Just went out to start an oil change and the entire underneath of the engine compartment is sealed off with a huge plastic shell. There is NOTHING accessible. This thing is riveted to the frame.


How are you guys doing your oil change? I have no access from the bottom! No oil drain plugs etc!!!!

WTF?

It's just held on by 6 10mm bolts and 1 screw.

Now struggling with the filter... urrrggggghhhh....

There's several threads about this, just search for them. And you need a special tool for the filter.

Never saw anyone mention the underbody shield!

Got it all changed out. One more tip: The filter wrench is known in the industry as a type "B" filter wrench (aka 76mm/14 flutes).

Used a Napa gold filter and she's up and running.

Not sure if anyone mentioned this before, but the Mazda dealer told me he could sell me the parts to convert the speed to a spin-on filter and it wouldn't void any warranties.

I just went to the dealer this weekend and bought some filters and the wrench. Filters with o-rings was 6.00 and the wrench was 17.00. Going to change the oil in a couple weeks.

I changed the oil this weekend (first time). It was cake! The filter wrench can be picked up from Wal-Mart/autozone/Advance Auto, etc much cheaper then the dealer.

Just changed my oil last night and would like to add a little to the discussion. There are 8 bolts and 1 plastic pop-rivet that hold on the plastic belly pan. The oil filter drain plug requires a 6mm hex key/allenwrench to remove. It's not really necessary to drain since it doesn't hold alot of oil, and can be easily dumped once the cap is removed. I bought a filter wrench at Advanced Auto for $6 and worked like a charm. Just remember to put a little oil on the new o-ring like you would a spin-on. Most importantly, I have never seen oil shoot so far out of the oil pan drain like this one. It completely cleared my drain pan as it came out a good 10" horizontally. Also, remember to put the drain plug washer back on, my others cars didn't have this so I almost forgot.
