Hi , i have been reading about millers oil and hi have read a lot of people are using Millers Oils CRX 75w-90 NT but reading about this i have found this diferences about 2016 and 2017 version on this oil the 2016 version uses a grey can and the 2017 uses black can with yellow letters.

So people who are using Millers Oils CRX 75w-90 NT on our f40 gear box are using 2016 o 2017 versión?
