Other than the silicon you mentioned everything seems well organized. Do you know what weight your going to stick with in the future or just change depending on what's on sale?
 
Hello!
Thanks to good results with thinner oils, I'll move to 50-100% ACEA C2 (~ 10 cst @ 100°C) and ACEA C3 (~ 12 cst @ 100°C) 5w-30 mixes to improve mpg.
