Who's knows what they will say, because they don't seem to know or want to know what's going on, my situation was way worse before the HPFP change and that was all their oil changes!
Got my results back from Blackstone,not looking too good. Fuel dilution up quite a bit but last test was done with less than 400 miles on the oil. This test almost 3000 on the oil, although the level on the dipstick was also at the top hole! Gonna change the oil and see what happens this time. I...
If your going up to the top hole from the top of the hash mark in a few hundred miles I really don't think 5 or 6 less ounces of oil is going to matter. Just going to bring the level up more!
Yeah about an eighth of an inch over hash marks if the 6.2 quarts are added!! I do not worry about the .2 part having fuel dilution, I put in 6 quarts.
I think it stands to reason after letting the truck sit overnight all the oil has drained down to the pan and cooled that's when you would get your most accurate reading. Every vehicle I've owned that's the way I checked it for an accurate reading!!
Mine was that bad before the HPFP change but that improved it quite a bit. But did not fix the problem, I've been trying to improve it further. It seems like the change to 5/40 has helped also,now I've been staying right around the top hole. Before the 5/40 oil change I was going about a quarter...
That's what's strange about this whole thing. Some it shows up from brand new and for some it takes 10 to 15 thousand miles to show up. Mine didn't start till between 8 and 9 thousand miles!
They claimed they did all those tests on mine and it passed them all! Before that they did change the HPFP, that helped it was really bad at that point!
I posted a link on that most modern day synthetics can handle up to 4% fuel dilution. I've even read some saying it could be as high as 7%, but the article also stated just in testing not recommended !
