ok i want a good high performance oil....im thinking about amsoil or royal purple...my friends dad a hot rod guy whos been in the game for a while claims that amsoil has the highest flash temp and is the best oil...what ever that really means and my other friends uncle has a 7 sec drag car and he uses royal purple...he also said that he blew a motor running on redline synthetic so i doubt im gonna use that...oh yea this is for a b18c...i want the best...im kinda leaning towards the royal purple...

 

most people here use Mobil 1 Tri-Synthetic oil....... it works very well...... as for royal purple, my brother used it before and I don't know how different it was, i didn't see a difference.... so i just used mobil 1 becuase it's tried and true

 

my 2 cents:

i was a firm believer in synthetics for a couple years... i always used mobil1 pure synthetic with a mobil1 or pure1 high dollar filter $6-10

now i believe that changing it more frequently is more important, so i use castrol gtx oil with a cheap puralator filter and change the oil every 1500-2000 miles

before... $4.29qt + $6filter = $28
now ... $1.39qt + $3filter = $10

just my 2 cents
