Oil Pressure

[Wolfbraid]

You could run a resistor IN PLACE OF the sensor to trick the ECM and gauge but it's not the best idea. There is a chance you might not be paying attention if/when the oil pressure really does drop to zero and you could do damage before realizing it.

Just keep in mind that the INPUT for the sensor is only 5V so don't just hook 12V up to a resistor and hook it into the OUTPUT wire of the sensor.

I probably won't do anything, if it behaves I'll be fine. Not too worried about it, like I told my wife when we bought it, I'd replace the engine in it if I had to, the rest of the vehicle is pretty top notch. I have no problem going to Jasper for a rebuilt, they'll even do them with the DOD delete if needed, as well as other options.

Yes, the only downfall of buying used, with a relatively unknown service history.
I wonder if switching to a blend or back to conventional is a better option.
Also wonder if a aftermarket solution to the oil pressure switch is a good option?

I don't worry about it too much, although I wish you could disable to warning buzzer, its integrated into the stereo.
I imagine I could put a resistor in the plug to fool the ecm and then run an aftermarket gauge...

I'm putting the old Montana back on regular oil but if it were an LS, I'd keep it on synthetic. Not sure how long that old Montana is gonna last though it is still running and getting good gas mileage. We bought it to last a year and it's been three years and she's still ticking!

Stick with GM OE or ACDelco Professional.

Decades ago, my father drove 30k miles without changing the oil in his '80 Delta 88 with a Rocket 350. One morning the motor just would not turn over anymore. No oil on the dipstick, none came out when we pulled the plug. No leaks, it was all burnt up because he didn't take care of it. My brother and I pulled the valve covers and poured a couple gallons of gasoline into the motor while cranking it over by hand (breaker bar on balancer) and then a couple of oil changes and she was running like a top again. Even beat a Z-28 on a top speed run on the highway with it afterwards! What a mess. It was around this time that I began using synthetic oil and put his newer vehicles on it and he'd go 20k miles per oil change with no ill effects on those Buick V6s.
