I recently bought my 2010 Corolla 1.8 from a family member who was going out of country to work for 2 years and no longer needed the car.  They bought it brand new in Feb 2010 and it has had all of its oil changes from Toyota dealerships since new.It was time for an oil change last monnth, and I put the car on the small midrise sissor lift I have in my home shop. I attached the Assenmacher tool to a 1/2 drive ratchet with the correct socket and attempted to remove the filter housing.  It would not budge.  I decided to wait a while to let the housing area cool off since the housing is made of plastic and threads into metal, resulting in a mismatch of thermal expansion characterics (bad design IMHO).  I tried again after 3 hours, it still would not loosen.  I then got a 2.5 foot breaker bar and tried again; it would not loosen.About this time, I got a litte worried and decided to check the net for problems with removing this filter housing. I read one report where the housing was so tight, they had to cut the housing off and buy a new one. I finally decided to use my 1/2" air impact and attempt to remove it. I was initally concerned that the impact would break the stub end off the Assenmacher tool, but I had nothing to loose by trying.  I began using the impact and after 5 seconds of use, I noticed the plastic housing finally starting to loosen. A couple more seconds and it came off.I inspected the threaded area of the housing closely to see if it has somehow been cross threaded during installation at the toyota dealership; no problems found. I guess some oil lube flunky at the dealership has installed it with an air impact gun. I completed the oil drain and reinstalled the filter and new O ring and torqued to required specification of 18 foot lbs.Praise the Assenmacher tool, it withstood the hammering of my air impact and allowed me to remove this greatly overtightend filter housing on my 2010 Corolla 1.8.THIS TOOL IS WORTH ITS WEIGHT IN GOLD.  BUY NO OTHER.One final comment: Just because someone takes their car to dealerships does not need a job as simple as an oil change will be done correctly.  Do your own work and ensure it is done properly is you have the necessary tools and skills.
