Quick 325 Question

[Rocky]

Sorry if this is in the wrong place.

My mama recently bought a 325XI (an 03). I think that gives it the M54B25 engine? Anyway she's all confused and up in the air about what kind of gas she should put it in -- regular, premium, etc. What's the minimum octane or best for her to use, so I can tell her and she'll be quiet about it? :p

I couldn't pull it up with a Google search, unfortunately. I don't think she has the owners manual.

premium

midgrade will work just fine if she's in Calgary. I used that in my 06 330I

but really as it is, VS. regular the savings arent that much, compared to midgrade, its even less, is it worth saving enough for a coffee once a week?

I'd rather use the proper fuel than try and save a couple cents per litre and risk something going wrong.

It wasn't about the savings for me. My car ran better on midgrade fuel, I had better mileage and no loss in power, no codes, no misfires.

At our altitude where DA is usually 4000ft+ N/A motors make a lot less power than at sea level.

Right now I only use premium for the GTI though.

i run premium on my 06 325i

Definitely use premium, don't try and cut corners.

what a bunch of douche bags , midgrade will be just fine

Your octane requirement goes DOWN as your elevation goes UP, all else being the same.

I'll make her use premium. I think she JUST saw the "premium" on the gas cap. Oh silly mama, if only you knew how to take care of a car, haha.

Thanks guys, it's appreciated. :closed:
