Why does everyone here have diesels?

You might think I am ignorant based on this newbish type thread, but I am on the Big Bob Oil forum, and I probably know a lot more about gas than you.

You are talking crazy talk.

But it does. Ask any BMW tech.

So if you know more about gas than all of us. Then by all means shut up and go back to Big Bob Oil Forum.

Its time to put up or shut up.

I said several times. Talk to any BMW tech. Take care.

BMW does indeed call for synthetic. That is true.

But where does BMW require "mid-grade and higher"??

True ignorance in my book.

Octane rating is one important thing. Buying fuel from a "top tier" station like Shell or Sunoco is another important thing, regardless of octane. Google "top tier fuel" for more specifics. It does matter.

Tarnish?

There is no such thing as "tarnishing" an engine, unless you are talking of discoloring the engine parts.

I think the word you are looking for is "varnish."


And it's not true.

Or you can use techron before an oil change.

Blah, blah, blah.

The diesel offers the best all-around package, imo. Yes, the 5.0 is faster but these are +5000 lb SUV's not sports cars.

Right now, diesel is $0.17 nore than Premium gas in my area. I have never seen diesel higher than 20 cents over premium.

The gas station around my home, Premium costs 4.29, Diesel costs 4.99

"Blah blah bah?" What arrogance. You are entitled to your opinion. To infer that there is one "truth" here and that beyond any debate you possess it is laughable. More civility and respect for us all, please.

On page 235 of the owners manual,,,it says not to use any gasoline below 87-89 AKI,,,with we call mid-grade...."it is HIGHLY recomended that you use super premium fuel",,or as we call it premium...good quality fuels have detergents and anti-knocj properties that possibly some lower grades of fuel do not. Around here,,,Ashland suppleis fuel to Speedway and their own Ashland stations,,,working in the industry,,,I asked what is the difference and he said between the gasolines there is none,,HOWVERE, the additive package that they use for various blends differ greatly. In other works,,,while adding anti-knock agents in the "cheap" fuel,,,,there might be no detergents in there. Thats how they manage to sell it for .03-.10 cents less.

Like I said. Just use Techron before an oil change. Its actually the same detergents used in tier 1, but super-concentrated.

I've driven BMW diesels for the last 7 years, 6 years of that was in Europe and my car was a 2000 330d touring. When I came back to the US I knew I wanted another diesel, looked at the Q7, Toureg and the MB but hey just didnt compare to the X5 so thats what I ordered. My 330dt had 290,000 kms on it when I sold it, it still ran great and I drove the snot out of it! It would still get 1000 kms per tank on the hiway when I sold it... If BMW would've offered the 5 series touring in the US I would've bought it instead but I'm happy with the X5.

I chose diesel because it felt bettet then the 6 to me when tested back to back x5's. also 16/23 vs 19/26 is about 16% economy gain yet the price is not 16% more. also bmw has a discount which matches the tax incentive of the past years so price was very close. around here diesel is 3.85 to 3.95 vs 3.65 midgrade

powered by lemings

corrected prices from gas buddy as of today: low = 3.54, mid= 3.69, hi=3.79, diesel=3.85 lowest local prices for each. no matter how you run the math diesel saves on economy.

Panties in a bunch much? Amazing how many cry babies there are on this forum.

I was referring to the ridiculous back and forth that was occuring regarding the fuel.

Civility and respect? Maybe if there weren't so many retarded posts on this forum.

This.

It's hilarious how people debate petrol octanes here. It's essentially two sides.

1. "I'm really cheap and am pinching pennies to buy a BMW, so I put in 87, even though I save nothing in the long run"

and

2. "[to other side] "You're an idiot. If you are pinching pennies this much in regards to what octane you put in, maybe you should reconsider your priorities and not buy a $50k+ BMW. Just don't go to starbucks for a day"



Another plus OP, diesel has no octanes nothing. They do in Europe where you can get "Super" diesel, but in the US, you don't.

I just returned from towing the car and trailer to Cortez, Colorado from Iowa for some suspension upgrades combined with a ski trip. The BMW towed this brilliantly even into a 30 mph headwind and through the mountains. This is a better tow car than the Touareg, and I do not need, or miss, the diesel. It will run on 87 octane fuel but needs 91 to develop full power. I was concerned with all of the niggling reliability issues with the X5 diesel, at least when I last looked at this issue in 2010. So, my vote is for the gasser.

Is what why the 35i is actually the most unreliable of the three engines? With the 35d being average. It's the only X5 recommended by Consumer Reports

The N55/N54 have tarnished BMW's reliability ratings tremendously

This is as stupid as it gets. Just put in quality gas in the first place and stop filling up at Walmart or Bob's Corner Mart.

Consumer reports hasn't tested the X5 since they tested the 2009 35d, they've done no testing of the 35i or 50i.

Looking at their survey results, it looks like the 2011 35i and 35d are pretty close when it comes to powertrain reliability.

35i


35d


Considering how the rest of the car is basically the same, I'm not sure how the 35i's power equipment or audio system came in worse then the 35d's in the survey.

I doubt if one bottle of Techron will get rid of XXXX miles worth of deposits. A lot easier to use the proper fuel IMHO. I have used Techron in the past and (I think) that it's OK. Really don't know how much it cleans out,,,unless you strip the engine down. Again,,,IMHO

I am amazed at some of the super cheap ass and overly sensitive people on this forum, I could name a couple but then they would become overly sensitive, it amazes me the debates on fuel octane , etc, if you buy the vehicle and it states that premium is recommended and you knew that why would you think anything different, Oh I get it, the salesman stated that to you and you believed him.

I find the tier 1 standards slightly contradictory.

Even though the BMW manual tells you to steer the fcuck away from ethanol containing E 85 (saying that it will mess up your engine) the "tier 1" standards mandate 8-10% ethanol.





I would rather have pure gas, and use Techron before an oil change.
