About three months ago had an oil change at Kwik Fit. I brought my own oil (Mobile 1) and asked if they could change the oil for me. It was a routine sort of exercise. To cut the story short. I've used the car perhaps once a month. It ran fine, but there were moments, as if something was stopping the car from moving. It was like you were running, and someone suddenly grabbed your arm to stop you running. It felt weird, and thought perhaps the car needed a service. Last week, took the car out for a drive, the engine just stopped and would not start (engine had difficulty turning with lots of steam coming out of the air vents). Pushed it to one side. Opened the engine compartment, and the engine bay was completely (literally) drenched in engine oil, all the way to the exhaust/carb area. The dipstick was out and entwined on the houses. Called the AA. It transpired, Kwik Fit over-filled the engine with oil!!! The AA mechanic drained some of the oil to the correct level. Literally, cleaned the engine bay (fantastic work ) of excess oil. Afterwards, luckily, the car started immediately. The engine compartment was steamy from the engine oil until the oil evaporated.
Next time, I'll try to change the oil myself, but how do you dispose of the dirty oil?
