Hi=20 Steve;

I also have Van's cap. probes and I find that = the=20 calibration does fluctuate from different batches of autofuel, but empty = always=20 seems accurate. I've bought large quantities of fuel when doing my = initial=20 testing and found that when calibrated they would remain accurate as = long as I=20 used that batch of fuel, but as soon as a new batch was used, they would = suddenly be out of calibration. However as the tank neared to empty = accuracy=20 would improve and when the gauge read zero I would have ~1litre = remaining ( I=20 have multiple tanks so I can run tanks dry)

I've always assumed that Avgas, being held to a = higher=20 standard, would produce more repeatable results, but I just can't = justify the=20 cost, so I've never used it.
