8,500 mile OCI on the RLI. All fuel was bio-blend either commercial B2-B5 in PA and NJ or splash blended by me to B1. FPPlus additive used at each refuel dosed at 1oz/5gallons.
I sampled this as a raw data report without comment by Dyson. My engine is still wearing in. I don't know how much wear figures are linear from the 5K sample to the 8.5K sample, but if they are iron seems to be wearing at same rate and aluminum trending slightly down. Copper is an additive in the oil as shown in the green VOA reference line in the 5K image at the bottom of this post. I'm very pleased soot is zero as that was a goal of using this oil. I don't know where the potassium is coming from. I have no apparent cooling loss. The factory fill contained potassium and perhaps the Bio-syn is cleaning that up. Something to watch.
I refilled with the same oil and will test again at 5K.
