Thanks Max
The main problem was Hyundai, in their infinite wisdom) put a chassis rail on one side of the plug, and the exhaust on the other. Means I couldn't get a longer bar on without it hitting the ground.
The solution ended up being a Victa lower handle - the lower section that mounts to the deck. The bend in it allowed enough space off the ground, and enough leverage (just).
The sump plug was buggered (half rounded), so I went to SCA and got a new one. Came home, fitted well.
Then I went to remove the filter. Turns out the filter strap wrench that does z154 ( commodore& camira), and z9 (Kingswood) filters was too big and wouldn't fit the smaller z79a I had to remove.
Back to SCA for a smaller strap wrench, and the filter wouldn't come off either.
Just about tore it in half getting it off.
All done now, but am going to ring that bloody mechanic tomorrow.
4 hours to change the bloody oil - started at 4, ended at 8.
Thanks
