What oil do you use?

jerflash

royal purple 20w50 or mobile one 15w50. reason for the thick oil is the bearing tolorences that the motor was built with. nitrous motor

I would take a look at the viscosity values and other specs for Red Line or Amsoil in the 20w050. I think you will find either of those offer more protection than the Royal Purple or Mobil 1. In any event, I would be looking for a new lubricant.

ya also i was thinking about it and i think the cold startups in the winter could also be a cause. that thick of oil the cold weather cant be good.

i used to run amsoil all the time and my dad used to be a dealer but not anymore. i think i may try something different and maybe try some 10w40 and see how my pressure look after i get everything back together
