I've been trying to figure out which synthetic is really better for years. No clear winners. All the big name brands do well, Valvoline, Amsoil, Mobil 1, Castrol, QuakerS, Pennz, Kendall, all good.
In a vehicle like that, use the Castrol Edge Extended Perf 5w30 and go 1-year, 15,000 miles, but if its severe service, cut it short to around 8 months maximum.
