5w20 is very new & scarce, but will start increasing in demand soon. Ford are developing it for use across their new cars, so that will stimulate demand soon enough. We haven't got it yet, but I'm already onto trying to sort some as soon as I can. As for the 10w60, we stock Castrol Edge in that grade. It's not cheap, but Castrol isn't these days. Primarily for Beemer M-series and Alfa Twinspark motors from memory, but also probably useful if you're thrashing the nuts off a car on a track day. Next closest would be Mobil 1 Motorsport, which is a 15w50. Both should hold their viscosity well.
