    I have already checked my owner manual and it just says to "add approved oil at the next gas station" It then mentions "(page 302)" Which just describes the use of engine oils

    Stop by a dealer & ask for a tech to come out & reset the light & explain it to you

What are the steps in changing the oil in a 1986 Lincoln Town Car


1) Purchase appropriate oil filter, sump drain bung washer and chosen engine oil.
2) Prepare an oil pan, sump bung wrench and oil filter removal tool (check access to oil filter to be sure that your tool is suitable.)
3) Run the engine until its warm to hot.
4) With the car jacked up and secured, remove engine oil filler cap and remove engine oil sump drain bung and allow oil to flow out into your drain pan. Keep an eye on your oil and make sure it doesn't overflow from your drain pan.

5) Refit sump bung with new washer and tighten. Do not over-tighten, and be especially careful when tightening into an alluminium sump.


6) Remove oil filter. Oil will flow out from this filter when removing, so your drain pan will need to be under the filter housing when removing.


7) Run a smear of clean engine oil around the filter rubber seal and refit new filter. Tighten hand tight only. Do NOT crank this filter super tight as you may damage the rubber seal and even the filter casing which can impede oil flow.


8) Refill engine with proper quantity of oil. If you cannot find how much oil your engine is supposed to take, then refill with the same quantity of oil which you drained out.


9) Restart the engine while checking the oil pressure warning light on the dash. The warning light may stay on for three or four seconds and then go out. If this light stays on for longer, then stop your engine and check for oil leaks at the filter body and sump drain bung.


10) Once the engine oil pressure warning light is off after starting, stop the engine and check the engine oil level (with vehicle on the flat and off any axle stands.)


11) Road test the vehicle, driving it for a mile or two before re-checking for oil leaks under the engine bay and engine oil quantity.

Oillifter noise, oil getting sticky


Need to check the oil pump pressure or if there is a lag in pressure. You need to check if the oil lamp lights up soon after starting and if so the pressrure can be low. Also check the quality of oil , change the oil if this was not done for a long time.

The warning light fo the oil keeps staying on even after putting oil in it


The warning light is for oil pressure.

First check the dipstick, make sure there's enough oil in the engine.
If so, then there may be a problem with the oil filter, when was it last changed.
It could be the sender, is the connection good and clean.
Finally the oil pump filter may be blocked, or possibly the oil pump has failed.

The engine warning light wont go off, (Mazda 6) even after oil, water and coolant have been added. is it time for an oil change?


Yes it is time for an oil filter and oil change specially if there is a lapse of over 10 months or a mileage of more than 5000 miles clocked since the last oil change.

I need to know where the oli sending unit is and how to replace it?

Fig.: Oil pressure switch (sending unit) schematic


The low oil pressure warning lamp will illuminate when the ignition switch is turned to the ON position without the engine running. The lamp also illuminates if the engine oil pressure drops below a safe oil pressure level. To test the system, perform the following:

  1. Turn the ignition switch to the ON position.
  2. If the lamp does not light, check for a broken or disconnected wire around the engine and oil pressure sending unit switch.
  3. If the wire at the connector checks out OK, pull the connector loose from the switch and, with a jumper wire, ground the connector to the engine.
  4. With the ignition switch turned to the ON position, check the warning lamp. If the lamp still fails to light, check for a burned out lamp or disconnected socket in the instrument cluster.

REMOVAL & INSTALLATION
On the 2.4L engine, the oil pressure switch is located on the side of the engine block facing the firewall. On the 3.0L engine, the oil pressure switch is located on the oil filter adapter housing, next to the starter motor. On the 3.3L and 3.8L engines, the oil pressure switch is located next to the oil filter.
  1. Locate the oil pressure sending unit on the engine.
  2. Disconnect the negative battery cable.
  3. Disconnect the pressure switch electrical harness.
  4. Using a pressure switch socket, deep-well socket or wrench, loosen and remove the pressure switch from the engine.
To install:
  1. Install the pressure switch into the engine and tighten securely.
  2. Attach the electrical connector to the switch.
  3. Connect the negative battery cable.
  4. Start the engine, allow it to reach operating temperature and check for leaks.
  5. Check for proper oil pressure switch operation.

Hope this helps (remember to rate this answerr).

Audi 80 oil pressure light


i think from memory that the oil pressure switch is at the back of the cylinder head, if its not there it will be located just above the oil filter, these switches are very cheep to buy and can be bought from any good motor factors. You are right to suspect the switch, its the first thing to eliminate before bogging your self down with more complicated and expensive problems.
