If this were true, it wouldn't be available to use in any remotely modern engine, gas or diesel.

Agreed...if you're burning that much oil to begin with, you'd have bigger concerns than just the life expectancy of your cats.

So I did my first oil change yesterday with Castrol 0w40. Iíve changed a lot of oil in a lot of different cars over the years and Iíve got to say this one is possibly the worst set up Iíve personally experienced. First the oil launches itself from the drain plug on a parabolic trajectory about 2.5 feet towards the passenger side of the car. Next when you take off the filter cap it spills dirty oil all down the side of the housing and the alternator. Finally...you have to either ruin a shop towel soaking up old oil in the housing...or use half a roll of paper towels and risk leaving some paper behind in the system.

I just asked my self so many times yesterday...WTH were the bmw engineers thinking???

On another note...I was shocked at how dirty the oil was. Car has 91k miles...last changed at 86k...is this normal???

Really? I've changed the oil/filter several times and it's a fairly clean process. Much better than my kids 07 Rabbit or my '12 F150 which drips from the front for days afterwards.

For the VW you probably doing it incorrectly. I have owned 5 VW and never had an issue. Isn't messy at since you are able to drain the oil filter cap first.

Yup. Do that. Another marvel of VW engineering.
