Maxima 927 or Klotz Benol are both great.

actually both of those will kill your engine......... castor oil leaves extremely hard deposits that will jam the seals into the rotor, if they jam up while in boost then kiss your engine goodbye, even outside of boost it isn't a pleasant death.

avoid any castor oils, if you really feel like running a castor oil use a completely synthetic version like redline or AMSoil.

if you've been running castor oil, for the love of god STOP!

Any proof insightful? I highly doubt that's the premix causing the issue.

I've been using it for 5 years with no issues. Car makes over 700rwhp and drives several thousand miles a year. I've inspected motor internally and I have zero issues with build-up.

Klotz Benol and Maxima 927 are both synthetic.

1 engine i tore apart with 927 had stuck seals and a punched rotor face.

another engine i pulled apart that ran klotz benol had pretty much identical damage except several punched in rotor faces.

both engines had warped seals that decided to barely run after dyno sessions. the carbon couldn't even be scraped off by hand, it was baked on in hard.


the only picture i could get you is of the dented rotor that i turned into a clock display. it's your car, do what you want with it.
