It is possible that my dash guage is correct when it shows my oil pressure fluctuating from 0 at idle to midway (40) while driving? Seems like if the pressure was truly 0, then she'd be dead by now... R/R sender?

 

Thanks!

That's very typical. The sensor just doesn't have enough resolution to accurately gauge what your oil pressure is. The owner's manual even says its normal to read 0 at warm idle.

 

If you're worried about oil pressure, get a mechanical gauge.

Makes Sense. Cool. Cool. Thanks!

Juspa,

although I agree with Mike

 

I have had good luck with changing the sender unit.

 

Also in your climate I would give Castrol 20w/50

a try.
