Amsoil Signature Series 5W-30 Synthetic Motor Oil W/ Amsoil Filter Goes in 2014 Cadillac CTS V Coupe and the 2013 Super Snake gets MotorCraft Full Synthetic 5W50 W/ Ford Racing oil filter. Just started using FilterMag magnets with both as well.
Move the Super Snake to Amsoil Signature Series, @Vinnie_B. Your engine will thank you.Amsoil Signature Series 5W-30 Synthetic Motor Oil W/ Amsoil Filter Goes in 2014 Cadillac CTS V Coupe and the 2013 Super Snake gets MotorCraft Full Synthetic 5W50 W/ Ford Racing oil filter.

Hey @Norton No doubt Amsoil is a better oil! Once I get done with my left over stock of Motorcraft Im going to switch over the SS to Amsoil as well. I know you dont use 5W50 in amsoil. What weight oil are you using? Why? Can you post the amsoil link of the oil your using in the Shelby GT500 so I can check it out. I'd appreciate it!Move the Super Snake to Amsoil Signature Series, @Vinnie_B. Your engine will thank you.
I run Amsoil Signature Series 0W-40 (AZFQT), @Vinnie_B. As you know, Amsoil base stocks and additive packages are better than most alternatives, including Motorcraft, so that part of the decision was easy. I chose the viscosity after reviewing oil analyses, with an eye toward sheared viscosities of "used" oils. The sheared viscosity of AZFQT most closely approximated that of Motorcraft 5W-50, recommended by Ford's SVT. IMO, that gives my engine the best of both worlds.Hey @Norton No doubt Amsoil is a better oil! Once I get done with my left over stock of Motorcraft Im going to switch over the SS to Amsoil as well.

Thats a very interesting analysis and makes total sense. I appreciate the recommendation and the links. Thank you for sharing this info...I run Amsoil Signature Series 0W-40 (AZFQT), @Vinnie_B.

Motorcraft 5w50 is basically a 40w oil. I talked to SVT engineers about this years ago, it was a marketing decision. For the longest time only Motorcraft offered oil in that spec.
Listen guys......all this talk about oil viscosity, 40 weight, sheared viscosities got my head spinning.......Im a electrical terd......I mean nerd....... what F'in oil is the best for my 5.8 SS dammit......lmaoI run Amsoil Signature Series 0W-40 (AZFQT), @Vinnie_B.

Opinions are likely to be all over the place, @Vinnie_B. For my operating environment, that includes some driving in (chilly) spring and fall mornings, I believe Amsoil Signature Series 0W-40 (AZFQT) is the best option. 0-weight provides the best/quickest flow at startup, while 40-weight provides good (expected) viscosity at operating temp.Listen guys......all this talk about oil viscosity, 40 weight, sheared viscosities got my head spinning.......Im a electrical terd......I mean nerd....... what F'in oil is the best for my 5.8 SS dammit......lmao
Lol..... I'm just jk'in around. Yea I was looking at some viscosity charts and according to them it matches exactly the way you just explained it....thanks for confirming what I interpreted from the charts thou. Thanks brother.... I'm thinkin due to the weather here in MI and me not driving in cold temps at all 5W-50 Amsoil will be the way for me too go!Opinions are likely to be all over the place, @Vinnie_B.

If you generally operate in high temp environments, Amsoil Signature Series 5W-50 (AMRQT) may be a better option.
So....... I finally found some time to do a oil change on my 2013 SS and I could not believe the results so far......unbeliveable difference. I changed oil from Motorcraft 5W-50 to Amsoil signature series 5W-50. I started the car and after 5 minutes or so it was very noticeable that the engine sounded much quieter and acually looked as if the motor was just idleing much smoother than before the oil change. Im in awe of the difference between the 2 oils and the difference it has made on the motor mechanically......unbelieveable. Im wondering if I see any difference in some data log info such as heat and any minor performance gain. Anyway's...... I couldnt thank you enough @Norton for the recommendation of Amsoil signature series oil. I still just cannot believe the difference.......wow!!Opinions are likely to be all over the place, @Vinnie_B.

I'm happy to hear that, @Vinnie_B!So....... I finally found some time to do a oil change on my 2013 SS and I could not believe the results so far......unbeliveable difference.

Ive heard good things about Pennzoil Ultra Platinum. But have never personally tried it yet in a vehicle. I just started using Amsoil SS 5W-50 in the 2013 GT500 SS that was recommended by @Norton. I switch from Motorcraft. The results are remarkable and that 5.8 mod motor fell in love with it. The motor just runs so much smoother and cooler. Im still amazed and didnt expect those kind of results!! Thanks for sharing the video @gimmie11s.............The best "off the shelf" oil you can buy for a performance vehicle is Pennzoil Ultra Platinum.
The best "period" oil you can buy is Amsoil -- but you WILL PAY for it.
That said, the difference between Amsoil and Pennz UP is not large enough for me to make the switch and spend the extra money. Im a Pennzoil guy.
Check out the bracket this guy created for ALL of the major oil offerings. Pretty damn in depth testing here.... Amazon, Mobil 1, Lucas, Redline, Royal Purple, pretty much ALL of them were tested.

Im a believer now!! But honestly........no way did I expected to see, hear results from this oil in that manner. Im just amazed!Amsoil is the best.... no doubt about that. They make a great product.
To each their own. Everyone will claim their stuff is the best. And everyone who uses it will say the same thing. The best advice i give people when looking into oils is to ask questions, find out the way they make the oils, like do they batch blend?The best "off the shelf" oil you can buy for a performance vehicle is Pennzoil Ultra Platinum.
