Range (Miles to Empty)?
What do you all think about the projected range provided by the MID? I filled up my TLX gas tank the other day after running it unusually low - I think it said like 5 miles to empty - and got to thinking about the accuracy of this calculation. The tank is 17.2 gal. I was able to put 15.5 gal in. That means a buffer of just over 1.5 gal or about 40 miles at 25mpg. I know manufacturers do this for a reason, whether conservatism, engine protection or simply to avoid customer irritation from running out of gas. Our Odyssey does something similar, but I don’t think it actually says any less than 20 miles. It just drops from 20 to 0 if you go that far. Still, I don’t recall putting much more in than 18 or 19 gal in the Odyssey, which is a 21 gal tank. My old 2010 Prius was when I first noticed this practice. The fuel tank was 11.9 gal, but the range said 0 after using 9 gal or so. The reserve was over 2.5 gal, so I was totally safe regularly driving 80 miles AFTER it said 0 miles remained (common Prius owner practice)! The Prius owners manuals said such a large reserve was required to protect the hybrid system and avoid the risk of draining the battery if driving without gas. I get that. But when driving a standard ICE, isn’t it more practical to know the actual range? As in, if MID says 0, this car is literally going to stall at any second? Is the 1.5 gal required to fill lines or hold vacuum or something? |

There is a Seinfeld episode involving Kramer and Puddy(isn't there always) that addresses some people's need to test the limit of how long one can run on "empty":)

My Kia Optima won't make it to full without clicking off at 7/8 tank. I must top it off, and even then, I can only get it to 19 gallons in it's 18.5 gallon tank.
My RDX is a lot better, it always goes to full, and if topped off, can reach 19+ gallons on it's 18 gallon tank. I've heard of 7G Accord owners putting as much as between 19-21 gallons in it's rated 17.1 gallon tank. Keep in mind, once under 20 miles range, it will rapidly decline. When I first got my RDX, I had around 14 miles left on the range, then, it suddenly dropped to under 3 miles. I barely made it to the gas station, and despensed about 17 of fuel gallons in the tank. I thought I came to under 1/4 mile left on the range, however, I wasn't yet aware of the "buffer" gallon. |
