Mostly because the oil indicator is really an oil pressure indicator. The quantity of oil is not what's being measured. The threshold for oil pressure warning lights is usually set to a pretty low pressure. The idea is that, when the light comes on, something must be done immediately to correct the situation. Low quantity of oil is the most frequent cause of low oil pressure but it's not the only cause. If you have a real oil pressure gauge, and not just a warning light, you should get ample indication before it becomes a problem, unless the oil pump fails, which does not happen all that often. The gasoline gauge, OTOH, is a quantity measuring gauge. Len --- - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
