Water/meth and 02 sensors?

[Dust]

Has anyone lost an O2 sensor early to water/meth, or gone a long time on an o2 sensor?

I've sprayed 100% meth pretty aggressively for about 30,000mi on the most recent car and both the factory and wideband have shown no ill affects. As they say, your mileage may vary.

No worries, I was looking for a replacement for my vq37 turbo online, and there was a link to o2 sensors. Just wondering if 70K KMs was something to worry about with mostly city driving. Been spraying for probably 7K KM

I think it depends on how hard you run the motor. One you get above 200hp/liter you are pushing the motor fairly hard. At this point you have to assume some items will become consumables, mainly spark plugs and sensors. Now plugs were always consumables, but you may burn through them faster. MAP, O2, etc, depending on the quality from the factory may begin to degrade over time.

660cc at probably bout 80hp. Just got a MBC and the injection kit. Haven't even thought about changing spark plug range yet.
