Blah. I change my own oil. Not only is it a learning experience, it gives you a more "one on one" feeling with your car. If you don't care about the MSP, go take it to Jiffy Lube and get the $3.99 special or something. However, this is the perfect car to get your hands dirty with.
The only hard thing is getting the filter off the first time. As someone previously stated, Mazda must have had a gorilla working the line when they installed the oil filters. Not only is it tight, but it's not a standard size.
Some tips for oil stuff:
1) When taking the filter off, use a oil filter wrench. If the wrench is too big, which most are, wrap a non-sliding material around the oil filter. Hell, even a towel works with enough pressure on it. That way you "increase" the size of the filter and hopefully your wrench can get it.
2) If you still can't get it off with a wrench, go get one of those rubber non-slip pads used to open bottles/change lightbulbs. A lot of companies give them away as promotional items. That way you can get your hand up in there and grip it without your hand sliding everywhere.
3) As far as oil goes... I'll go back to the statement above.. If you don't care about the MSP, put whatever you want in it. However, if you care enough about it, don't skimp out on what may be the most important part of the engine. I, and I'm one of the minority here for some reason, use Royal Purple Racing 21. Others preach about Mobil 1 and insist that's all you should use. I really don't know why. Maybe because it's a big brand name and it's been around longer than these "next generation" ones; I don't know. All I do know is that with RP oil, even those people that don't care about the car and don't keep up with what I do notice there's a difference. I don't have a dyno to prove it, but it's definately noticable. This is the first car I've used Royal Purple in and I'm using it for life. Price is around the same as other synthetics (~$8-9USD) but from a person that used to use Redline and *sometimes* Mobil 1, there's a HUGE difference.
Plus, RP oil is literally purple. Cool stuff.
