[QUOTE="astroboy, post: 604467, member: 4527"] The gauge between max and min is about 1 liter. The gauge only report by quarter of a liter unit of measure, meaning you are either full, or 0.25L short, or 0.5L short, or 0.75L short or 1L short. In Orion's case, I believe it's 0.25L short. The sensor we are using is some sort of submarine tech that uses ultrasonic concept: [url]http://www.hella.com/produktion/HellaUSA/WebSite/MiscContent/Download/AutoIndustry/Electronics/TI_Oelsensorik_GB_TT_05.pdf[/url] I find the accuracy is highly questionable because too many variables involved. I have even seen cases where owner keep topping up and later on diagnosed as having a faulty oil level sensor which resulted in an over-filled situation. [U]Best monitor it a bit longer, just to see if the reading is consistent.[/U] For my 320i, on every oil change, I only fill 4L instead of the recommended 4.25L and the gauge fluctuates from full to 0.75L short. I only top up when +1L warning is up, and it only happened once and that's because my oil filter o-ring was leaking. The N52 magnesium block is more notorious in consuming engine oil at an "acceptable" rate of 1L at around 8k km while the N46 aluminum blocks are having less cases in oil loss. [/QUOTE]
