I can't find any stats on the bardahl from their website.
Mobils is here

How can one compare these oils if Bardahl aint publishing the stats. "My engine didn't blow up?? Must be good oil.. so".
All these oils have to conform to standards, its seems that all the fuss is wrapped up brand speak! "Kinematic viscosity is graded by measuring the time it takes for a standard amount of oil to flow through a standard orifice". Are these oils not rated the same in terms of flow? Or is it that secret ingredient mobil / or bardahl put into there oils that makes engines unbreakable.
Alot of lads seem to swear by mobil and the nascar lads endorse it (all money/ brand centric aswell however). And from this thread, there has been a number of oil brand / types mentioned.. some of which people say do the job fine in their race cars (what does oil do!! Loobs shits

).. there may be more/ less wear on internals with some of these oils.. I don't think anybody can prove this right or wrong. I don't think anyone can prove that the brand of oil they put in was the root cause of there engine dying, unless people have experiences.. but i'd say the cause was something unrelated to the type of oil!
I'm no oil expert, but just my piece.
