My car has a manual transmission.

Hi there - adding a quart of oil to your fuel tank will effectively do the same thing as putting diesel fuel into your tank. The engine will quickly foul the injectors and plugs, clog the catalytic converter, and stop running altogether. Yes, it will create blue smoke out of the exhaust, but not for long. Then you will have to drain and flush the fuel system, re-fill and prime with straight gasoline, replace the clogged catalytic converter, and..... Not a good idea!
