Regular or Premium fuel?

And what are the pros and cons.

I seem to remember that this has been discussed before....perhaps when the E9x was new. Let's see what Google brings up.

Hi - Welcome! Wish I had a BMW at 17 - good for you.

Answer -

Premium gas if:

- you can afford it.
- want the power your car was designed to achieve

Regular gas if:

- you are on a budget
- you are not overly concerned about performance

I use Shell V Power 93.

You pay about 10% less for regular but get about 15% less in the way of performance and MPG. The engine has to work harder to compensate for the lower octane of regular. Bottom line, you probably won't hurt your engine but you aren't saving any money.

Go with premium and enjoy the extra performance.

I use Shell V Power also. But if you stick to any top tier supplier you'll be extra safe because of the additives they use. Don't trust the local discount station.

Here's a link on toptier.

+1 Cal....For some reason (maybe the 300th time this has been asked), I think it may be time for it to become a Sticky on the top of every forum. As Kat made a great Sticky on how to find topics that may have your answer already.

Wow, 17 and "of course a BMW". I had to buy my used POS '81 Dodge pickup.

BTW, congrats on the car and welcome to the Fest.

Mein Auto: JB4 335xi Coupe
i will NEVER put regular in my car, i always put the highest octane they have, i also like going to sunoco too....but when i'm buy the LUK OIL about 10-12 minutes from my house i put CAM 2 in her oh i drive a 335xi coupe ...i recommend you NEVER put regular gas in your car, always go for super, 93 or 96...i know some gas stations have 98 as super and some have 92....but usually i see 96 and 98

EDIT: i guess you guys call is Premium ? i thought the highest octane was super, i thought it went "Regular, Premium, Super" i may be wrong....

Regular is inefficient, just go premium, it's better in every way.

Since BMW doesn't publish power or economy figures using different octanes in the 328i, where do you get your 15% figure?

A few years ago, BMW did claim that their R1200 motorcycle engine would develop 8% less peak horsepower when run on 87 octane. Whether this applies to a 328i is anyone's guess.

In real life, the difference in my 328i seems to be less than 10%, so I fill with 93 octane unless it becomes 10% more expensive than 87. If I were tracking the car, I think I'd stick to 93, but for a DD, I tend to go with whatever is most cost effective.

Tom

If you have to ask, you ned to sell that BMW and get a Civic. They are designed to run on cheap gas.

This is discussed every week. It's a shame, I thought 17 year olds lived on their smart phones and knew what a search engine was ... times have changed.

Well, you got to decide for yourself.
But, I track my mileage. I have seen various studies over the years that indicate power/MPG loss negates any savings at the pump. My findings confirm that. I realize everyone's driving is different, so I experimented with reg vs. premium in my e93. Got a little over 10% less in MPG. Similar results found in an old Nissan Pathy and my wife's X328i.
On top of the MPG reduction there was a noticeable difference in response. I had to feed it more throttle to get to speed--which no doubt contributed to the mileage loss.
You can go with the most "cost effective" choice. But the other thing to remember is that almost all suppliers use a different additive package in their premium products. That alone will keep valves/fuel system cleaner and more efficient. IMO, all things considered, not worth sweating over an extra $1 or $2 dollars at the pump.

What's the big deal? He's got a new car and wants to learn how to take care of it. He came to the right place. Don't discourage him.

I read as many threads as I could, asked when I couldn't find what I was looking for, and bore the wrath of those who assumed that I hadn't tried the search button!
One must learn to have a thick skin in order to survive on a BMW website, as most BMW owners can be a tad harsh.

I guess. Sometimes we forget what it is like to be 17.

The thing is, it doesn't hurt to ask. Even if you perceive some people are too lazy to search. If someone does want to read the thread...don't. If you answered the question 100 time before and don't want to be bothered...don't.

I just don't think it is that big a deal.
