Once again, fuel dilution seems to be the culprit of oil viscosity breakdown and high iron. From left to right, Esso XD-3 0w40 5K miles, Mobil Delvac 15w40 5K miles, and now Castrol RX 15w40 only 4000 miles. Total mileage on the engine at latest sample about 18,000miles. I changed the oil early on this interval because the turbo vanes were stuck/coked up and the whole turbo unit was changed. Not sure if the turbo issues would contribute to the high fuel, my guess is they didn't. Also it was getting cold here overnight so decided to use Esso XD-3 0w30. I tried checking my dipstick during the intervals for the oil level rising and smelling it for fuel contamination but didn't see/smell anything. From what I've heard, Ford won't investigate a possible leaking injector unless there's a lot more fuel in the oil. I suspect this fuel level might have contributed to the turbo damage too...
Any ideas? If I extended the interval say beyond 5,000 miles, would the fuel contamination number rise accordingly? So at 4K, I'm at 3%, 5K I'm at 4%, 6K miles 5% perhaps?
