Dodge Sprinter Gas Mileage

Replying to: grasspress (Jun 11, 2006 7:32 am)

Fuel quality Gas lower Ron rating more contamination
Diesel USA Quality more industrial grade,used for heavy industrial use, such as heating and mining machinery etc refined diesel for vehicular use means more refinery processing required to produce a higher more effeciant fuel
Low suplfur grade diesel is for the new Gas emission codesfor Euro 4 global requirements
Euro 5 is for Vehicles excedding 3,5 tonn part 1 delayed to 2007 but will not come into full effect untill 2013 Refineries need time to rebulid and catch up with the rest of the European nations so it can comply to enviromential green house gas emission controls Katrina caused massive damage to all faciltys down in the Gulf and Port Arthur infurstructures.
If you stay with straight Diesel and add an upper cylinder lub then you will have no issues and reasonable mileage to the tank changing of filters will be more frequent.
The Ronnal rim is the only aftermarket rim that complys for the sprinter world wide its a heavy duty rim designed for light truck four whell drive configuration you have one inch to play with on the front whell arch when turning into full lock, low profile tyes will fail under load or at high speed because of the lower ply rating of the tyre so get the best information you can from your after market dealer and double check with Dodge if your still under warranty high wheel bearing failure can result from fitting poor qualty aftermarket products.

according to research, look for a Cetane (CN) rating over 45 (50 is a (good) normal value for premium Diesel). Anything over 50 will probably not show an improvement as good diesel is GOOD.
 
Conversly, problems are not likely to set in for CN values near 40-45. Below 40 you may get worse results, especially in cold conditions.
 
In the old days, I remember truckers talking about winter diesel and summer diesel. This would be lighter in winter for a lower cloud point (less parafinitic hydrocarbons, parafin), and more parafin in the summer for better lubrication of the injector pump. Hotter heads use lower Cetane fuel better and CN rating means less in the summer than it does in the winter.
 
Still looking for CN ratings for bio-diesel if this is in anyway standardized?

Bio Diesel ratings depending in which state you live B5 is the safest for modern diesels there is a world wide problem addressing cheaper and cleaner fuel teconology as to supplying crops for conversion into as an aditive for fuel to reduce natural oil supply demand.
Mercedes Benz is the only manufacture to meet both Euro4 and Euro 5 specifications the USA is stalling on the latter up to 2013 before it becomes totally mandatory for all US States
Refinerys need time to comply nothing is that easy I guess.
Its Interesting to note Mercedes did the research for long term fuel alternatives and that makes real sence when you look at the catalytic converters they are now using.
The statagy is for Syntethic Diesel Oil and Natural LP gas
a clean hot burn, very little or no gas emissions and cheaper to produce as there is still high reserves of HP gas to be found world wide, just remember Diesel is the stepping stone into the futre of the next engine that will not be reliant to fossil fuel.
If any of you folk take it seriously , your supply will come direct from Canada as there are trillions of gallons of sand salt bituem based fuels available, Alberto alone supplys 10 percent of fuel to the United States, forget about the Middle East its just not worth it.and no offence meant by the statement, I know it's a sensitive issue.

If I read the non-hyped parts of the web stories I can find on bio-diesel and SVO (straight vegetable oils) fuels, the best diesel is the soy-bean-oil ethyl ester bio diesel.
 
First they take out the proteins (lowers cetane slightly, is a contaminate) and glycerine (too valuable) and then react the oil with ethanol. Methanol may be used, but the resultant CN number is a little lower (maybe only 45). As the ethyl ester of soya, the CN is 50-67 (from many independent sources).
 
Bio-diesel is credited as being higher cetane rated, having better lubricating properties, cleans the fuel tanks and lines (too well to switch a dirty old diesel to it without a lot of cleanup and frequent filter changes), does not seem to require additives, and is practically edible (I assume this means an ethanol ester, not a methanol ester, but the citation mentions that it would take litres (three litres I believe) of it to cause death in 50 percent of people ingesting that amount). But then again, my Great Grandmother Roebuck used to give her kids a dose of coal-oil now and then and they all survived it. Sulfur in vegetable oils or animal fats? I don't think so, unless you saute' them with onions first... just a joke.
 
So, altered3, why not bio-diesel? please be specific, don't hype it up or gloss it over... just the facts.

bio Diesel is just not a commercial viability when you think of the volume of vehicles on the road in the US, it will work for smaller populations with land base to grow the crop
Sugar and hemp followed by corn has the hottest burn
long term short fix for fuel has to be Synthetic ! Its the only fuel that a refineray can make with the least expence involved, apart from replacing pipelines to cator for high pressure LP Gas, we all grumble about fuel and you will laugh at the STATEMENT oil companys are in this for a buck as any enterprice is, but their profits are not high enough to justify the costs of new refinerys and teconolagy, thats the sad truth. govenment regs dont help but they make more profit from fuel tax and taxes paid in by all others sources to produce the oil based fuels.

The most simple method to put single wheel rimes on the rear is go the wrecker and put the compleate unit in, you would need to change the front hubs to match.
check the weight configuration as to loading limits? with your county clerk, you should be under the two ton mark same as a car such as a DCX 300 that does not add up with residential parking restrictions. the Sprinter is a cargo and passenger van not a truck,

My sprinter is the mid based single wheel unit, I have had a similar issue with parking in resindential streets as to loading limits these vehicles are under the two ton limit and in fact weigh in less than an ordinary vehicle such as Chevrolet caprice Chrysler 300 series or the larger Fords, your direction is to find out weight limits? with out letting on what your up to. its called entrapment but what else can you do! When dealing with county regulations bogged down by red tape. If there is a weight limit = X unknown, to the regulations! If any? or is it because the vehicle is over length, the dual wheel places less pressure on the ground than a single wheel unit as the dual wheel distributes the weight over a larger ground mass area.
Getting the New Sprinter, not that easy? I only found out yesterday, that there is no AD Blue additives in commercial quanity's in the US yet, but also no oil that will be pure enough to meet the new standards, I guess you can use a lesser 10/40 oil but with a micro filter of 5 they will be blocking filters at twice the rate as its a more contaminated oil in simple english, but the AD-Blu is criticial for the gas emission to eliminate Hydrocarbons Carbon monoxides NOx and particulates etc.
Even the currant Sprinters oils are not 100% compliant
I have sent a sample of Castrol 10/40 in both standard and synthetic oils, and a sample of Mercedes Benz oil that can only be purchased at the dealer, to see what differnces there are! this test will be a University test somethings not right with the En rateings of 2007 to Euro V standards?
