Right now I'm running Castroil 10w-30. I plan to boost my D16Z6 after I finish my auto to manual swap.
So, my two questions are 1) Should I switch to synthetic or stay conventional and change weights? 2) What tranny oil is gonna be my best bet?

BTW 170k on the motor.

 

Okay sounds good to me. thnx

 

I'll just stay 10w30 and run honda MTF. thnx.

Saved my cams/rockers from consuming themselves... SMOKED Redline and Mobil 1 as well.... Just happen to have a case at my house as Ive came to believe... Results dont lie, its an independant test... AND THE RESULTS OF THE ---- ARE AMAZING!!!

650-7.50 a qt, cheap insurance.... I change mine every 1500-200 at the MOST, and it is neve beaten dead by any means.

 

Rotella T has been proven time and time again to be one of the best if not the best conventional oil. It's regarded as the best break-in oil by everyone, including old school hot rodders. If I were limiting myself to conventional there would be no question in my mind about it.

 

Rocken the albersons brand .99 cent 10w-30.......lol I dont give a ---- about my transmission. They are like oil filters I just change them every 3000 miles.
