Hello,

I did a search but maybe I just can't find it. Is there a how to for changing the oil in a Speed6? Is it the same as the change oil for the 3.0 V6 on mazdatech? Thanks for any assistance!

It will probably be more like an oil change for the 6i since the Speed6 is a 2.3L 4-Cyl. also. I'm not sure of what changes there are for the Speed6, but I think it has a larger oil pan or possibly oil pump. Actually there is some good info over on 6Tech. Looks like the same (6i) cartridge filter, but an oil cooler adaptor is added in along with some other goodies to improve lubrication and cooling... http://forum.mazda6tech.com/about4207.html

It's a cartridge filter like the 6i. You need to remove the lower engine cover ( 6 bolts I think). Remove the drain plug. Remove the cartridge. Replace the cartridge and special gaskets. I think there is a special tool to remove the cartridge retainer so as to avoid damaging it.

Basically it's a PITA. If not for the oil cooler, you could put the spin-on filter conversion on it.

I paid $80 to have a shop do the oil change w/ Mobil 1. I'm sure they used their shitty filter and did not use any special tools and did not replace the gaskets. Needless to say, I'm looking for a better solution.

Best bet is have the dealer do it or do it yourself with genuine Mazda filter and gaskets to have it done right.

What happens if you don't change the O-rings? The new filter I bought had a slightly damaged outer O-ring, so I reused the old one.

They can swell, start to leak, and possibly cause engine failure to lack of lubrication.

The oil pressure for a L3 engine is pretty high...anything anywhere that leaks is horribly bad.

Oil pressure for an L3 w/TC is 43-79.9 PSI at 3000 rpm's. You can lose alot of oil REALLY fast if you get a leak.

And guess what happens if it was caused by you improperly changing the filter...thats right, not covered under warranty :(.

To Put it even simpler....Just pay the $30.00 to let the dealership do it.

You brought the Speed, you can atleast afford $30.00 every 5000 miles
