I have an 04 with just under 60k, was wondering if I should have my local dealer do a compression test yet? It doesn't feel down on power, but then I have been reading about people who tested with too low numbers although they said it felt normal as well. Maybe I have been gradually losing power and haven't noticed?

I do my own oil changes, and I have a greddy oil pan, I wonder if that is enough for mazda to deny any replacement should it test low?

As long as you have receipts for all your oil/filters and have them in good order then they shouldn't deny you if it turns out to be a bad engine. They would have to prove the oil pan was the cause of your engine failure to deny based on that. I really doubt they could.

I know quite a few dealers dont even do compression tests any more, hopefully the ones around you do.

Are there any reasons you would think compression is low? Low gas milage? Hard Starts? Trouble restarting when warm? If not then I would say no.

There's never a bad time for a compression test.
I do a compression test once a yr., just for piece of mind.

Your need to to show a record with receipts for the oil changes.
Oil pan will effect your warranty 99.9% of the time. Never mess with anything attached to the core and let the dealer see it. You'll be fighting an up hill battle.

not trying to thread jack but what if you have the bhr ignition coils? would that cause the dealers to deny you the replacement?

depends on the dealer.
