I am looking for an oil temp gauge on eBay, and notice some are described as mechanical and others as electrical. Exactly what are the differences between these two types? Don't they all use electrical sender?
Electrical, the snder can be replaced.quote:

If either type of senders becomes bad, does this mean the whole gauge replacement?
No comment on Autometer, I haven't kept up with gauges lately.quote:

The mechanical type sounds harder to install. But, how inaccurate is the electrical type?
Does Autometer make good electrical gauges? Any suggestions on other makers?
It costs approximately nothing to put the sender in boiling water and get an accurate calibration at 212F, or some lower but well known temperature if you are at a significant altitude.quote:

in reality they are just for indication and reference, not for actual measurement. what I mean is they will tell you that your tempeture is high or low or there is a 15* difference in old oil and new oil. They aren't really very good at telling you that your actual oil temp is accurately 215*F. the guage would cost alot more than what autometer charges for it to be calibrated and accurate.
oh, yeah, and add to my list "safety issues"quote:
