oil change

I have to change the oil on my 1995 E 320 for the first time. I bought a filter-element, but can not find where to put it. And also,....... where is the oil drain plug

The oil filter canister is along the firewall (top of engine, not bottom). To get to the drain plug you first need to remove the protective cover (bolts along the front and back). The drain is on the left (when facing the car).

Thanks, Josh. I will check it out. The drrain is on the right (facing the car) in the oilpan.

To make your life much easier, I'd suggest purchasing a LiquiVac or other similar oil suction devices (Griot's Garage sells another variety). It consists of a canister with a suction pump and a plastic tube which goes down the oil dip stick.

I can change the oil and filter on my 95 E320 in 20 minutes, less time than it takes to drive the car to the dealer. Draining the oil from the bottom is the hard way. Do it like the dealers do......suction it through the dipstick tube.

That is quite correct.

Actually the pipe of the dip stick is long enough rirht to the bottom of the pan and it does not need an extra tube in it.

A rubber host pushed tightly to the upper end of the pipe does the same and the hose may be much bigger than pte plastic tube used in the pipe.

You do not need to get under the car at all. Everything can be done above the engine.

Not a good idea. The primary thing you want get out of the system is any crud or bits that are sitting at the bottom.

Suction is less likely to get this.

Draining through the drain plug with the engine HOT is the best way.

Also, I don't know any high quality shop that uses suction to change oil.

You don't qualify DB dealer as a high qualify shop?

Suction takes it all out. You can test this by using suction first and taking the plug off then. I have done this with my previous Benz (190E

2,6) some 15 years ago. Nothing more come out. I have never touched the plug ever since.

Duh! You already drained all the oil, which would have flushed the crud out!

More power to you. I prefer the old school way.

And you suppose the oil flowing out thru the dip stick pipe don't flush the crud out, or what?

The Benz dip stick pipe is designed to this purpose. It is long enough to the bottom of the oil pan.

Well, that's of cource allowed to you. I do not do it that way any more.

No it doesn't because it's working AGAINST gravity.

Impossible. There has to to be some space for it to gain suction.

Thanks, and you are certainly allowed to use the suction method :~)

Ultimately, timely and regular changing of the oil via either method is the most important thing.

Actually 'my' method seems to be approved by Benz but as you did say most important is to change in. Not the method.

This is actually incorrect. If you look at the oil pan in cross section, there is a lip at the point of the gravity drain plug. This leaves a slight amount of oil in the bottom of the pan. The suction method removes MORE oil than by gravity. Most MB dealerships use the suction method and it's approved by Daimler Benz.

That's what I tryed to tell too but I was not straight enough with the words.

If suction is made using the dip stick tube without any tiny plastic tube in it and the oil is warm, it takes 1-2 minutes and all oil is out.

The product sold by this company(TT 28), replaces the good old DRAIN PLUG with a plug featuring a snap on pressure fitting on it, and the oil is drained from there, not via the dipstick tube. This actually provides the best of both worlds (ie suction and gravity).

The MB approved machine doesn't have pictures of how it works, so I can't say whether that actually uses the dipstick tube...

Well, that might be the case here. I did not find anything better from the internet with a quite hasty seek.

Certainly the drain plug which has a special fitting for vacuum oil changing seems to satisfy my protests, and is very slick. I wonder how much this machine costs?

I am going to find out. Certainly the idea of never needing to pull the drain plug or deal with draining the oil into a pan and pouring it into a bottle etc. is very appealing.

This must be a HUGE savings for big fleets with high duty cycles.

Hey Martin,

Check with Boater's World (Southcenter Westfield). They carry a small self-priming dipstick pump which attaches to a cordless drill. Simply slide the thin tube into the dipstick sheath until it hits the crankcase. The other side of the small pump is a garden hose size tube, which can go into a

2.5 or 5 gal gasoline canister to collect the engine oil. Takes about 2 minutes to pump the oil out.

I've been using the dipstick oil change method for five years on all my cars. I first used a hand pump (also from a marine store), then got a TopSider floor model (built in hand pump fitted to the top neck of a 5 gal. metal floor canister). The manual pumps are good, but they get to be very tiring on the hand due to the heavy suction of the thin tube extracting the oil. For peace of mind, you can check out the oil drain plug to see how well the bottom sludge removed after the first couple of dipstick oil changes. But as I drive the car 30 minutes immediately before an oil change, I've not seen any sludge drip down that the dipstick tube failed to get. At least, nothing that would have drained out the bottom using a pan under the car in the first place.

Another plus to a dipstick oil change is that your oil pan drainplug stays untouched. For some reason, I always feel I have to check and recheck and check again to make sure the drainplug was seated tight and didn't start dripping oil after the washer was replaced.

What's the difference you see in using dipstick pipe to empty the pan compared to connecting an other pipe to the draining plug and using it?
