I was smelling oil from my car and stopped to put a container of "stop oil leak" into my car.

I think I made a big mistake. I put it in my car via the gas tank. I think I should have put it in my oil compartment.

At the same time as putting this in my car I put a container of carberator cleaner in also through gas tank.

Will the stop oil leak stuff ruin my car if I put it in the wrong compartment?

Hello,

Is the Gas Tank Full? If so you may only notice some smoking and it may run a little rough. The full tank should thin the Oil Stop Leak enough not to cause clogging of the fuel sock, filter or the injectors.

I filled my car up with gasoline at the same time I put the stop leak in my car.

You are awesome to have replied so quickly. It gives me comfort to know that I don't need a new engine or transmission!
