Stock 1993 sc300...So I changed out my cluster bulbs and first drive I take, the yellow oil light on the tach pops on. I pull over and check the oil and according to the dipstick it's only half full.(I had the oil changed on monday) Anyway I added 2 quarts of oil and start it up, no light. Start driving, still no light, the bam lights up. I know its not leaking and shouldnt be burning oil as theres ~600 miles on the motor.

So questions...I searched and read the oil level senser could be bad. Can anyone who has run into this confirm?

The block was punched out .020 over, how much more oil will be needed? I read somewhere that these cars actually take more than 5 quarts?

Does synthetic burn easier than regular oil? Could the motor still being broken in contribute to oil consumption?

The car runs fine and makes no knocking/ticking noises.

Update: havent so much as started the car since yesterday so the oil could settle...dipstick says the oil is full and not a drop underneath the car. Sensor issue?

Sounds like sensor issue.

that is what I am praying for...the motor purrs like a kitten with no knocks. I'm thinking the light may have been coming on for a while cause I put a white bulb that worked there while I was doing my red cluster bulbs. When I had the break in oil in I was keeping an eye on the levels via dip stick and no leaks and it stayed full the whole 500 miles it was run.

Through searching I read that they arent too expensive. Anyone know a good place to get a quality one that won't cost an arm and a leg

are u sure that is an oil level sensor and NOT an oil PRESSURE sensor?

2jznosht

oil pressure warning is the red oil lamp by the gas guage...the one I got is the yellow one under the 5k rpm patr of the tach

there are 2 lights? good to know. gahdamn I am having the hardest time trying to find a fsm for our car

2jznosht

Yeah we have two...red=bad, yellow=check your oil level

Update: today I didnt see the light until about 10 minutes of driving on my way to work...got to work and oil was still full when I checked. 8 hours later not a drop of fluid under the car, oil is still full after settling, but the light comes on after about 10 minutes of driving.

Have you checked to make sure it didn't unPlug itself or work it's way lose? It's right at the pan by the dipstick and if the engine has been out then it's a good possibility.

2jznosht

Good point. I will check that tomorrow...I noticed today it comes on after about 10 minutes, then turns off again.

Just had mine built put 5 quarts in good to go then dyno came an i had to add 2-3 more quarts this is to be expected from new engine

2jznosht

Well
As of today it has been popping on and off in ~10 minute intervals...seems like it is working itself out

2jznosht

update...after enough city driving it eventually turns off(work to home is all freeway by the time the car fully warms up) If I keep the rpms at 2800ish the light will stay off. Seema the sensor is being tripped somehow, but works. Ideas?
