Surge tanks and overall fuel capacity

[p1l0t]

Also my '74 Lincoln Mark IV which is 6k lbs with PAX and fuel gets 10mpg and has a 26 gallon fuel tank. It goes about 250 miles before a fill up. Hows that for some math? I find it amuzing your BRZ has the same range but maybe you modded the shit out of it? I drive for at least 40 more miles after the light comes on though because I always have waze on wherever I go even if I know how to get there. (for traffic, distance, police trap info.. plus it reroutes automatically if you detour into unknown territory)

We definitely use a different fuel blend in the winter. It's needed so that the gasoline actually vaporizes in the cold and can be ignited.

I believe my poor winter mileage is simply down to an agressive engine/cat warning cycle, and a cold automatic transmission. The auto takes a long time to warmup and will not lock the torque converter when cold.

If I'm doing a lot of driving in a day, and getting the engine/trans to steady-state temperature my fuel consumption is basically normal.

1. What?! This makes no sense.

2. Aren’t surge tanks thousands of dollars?

I suppose personal labor and expensive shoe leather could factor in to the equation
if you're a powerfully built company director.

But then you'd get your personal assistant to fill up for you.

I go 360 miles/tank on 100% real gasoline and 340 or so on shell premium. fill-ups are 12.2 to 12.5 gallons going 40 miles past the low fuel light.

I actually wish I had a bigger tank. Where as I've never owned American, I have had many German, Italian and Japanese cars. All except my BRZ were rated from the factory to get around 400 miles to a tank. It has nothing to do with long trips but everything to do with having to go in the wrong direction to get my gas and wanting to do it less times per month. Once I'm at the station it doesn't matter to me if I'm there 5 minutes or 10 minutes. Another 2.5 Gal would be nice

It doesn't have to be modded to shit. I put wide, sticky tires on my car and lost a full 6 mpg. I was averaging 31 mpg in my first year and couldn't understand what the hell all these people on the board were doing to only get 25 mpg. Then mine instantly dropped to 25 mpg with the wide rims and tires and no other performance mods at all.

This car is finely balanced from the factory. You mess with the balance on this car, it's going to mess with you.

You guys would have shit with some of my old cars that had to be filled up two or three times a week.

I feel like you've said everything I've wanted to.

Never in my ownership of my FRS have I ever wished for a bigger tank. I feel like I rarely fill it up anyways.

Recently I made a trip from Scarborough, to Arthur, to Sauble Beach, to Guelph, to Scarborough on one tank. Pretty great, IMO

I got my BRZ 3 months ago. I am a conservative driver. Half highway half city. I always get to 380 miles till the light comes on. I then drive about 30 miles more and fill up with Shell 93 octane. The gas pump clicks off at about 11.3 gallons. My BRZ is an automatic.

If you fill up twice a month with a tank twice as big as the frs tank you will be spending the exact same amount as if you fill up the frs tank 4 times a month

36.25 mpg is impressive

That's one place the auto does better, largely due to the gearing...
