[AT] Canola to diesel

[George Willer]

I don't think any basic changes can be retroactive.  It's been about 17
years since I drove any Mercedes regularly.  As far as I know the 190,
190DC, 200D, 220D, 240D, and 300D remain pre-chamber engines.  As best I can
tell they are NOT true diesels.  The only Mercedes I currently own is a 450
SLC and it's too valuable to drive.
