Switched to synthetic at 1600 miles.
I was going to do it at the dealers to use the free oil change coupons, but the lines there are out of this world.
Even when I made an appointment, when I came in, the wait was 3 hr. Ridiculous. I will never go back.
I changed at a local shop. I got filters and other stuff from here (http://www.buyourmazdaparts.com/). Got some useful bumperguards from them as well.
Oil is cheap at Walmart.
I would change myself but rather have a receipt in case of warranty issues, plus its a mess.
BTW, the local (reputable) service place could not find the relevant info for the 2010 MS3 in any of the databases so I had to tell them the volume to use and the filter type (which is different than previous MS3s).
just did mine yesterday i have 950 miles on the car still
changed to mobil1 10/30 synthetic oil and filter also oem filter and for the change so fast i like to know what i have in the car just to be sure and mor confy thats for me..
Because factory oil is dino 5w-20 and is more prone to have metal shavings from breaking in the engine, as well as fuel dilution in the oil itself since this car runs pig rich.
