Car in question/history:
2000 vw jetta vr6 (5spd)
purchased in February 2004 with 50000 miles. I have since figured out that it was a leased car, so I do not know what kind fo maintenance was done on it. Seems to drive fine.
at 51200 mi:
mobil 1 0w40
new oil filter
transmission fluid
spark plugs
air filter
fuel filter
oil filter change at ~56200, UOA from blackstone ok.
At 58000 mi, catalytic converter failure, Replaced cat (warranty) and both o2 sensors.
oil filter change at 58500, added 14oz ARX
milage now: 59350

I do mainly a combo of short (
last fillup, I bought a bottle of techron and put it through my fuel system.. I'm about halfway through that tank now. Just received my two gallons of Fuel Power.
What should I do? regular 1oz/5gal starting next fill up? Some sort of 'shock' dose to start?
