Change engine oil light is on. Occassional goes out while driving. Start up and at idle the light stay's on? I'm thinking it may be the oil sending unit? Don't really know? Your suggestions? And the location of the pressure sending unit?
when did the engine last have oil and filter changed ? this is what warning light tells you it is time for it ? do this first b4 possible damage is done to working parts of engine as for oil pressure sender unit if you check the lights on dash the oil pressure light is a seperate light which goes off when carengine is started this light may be green or yellow ?as on uk cars so if this light comes onwhils engine is running it may be a serious problem in engine or the sender for oil pressure may have failed either way i t would be best to have oil pressure check for confirmation ? after you change oil and filter ? hope this helps?when did the engine last have oil and filter changed ? this is what warning light tells you it is time for it ? do this first b4 possible damage is done to working parts of engine as for oil pressure sender unit if you check the lights on dash the oil pressure light is a seperate light which goes off when carengine is started this light may be green or yellow ?as on uk cars so if this light comes onwhils engine is running it may be a serious problem in engine or the sender for oil pressure may have failed either way i t would be best to have oil pressure check for confirmation ? after you change oil and filter ? hope this helps?
are u sure this isn't the oil level light and not the pressure light , u have both in this car.are u sure this isn't the oil level light and not the pressure light , u have both in this car.

Re: Change engine oil light is on. Occassional goes out...
If it says "change engine oil" then its just a service light.Check your oil level and oil pressure and reset the service indicator[No Buicks in Ireland so i dont know how to reset it Sorry]

the oil sending unit grounds out the dash light bulb as engine speed increases the pressure rises and turn light off normal idle hot oil pressure 30-40 psi. if low then engine bearings are worn.
It sounds like the oil sending unit is bad. the safest way to check it is to pull out the sending unit and install an oil pressure gage directly to the motor start it up, bring the RPMs up and see what the oil pressure is. Ideally you want at least 15 psi at an idle and prefereably anything above 25 psi at crusing RPM.
The Oil light is a dreaded sight, especially at idle. Usually if an oil pump fails, it dies, the same with an oil pressure sender. I had the same problem with a 97 neon, at idle the oil light comes on... (192,000 miles). If the oil used at the oil change was a thinner viscosity than what was in there, that could cause it. If not, it could be bearings going bad on the motor creating a low pressure situation. I fixed it by going to a thicker viscosity, from 5w-30 to 10w-30, and in a week the light went off... this was 7 months ago. Just food for thought, hope this helps.
there is always the possibility that you really have low oil pressure when you get this light, at idle the engines oil pump produces the least pressure and if there are problems then that is when it shows up, so have the oil pressure tested by a shop with a mechanical test gage, if the oil pressure is within spec then replace the oil pressure light sending unit on the engine, I don't recommend you drive this until u are sure of the pressure, u can SEVERELY damage the engine is the pressure is really low.
engine oil pressure may be low remove oil pressure sending unit and install a pressure gauge check for pressure while warm if pressure is ok replace oil pressure sending unit oil pressure at idle should be between 5-15 psi at min
when you press the brake pedal the brake master cylinder vacuum booster takes vacuum away from the engine and that slows the idle speed just enough to trigger the low pressure oil light. Pull the oil pressure sending unit out and hook up an oil pressure test gage, if the pressure is above 15 PSI hot engine idle in drive replace the oil pressure sending unit.

are u sure this isn't the oil level light and not the pressure light , u have both in this car.
