Yea, I was running a W123 on fry oil from a local pizza-n-wings joint in New Jersey about a decade ago... before I knew what havoc it causes to a poorly maintained car. The car came to me with a hand-crank pump in the trunk that took three screw on filters...
Made a mistake one day and filled up behind a Red Lobster... smelled like fish sticks and clams for a month...
I think I'm over the WVO craze... but I did just spot
this W115 300D. Got to wonder what he's hiding with the antique filter on the photos though...
