I'm a technician as well. I have my original fuel pump and water pump (OMFG!!!!). I get great fuel mileage. I change my fuel filter every 100K kms and use a fuel treatment probably 3-4 times a year. I haven't ruined anything and my car runs great. I've never run out of gas (don't plan on doing it ever as it's very inconvenient) and I only run really low (under 50 km to E) in areas where I know there are stations nearby, but I run it until that light comes on every time unless I'm somewhere where gas is significantly cheaper.

I have a feeling that those people who find themselves running out of gas while their OBC says they have 100 miles left are those that never let the sending unit operate in the full range of motion it was designed for (this is unfounded but makes sense from a mechanical standpoint). Run your tank low to avoid having your sender read inaccurately FTMFW!!!!

I'd rather save my hard earned money and not replace parts that are operating fine.

Not to sound like a smart a$$, and I really mean that, but that is the entire point of this thread, so most people here get that message.
You are preaching to the choir!

I got the fuel light with the instrument saying I had 50 miles in the tank. This would mean that it had approximately 2 gallons left in the tank. I probably should have just filled up, but I couldn't bring myself to pay an extra 40 cents per gallon when Costco was on my way and according to the trip gauge I would make it with 40 miles to spare.
