well i did an oilchange and used full synthetic 10-40 and pressure went up prety good idk what kind they used where i got the oil change in arkansaw but now its good u guys still think it might be the bearing wear? or crank rod? also my oil oil had gasoline in it from when we tried turning it on from the throttle body

 

What does that mean? Were you pouring gas down the throttle body to start the engine?
How much gas was in the oil? Did some come pouring out of the pan drain, or was it just that the oil smelled of gas? Could be your oil was badly diluted, and a change took care of it. If your oil pressure stays within a good range, I wouldn't be as concerned about bearing wear like before.

 

Cool I thought so. New to the lt1 dont know munch about them

 

ya there was oil in the pan and whats a good range for the oil pressure to be at idle and at normal speeds lets say highway at 60 mph?? 6th gear

 

ok so i got up in the car and i got on the pedal a bit and the pressure went down again its a really hot day you think that has anything to do with it its only at idol

 

it will drop a little a short time after changing, the oil gets used to operating, and they do drop when warm. mine has a steady 70lbs when cold at an idle and 30 at idle when at operating temp. pull the dipstick out and smell it. make sure your not getting more gas in there.

 

I recently acquired a 96 z28. the low oil light is on and the pressure seems to be low to me. It rest at about the halfway mark on the gauge and sometimes falls a little below. I was told if I replace the sensor in the pan the light would go away but i'm worried about the pressure as well. The car has 156,288 miles and its run on synthetic oil. Any suggestions???

 

the half way mark is 50 lbs. that good presure. does it go below the first mark ever?

 

No, it usually stays above the first line.

 

should be ok. mine gets close to the first mark when its up to operating temp and in gear at a idle. thats still over 20lbs and is ok.
