I have a 2003 ford explorer and have oil leaking on my front

Customer Question

The oil filter is always full of oil. It cleans the oil as the engine is running. So, the fact that you need an oil change has nothing to do with the oil leaking on the tire.

Are you 100% sure it's engine oil leaking on the tire? Also, is it inside the tire or outside the tire?

Customer: replied 1 year ago.
I positive it is leaking oil. I can see it on the inside of the tire.

I was driving yesterday and realized the oil had completely drained out. I did use a bottle of Lucas stop leak and refilled the oil reservoir with oil.

I would suspect either the oil filter itself to be leaking oil, or the oil pressure sending unit. This is the most likely to push oil out onto the tire. It has to be a leak that is being forced to get all the way to the tire.

I am not 100% sure what you mean by filing the oil reservoir, the engine oil should go directly into the engine through the oil fill on the valve cover on the engine.

I suspect though that the oil stop leak may not solve this issue for you if it's the oil sending unit causing the oil to get on the tire to be honest.

I would start the truck and look under it to see if you can actually see the oil spraying over to the tire from the engine, but I do think it has to be the sending unit getting the pressure out to there.

Ok so my oil gauge on the dashboard is fine, but if this sensor is faulty then this could be the source of the leak on my tire??
Expert:  Mike V. replied 1 year ago.

Yes, because the oil sending unit actually is threaded into the oil pump. Sometimes they rust out or split and since they are reading direct pressure, they are under a lot of pressure and the oil will squirt right out. This is about the only thing I can thing of that would actually spray oil all the way out to the tire.
