Pretty simple. Then the problems begin. I come from a family with an extensive automotive background. It is not as simple as you think.

Again, I'd rather use RL w/o the Starbusrt than Amsoil w/o the Starburst. Why don't you get that?

Once again, call FMC or Chrysler and ask them if you can use SSO 0W30 in a new car they spec 5W20 for. They will tell you NO.

So AD, I'll call Ford tomorrow and ask them if using AMSOIL SSO 0w30 will void the warranty for this vehicle:
2010 FORD MUSTANG 4.6L 8-cyl Engine Code [H]
LUBRICANTS & FLUIDS:
Engine Oil
Grade 1......API*[1]
100% Synthetic 0W-20 Motor Oil (ASMQT)
XL 5W-20 Synthetic Motor Oil (XLMQT)
Signature Series 0W-30 100% Synthetic Motor Oil (SSOQT)
All TEMPS......5W-20
[1] Manufacturer recommends motor oil that is formulated to meet
Ford specification WSS-M2C930-A.

Is this correct?
