Oil Warning
One of the first idiot lights, the warning light to the far left, featuring an old-school oil can or what could be even Aladdin’s lamp, is the Oil Warning Light, either level or pressure symbol. A wavy line below the oil can is more specific and indicates the oil level is low, as seen in the second symbol. Without the wavy line, your engine is telling you that the oil pressure is low.
- But first, is one of these truly your symbol?? If yes, continue on below.
- Otherwise return to our main Picture Symbols page and scan again!
So, what do you do next?
In either case, the oil level must be checked. The text symbols Oil Level or Low Oil Pressure are used by some manufacturers and is also an admonition to check the oil. In either case, if the oil level is good, the engine needs servicing as soon as possible as an oil pump failure is likely and will lead to serious engine damage.
This is also a Low Oil Pressure Warning Indicator. The exclamation point in the warning indicator, accompanied by a dial and a pointer, indicates that the engine’s RPM has been reduced. The dial and pointer are intended to be a gauge, however, there are no markings to indicate actual oil pressure. As with the text messages above, low oil pressure can result in serious engine damage, even at reduced RPMs, so have the engine serviced as soon as possible.
This one is an Oil Temperature Indicator symbol. It adds a thermometer above the image of the oil can. It is found in vehicles with high-performance engines that may be run very hard. If it is seen on the instrument panel, pull over and shut down the engine as soon as possible to allow it to cool down.
