I recently purchased a used 2000 toyota corolla VE 61K, got all the oils flushed and refilled. But after about 15 days there was no engine oil in it. It was completely empty. I took it to firestone and he did not tell me what the problem was he just filled the engine oil again. But again after about 10 days the oil was completely empty. I took the car to firestone near my house(a different one than the previous one) he said there is no oil in the car, he checked for leaks, etc and said he dosent know where the oil is going!!!!
He told me keep an eye on it and check the oil regulary.
any Ideas as to what is going on with my toyota corolla??
No clue - but it has to go somewhere, it doesn't just disappear. It's either leaking oil (which can be seen), burning oil (which can be seen at that high a rate) or it's getting into another system (cooling most likely).
You might want to check the history of the car - if it belonged to a courier service for the first five years, the odometer might have been rolled back from 300K to 61K some time before it was sold to you.
Was the car previously leased? Did the seller provide any service records? If they never changed the oil you might have a "sludged" engine full of muddy dirty oil, and that will wreck them internally. People have been known to lease a car and turn it back in four years later with the factory fill oil still in the crankcase.
Or while I'm guessing, here's an odd but possible one - the Positive Crankcase Ventilation system is wonky, and it's blowing the oil up and out the dipstick... (Hey, Weird Happens.)
Park the car over clean butcher paper or a plastic tarp - it will show the drips and roughly where they are coming from. Check the radiator for signs of oil.
Clean off the outside of the engine and the underside of the car so you can see any external leaks, but be very careful with a pressure washer to not force water into any electrical connectors or the alternator or starter motor. It's possible that it only leaks under pressure while running, but that type of leak will get oil on the underside of the car.
And check the oil level once daily till you have a handle on how fast it's going away - oil is cheap compared to a new engine because it ran dry. If this is a family car, have only one person do it so it's consistent. Keep a log book. And check it with the car parked on a level surface, if your driveway is sloped more than a few degrees that will affect the dipstick read.
If you have no leaks, check you plugs. My 95 1.8 has one or more valve seals sucking oil in cylinder 4. I add a quart each 500 miles or so. It's not too common, but easy to google.
Do not go to Jiffy Lube. Go to a locally owned oil change place (some franchises are locally owned). Grease Monkey franchises are locally owned and usually very good if you can find one in your area.
When my car had 35K on it, it had the same problem. There was no smoke or any visible leaking underneath, but the engineer oil kept disappearing. Toyota dealer did re-build engine twice, finally fixed it under warranty. My Corrola is also 2000 VE, and now it has 144K on it, no leaking of engine oil ever since.
