That's a good tip about using the OE Mazda filters. I'll pick one up for the next change. Hopefully its not $20 like the friggin 5 cent bolt I had to buy from them. :madgo:
I am still getting 15 @ idle, after it sits for about 30 sec or so. I had me scared for a little bit, but i haven't loss any oil and it runs great. I just need to hurry up and buy some REAL gauges.

If you do buy gauges, get mechanical oil gauge

Both gauges, mechanical and electrical, probably could give faulty readings after a time. If you don't get a good quality mechanical gauge it could be inaccurate after a while too. Same for the electrical one, but you need quality in the sender and the meter so it cost alot more to get a good one. ???



One thing I don't like in mechanic gauges is the pipe coming under the dashboard, if you get an oil leak it would be a real mess. :repuke:

I don't know which part gets faulty in the dashboard gauge but it's most likely to be the sender. How much this sender, is anyone has already replaced it? More then a mechanic gauge I guess.

I found a pressure sending unit at a local import parts place for about 40 bucks. I think Beck-Arnley makes it. Seems to work okay. I have no idea how accurate it is. I hear the oil pump on a rotary is very robust, so I'll trust the stock gauge for now. I think Mazdatrix sells sending units also.

< Mechanical gauges need no sender actually, so there is no sender to go bad in the future. A small hose goes to the gauge from a block adaptor you will have to install under the oil filter from Mazda Trix. I WOULD reccommend if you install a water temp gauge, to get a 12' sender, or just to go with a electrical water temp gauge. If you go with a 12' sender, you can use a existing hole on the passenger side of the car to run the probe thru and run it where you want along the firewall and then to the pump or the housing or wherever you want to put the sender. And of course if you go with electrial gauges, you just have to run wires.

yeah, thats what i though, i don't want to run hoses everywhere. I'll just pay the extra buck and get electrical gauges.

< It has nothing to do with a "extra buck", mechanical gauges are more accurate thats all, but it requires more to hook them up then running a wire, so you could say "Ill go the easy way out and get electric gauges" :notify:
