I can't search so i don't know if this has been posted before. Saw a local shop advertising Synpower to be 4x better than M1 and found this. Seems to be a very bold statement if untrue?

actually my local shop... Zimmerman Bros which has 3 salt flat records and 3 nhra national championships. wont warranty their engines with anything but mobile or royal purple...and they have ran tests on majority of all oils those two are the only ones they trust. so i wouldnt think its 5 times better lol
