I have a 1987 BMW 325i with a M20 engine (2.5 liter I6) with 103,000 miles.
I read on the BMW forum that my car needs a high Zinc oil. I utilized the Valvoline VR1 that was mentioned on the forum for the last 2-3 oil changes. This time I noticed on the back of the bottle, it states "this oil should not be used for extended time on cars with catalytic converters" (which my car does have).
So, with my big concern, as this car is my baby, I emailed Valvoline and I told them what car I have, that I have been using VR1 and I asked is it safe to continue using it in my car. They stated that I should not use the VR1 as "it will poison your o2 sensor." I accidentally emailed them twice and two different people emailed me back from Valvoline with the same "it will poison your o2 sensor" answer.
I am kind of stuck as I want to do good for my engine and that seems to be an oil with high ZDDP but I also do not want to harm any other part of my car.
Will using the Valvoline VR1 "racing oil" as my sole oil harm the longevity of my catalytic converter and/or o2 sensor?
Please advice.
