I bought a 2 gallon container and filled it up with gas. I'm keeping it held down by the cargo straps in the hatch.
I plan to find out how many miles I can get out of a tank before the engine goes cough

I have posted the MSDS for it several times.
It is really nothing more than mineral spirits. As posted many times, it is an absolute waste of money.
It is about 75% Hydrotreated heavy naphthenic distillate solvent extract
Synonyms: Severely hydrotreated heavy naphthenic; Mineral oil, petroleum distillates, hydrotreated (mild) heavy naphthenic; Petroleum distillates, hydrotreated heavy naphthenic; Mineral oil, petroleum distillates, hydrotreated (severe) heavy naphthenic
(so in otherwords it is the solvent left over from cleaning cracked oil)
and around 20% Stoddard solvent
Synonyms: Aliphatic petroleum distillate
(In other words: oil vapor from boiling mineral spirits)
and the remainder is Benzene (which is a formerlly common cleaning agent found in (among other things) Urinal freshner screens). Benzene is now banned in California, so it will probably be phased out of use in MMO.

btw i was told that stiffening your suspension could help gas mileage (or maybe it was acceleration?). i don't quite remember but could it be that when accelerating, the car tilts back and somehow stresses the engine more to the point where you need to gas it a bit more to gain acceleration?
i'm not sure if i'm making sense or not.

So at very least if you are getting 300 miles for a tank, somone with a S5 should be getting around 350 if they get the same exact highway mileage as yours.
But I would be skeptical of anyone claiming 400 miles on a tank. Figuring that most people fill up when they have 3 gallons left, that would be 26.7 miles per gallon on a S5 and and 29.6 miles per gallon on a S4.
Even if you drained a S5 tank to empty (used all 18 gallons), at 400 miles you would be getting 22.2 MPG.

Koyo rad is on it's way. I refuse to put on commuter miles on my weekend car so I'm still driving the FC, I just take it easy (55mph highway)

I wish i had a backup car that was in one piece. Currently my FC is my DD and my MKI MR2 is awaiting the engine rebuild and transmission swap (auto>>manual), but i need to figure out if i want the coolant seals replaced or the MR2's engine rebuilt since they both cost about the same.

Or your speedo is off calibration.
Even the factory spec for highway at 55 MPH is only 24 MPG. Again I would be extreamly skeptical of any FC that can do better than 25 MPG

**** u caught it before i corrected myself
edit: and speedo is not off, 600 mile trips u tend to travel with the same cars for a while cause u're both doing 80mph or 85 mph, doubt every time i set cruise at 80 every other car around me was doing 78 (for example) every time

I'm in California. I got 27mpg on VERY hilly roads. Same with 23mpg at 80mph. Used cruise control at 80mph, even on most of the hills. Except the very steep ones when 4th gear became a necessity. The roads might have been more hilly when I was going 80 tough, I dunno. I always coast downhill, even if it makes me go 90mph (rare).

if your worried about the gas mileage and how to get better gas mileage................myswell sell the damn thing cause it a rotary motor=shitty gas mileage, deal with it cause it aint getting any better. If it makes you feel better I only get 180 miles max to a 16 gallon tank been like that since I bought it in 2002. So dont feel so bad.

cold air with a standalone?? or just an intake connected to the mass airflow sensor?
