Good to know, maybe I’ll just stop the Schaeffers Carbon Treat/Diesel Treat for a while then and keep using the EDT.

Another question I have for you guys, I noticed reading through the forums here that a guy attributed some higher Iron levels to an additive he was running in his fuel, do you happen to know what additives have been mentioned that might contain Iron? I’ve ran a lot of Schaeffers Carbon Treat and...

Is 18ppm of iron really considered high in 8,100mi? If that’s sheared out at 8,100 miles, the Motorcraft that was in my wife’s new Explorer must really be junk with only 5,000mi on that change?

Hey Everyone, Just getting into doing some analysis on my vehicles again and figured I’d post some results to see what everyone thinks. This ones from a 2014 Ford Escape we purchased new and have pretty much ran Schaeffers the entire time other then a few changes here and there in its life when...

Thank You everyone for all your input by the way. I’ve got a lot to learn on analysis, so all knowledge is welcome. I’m not a big “brand” guy so I’ll try just about anything. I was put on to Schaeffers quite sometime ago by a friend that has a trucking company and he had got me in touch with a...

I’ve been using the Ford Motorcraft filter. I bought the truck with 20,000mi on it, so no idea what was used in it then, but after I bought it, I had gotten a couple free oil changes from the Ford Dealer I bought it from so naturally I took them up on those and they used the 10w-30 Motorcraft...

That bad huh? I’ll run this oil change out to 5,000 again and test again. But if that Irons up that high again I’ll probably try something else. This is my first Diesel in a little while, but all my gas engine vehicles I’ve sampled have looked real good using Schaeffers 9000 5w-30’s and 5w-20’s...

It is a F-250 CC 4wd and my camper weighs about 9,500lbs empty so guessing you could figure probably somewhere around 11,000 loaded and heading down the road. Not a lot of crazy hills around WI, but I was in South Dakota/Blackhills last summer with it for a while towing the camper and I know the...

Hello All, Just recently changed oil on my 17’ 6.7L Powerstroke, had 5,200 mi on oil, approx 56,000mi on truck. I would honestly say 85-90% of the 5,200 miles are towing a 5th Wheel Camper around, curious on what you think of the Analysis results? Iron seems a little high compared to the gassers...

Hello everyone, I have a 2017 Ford F250 Powerstroke with the Sterling 10.5” 3:31 e-lock rear, with just about 60,000mi, I would say a good 75% of the miles are towing, either a fifth wheel camper, skid steer and car trailer, or a snowmobile trailer. Looking in the owners manual I see it calls...

I also had this experience with my 08 F-150 that called for 75w-140, I had about 50,000mi on the truck and ordered SG 75w-140 directly from Amsoil, a couple months later it really started making some noise when turning, I then ordered Amsoils diff lock additive and added to it and still could...
