That being said I run royal purple with Honda filter, or Mobil 1 snth with Honda filter. I would never run pennz or valvoline...ever.
what specifically is wrong with pennz or valvoline?
its pretty well known in the evo community, that given the same oil rating and weight, that some oil brands make more power during dyno testing...same car same day same hour etc. dont actually have any hard data at work, but a good evo friend has his own shop/dyno, and he's seen it all.
it was kind of disappointing to see Redline and Mobil 1 fare pretty low compared to other brands. However, Royal Purple and Eneos rate at the top as far as hp and tq output goes.
as far as actual protection and lubricity factors go, thats another ball game..
