I also just put in a bosch o2 sensor.
Why should I not use bosch o2 sensor.
What symptons will I have if the bosch o2 sensor goes bad?

I have used Diesel fuel, as a crankcase flush, in all my vehicles, for the last 45 years.
I add 1 quart diesel fuel, into the oil filler, let the engine idle for five minutes, and drain.
I then pour a second quart in while the first is draining out.
I leave it drip till it stops, replace the oil pan plug, replace the filter, and refill with motor oil.
( The last + - ounce left in the pan will burn off.)
It has NEVER ruined anything. My 86 Nissan ran over 188,000 miles before I sold it, in '03.
I diesel flushed it about once a year. And it never failed an Emissions inspection.
When you buy a canned "Oil flush" product.... you are getting the same diesel fuel,
with some additives, in a flashy little painted can, and pay 5 times the price, for 1/4 the amount.
Check this out..... Heated chemical flush scam :
Never attempt to clean the inside of your engine with one of those engine flush procedures that many shops try to sell. ( above link) If you've been diligent about oil changes there will be no sludge. If there is a lot of sludge then the last thing you want to do is to dislodge it all at once.
Diesel fuel, is simply oil that has been refined more than motor oil and less than gasoline.
It starts off as raw crude, the first refinement produces ......
Saying, that a petroleum product refined one step more than motor oil, and less than gasoline, will damage an engine, is just silly.
What ISN'T silly is that if you wait till there'* high mileage before doing a flush, you can disloge stuff that might clog crucial oil passages.
DAMAGE, then gets blamed on the "FLUSH"l........instead of the "FLUSHER"! ! !
