changed filter and put in oil, turned on motor and oil leaked out of filter, had tightened properly too, what you think?

Wrong filter? The seal from the old filter did not come off with old filter, so maybe there is 2 rubber seals?

got the right filter, and old oil filter had still seal on, so no 2 seals.

Guess you could check the surface of where the filter goes to make sure nothing was on there before you screwed new filter up,

Should work, that filter fits a broad range of 80s and 90s Mazda engines, including those fitted to Ford equivalents. You certain the filter is as tight as you can get it by hand and its not coming from the seam at the base and not the seal?

so tight i cant get it off by hand, need a spanner to get filter off.

I'm also for the old rubber filter ring has attached itself to the block when removing the old filter
Happened to me years ago on a Cortina,always check now

If it's that tight you've probably twisted the rubber ring out of shape. Filter only needs to be hand tightened

I had one that the thread was stuffed and I tightened by feel, you could not see it so it was nip and 1/2 turn more, started car and $80 worth of Motul went on the floor, got a new one but no replacement for oil.

I'd be willing to bet that most of us have done that at one time or another, just the once mind you.

filter so tight it buckled the thread inside the filter and now its out of thread and the filter is not sealing on its rubber no more because you pulled the insieds out of the filter. You never ever tighten a filter with a spanner and always oil the seal 1 hand with all the force your wrist has is the correct torque for oil filters. unless your superman of course only use quality filkters like "wix" or factory car make filters.

On the very rare occasions when I've had a slight leak, I found the solution was simply back it off and reseat the O ring against the mounting face of the block, so you could give that a try, assuming the filter isn't faulty or damaged in some other way, as intrade suggested for example.

Are you sure you haven't cross threaded the filter onto the fitting? Get another filter ( preferably Mazda original) as it's possible the one you have is either defective or damaged? Read the fitting instructions, tighten hand tight about 1/3 to 1/2 turn after seal contacts the base flange + always smear a little oil on seal ring before fitting.

Most fitting instructions I've seen quote 3/4 turn after initial contact.

Which generally equates to as tight as most people can get it with one hand!

I'm for over tightened filter which has put seal out of shape

A bit of oil spread on the rubber o ring before you put it on helps.

OR . a bit of gunk has dropped under the seal AS you fitted the filter
Pull it off/ clean & refit (even if it looks clean). Check the new seal surface area matches the housing face
