I got my oil changed about 2 1/2 weeks ago and about a week ago my car started running rough, i attributed it to maybe a tankful of bad gas. this morning the engine was knocking and i made a mental note to check oil. on my way home from work, the oil light came on and i stopped at a gas station immediately, (luckily i was at a corner where there was one). the dipstick read NO oil at all!! so i put in 5 quarts and the oil light has still not shut off. it is knocking but not as bad. my question is if they did not put oil in my car or something was not sealed tightly( filter or bolt) wouldnt i have blown my engine by now? i drive ALOT. and the other thing is shouldnt i have seen a puddle of oil if it is a leak? PLEASE HELP

How long did you drive the car when you noticed the low oil light came on? Also if it was the oil drain plug (wasn't skrewed on correctly) it probably leaked slowly. If you have a blown engine you wouldn't be able to drive the car at all. There might be some internal damage in the engine if you still hear knocking.

I would go back on the oil change place, but based on past experience u will have to most likely sue them to get them to fix your engine, which by the way is toast as we say in the business.
