Forgive me if this has already been discussed to any great degree - I couldn't find much on it.
In looking at the Lubrizol relative performance comparison tool, the VW 504/507 specification is equal to or better than the 502/505 specification in every area. It exceeds 502/505 in wear, sludge and piston deposits as well as fuel economy and after treatment compatibility.
I was under the impression that the 504/507 spec was a low SAPS specification. All of the 504/507 oils seem to be 30 weights as opposed to mostly 40 weights in the 502/505 category so I guess fuel economy may also be a goal.
If the Lubrizol tool is to be believed, a 504/507 approved oil would be a better choice for most if not all engines, unless a long drain interval is desired?
Which VW vehicles specify 504/507? The EA888 turbo engine specifies 502/505. Why not 504/507? Why would the EA888 2.0 turbo specify 502/505 when 504/507 offers better wear, sludge and piston deposits?
Please educate me on this.
