Sample time is 175 hours, 5700 miles. Filter was a Baldwin B7379. A lot of towing through the mountains with high RPM engine braking, also mixed in with several short trips where engine barely gets up to temp. This truck also has a good amount of idle time (wife and kids like the ac while running errands). Iron might be a little high at 2.6-2.7PPM/1000 miles but given the service it sees I’m not surprised. The silicon is likely from recent upper oil pan resealed, they used a copious amount of silicone by the look of it (excessive amounts hanging outside the pan). The sample was taken on a cold engine, mid way through the drain. Not sure if that has anything to do with fuel dilution or not, but it doesn’t seem to be hurting anything. I use optilube XDP and hot shots LX4 additives every fill up for fueI, so it’s nice to see soot nice and low at 0.3%. I refilled with HPL 5w40 premium cold weather and also a dual bypass oil filtration system with amsoil EAO26 and EaBP100 filters. I hope to get 20K miles out of this new setup, I’m just concerned about my winter short trips are really going to hurt the fuel dilution, it will likely take me 2 winters to get to that mileage There’s no way around it unfortunately.
Does anyone feel the viscosity is where it should be given the fuel dilution/oxidation? @dnewton3
