I've had my 8 since dec. and have yet to see my oil pressure gauge move. I'm starting to wonder if it's nothing more than a idiot light. I start my car in the morning even below 20 degree weather and its in the same position when I get to work an hour and a half later. I even changed my oil already and still saw no change. My 7 changes all the time according to temp and rpm, its also has actual numbers instead of L & H. I love my 7 with fresh oil it seems to have a little bit more oil pressure and runs a little better. I did'nt experience this with my 8 although I did baptize my engine with oil changing the filter.

P.S. Mazda did'nt want the oil filter to loosen. What a bitch the fist oil change is!

well you guessed right. it is just an idiot light.

beers :beer:

Mine does show a very little deviation when the oil level is a slot lower but very very mild only.

no it doesnt- it is only on or off. you have pressure over x psi or you dont. im to tired to llok up the exact pressure right now ill do it tomorrow(well in the morning/daytime;))

What a waste of a gauge cluster. They should have just put a regular speedometer there,or at least some gauges that work.

the on/off point is 5psi by the way.

you can get a pressure sensor adaptor from racing beat. then hook up your own guage. check it out:)

yeah, thats why the mazdaspeed gauge cluster has a oil pressure gauge in there.

no way! Regular speedometers give me headaches now. Digital only for me from here on out (even if I have to add it myself).

a working oil gauge would have the phones at the service dept ringing constantly since people don't know anything about cars in today's world.

Oops, thought the thread title said "Oil pressure guage sucks".
