hi

i'm recently having a Oil pressure drop problem on my car. The thing is i made a long trip to NY ( 5 hour drive) and the more i drive the lower the pressure when i'm cruising. I just put a quart of motor ol like 3 days ago. so the oil level should be fine. I'm runing sigle turbo but stll using a stock gauge.

Anybody have any idea?

thanks

Probably the sending unit. Notoriously weak! I just bought a replacement from Mazdatrix after trying to go "cheap" from AutoZone, etc.

 

my oil pressure is about 15psi low normally, but can get more like 20psi low during extended interstate driving.

did the new sender fix the problelm?? holy freakin hell, it's $63 for that sender. umm, pass.

 

go to the dealer next time. mazdatrix has one hell of a markup!

 

dale clarks web site has a good right up on the pressure sender. that is your problem. oil pressure is never a problem in rotarys. youll get hit by lightning before you have low pressure

 

so i gathered.

i get all my parts from mazdaspeed motorsports anyways.

 

Never a problem with oil pressure,... yeh right!

 

I have that problem too in my 2 Rx-7s 3gen . so I'm think that it should be the sender , cause I rebuild one engine , and I know that it was compleate new , and I have the problem.
And the other one was a Pettit Racing Stage 4 engine , with everything inside with 3000 miles on it , and it have the same problem.

So It should be the sender.
