What would be your take (mm,mm opinion) on this.
An earlier and even mid 90's car would say in the owner's manual the proverbial 3,000 mile severe service, or 7500 miles otherwise.
I wonder what the newer(est) owner's manuals are saying.
Since we have the new SL classification, and they are tested to "supposedly" go the longest distance of what the individual car makers say in the owner's manual; isn't this kind of like Danny Devito standing next to Shaquile Oneal and both buying the same underwears with the label "Same size fits all."???
Will those additives go the distance for all???
