Well the 507 spec is the Castrol edge 5 -30 ...so are some on here saying that the 505.01 should be used instead ?
I doubt that anyone who gives it more than a moment's thought would recommend 505.01 over 507.00. Oil has improved out of all recognition over the past 20 years and 507.00 spec oil is definitely the one to go for.
