How many miles to a tank 325i.

[MoreMayhem]

325i, 3.73 LSD, 5 Speed. Typically get 300 to 325 (lol) miles per tank. Last fill up the gas light came on at 344, which may be a record for me.

I get about 25 highway, 20 mixed. I have an early model so I'll get like 350 miles/tank on the highway and 240 in the city. I usually refill every 200. 4.10 diff

I just put a rebuilt head on my 325iX, and I'm currently getting just over 21mpg on my ~75% freeway commute. This is consistent with my last one, too, when it was sorted and running right. They're both 5 speed swaps with the original 4.10 automatic diffs, so that freeway cruising is around 4k rpm.

I need to get my valves adjusted soon seems like they're a little noisy.

Gotta remember these engines are old now, and as engines age, compression gets lower and thus efficiency gets worse.

I consistently get 11.5L/100km (21ish MPG) in my m20b23 on L-Jet pure city driving up and down hills to work and back. I have gotten it as low as 9L/100km (26mpg) on pure highway. but i rarely drive highway.

I have reconditioned the head on mine, and i have a sneaking suspicion it has new rings in it based on bore condition, but unconfirmed.

Oh and fuel gauges are typically quite inaccurate, mine goes up and down all the time. Only real way to get fuel economy is to fill the tank, use it up and note the milage, then fill it back up again and calculate how much fuel it took to travel your recordered milage.

That seems about right. M20s just suck on gas

I drive partial city and little bit of highway. Here's where I'm at now.

eta or i?

I have an i, 3.73 diff, cruising at 80mph, I use about 3/4s of a tank in ~180 miles which i think is about 20 mpg

City milage, sucks ass, not even worth calculating, because is just sucks...

Edit, I see that's the question is asking about an i

What kind of gas mileage does your 325 get? Preferably miles to a tank. I feel like I'm not getting what I should.
