Does it cause fuel dilution of the oil, damage the injectors, is it corrosive, what? Not disagreeing, just hoping for more info.
Here is how PS engineering replied to my email concerning this topic
(PS Advisor) is power services support persons answer to my statement or question.
Statement:As usual misinformation is the norm on most website
forums intending to educate.
Statement:It has been suggested that adding to much PS Diesel supplement to the fuel will cause adverse effects
due to diluting the engine oil and causing internal damage to the engine .
PS Advisor: There is some truth to this however it only occurs at very high over treatment rates and is a topic to discuss over a cup of coffee and is more theory than an actual everyday problem. If you didn't ever change the oil then over time enough blow by could occur and then some adverse changes to the oil could occur. Again we are dealing with what will not typically happen and is over hyped on the internet by those who want to look important or knowledgeable but really has little to no practical application.
If you add too much antigel product to your fuel you can, in some fuels, get less antigel protection. This is called a reversion. You can safely use a single or double treat rate of our antigel products, Arctic Express or Diesel Fuel Supplement (DFS), and this will not cause any adverse affect to the engine or oil.
You can triple treat but usually the extra benefits are not worth the extra costs. If you are using Biodiesel then sometimes you have to triple treat to get
the max benefits and protection. If you 5 times treat then you could get too much antigel into the fuel and some black smoke may occur. This would be
costly to do and most people who do this do it by accident. At 5X the treat rate the blow by that gets into the oil crankcase might have a thickening affect on the
oil but not likely to cause a real problem. Highly unlikely to cause any engine damage and is more theory than actual fact.
Question:The subject comes up due to the fact that many diesel vehicles and off road equipment have small fuel tanks that require a bit of math to adjust the recommended 32 oz to 100 gallon recommended ratio formula.
PS Advisor: If you are using the quart bottle then use 1 ounce to each 3 gallons of fuel. This will help measure out additive for small amounts of fuel.
Question: I own an older diesel compact tractor that I mix PS Supplement with the fuel due to the low sulpher (Most likely Ultra Low Sulfur Fuel) fuel that is available at the pump.The tractor has a 9 gallon tank. I regular mix 4 oz of Supplement to every tank simply because
I have a recycled 4 oz container available which I fill to the full line at the top which makes it easy to do since there is no measuring involved. This is only slightly more then the suggested ratio
The question I have is, if I increased the amount to more then 4 oz
to help with lubrication and the cold starting we encounter in N.E. Ohio
do I risk damage or accelerated wear, to any componet of the engine or fuel system?
PS Advisor: No, absolutely not. For 9 gallons a single treat rate would be 3 ounces
of DFS or if you want to max out your protection then you can add 6 ounces of DFS and not have any adverse affects to the engine or the oil. We suggest
that you do not exceed a double treat rate but if you did triple treat this would not cause any damage or problems to the motor or oil.
Question:Is there a ratio where a particularly excess amount of PS Supplement added to the fuel would be damaging?
PS Advisor :Yes, there is a point where you could affect the
flash point of the fuel but to get to this rate you would have to go crazy to add that much. We have conducted testing at 5 times the treat rate and the only problems encountered are that the engine will start to smoke, too much detergents at this level could interfere with cleaning injectors, antigel levels at this treat rate can end up giving you less antigel protection due to Cold Filter Plugging Point reversion. It is possible to adversely affect the flash point of some fuels but not likely for most fuels (Flash Point of fuels vary so some diesel fuels have higher flash points than others). If you change the flash point outside the ASTM D975 standard of the fuel then it is possible to adversely affect the engine.
Question:The claims are that the extra additive doesnt burn "off" completely and then mixes with the oil and causes internal engine damage.
PS: Well, again this can happen at very high levels and way above the recommended treat rates. This is just some exercise in theory and really does not apply to the real world since most people are not going to over treat at a level to cause this type of problem.

Apparently there was a lot of water in that VW dealer fuel.
