yeah - i tip the car slightly to the right so it puts the drain plug low and pretty much all drains out, and let it go until it stops.

Paul, tell us more about how you actually use the vacuum pump on the 968. Is the oil sucked up through a tube you fish down into the sump, or?? I agree with Flash, you wouldn't want to do anything that could allow oil to get up into the block without going through the filter.

I haven't done it on the 968 yet.....but you just feed the tube down the dipstick with the dipstick removed. You pump the device and create a vacuum, and it sucks the oil out. Most dealers do oil changes this way now, Mercedes has been doing it this way for years. I bought it to do the oil changes on my ML350, and now I use it on the S8.....and soon to be on the 968. It works great.





Here is a basic procedure that shows the device and how to use it that I wrote.

hmmm - out the dipstick tube is a valid concept, but i think you may be hard pressed to get a hose down there. our tube is very skinny. also, i believe there is a turn you will have to make at the bottom, in order to reach the bottom of the pan, or even to get past the bottom of the dipstick hole.

I've never found changing the oil to be that messy. I've had worse cars for making a mess. I'm certainly not going to pay someone to do it.

I'll let you know how it goes....as I mentioned, you can always take the drain plug out after you take out 90% of the oil....that's the part that I don't like....little clearance under these cars and then 7.5 quarts oozing out all at once. It's just a nice, neat way to do the oil change.

That's exactly what I've done for years on my BMWs.



The MityVac is great --

http://www.amazon.com/Mityvac-7201-Fluid...B0002SR7TC



It comes with different sized plastic hoses - one small enough in diameter to reach the bottom of the dipstick tube.



Suck 90%+ of the oil out that way - quik and clean, and then open the pan plug to let the rest drain out.



BMWs also come from the factory with topside oil filter canisters (at least all the ones I've owned) -- like how the Canton works.

Between that and the mityvac,oil changes are super quik and clean.



I'm all set with the Canton set up for the 968 -- next time I change the oil, it's getting installed.

So looking forward to that

Of Course -- that's as to MY BMWs... the wife's 2010 x5 doesnt have a frickin dipstick...!!!



Older cars are the best

if you're going to open up the drain plug anyway, what's the point? i can see the advantage, assuming you can get all of the oil out, and do it from a place that would not allow particulates to re-enter the engine. it has to stop there though. i fail to understand the advantage if you are going to pull the plug anyway. in fact, it's a whole lot more hassle. you have to hook that thing up, suck it out, empty it, clean it. what a pain in the butt. and you're still going to pull the plug anyway??? so, another drain pan, dumping, bottling, clean up and disposal to deal with??? aren't things complicated enough with this car?

The mityvac is self contained and super easy to use -- no real additional set up or clean up reqd.

Also makes for a super easy & clean transport to the oil recycling drop off.



The advantage I've found with doing this before the plug is as Paul W also mentioned -- a Lot less oil (and velocity) to worry about when you open the plug.

That alone saves me time and mess on the overshoot and splatter down below.

where i am, we have to have the oil in containers that close to drop it off. we don't get to pour it out.



i have yet to have a problem with the drain pan. i just hold it up to the plug, remove the plug, and let it flow, lowering the pan down after the first couple of seconds. clean, simple, fast, and FREE.



i definitely do not want to leave oil in something like that, so it would have to be thoroughly cleaned after each use. i even wipe out my drain pan with brakekleen after each use. in fact, i have 3 different pans, one for each type of liquid. i never mix them.



but, if you are not going to remove the plug, i can see the advantage of sucking it out, assuming it can be done. i only see added work otherwise. it will be interesting to see how much comes out. anything much less than 6 quarts though, and it isn't enough. that leaves too much oil, and the dirtiest oil at that, still in the pan, ready to find its way back up into your engine.



a simple petcock on the drain plug would be a much more viable solution, though it would still require lifting up the car a bit.

Flash, you are correct, I would not get under the car and pull the plug....I just figured I would hold this little secret otherwise you would FLAME me!

lol - no worries. like i said, i can see the advantages if you are either willing to let the sludge stay in the engine, or if it successfully removes it. but the minute you decide to pull the plug anyway, it's all been a huge waste of time and money.



i know people who just change the oil, and not the filter too. cracks me up. if they are going to do it half-assed, they should do it the other way around, and change the filter, but leave the oil.



it's funny how oil is such a hot button for many people. there are those who refuse to change it in less than 15k miles, regardless of all data to indicate how it has broken down and is not protecting the engine the same as if it was clean. there are those who religiously change it at 3k miles, even though today's cars don't need it to be that often, as there is far less fuel in the oil. many swear by one brand, with no data to support the decision. others swear by a brand, because of the marketing, and in spite of data. i've never seen such a diversity of opinion on any other topic, like i have on oil.



interesting stuff.

With the purchase of the MaxJax Lift, I also bought this oil drain for lifts. Raising the 968 on the lift (about 46" - that is the maximum that the MaxJax goes to because it is made for a garage with an 8' ~ 9' ceiling), rolling the drain canister under there while sitting on a rolling work shop seat, has made the oil change a delight to do. Way easier than when I used to try and squeeze under there with the 968 on a pair of ramps.

Hope this post does not sound too cocky for those that do not have a lift, but it is GREAT to have one! <img src="/forum/images/smilies/968/rock.gif" class="smilie" alt="" />

i miss my shop, for reasons like that. i used to have one not all that different.



i may yet install the maxjax. when i first posted about it, maybe 5 years ago, i was on the fence. i still am, and for the same reasons. just not sure i can drill into my tension slab, and not sure i want people to find out i have a lift. i spend too much time working on cars as it is, and it's hard enough to keep the garage clean now.



thankfully, with the canton filter, the mess is gone, and since i don't drive the car that much, the oil changes are not that frequent. so, putting it on stands is not that big of a deal.

I stuck in a petcock as my treat to oil changes. No wrench and no upside down talk to myself about "righty tighty lefty loosy", just move the lever and out she comes. And yes, the lever locks into place so it can't accidentally open up.

as long as it doesn't leak, i see that as the best solution. i'm nuts about leaks though (not even 1 drop allowed, and anybody who has seen my garage would understand why), so i haven't wanted to experiment.



so - does it leak?

Fleetwood, which Canton unit did you get? I am not sure if the 4" or the 6.25" is best for the 968. See my earlier post in this thread for the links to the JEGS website.

the 6.25" won't fit

I have the brass valve (Fumoto, I think) on my Civic and wife's Highlander. The Civic is going on 225k miles now and the valve has never leaked, opened accidentally, or failed to work. Best $25 I ever spent for that car. I'll be installing one in the 968 shortly.
