This site provides information, product reviews and test results that are (hopefully!) in the public interest and I wish that was all I needed to say. Unfortunately, the world is not a perfect place, so I have to clarify a number of points here.  As you can imagine, the text here will probably evolve over time as the need arises. 

Its  sad, but in today’s world I have to say that the content you find here is mine, and that you are free to use it or not to use it.  Sadly, there are some who would attempt to do me harm, so I have tell you that I don’t offer any guarantees or warrantees.  There’s also the chance you will find similar content somewhere else (go team go!) but that doesn’t mean I have copied anyone else because I don’t do that. I only present what I have found and discovered  on my own.    See how crazy the world is?  I’m just trying to provide useful information that will help others.  That’s all.  

Except for some product photos that I have lifted from public websites that allow it (in addition to comments posted by others of course), all of the content in this site, including text and photographs, are  my own original works, and Copyrighted by Diesel Specialties, LLC.   I wish I didn’t have to say it, but without written permission from me, you are not authorized to duplicate or republish any portion of any information on this site in any form, as this will defeat my purpose of organizing  material in a way that documents my results and experiences as they occurred.   That doesn’t mean I think I’m the first to publish anything — it just means I’m publishing information when I find it.  I update pages when I learn something new or decide that it should be re-written.  

Good journalistic practice provides for sites to refer back to each other, so please free to summarize what you find here on your own site (using your own words) as long as you link back here.  I will make every effort to do the same.  Additionally I ask that you please give me the opportunity to correct anything on this site that does not follow this guidance.  

By the way — I don’t accept remuneration for any of my work.  that means I write about what I think is cool, not what someone else wants me to write about.  


What Authority or Credentials do I have?

The popular “argument from authority” is fundamentally flawed, so I’ll resist the temptation to describe whatever credentials I have because it  doesn’t matter.   Moreover, my site does not present any information from the standpoint of authority.  If something is true, it is true — no matter who said it.  To that end, my approach is to present information and results, which I hope you find profoundly more useful than lists and steps asserted as if I am some sort of authority. In my view, truth itself is what has authority, not people or credentials, and so the conclusions I reach are based purely on my observations.  That means as I learn more and have more “ah-hah” moments I will update my articles and posts to reflect the latest and best information that I have.    



As much as I would like to provide the content here as a free service, the reality on the ground is that I can’t.  Accordingly, this site may display ads to help offset the hosting, web development, photography and other expenses related to my work on  this site, but I do not profit from this endeavor .   The ads that you may see on this site are provided by third parties, and are intended to be relevant to you. Please understand that the adds you see are unique to you;  I have no control over the ad content itself. 


Products,  Manufacturers, and original works

With the small amount of traffic here, even the ads that I may allow on this site don’t cover my expenses.   My work will continue to be independent, not beholden to any manufacturer, and conducted as objectively as possible.   This approach will preserve my ability to call snake oil and give raspberries!  It will also allow me to continue testing products as I see fit and to report my results exactly as I have experience them.  


I appreciate,  encourage, and will approve thoughtful comments made in good faith and on topic, because this helps to move the truth needle.  My hosting provider (SiteGround) does some things without my involvement, however, so in the spirit of full disclosure, here is what I know so far:

  • The site collects the data shown  the comments form, along with your IP address and browser user agent string to help spam detection.  
  • An anonymized string is created from your email address (a “hash”)  which may be provided to Gravatar to see if you are using that service. The Gravatar service privacy policy is available here: httpss://  After approval of your comment, your profile picture is visible to the public in the context of your comment.



Siteground probably (I just don’t know the answer for certain) utilizes cookies.  The ads that you may see here also probably utilize cookies of some sort, although as of this writing I am not able to describe what they do.  At some point in time I will probably authorize google to place ads on this site, and I’m sure you can imagine what sort of data google is capable of collecting, all of which is out of my control.  

If you leave a comment, I am told that you will be given the opportunity to “opt-in” to saving your name, email address and website in cookies. These are for your convenience, not mine (I don’t harvest cookies myself or use that information) so that you do not have to fill in your details again when you leave another comment. My hosting provider tells me that these cookies will last for one year.

If you visit a login page, this site will set a temporary cookie to determine if your browser accepts cookies. This cookie contains no personal data and is discarded when you close your browser.

When/if you log in, I  understand that the site will set up several cookies designed to save your login information and your screen display choices. If you log out of your account, my understanding is that these login cookies will be removed.

Embedded content from other websites

Articles on this site may include “embedded content”, i.e. videos, images, articles, etc., from other sites, presented within a container on this site.   Embedded content from other websites behaves in the exact same way as if the visitor has visited the other website.

These websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content, including tracking your interaction with the embedded content if you have an account and are logged in to that website.
