Hey Yall,
Give me about 3 months and I will post a Royal Purple 5W30 Blackstone Analysis w/TBN.
My 3800 Series II engine has run Royal Purple non-stop for 55,000miles of its 66,000mile existence from the showroom floor. (It had 2 changes the Mobil 1 Formula in 1998 before the introduction of TriSynthetic.
Only this last change due to me visiting Delaware and the extreme cold we are feeling coupled with me not calling Jegs in time required me to have the last change with Mobil 1 SuperSyn. My standard drain is 3-4months and 3500-5000miles no more than that!
I too am fed up with the rather irrational criticism of Royal Purple products. This is no snake oil for crying out loud. Certain companies, as in if you read the AMSOIL cite obscurely knock Moly in RP...then again Moly has been deemed a GREAT thing here.
As demonstrated by GM High Tech Performance magazine in 1999 or 2000 it did make Dyno Proven HP/Torque gains...no deceptive marketing. Of course that is a engine/application specific situation.
