Need help with Mighty vac extractor
The oil does act thick and it takes a lot of vacuum to pull it up the tube. Diesel engines also make black paint in their oil pan and I'm very careful not to spill that nasty old oil on anything.
But as far as difficult to push the tube down, I've never had a problem. Maybe yours is configured differently than mine and there is a kink in the tube.
Good luck,
Peter
