*How low can you go on E? #Gas

Hi guys, so I normally fill up when I see the fuel light come on. This time it came on when I was 30 miles from a Costco gas station and decided to chance it (averaging 16/17 mpg). I had read that you are normally ok until the needle goes halfway on the “E” per what I read on the forum. My question is - how low does the needle go? Also, I calculated that I had +/ - 1.64 gallons left in the car as the pump stopped at 14.26 gallons when I filled up.

If going by your 16/17 MPG then probably 25-30 miles.

No experience with this.. but..

30 miles when the light came on.. with 1.6 gal remaining..
16 miles a gal you said, so 1.6 gal would be 25.6 miles..

30 miles to the station plus the remaining fuel amount added would of been 55.6 miles..
for you atleast..

But you know, I have no idea really.

this is a bad practice, fuel keeps the pump cool

*Don't run the car with fuel light on* I installed a new fuel pump a few weeks back due to having an issue that the forum suggested a new pump was the remedy. My understanding is that the fuel pump is recommended to be changed every 100k on the rx8 and I am at 105k. Although it was time to change it, running the car with the e-light on the regular probably shortened the life of the pump. Only reason for doing this on the regular was because I put in a 8oz bottle of premix when doing a full fill up of the gas tank. Since installing the pump; I will measure premix for either a 1/2 to 3/4 of a tank. Just wanted to share this info in case anyone else is doing the same mistake I was doing.
