Oil change question

[thstone]

I never even look at the electronic oil gauge. The dipstick will never lie.

While it's true that the gauge can be misleading, the dipstick is even more so. If the engine is cold, what you read at the stick, is a good measure. If it's hot, it's no more accurate than making a guess. Also, the stick does not measure what is or is not in the oil filter. Yes, the stick is a safer bet but, it's still a bet.

How can a physical device taking an actual depth measurement of oil be misleading?

When the engine is cold and all oil has drained to the pan, is the ACTUAL measure. When hot, the measure on the dipstick is the operating level as the cylinder heads contain oil.

The oil filter is always 100% full so that is irrelevant after the first start after an oil change with a new filter.

The oil dipstick is a bet????

Yes, it's always a bet. Fluid dynamics come into play here. While the flow may be constant, the level within the filter is not. The best you can hope for is a close approximation of the current level. In plain language, a guess.

I see the problem here.......If your fluid is dynamic, then shut the engine off to check the oil.

Flow is not constant, changes with RPM.

Plain English, Guess again.

I don't have any special knowledge here, but when the engineers start arguing theory with the software designers, the pilots stop listening and just look it up in the book.





No noted difference in capacity between the 2.7L and 3.2L: 8.7 quarts/8.25 liters with filter change. (pg 242 in the '03 manual).

Dammit man!!! Preemptively banned from facebook !!!! How will I ever learn skills such as taking selfies needed to effectively post screenshots of pertinent data????

Not sure if Thanks are in order or not????
