My NAPA kit said half way through the drain. Snoking
Yes that is true. Very best way to sample is to remove the 1/8" pipe plug on the top of the fuel filter housing and screw in a fitting that has a barbed hose end then slip over a rubber hose long enough to put into oil fill hole. Start engine and let it run for a couple minutes to clean out any impurities of the hose. Then pull hose and place into sample bottle until its full stick hose back in hole and shut off engine then replace plug.
You might just be happy to know that I changed the oil, oil filter, air filter, and both fuel filters yesterday----AND I ACTUALLY REMEMBERED TO SAVE SOME FOR A SAMPLE!!!That would be interesting to see your results with you working your truck and having that many miles.
Great Idea!!! Then I should buy stock on AMZ/OIL!
Here's the report: 4% fuel dilution but no signs of it affecting wear. SuperTec at 10 bucks per gallon seems to be doing just fine.
I'll go ahead and change oil over the weekend. I have another Stratapore filter I'll use; I'll do another sampling after 5K miles to have a good baseline. I'll then try one of those fancy Venturi filters see what that does to wear.
What year is your truck. Fill in your signature it will help.
I'll do that. For the time being is a 2012 2500 all stock.

I'll share something I learned about fuel dilution.
Although fuel dilution is normally associated with reduction in oil viscosity, that is not really the biger issue.
The bigger issue is the degradation of the additive package which is particularly severe with the biodiesel blends.
A lot of the additive packages such as friction modifier and anti-wear additives are made up of polar molecules. Turns out that biodiesel, namely the fatty acid methyl esters (FAME) is also comprised of polar molecules. Petrodiesel as well as renewable diesel (hydrotreated vegetable oil) are generally non polar.
As a result when biodiesel comes into contact with the oil it interfere with the additive package.
What makes the matter worse is that biodiesel has a higher distillation temperature than petrodiesel and HVO. As a result when the post injection takes place the portion that doesn't evaporates and wets the cylinder walls has a higher concentration of biodiesel.
