In my state minimum cetane is 40 and it is not required that the actual rating be posted on pump. I'm sure some are considerably higher than others but, there is no good way of knowing.
How do we find out what our local market stations have? I always fill with Shell, but they too only state the minimum of 40. If BP (Amoco) has 50, I'm switching.

So, I'll stick to stations I know locally and roll the dice when traveling.
  • The car is new and I while I wouldn't mind having a higher cetane rating and pump lube to keep the noise down and be more efficient a lot of these products also have chemicals that swell o-rings and extra detergents that I'm not sure are necessary or even good for the engine.
  • It says right on the filler cap "No additives". So, I'm not going to put them in there and if shit goes south within the next 4 years BMW can deal with it. I'd rather not give them something to point the finger at. I'm not in it for the long haul anyway, I'll have a new one before the warranty expires.

Like socom says ethanol is an oxygenate added to our fuel to reduce CO and increase fuel mileage in the winter months and now more and more often. Unfortunately ethanol has no heat of combustion and produces no energy for propulsion therefore your fuel mileage decreases...similar to using power service.

It depends what your looking for. If you want added power, you need to boost more or take in more oxygen basically with an air intake or an oxygenating fuel additve. You need to look for a detergent fuel additive that will keep your fuel system clean also.

There are no fuel blenders anywhere in North America who put ethanol in diesel fuels. That is for gasoline.

I’ve been using optilube winter blend since I bought my car at the beginning of this year.. now switched to optilube xpd for the summer. I don’t use it for the cetane boost though... more for lubrication, anti-gel, and cleaning purposes... In my 335d it cleaned out my fuel system a lot, fixing a little idle hop I got when warming up on cold days. Then I really could see the difference it made when I when to replace my fuel filter recently... which by the looks of the filter, looks like it had never been changed before since it was the oem bmw filter (and my d has 110k on it now lol), but it didn’t look that bad... Only saw the difference in performance this winter though... atleast 1-2 mpg better on my 50 mile highway commute.

I just picked up a Cayenne Diesel so, I'm back in the diesel world. I haven't kept up with the additives but, I'm seeing some of those guys and apparently a lot of diesel truck guys run archoil. Anyone using it on here?

I used it in my 7.3 powerstroke, works well... but the optilube works a lot better in my opinion... especially with cold start ups. My dad also runs archoil in his 6.7 powerstroke and he swears by it.

I used to use PSDK (Power Service) but now use Hot Shots EDT (Everyday Diesel Treatment) in every fill up. 2 oz per full tank (~16 gallons).
