What's the best mileage on a 325/328 you can get?

of course these are not scientifically accurate or anything, but I made the effort, mainly because I was curious, but also because I was bored.

That actually doesn't make much sense, unless the motor was so highly tuned that it detonates on anything less than 94 (which would have to be a seriously aggressive map/compression ratio). The Sunoco 94 is 10% ethanol (as well as the 91 in most other stations) while the Shell 91 has none. This tells you right away that the Shell 91 will be more efficient.

And for the record, I did the same test in back to back tanks in my M3. The Shell 91 consistently averaged around 50km more per tank than Sunoco 94.

I fill my car with 91. I usually get 450km to a tank. The other week I went up north and I averaged 570km, although I wasn't driving very economically. I have a 98 M3.

The only place i fill up is Shell or Sunoco

I still can't beleiev the numbers that i'm hearing... Mystikal - 800km to a tank???? Damn i'm jealous.

So far, My air filter is new, my fuel filter is new, maybe it's time to change my spark plugs?

What else am i missing? Maybe it's time i got some injector cleaner, that'l give me that extra 150km that i'm missing

Maybe a 1.8 swap??

yea i realize that but I still ended up getting about 25 more kilometers out of the sunoco 94....i run shell 91 whenever I can. It has proven to be the most cost effective fuel for my car.

So I filled up today.. ran her bone dry. thought I might even be a road side watcher...

anyways.. i got 615kms per a tank of esso 91.. not bad.. I filled up with Shell 91 today see if I can beat that..

by the way my car took 58L of gas... yep BONE DRY!!

[propr'one]

if you put 58L in, then you had 7L left. e36 tanks are 60L tanks + 5L reserve.

615/58 = 10.6KM/L

You could've driven another 70KM

I thought it was a 8L reserve At least i thought that's what i read from the owner's manual yesterday.

Either way, I'm too damn scared to drive my car after the light comes up

enough with the bone dry comments people, dont encourage it. you let it go on empty then your fuel pump will fail and thats 200$ right there to replace it. all your fuel economy goes out the window. i know this from experience.

So you drove 615 km before 12 pm?

[sproule905]

^^^

not in one shot.. over a week and a half...

Propr'one... 5L reserve.. from what point does this reserve kick in? when the light goes on? or when the needle is burried... not that I want to take a chance and be stranded.

[noodles101]

ive calculated mine.. 35 L and i do 280 km...
i have a 328i auto and i dont push it at all lol.
it came out to 12.9 L / 100km
isnt that badd? lol wats wrong wit myyy carrr

[sproule905]

^^ you're actually doing 8L / 100kms

280/35L= 8L/100km

[noodles101]

lol oh shit haha thats pretty decent
cuz i used the calculator thing on the internet. lol i guess i did it wrong
thxx for calculating tho
