That is good oil pressure, just make sure if it's cold, you let it warm up a bit before putting it under a load.. if you notice a spike in pressure when you first start driving, just take it easy for a bit until the pressure normalizes.. too much pressure can be an indicator the oil is not up to temp yet.

Use 5w30 temps below 30degreed F 10w30 above 30 if u got 50,000 miles or more just stick with 10w30 at any temp
i recommend valvoline , used it for lots of years in all my vehicles never had a lubrication issue or failure
new motors w\ low miles need thinner oil 5w30
older moters w\ higher miles need a thicker oil 10w30

The oil you took out was probably a lighter weight. A heavier oil will show a higher oil pressure. Make sure you are using the proper weight for the temperature conditions in your part of the country.

Not to worry, change the oil and filter. Remember, you changed it for a reason and expect there to be a mire precise reading.

Could be the type of filter you used. The mid to high quality of filter you will notice a difference in oil pressure.

Did you put in the viscosity that the oil cap says to use ? regardless of miles , use what is recomended by manufacturer , it should have a :change oil soon lamp that comes on when oil life is low ,if pressure goes below 35 at idle i would worry , 3 to 5 k miles is normal service interval , but regular oil is only basic protection , it will not hurt to use synthetic blend or 100 % synthetic .

Sounds to me like it had just been a while in between oil changes. Be sure the oil level is correct and keep an eye on it until you become comfortable that it isn't burning oil. If the truck has high mileage, check at every fill up. hope this helps.

It may have been a long time, or There may have been the wrong oil in the engine, or gas may have diluted the oil. My 4.3 use to run about 55 after change and get to 50 in 4000 miles at next change. One word of caution on that 4.3. DO NOT LET IT OVER HEAT! I did on mine and it cracked the right head in 3 places on number 4 and 6 cylinders 1 crack on 4 and 2 cracks on 6, caused by a heater core blowing out. Drove it 3 miles with no water and fried it but with 287,000 I don't feel to bad. Would have walked if could but am on oxygen 24/7 so that was out of question.

I dont want to be the one to bring you bad news, but you most likly have engine wear. Bearing clearances, oil pump clearances all are getting out or tollarences. you can improve this by using 15/40 mptor oil , or heaver, but that is a patch. for a long shot change the oil presure sending unit or better yet use a mechanical gauge to verify the true pressure

How do you get change engine oil to disapper?


2002 to 2006 Chevrolet Silverado
  • Insert your key into the ignition, and turn it to position "A" (Run/On) without cranking the engine.

  • Depress the gas pedal three times within five seconds. The "Change Oil" message will begin to flash.
  • Turn the ignition to position "A" (Lock/Off) once the light stops flashing (about 10 seconds).

    Is the oil gauge in a 2006 1500 4 x 4 silverado suppose to at 80 all the time?


    80 PSI is within operating range, but all the time would suggest that it stays there even after you turn your engine off and does not increase incrementally when engine is first turned on. If that is the case you have a faulty oil pressure sending unit or a stuck gauge.

    Oil leaking from engine right at the top of the bell housing?


    it sounds like your oil pressure sending unit has gone bad. It is on the top back of the eng. close to the fire wall. If you don't have a good tool to take it out you could use a plumbing stem puller. It worked great. proper size is 1 1/16
    Good luck and hope this helps. When replacing the oil sensor, make sure you do not use and teflon tape or silicon. The sensor is tapered and need a good ground to the engine to get proper readings.
