Oil Level Light

[Maticuno]

Under hard acceleration, the oil level light comes on until I reach cruising speed and back off the throttle.  I'm not talking about drag racing acceleration, but merging onto a freeway from a dead stop acceleration.  Doesn't happen all the time.  I recently changed the oil with 15W-40 Rotella and a healthy dose of Lucas Stabilizer.  Oil level looks fine in the sight glass on the center stand.  Only 18,000 miles.  Do I need to run it a little over full or am I having an oil pump issue?

Just a little more oil and all will be fine with the FJ world... Maybe 1/2 a quart... It is only a low oil warning, it happens up hill, not down hill. The sensor is in the sump, it is not tragic.... As you were...

As long as the light goes off when not under acceleration all will be fine. You can over fill a little and stop it but there is no real need.

Awesome.  Thank you.  So the light is a sump level warning, not a pressure warning?

Yes.

FWIW, I run mine at the top of the sight glass.

+1
4 Full quarts (1 US gal) and using the RPM oil filter adapter. the level just goes past the top edge of the glass.
Light never comes on now.

G'day,

Fot the past few months I had been having issues with my oil light coming on, at first occasionally, then constantly.  i thought I had the fault solved when I checked some wiring, then it came back.  I tracked it down to the diode.  Under the fairing, upper left frame.  Little square box with rubber cover, plastic tied to the frame.
I let it hang free, and the problem disappeared, re-attached it to the frame and it came back.  

It may be the cause of your issue as it appears when the engine is revving/vibrating, then disappears when the revs/vibrations die off.  

Perhaps give that a try?

cheers, Gareth

Yes as stated by others , add a little bit more oil .
