Oil Pressure Gauge Problem

'08 1500 with 5.3. Hopped in to take my kid to daycare today and it gave me a "stop engine" alert for no oil pressure. I'm reaching for the ignition and it stops dinging and the alert goes away. Everything is cool. I shut it down anyway and check oil - full. No oil on the ground. Everything underneath looks fine. I start it back up and no issue. Daycare is about three miles from home. There and back and not over 45. On the way back, the gauge starts fluctuating with throttle - push in and it goes up, let off and it drops. Still no alerts. Checked oil again and full.

 

Anyone have a similar issue? I'm at 35% oil life and was planning an oil change and tire rotate this Thursday. I don't mind having it towed if needed - although my neighbor who drives a Ford will give me heck about it if seen. I work nights. Got off at 7 and have to be back at 7 tonight... good luck sleeping, huh? I feel like my favorite wife just started packing her bags...

Sometimes the senders just won't pick up pressure soon enough. I don't think the oil pump in the engine would be gone already. Sounds like the pressure sender may be getting old and broke in, though.

I have an 08 SLE crew. My oil gauge also fluctuates with acceleration. I checked the owners manual and it says it is normal

You should get movement in the oil pressure gauge... Higher RPM's will bring higher oil pressure, and lower rpm's will have lower oil pressure..... That is normal operations...

 

Sounds fluke....... Was the engine making any extra ordinary noise........ Chances are if the truck was running and it did that..... Seeing as if you have no oil pressure you and running you ruin the bearings in the engine..... Probably its aight...

 

Note engine bearings are NOT BEARING, bearings..... or at least roller, tapered rollers, torrington, etc, etc........ They have to have oil (under pressure) in them in order to keep the crank shaft, cam shaft, etc, from bumping into the bearing. If you truly had no oil pressure this would have happened...... Which probably would have round up your day.... Or at least would have mine..... Basically the oil acts as the roller bearings.... The oil keeps things moving.... No oil, it bumps and the engine ends up on the engine build table..

 

Might want to get the oil pressure sending unit checked out if you see the fluke "0 oil pressure" again...

      OCI, not when but why?

      By Grumpy Bear · Posted

      https://precisionlubrication.com/articles/oil-filter-efficiency/     For them it is a problem of $$$$ and compliance. To cover both they have to lie from the heart.    Government wants low waste oil numbers so the bar needs to be very low on contamination to met that requirement.  Consumer wants cheap maintenance (perceived cost). Again requiring a low bar.  OEM wants high margins at a cost effective warranty rate and lots of repeat customers. More low bar.  Filter manufacture wants the same thing the OEM wants. See the pattern?   Consumers are fickle and also want perfection requiring a HIGH bar. Inconsistent with all of the above. Consumers can be, when the put their minds to it, inquisitive, love winning arguments which requires some useful information to be available to support them. And this is where it gets sticky and the lies begin.    Information needs a solid well grounded point of reference if we are to compare in a useful way. There is a standard for this.  ISO 4548-12. This standard sets the particle size at a specific Beta ratio and darn few are faithful to its intent.    If they don't state the test method they change the particle size or the Beta ratio to hit a perceived favorable standard. They obscure the information in a way as to prevent direct comparisons leaving the consumer with one method. UOA's with an ISO 4406 test result. Pricey and not allot of labs willing to do the work. Lobby work happens everywhere, not just at the seat of government.

      IF,IF,IF. If they cared about quality instead of profit and this applies to any company, what a concept.

      2001 GMC Sierra - Banging feeling in steering wheel

      By Christopher Miller · Posted

      Good Morning Gents..hope everyone is enjoying a beautiful saturday morning. I have a 2001 GMC Sierra that I bought used in 2018. I am the 2nd owner and its a beautiful truck. Ive put about 60,000 miles on it and recently the front end has felt funny. Kind of loose when hitting bumps adn sometimes I actually feel a "bang" in the steering wheel. I took it to a local guy who said that everything was tight and he tightened the steering box. It didnt feel much better, so I had him replace the front shocks, which had noto been done since I bought it. It had the check enging light on so I took it into a local garage to fix that and check out the suspension. Everything is original and the rubber bushings that I can see look bad. They said everything was tight and there wasnt any play in the front end. Im concerned about the banging feeling in the wheel. Ive been driving this truck for 8 years, so I know how it usually feels and this is something new. Its a second vehicle, so I dont drive it all the time, but Im trying to use it more often. I live out in the country and some of the  roads are kind of rough and I alive on gravel roads. Anyone deal with anything like this before?

      Well, 2 no-bid contracts to donors didn't seem to result in a good job...
