My iGuide disagrees with my 2020 F-Type brochure. The former says 16.6 "usable" US gallons; the latter says "usable" capacity is 13.9 US gallons. I've never let mine get near empty before refilling so I can't decide which is correct. Can someone clarify?

 

They both are correct. It's 13.9 imperial gallons, which converts to 16.69 US gallons.

 

Makes sense, but that means JLR goofed as "Technical Specifications" on Page 112 of the brochure plainly says "US gallons," 13.9.

Somebody forgot to convert.

 

It could have been worse:

I goofed one day. Tank took over 15 so I expect the explanation is correct.

It is rare but, at 75/80mph on the highway the car will go over 400 miles near the empty mark. It is rarely on the highway going somewhere.

there must be 3 gallons in reserve when the gage is near empty.
