So if Godzilla is pumping the crap out of the bloody thing, it's going to blow something! I've had mine for over a decade and it has seen synthetic of just about every brand and dino too. Still works like the day I bought it. Dollars to donuts that Mr. Bimmer did a Godzilla number on his extractor.

Here is who makes mine (Griot's typically re-boxes most of its items under the Griot's label): Pela Oil Extractor - Large PL650

How To Use: PL-650 Big PELA & PELA Pro 14 Oil Extractors*

*On mine, Griot's put a five pump warning (most likely to keep Godzilla from blowing seals).
