I fill up at Shell and my mileage is consistent. Hess and Mobil seem to hurt my mileage. I instantly lose up to 8mpg on Hess and my in-laws 2010 DSG got 31mpg on Mobil...

heres a link thats helpful
http://www.bimmerboost.com/showthrea...s-gas-stations

I always add into my tank 5.3 fl/oz of the Gray bottle of Diesel Kleen to boost the cetane up a little more too. 5.3 was the math I figured how on much is in the tank.

Both my 03 golf, and our 2010 a3 get the best mileage with Husky Dieselmax, + 3oz Lubecorp premium diesel plus. Petrocan, esso and shell never give the same mileage. Also use it for the extra lubricity additive package with Husky.

Anyone with a CR tdi be careful with some BP stations.
My 3 local BP stations use 25% bio in the summer blend. From what I've read it could cause fuel pump issues on 09+ tdi's.

I've heard differently, on this site. Excess biodiesel can dilute the engine oil, but the lubricity could help the CR pump.

Downside- Long term use will damage the dpf system. Upside-increase the life of the hpfp.- catch 22

...and he did say "SOME" BP stations. I haven't seen bio in the DC area BP/Amoco stations.
I daresay it won't be too long before we start reading about DPF issues, as engines start to pass the 100k mile mark. Then we can all analyze the various combinations of bio/additives that have been tried.
Hopefully, we'll find the part to be over-engineered...

Contacted BP on a mis-labled pump (ethanol sticker) and asked about Cetane and bio-diesel content. Here is the reply; interestingly according to this person any fuel over B5 must be labeled per the FTC.

Hello Gerry,

We very much appreciate you bringing this matter to our attention. I elevated it to the Jobber Sales Manager and Brand Manager.
I have been informed the label was removed by COB yesterday.

Some general information you might be interested in:
- Dispenser labeling requirements vary by state. Some having very detailed requirements while other have almost none. I don't believe OH has any particular labeling requirements for bio-diesel. However the FTC requires all diesel fuel containing >5% biodiesel to be labeled. the example below covers 6-20%, no label is required for 5% or less.



- I have attached a Product Information sheet for BP Diesel along a couple of Technical Bulletins which you may find of interest.

Thanks again for you interest in BP fuels.

Uhhhhh... Look up how oil is refined. You don't grab a tank of Oil and say "I'm only going to make gas out of it"). Basically Crude contains all the different types of fuels, which have different boiling points. They distill the crude, and capture the different types of fuel from it. IE: At the lower temps you get gas, that is captured, and stored into tank as gas, at a higher temp you get diesel and fuel oil, again that's captured, you then heat it up more and you get lube oil and so on.

Great example of the process

be careful of high turnover truck stops. a lot of time these stations have some of the lowest quality fuel. a 14 liter cummins might not mind some extra water and contaminants, but our much smaller and more refined fuel systems are much more sensitive.

2 of the 3 tanks of bad fuel I have gotten are from places where big rigs fill up

also avoid walmart/costco like the plague. I have seen pictures of tanks from there that are orange and there are large particles of asphaltenes floating in it

for the crappiness of north american diesel i recommend some aftermarket filtration. i run an adapter that allows me to use any filter for a certain CAT filter head. 3 micron absolute donaldson filters for $6.50, big improvement over 4 micron nominal and 35 dollar stocker

You may need to reduce your oil change interval, as CR TDIs with the diesel particulate filter could be at risk from fuel contamination of the crankcase oil.

B02-B05 should be reasonably safe. But VW warns against anything over B05 in the common rail TDIs.

d-man,
I was very pleasantly surprised to see that they've just started selling diesel at the Costco in Eagle CO. Cheaper than the surrounding area and i've had no problems with it although I haven't got my consumption worked out for that tank yet.

I have recently checked in with a locally/family owned fuel company about putting in my own tank so I do not have to deal with bad fuel issues. He also warned me about the truck stops. They are not in the market to sell you the best fuel. They buy the cheapest theycan find to make money. He also said the cetane is not like octane. Cetane only comes into play on start up and until the engine is up to temp. They sell regular and premium diesel. The difference in the two, premium has the additives regular does not. I am trying out their fuel now and I hope to have my tank soon.
