Recommendation is every 3000 but shampoo says lather rinse and repeat. never have to do that. i try to go 4000 to 5000 then change. latest recommendation for viscosity was 10 - 30 this works well any time of the year. good luck

Why is my 2002 Pontiac grand am dripping oil 1 drop every 5 seconds only while the engine is running following an oil change?

sorry would need to see it to know the problem ,but i have had it where the oil filter itself wasnt made properly and it leaks on the crimped seal on the filter .

2006 pontiac g6 clunking noise when shifting gears check engin light came on day after noise started p0014 code had it scaned by the nice atuo zone guy . He gave 4 possible causes 1 loose cam or crank...

Hey Cab4457, Please take your pontiac to a reputable dealer.. you can "hunt and peck" at "fixes" for $$$$$ and still not fix it.. better to let someone that knows how, than spend $$$$ trying to do it yourself,, this sounds a little more than "shade tree" level issues!!

My grand am gt 2003 has the "oli pressure light", light on. what should i do. what part do i need? i do not want to blow my engine up

OK, first I would check the level. Then, I might check the pressure at the oil switch using a gauge. If it has pressure there, the oil sending switch may be bad.

Or, the viscosity of the oil may be too thin, or the oil filter may be clogged which would mean that changing the oil and filter may solve the problem.

How does the engine run? If it runs without making any knocking or abnormal sounds, then it may be a false low oil pressure reading.

I would try to get this issue fixed as soon as possible, though, as these things won't get better by themselves.

Oil capacity of 2002 grand prix

Right around 4 3/4 quarts. Use an AC Delco filter. There is a difference and this will prevent low oil pressure.

Not getting oil in top half of enginge 97 pontiac transport

Fuel in Cylinder Is CAUSED Most Likley BY THE MISSFIRE Check Spark at that Cyl. & Correct that. ALSO Fuel in oil Breaks Down Viscosity of the OIL so I Would Eliminate the Fuel in OIL Problem First to Determine if No Oil Pressure in top end

Oil pressure wont stay up in my 3.1 V6

the pump filter screen is probably partly stopped up. when did you last change the filter itself?
on the pump,there is a filter screen (not the filter) that is used to keep large items from getting sucked into the pump which is located on the of the engine submerged into the oil in the oil pan.
the oinly way i know to unclog it without removing the oil pan to access the screen, would be to drop the pan low enough to get to the screen with an air line to try and blow the trash off.
it may be possible to use a reversing drill motor to run the pump backwards to try to clear the screen, but i'm not sure if that is possible on your vehicle.
someone else may have another solution.
one other thing may also cause the low pressure drop. that is the oil viscosity. what oil are you using? 30w doesn't have the same viscosity as 50w. also, 5w30 and 10w40 have varied viscosity from high to low depending on engine temperature. high viscosity is thinner for higher temps, low viscosity is thicker for lower engine temps. the oil you use may need to be of a higher viscosity if you live in a cooler climate, and lower if in a warmer climate.
