My understanding was that when RLI went from the Bio-Syn to Bio-SynXtra formula, they increased the antimony.

Most DI engine with fuel dilution tend to thin the oil but this seemed to take it very well!
Because bio-based esters are not derived from petroleum feedstocks, they are essentially impervious to fuel dilution. That's what makes these oils ideal for direct injection engines.
Based on Terry Dyson's recommendations, I've switched to the RLI 5w30 HD Low Ash for the Cadillac. Overall, he said the 0w30 did well, but the 5w30 HD is basically the same formulation he worked on with RLI many years ago in 5w40 viscosity to take care of the fuel dilution issues with the Audi direct injection engines.
