Fuel Survey - How Different Brands Perform

retmil46 · **Posted:** Sun Jan 08, 2006 1:16 pm

As much as the quality of fuel affects our CRD's performance (up to almost 10 mpg difference between brands from what I've seen), perhaps it'd be a good idea if we input our experience with different brands of bio and straight #2 dino fuel, both good and bad. This way, we could help steer all our diesel brethren, not just those with CRD's but VW TDI's, MB, Dodge Cummins, etc, as well towards the best quality fuel and getting the best performance out of their vehicle.

We've pretty well batted around the subject of fuel before on various threads, idea here would be to gather it all together in one place instead of having to search thru 20 different threads to find everyone's input.

First off, what, if any, type of grading criteria would we want to use in evaluating different brands of fuel? Do we want to use something fairly simple, such as "Poor - 22 mpg or less hwy, Good - 23 to 26 mpg hwy, Excellent - 27 to 30 mpg hwy, Outstanding - over 30 mpg hwy"?

Or just simply let everyone describe in their own words how their vehicle performed, with some loose standards so we can compare apples to apples?

At a minimum, I think we'd need to list the following - any mods to the vehicle that might affect mileage (muffler, provent, different oil, etc), type and size of tires along with inflation pressure, any TSB's or repairs done that might affect mileage, whether mileage is hand calulated or by overhead display, anything in the way you operate the vehicle you feel hurts or helps mileage (ie, religiously plug in block heater below 40 F).

Brand of fuel, rough geographic area you purchased it, mileage you obtained on it whether city combined or highway, any additives used such as Power Service. And when listing the mileage as "city", "combined", or "highway", describe what YOUR definition of each is, ie city = 35 mph stop and go, highway = interstate steady driving 70 to 75 mph.

What do you think?

Great Idea, I have seen major differences between stations in my area and now try to go to a particular station to get fuel. Which I have to say is easy since I can drive for almost 2 weeks on the CRD's arge fuel tank and great mileage.

Sounds good to me, I would also include info for fuel additive's and maybe bio-diesel useage.

Perhaps highway should be 2 lane 55 to 65 and then interstate. I drive mostly above 4,400 ft elev. and on 2 lane highways combined with city, which is 140 to 150 miles away. :lol:

Last tank:
Fil up with 1/4 tank of b20 fuel filled up at BP
Miles: 400
Gallaons: 17.8
MPG: 22.47
Driving mostly on 2 lane highway at 60-70 MPH with some burst of 75-80MPH to pass.
B20 was 45 cetane rating. BP dino had rating of 40.
Let you know about next tank. Filled up at Valero with Dino-Diesel with rating of 40 cetane.
This is with a bone stock 05 Sport with about 3500 miles. DNo additives.

This is going to vary state to state as some impose winter blends that kill gas mileage, I know Illinois does. :roll:

Exactly. That's why I think it would be a good idea to list at least the rough geographic location of the station, ie, city and state, along with the brand.

And as far as the definition, of "highway" versus "interstate" driving, that's why I suggested that each of us describe our normal driving conditions, it's going to be different for each of us. Even "interstate" could have different meanings depending on the area of the country, 60 mph some places, 70 mph others, some areas out west WOT during daylight from what I've heard, in CA could be 20 mph bumper to bumper. :roll:

Winter blend surely kills gas mileage... I picked up my new Jeep CRD with a full tank and I have to fill up already, and the odemeter shows only 400 km (250 miles). I'm in Whitehorse, Yukon Territory in Canada.

Jeez that far north they are probably only using #1 D instead of #2D for winter fuel.
