Need I comment? :confused:

[QUOTE=82-300td]I'd like to make an oil seperator but I have not come up with a small/goodlooking design yet (I'm too dang cheap, as you can see, to spent $50+ on an aluminium "cyclone can").[QUOTE]

For a cheap oil seperator I've seen some of the old timers put an inline fuel filter on their road draft tube. All the ones I've ever seen had some oil residue in them and none getting past it. Just a thought. I can relate to your frugality.

What the heck is a "road draft tube"? Does that mean whatever comes out of your breather drips onto the road? Not very responsible... :(

Copied from a dictionary of Automotive term website

road-draft tube:
British term for oil breather pipe or oil breather tube.

oil breather pipe:
A crankcase breather pipe used prior to engine emission control systems to remove fumes and pressure from the engine crankcase. Also called road-draft tube. The tube, which was connected to the crankcase and suspended slightly above the ground, depended on venturi action to create a partial vacuum as the vehicle moved. The method was ineffective below about 20 mph


After thinking about your comment about dripping oil a little on the road I want to stress that the in-line fuel filter I mentioned above takes care of that. Also, if you're worried about dripping oil on the road, You probably want to rethink driving a Benz. :rolleyes2

I don't know about your's but mine marks it's spot like an old hound dog I used to have.

Draft tube would be great on a northeastern car adn it would keep the underside of the car coated in a fresh coat of oil from blowby mist. the 2 days I tried that left my underside glistening with oil.

OK, OK, let the ridicule begin :P

I fitted a similar intake to this a little while ago and just completed my first full tank with it. Over the previous 3,500 miles my mileage varied between 25.7 and 26.5 MPG - my driving is very predictable!

The first tank with the wunder-filter returned 30.5 MPG.

I stopped filling the tank at the point where froth was spilling out the filler having kept the rate of flow quite low during filling to minimise just this effect. It could be that I underfilled, the next tank will tell more.

I usually refuel when the gauge gets to around a quarter tank, which is typically 340 miles or so, this time I was at 403 miles.

Not very scientific, and only one data point, but obviously I am now intrigued!

It doesn't supprise me one bit that your mileage got better. I have the same type of air filter set up on my truck and my mileage is better than most. It's a F350 w/a 7.3L turbo engine. I average 23MPG. Everyone else on another forum I frequent gets anywhere from 15-18. It's good to hear that there is some possitive results w/ this set-up on our MB's.

I bet if we open up the exhaust a little, that the mileage would get a little better when done along w/ an open air filter.
