A friend of mine has a 2002 Daewoo Leganza that seems to have failed pretty badly. It seems that something in the top end has broken.
We recently put in a 5.25 oz bottle of Lucas UCL (he wanted the UCL and I wanted the bottle), but I just realized that he may not have filled the tank since then. I can't remember how much fuel was in the tank at the time.
Assuming the worst -- that the tank was below half and not refilled, and then driven for about 100 miles -- could an overdose of UCL have contributed to the failure?
In cased it matters, I do know the maintenance habits were not always consistent. Oil changes were done with Wal Mart Super Tech dino and were supposedly done every 3k-5k miles, but a few OCIs were missed and one may have extended to nearly 30,000 miles. I also recall that the transmission fluid had been allowed to run so low that there was none on the dipstick. After about 130k miles of that, the most recent oil change was with Mobil 1 10w30. Needless to say, it has never seen a tank with higher than 87 octane fuel.
I'm not looking to blame Lucas or get into a shouting match about fuel adds. I just want something to tell my friend about why his car left him and his family stranded near a bad neighborhood.
