Thanks for the infoI have a friend who builds engines. He took a newly built motor on a dyno and ran brand new oil and wrote down HP, TQ, MPG and then tore the motor down to inspect for wear. Replaced all worn parts and did this again and again each time switching oil types and brands.
The top ones, best:
1st Brad Penn
2nd Royal Purple tied with Mobil 1 full Syn
Last on the list, worst:
Castrol
I run Mobil 1 Full syn cause I can get it everywhere.
Take this info how you like and run what you believe in.
