Diesel Kleen® +Cetane Boost® ???? RIGHT!? IF SO, THANK YOU!! THIS WEBSITE KICKS AAAAAAAAAAAAAAASS!!!!
__. Yeah, like da man sed, silver bottle in conditions above freezing, the white bottle when it's below (or a chance to be below) freezing temps. I would like to think that the diesel fuel out there is good quality stuff that has all the really great performance so we wouldn't need an additive; I'd also like to think that there is good in the world in other places, too. But, in the real world, I believe that our engines will benefit from better lubricity, higher cetane*, more stable fuel, and fuel that had the water handles properly. For a few cents a tank, Power Service stuff seems to do this. I'm also pretty sure that there are other additives that also meet this "wide range of improvement" criterion (people have had good results with Stanadyne, Red Line, and others). Other people have looked at the claimed qualities of other additives, particularly those favored by truck engines, and found that they seem to only provide improvements in one or more of the performance areas that we need - not all of them.
__. Lucas may be a "broad range" treatment or it may not -- I'm not sure. But it's clear that there are a number of good treatments out there that do provide the "broad range" of improvements/protections so I don't feel the need to experiment.
(* I had advanced timing on my previous TDI, it really seemed to benefit from a higher cetane rating; it also averaged about 57 MPG over its 129K mile life. My current TDI hasn't had the timing advance set and it doesn't appear to need the higher cetane so much. However, I've seen easier starts, smoother and quieter idling, less smoke on startup, and less smoke under acceleration with Power Service in both cars. If there's any improvement in MPG, it's enough to pay for the additive. I can see some benefits; the benefits of better fuel lubricity and water handling may not be so visible but if they're "free" after you calculate a mileage improvement, then it's not much of a gamble on them, is it? Oh, yeah, throw in all the uncertainty about the lubricity of ULSD and it's response to water and you better bet that I will choose to use a good, wide-range additive).
