How much was the new o2 sensor?

Remove the car and get a Denso 02

Remove the car?
Blazin, obtaining replacement parts for a Bonney, is not that easy in Russia.

If i order it via internet, it will cost about $30.
But i just came to my local gm dealer and bought it for $100 (include replacement work).

P.*. 2ALL: Yes, fuel in our country is a bit worse, than in US, but it is not leaded anyway since early 90'*.
My other car have no problems with fuel and there are a lot of people here, who own cars like Porsche Cayenne, Maybach, Maserati etc. I don't think, that all of them buy foreign fuel just because i often see such cars right ner me at the gas stations.
The only problem, still existing here with fuel is high percentage of anti-detonation additives, such as ferrocene. Ferrocene should be added in extra-low quantity to increase the octane of the gasoline, but if this additive is in greater percentage, it will have bad influence on almost all fuel system - injectors, spark-plugs and some sensors. They shoud be replaced frequently if you use high-octane gasoline in Russia.

My employer has a department that their only task or job is to test fuels available in all regions and countries around the world. The tests are done on all types of fuel from aviation, automotive, diesel and general aviation. Having access to the database I was able to check the types of fuel available in your country. Yes, I did forget about the Ferrocene contents too. However, the database does show on many of the fuels available in your country do happen to contain enough traces of lead to affect the operation of the oxygen sensor with time. Also, there is a big variation on the availability of fuels depending on the region of your country, which happens to be very vast. Based on the pictures, I can easily say that it shows the typical lead contamination damage. The Porsche, maybach and the European region high end cars are able to operate on a multitude of fuels. Their oxygen sensors are heated and the elements are build to operate with dirty and heavy fuels. As an example, DTS engine dynos, use a Porsche specific application, Bosch oxygen sensor for the recording of EGT on the dyno. These oxygen sensors have a price of around $850.00 US each and the dyno uses two. DTS choose these specific oxygen sensors because they will survive in all kinds of fuel from unleaded to high octane racing fuel, including methanol and alcohol. that is the reason why you see these high end cars running any fuel in your country. Your Chrysler engine is more lenient to these fuels because they have lower cylinder pressure; it also has aluminum cylinder heads that are more tolerant to detonation and pre-ignition. The oxygen sensor on Chrysler products is not as critical when compared to GM. I have owned Chrysler cars in the past and the oxygen sensor is completely dead and will not show a problem code.

Thank you very much. I can't even imagine to meet such interesting interlocutor! Big respect to you.

dont forget obd1 jeeps (mine was completeley dead and never threw a code, the only time the check engine light ever came on was for the bulb check)

I really have nothing to add to the coversation about fuel or the O2, except that is awsome picture taking.

I tried to get pictures up close like that of my old one, and it was just a large blurr. Nice pictures!

Were you guys getting codes or was it just based on poor mileage?

I have a 96 Bonne SLE with 69,000 miles. When I first bought the care (new) I was getting 27 - 28 mpg Highway. cant recall what the original around town mpg was like.

Now it seems Im getting 10 mpg around town. But I don't get any codes so I need to know whether you all were getting codes or just changed out the O2 sensor as part of a pm procedure.

Do you think 69,000 is too early to consider replacing the O2 sensor?

O2 won't throw codes, unless maybe if you disconnect it. Almost 70,000 miles sounds a little early for it to give out, but an O2 will probably get your mileage back up
