Haha, I would LOVE to know how a liquid extends the life of a filter.

Powerservice is the only additive you need.

What's magic about it? Basically all any additive does is give the buyer a warm fuzzy feeling. The chemicals used in additives are available to anybody wanting to jump in the warm fuzzy feeling supply business.

The sulfur in diesel is chemically bound, it isn't sludge. The oil in your transmission is resulfurized as are most greases.

This is simple marketing.

It must disolve out all of the dirt and grit, to clean the filter, causing it to flow through your injection pump and fuel injectors!

Sounds like just a lubricity/seal conditioner additive.

And most people never need that.

Diesel fuel in civilized countries comes with all the additives normally needed. The real advantage of PowerService is that it does no harm and in some rare conditions does do some good (other than the warm fuzzy feel)

Note: I agree that it does provide an degree of additional protection and that is sufficient to justify the cost and bother for many drivers

then why when compared to EU ULSD, people always say that US ULSD is more drier and less of a quality of diesel.. most us ULSD.. is 40-45 cetane.. lucky to find above 45... Most EU ULSD is 50 cetane minimum.. as high as high 60's on the cetane rating.... VW TDI's run more happy the higher the cetane... and with lower cetane rating,, theres less lubricity on the HP fuel pump... wears out the fuel pump must faster....

1. Lubricity has nothing to do with cetane rating.
2. Most US diesel is marked as "Minimum 40 cetane" and nothing more. Testing in most of the country generally shows it to be in the 45-50 cetane range in most areas.
3. EU standards are higher than US standards; that's why the comparisons.

Hope that helps.

I'm all over this. Must be really great stuff for the weekend warrior that misses not having to clean out they're intakes that used to clog up do to the Sulfur in the older Diesel.

Where did you ever get the idea that cetane helps prevent wear on your HPFP? Not here I hope.

A lot of people do the same thing with important maintenance and troubleshooting decisions. They will take some vague knowledge about how something function and do like Peter Pan would do and just use their imagination to fill in the blanks for things they don't have a clue about...............
