Wideband sensors and lead
Hi y'all,
The lead question is probably the most asked one from LM-1 users. So here goes:
According to Bosch specs the sensor lifespan is affected depending on the lead content of the fuel.
.6 grams lead/liter: 20,000 km
.4 grams lead/liter: 30,000 km
.15 grams lead/liter: 60,000 km
Typical long term average speed of a car in regular typical use (for purposes of calculating hours) would be about 50km/hr. So for the 0.6 grams lead/liter case the average sensor lifespan would be 400 hrs.
If somebody knows the lead content of race gas in grams/liter, please post it. I could not find it anywhere.
100LL AVGAS as used in small airplanes has 0.56 grams/liter lead content. So the expected sensor lifespan with this aviation fuel is about 400 hrs.
Regards,
Klaus
