use an extractor pump for the oil tank on my drysump 308 GTB each second oil change. Reason; emptying the tank via the plug is an incredible mess, because it's situated right above the left rear wheel suspension. ( BTW; any drysump 308 owners here ? How do you perform this ? )
The filler neck on the tank is so wide, that I can examine the bottom of the tank easily with a small lamp.
For the engine sump there is no other possibility than removal of the plug, because these cars have no dipstick for the oil sump.

Have any one try DIY using Oil Extractor Pumps to Oil Change a Ferrari with Dry Sump Lubrication system

Dry Sump i was told some or most Ferrari have this Two Oil Tanks in the Car

 

What I said directly above 11 years ago

Hi Martin Ferrari with the Dry Sump and when i try DIY using Oil Extractor Pumps to Oil Change a Ferrari

i suck out around 5 liter of Black Used Oil and

next step i start the engine and let it run for 10 to 15 mins and hoping the New oil will circulate to next second oil tank and the used oil will circulate to the first oil tank

and i stop the engine and i suck out another 5 liter of Used Black Oil

and after that i start the engine let it run for few mins

and i check the oil stick the oil all look new

is this correct .....?

i DIY oil change using Oil Extractor Pumps

any advice .....?

 

Sorry, but no. What car is this?

As Martin said, no. Never a good idea to start the motor after draining oil (some or all) if you are not certain oil will be supplied to the motor!

 

Could damage the bearings. Why would you do it this way???

I'm out of this discussion since I'm not familiar with these modern V-12 engines. On my old V8 it's easy peasy.
Look for a workshop manual how to perform an oil change. I seriously think, that it's possible, that it's simply not possible to do an oil change with an extractor pump on those modern complicated engines.

The oil change procedure for most vehicles is to drain the oil out of the motor after it has been warmed up as this ensured it is nice and fluid and carries out sediment in the sump/low points depending on where the drain is. This minimises the amount of old oil that can contaminate the new oil. Importantly it also allows you to inspect the drain plug and the old oil for contamination such as metal, water, or other nasty stuff.

The procedure you wrote above doesn’t mention ensuring the correct oil level prior to starting every single time etc, and could result in running the motor without oil supply if you are not sure there is enough oil in the system. Also you are mixing the old oil with the new oil.

Best to read the procedure specific to the 612, you may be able to pump the dry sump tank out to save some mess, but you want to drain as much of the old oil out so that when you refill, you don’t overfill the system as that can also be bad.

 

Also forgot to add, don’t be scared to have a go, just follow the proper factory steps (it should match their intent) and make sure it makes sense

 

You got a good point Mar

 

There is a thread here by Aeroengineman. He attempted oil extraction on his 458 (I witnessed it) and he tried this way and that moving the extractor hose around but left a significant amount of oil behind. Find the thread for details, but it proved in my book, that is simply won't work on some cars. It might work on specific engines...but you would need to test and verify. (measure what you get out)
