The irony is that not even the dealers will use a torque wrench for an oil change. I've worked in a few shops before (small and dealers), what do you use that wrench on during an oil change? I've never seen anyone use one for a job like that! Though I'm impressed with the level of your documentation detail for warranty disputes.I figure I'm around 45 minutes. Normally I can do it in around 20-30, but I take a lot of documentation for the warranty. I video tape my oil changes with my phone as well, so it takes longer to explain everything, torque setting on the torque wrench, etc. I want to make it as difficult as possible for the dealer to deny warranty service.
I also tend to do some quick visual checks as well (such as coolant level, lube my door hinges, etc). It all adds up.
thx for the tip!Never timed it. I take my time. Takes a tad longer to suck it out, but it avoids contact with very hot oil.
Use a zip lock bag over the oil filter and avoid getting any oil on the floor down there.
Could be quicker if Mazda did the right thing and made the filter removable from above like most European and some American vehicles.
