I have a question for you; how many liters of fuel have you ever put into your TL at any one fill up? I ask because I've only ever put more than 55 liters in my TL twice (55.112 liters and 56.338 liters). Given how aggressive the fuel gauge is on the 3G TL (i.e., it shows empty way before the tank is even approaching empty), you probably won't notice the missing 4-liters of fuel.

I have actually put in just a bit over 60 L at one time when I was literally driving on fumes. The TL is listed as a 55 liter tank but there is an emergency reserve of about 10 L, which bring it to a total of 64 L or so.
A 55 L tank gives me 600 km or so, and additional 10L would give me about 100km.
Are you saying there is an additional 10L resevoir in the tank which brings it up to 70L tank total?

You should stop driving till fumes.. You're going to wreak havoc on your fuel pump..

Hmmm, here in the U.S. they advertise the tank as being 17.2 gallons (plus about a 2-gallon reserve), that means the tank is 65 liters. I wonder if Canadian TLs have a smaller tank than here in the States.

was one time because of a city tornado and all the gas pumps were closed.

My RDX is 55 litres.

do you get at least a weeks worth of normal driving in one tank or do you fill up often?

I get on average 530 Kilometers per tank when the refuel light comes on. This is mostly highway but some city.

Fumes but not sucking air. No big deal since it isn't a diesel.

I usually fill up at 57 to 59 liters with a max at 61.53 liters once. The tank is bigger than advertised is my guess.

^ My above comment has me thinking of another thread I started on this forum as to why it takes forever to fill the last gallon or two in my RDX tank.
Comments came back stating my emissions canister will fail since I am over-filling it, etc.

Well my Honda CR-V that I bought new in 1999 and was sold to a friend in 2013 got filled the same way...right to the top (I hate stopping for gas).

Its emission system is fine (our cars got tested) and the fuel pump is still original at over 300K kilometers (>186K miles).

Just saying.

While it would be nice if my 2016 had an 18-20 gal. tank I don't find it much of an issue. Probably because, for whatever reason, my FWD RDX gets great fuel economy for a 279 hp crossover with a V-6. Generally I get 27-28 mpg in normal day-to-day driving. So if I drive it close to empty (which I seldom do) and put in 14 gal. it gets me pretty close to 400 miles.
