NEW 7 Micron Fuel Filter

[SHobbs]

In some areas the sulfur will go down to around 10ppm due to some of the old 500ppm reside that is left behind. They are afraid that the content will exceed 15ppm if they don't do it.

I just changed mine a couple of months ago, and won't be due for about a year or so.





I hope you change the fiter more often than that or your asking for problems,

just trying to help prevent a future problem.

Not if he only drives 10k or less per year.

Just installed mine. After moving from my 96' to 06' the diesel exhaust smelled different. The weird 06' smell is back. At 11k I guess the original filter was due. The outside appears about the same. The end caps are just slightly different. The biggest change was inside. The new one looks to have more surface area open to the fuel inside. Way easier to change than my 96'. Won't know mileage for sometime.

the ultra low sulfur fuel already available in some states has a detergent effect and may more quickly dirty any filter

I'm more concered about what 'stuff' the old fuel was coating my fuel system with. Another reason I went with biodiesel. It keeps it clean.

This is all just marketing. A 10-micron filter can trap particles as small as one micron. The same holds true for a 7 or 5-micron filter. All this means is that the test dust used to test the filters was either 5,7, or 10 microns in size. It is the filtering efficiency that matters regardless of the size of test dust. In other words, lets say you have a 7-micron filter that is rated at 96. 5 efficiency. Then lets say you have a 10-micron filter that is rated at 99. 5 efficiency. Which filter is better? Probably the 10-micron filter but it is hard to tell. You see, again, when the filter manufacturer says that it is a 7-micron filter, all that means is that the filter was tested with 7-micron dust and has absolutely nothing to do with how small of particles the filter can trap, or how restrictive the filter is. There is no difference between a 7 and 10-micron filter, unless the filters can be tested side by side with both 7 and 10-micron filter dust and then look at the efficiency ratings.



The filter manufacturing companies assumed that most people would think smaller is better. That is how this Micron war started as a marketing ploy to sell to the general public. The truth is that micron rating is only a small part of the overall filtration picture, and without considering efficiency, it means nothing. It is a sales tool.





From the Chevron site:

Energy Content:

In general, the processing required to reduce sulfur to 15 ppm also reduces the aromatics content and density of diesel fuel, resulting in a reduction in energy content (BTU/gal).

The expected reduction in energy content is on the order of 1% and may affect fuel mileage.



Oh goodie I can't wait.

IS the low sulfur considered any under 500 whatevers per a gallon or less?



Cause I just filled p today in MO at Shell - and the pump had a sulfur warning on it...

Yep, it must be in Missouri because I also filled up (in Columbia) and noticed the warning on the pump.
