#22 of 76 More on gas mileage vs. wheelsize (#602) by grasspress Jun 11, 2006 (7:32 am)
hello, sprinter drivers: i've done some more research on the question of wheelsize and mpg. i was wondering if i could get better mileage by switching to the 16" wheel (my 2500 sprinter has the standard 15" wheel). evidently, any change in mpg would be negligible. the reason is because the new tires for the 16" wheels make up any difference in the 'contact patch' (the distance the tire travels in one turn of the wheel). to maintain the integrity of the braking safety features of the vehicle, tire manufactures design tire profiles that maintain a similar 'contact patch' with any change in wheel size. the tires for the 15" wheel have a greater profile than the tires for the 16" wheel, thus the 'contact patch' is nearly the same. with this in mind, i can save the extra investment of new wheels since it won't produce any noticeable savings in fuel costs. also, i'm hearing a lot from you guys about the quality of diesel and mpg. i buy my diesel at the pump at regular gas stations here in the usa. what should i look for on the pump label. i read the owner's manual and am following their warnings to stay away from bio, and the typical advice about fuel supplies in the winter, but other than that, i can't see much difference on pump warnings (except now we're getting information leading up to the new diesel sulfer regs due to be in place 1.1.2007). thanks, dave Replies to this message: altered3 (Jun 11, 2006 8:35 pm) kenbaker (Jun 13, 2006 2:27 pm) altered3 (Jun 13, 2006 9:12 pm) kenbaker (Jun 15, 2006 7:29 am) and 13 more...

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.

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