Minimum Fuel Level

[Pop Pop]

Getting to know my Tam and unusually I let the fuel level go down to an indicated 12L on the level. On the way to get fuel traffic jam on a hill going up. Fuel level dropped to 6L and had real difficulty holding enough revs to stop a stall, and what a racket from the popping!
Filled up and problem gone.I guess the answer is to keep more fuel in the tank. Is this a known issue and have others experienced this?

You actually believe TVR gauges are accurate, I start looking fro petrol stations when they read a quarter of a tank and I have 3 TVR,s, my advice would be don,t go below a quarter of a tank made that mistake in my Griff and run out of petrol when it read half way between a quarter and empty

[Harrow_tam]

I regularly let it run down til the 4L alarm goes off. Never had a problem. But all TVRs are different - that's part of the attraction.

See Craig's thread on variance comments.

Often run my Tam down to the 4L warning. 42 litres will then fill it to the top.

Does anyone know what the tank capacity is ? The handbook says 63L but that can't be right can it ? The gauge max is 54L.

[alex_gray255]

For the Sag, the max I will take it is 56-57L.

After that it overfills which is not good...

[Targarama]

52L here. Got 53L in once. When filling mine slowly, once it clicks that's full. Any more will end up being burped out onto the floor.

My tam is pretty darn accurate to the ltr, famous last words...
But it's wonderful in comparison to the gauge on my elise which seemed to operate on a exponential scale... full for ages then all of the sudden half a tank, going down faster and faster. Not fun if you're in the north coast of Scotland on a Sunday.

Mine depends on which bend its going round. Take a roundabout at speed, 6 litres, straighten up, back up to 15 litres

[shep1001]

53 litres when full. Take it to about 4 litres if I know where the petrol stations are otherwise 10 is a safe bet. I take the reading on the move as being a true reflection of what is in the tank, static always reads 2-3 litres more

Correctomundo!

When the alarm goes on mine at 4L, I probably have about 10L left, but it is vary variable. I always run it to the alarm then about another 20miles before looking for fuel - but as others have said I'm sure each car is different.

Mine showed 1L today!

Having once run out of fuel on the M62 (not in a TVR), I've never really trusted fuel gauges since, so I usually fill up when still in double figures. Despite knowing there was a petrol station less than 2 miles away today I was still sweating. Made it fine, no coughing, spluttering or anything untoward thankfully.

They have an alarm for that!

Mine is currently showing 1L. When it hits 1L I've got 10L left in the tank. The most I've ever filled it with is 60L.

There is one uphill left hander on the way home from work where it will cough with as much as 20L left (10 on the gauge). Otherwise fine....

Ditto on both points 4L & 54L.

Mine ran out on 6l while waiting at the pump in France, was a very close call after thinking the next station wouldn't be far, ummm misjudged that one
My heart pumped hard when I tried to restart, thank god it did.

I think I've had 55l in it but know I've actually put 53 in before. Not that accurate tbh.

[mycroft]

I regularly test my 4ltr buzzer , its works just fine.
I think there is a good 10-12 litters in the tank when the 4ltr warning sounds but have no plans to test my theory.

On the way back from Le Mans in the Sag a couple of years ago, missed our intended fuel stop and had to chance getting to the next. Then ended up sitting in the queue for the peage with the gauge registering 1L. By the time we reached the barrier it was showing 0L. Air con off, radio off, dry mouth, passenger sweating (was he going to have to push?). When the barrier went up there was a nice crowd awaiting some sound effects. Sorry, we pulled away and changed up on 1,200 rev's. Made it to the next garage fortunately, but always vowed never again
