Fuel question. Accidentally put 5 gallons of diesel in her tank. Tried to compensate by using 93 octane. Car was running rough, now seems okay, but Check Engine light is on. Did she do damage? Tom says forget about it. Ray says she may have done damage, but what's done is done. Get car scanned, so the check engine light will be turned off, then she can fix or not.
