Goal - To figure out which grade oil would be best to run for my application.
Background - As we all know, Ford spec'd the majority of Mustangs to 5W20 and has been much debate due to high temps of the 5.0, and we know that the Boss 302 (forged internals) & the supercharged GT500 spec 5W50.
Hardware:
Enviornment:
NOTE: I typically change out oil once every 2-6 weeks, depending on use, so swapping oils types between winter, summer and track is common for me. I don't mind changing oil grades depending on the application.
========================================
I've called around and asked around and here is the information I gathered:
Amsoil - ZROD 10W30 would be the best bet. For use on/off track. The additives here are perfect for my need, from what it looks like.
AllFordMustangs.com forum - two other guys running a very similar engine build (not completed yet) say they will be running 10W30 (Texas) & the other 5W20, 5W30 or 10W30.
I've gone through the Oil University read through and the 5W30, 10W30 or 5W40 seems like the most logical choice, but I really would like some knowledgeable feedback since I am fairly new to this.
A big Amsoil fan here. Prefer to run nothing but a fully synthetic filter & fully synthetic stock oil. Previously been running Dominator 5W20 before this build because the RP just didn't stack up to the high heats my car goes through with the road course hot lapping days (this engine likes it's revvs).
Thanks for reading guys!

Hardware:
- Machined 3.7L OE block (build 1 in 2011) w/tigher tolerances
- Manley forged pistons & rods, clevite racing bearings, total seal rings & chromoly wrist pins
- OE forged crank, ground, balanced & cryo'd
- Heads honed to match block
- Procharger P1SC1 supercharger kit for the 3.7L
Enviornment:
- Track days (road course)
- Summer street (temps reaching over 100F, performance driven, higher RPMs than stock)
- Winter street (temps reaching -50F, lightly driven - lower RPMs)
