Hello all, I'm new to Mazda, but not to vehicle maintenance.
Wow, this thread is really discouraging. I bought a 99LX 1.6L for my daughter earlier this year w/47K miles and now at ~60K it still has no oil consumption. It does have a slow leak from somewhere (might be the front crank seal) and the bottom of the oil pan does get some wetness, but at 4K intervals the oil still registers at the full mark, so it is a slow leak for now. On that point, does Mazda usually use a crush washer on their 1.6L oil drains. I've done several oil changes and this did come to my attention because my Accord uses one.
It seems the only issue with the 1.6L was the MAF (I believe this was taken care of by the original owner) and possibly a weak auto tranny that may require frequent drain/refills (not a problem because of the tranny drain plug).
From browsing this forum for several months, it seems the 2.0L is more problematic.
I drove her Protege to her last May (~320 mile trip) and I must say I was very impressed with the ride and handling. And the interior and appointments compare very well with my '01 Accord LX. I was surprised, this is definitely a nice little sedan and I'll keep the "3" 5dr in mind for my next purchase, but Honda is finally bringing the Jazz over so we'll see.
