i just changed my oil via the oilpan.i tried using the topsider but it took 1.5 hrs just to get 3 litres.it seemed like i was getting a air leak at the input tube side.i could play with the inlet tube to alleviate the hissing sound but it didn't seem to help all that much.has anybody had problems with this device and how did you rectify?also anybody have any other ways-either homegrown or manufactured.i ran my engine for 30 minutes prior to changing to warm up the oil
'change it hot and change it often'-right larry??
thanks
