  1. Secondo, sent you a PM to assist. Actually, it's for those who would only use what Ford recommends. You are interpreting it as it must be adhered too, which isn't fact. I still wont use it in any GT500 driven on the street or drag strip only. Closed course racing, perhaps. Ford may walk away from the specification. Have you noticed the 2015 GT Performance Package only recommends 5W-20. The previous year Track Pack GT was 5W-50.
  2. Hello fellow Mustang owners. Amsoil finally decided enough Ford vehicles were on the streets and track to formulate a Signature Series lubricant that meets API SN and Ford WSS-M2C931-C requirements. This is a big deal for those who are worried about not having Ford's recommended SAE lubricant in their Mustang. Amsoil Signature Series 5W-50 This is the only known lubricant to carry Ford's recommendation code other than Motorcraft 5W-50. APPLICATIONS AMSOIL Signature Series Synthetic Motor Oil is excellent for use in all types of gasoline-fueled vehicles. It is recommended for all domestic and foreign vehicles requiring any of the listed performance specifications: 5W-50 (AMR): API SN, SM...; Ford WSS-M2C931-C (Mustang) This also means Amsoil's Warranty will now cover your Condor or Trinity engine that is spec'd for 5W-50. Preferred Customers can purchase this formulation for $8.15 per quart or $92.85 per case (12 quarts). Amsoil's EaO11 oil filter is recommended for your application. Looks like we have another new lubricant to test in the GT500 UOA Thread. With Amsoil's desire to produce only the best formulation possible, I'd assume it's more shear resistant than Motorcraft 5W-50. However, only time and testing will tell.
  3. Not a stupid question at all. My 2014 Twin Turbo 5.0 (Armageddon Kit) has Dominator 10W-30 in the sump. Works great, and I change it every 6 months since I only drive the car one day a week. However, I also never drive it in freezing or wet weather. That being said, if you store your car during the winter freezing months, I'd say it's fine to use ATM 10W-30 Signature Series or Dominator RD30. If you drive your car year round, I'd recommend AZO 0W-30. I live in the south, so that allows me to run 10W-30 year round with no concerns. We have 1 month or less of weather in the 20*F range. The remainder of the year is above 32*F and near 100*F in the hottest summer months. Jim C, thank you for this report and your detailed information, as I overlooked it. I'm not getting emails about thread updates. I will get this added right now.
  4. Chart has grown to 89 entries so far, lots of trends with same engine follow ups on the chart.
  5. This is what a clean intercooler looks like. This car only had 1,000 miles on it when I removed the supercharger. You can already see buildup with Motorcraft 5W-50. Pic #1 This is what your intercooler looks like after 30,000 miles with Motorcraft 5W-50. Pic #2 This is what it looked like after cleaning. You can still see nasty in the corners I wasn't finished with yet. Pic #3 This was my GT500, after 10,000 miles of Amsoil 10W-30/40 and 1,500 miles of Motorcraft 5W-50. So much less build up. Which would you rather have? Pic #4
  6. Actually, no....the formulation shears because it's a cheap base oil using cheap VII (viscosity improving polymers). When heated, the polymers expand to retain a higher 50 grade viscosity than the native base oil, which is a 30 grade. The bad news is, when the polymers wear (shear), rapidly, you are left with the native base oil. MC 5W-50 actually specs as a 20W-50 above 32*F. It doesn't flow in freezing temps as the "5W" suggests. You can thank cheap base oil for that. It has a NOACK Volatility of 13%, and that is causing massive vapor oil consumption back into the intake, coating the intercooler under the supercharger. I've seen many of them, and it's not pretty. Had to clean more than one. I'd take a lower viscosity lubricant in the 30-40 grade range, depending on use. A lubricant with very low NOACK Volatility (less than 6%) to significantly reduce vapor contamination on the intercooler. That's more than a 50% reduction. It was also proven that lower NOACK base oils would last longer (TBN), because the additive package was not being lost to vaporization as rapidly. I can go on and on, but for argument sake.....MC 5W-50 wasn't chosen because it was the best lubricant for the engine. It was chosen because Ford has a monopoly on the recommendation. $$$$$$ Any honest chemical engineer or tribologist will tell you that, face to face.
  7. You mean, you would pay big bucks to hear engineers say..... "We asked the bean counters to reconsider, but it was a money game for them." Welcome to corporate America pal.
  8. Red Line 5W-50 is a terrible option in this engine. Most UOA results showed elevated levels of lead ppm, likely due to the cars being used on the street and the formulation not shearing outside of its 50 weight grade, un-like Motorcraft 5W-50 shearing. It's good that MC does shear, as a true 50 grade lubricant isn't required in this engine. Michael Rauscher @ L&M engines reports all 5.4L and 5.8L engines he assembles and test have too high oil pressure on break in using 30 grade lubricants. This supports my discoveries as well, using an electronic oil pressure sensor during testing of different viscosity lubricants for use on the street. He doesn't support 50 grade lubricants in a GT500 engine either. Guess I better call him, saying he is making a huge mistake. You better feel fortunate Motorcraft 5W-50 does shear. If it didn't, you'd have elevated lead ppm wear in your UOA's as well. It's to viscous for street use. The difference between you and I. I test, research, and prove what I preach. You type what you have heard, or what Ford says, not what you have personally witnessed with your own eyes, with your own testing, or what others have proven. Here is a challenge for you, my good sir. Find one thread, just one....any GT500 engine that has failed and was lubricant related. Bet you can't! Self proclaimed? You mean the guy/members who actually did the foot work, while you and Secondo type your opinions, no facts, no documented proof on any statements you make here? Just like the Liberal media, "We won't discuss the facts people, because it doesn't align with our agenda." You really think the API SM to SN transition made a significant impact in the formulation? Hardly! Results of both lubricants were the same.
  9. This topic has been beat to death. One vital discovery, Motorcraft 5W-50 is junk in comparison, rapidly shearing to a lighter grade lubricant. Within 1,500 miles, it's a light 40 grade. Long before it's used up, it's a heavy 30 grade lubricant. UOA thread 5W-50
  10. Chart in post #1 updated with latest samples. Technically....no one does. Motorcraft 5W-50 is the only lubricant in the world that carries Ford's certification for their 5W-50 specification. Considering the Magnuson-Moss act, doesn't this mean Ford has to provide their lubricant for free if they want to void your engine warranty for using any other engine lubricant?
  11. Spreadsheet in post #1 has been updated with every UOA to date. A lot of good information to be found there. Amsoil still ranks #1. Need samples of Royal Purple HPS and XPR for comparison, but no one is running it in their GT500 that I know of. Any takers?
  12. Updated the excel spreadsheet in post #1. I would like to thank EVERYONE who has contributed so far, and Happy Thanksgiving to you all.
  13. First post has been updated with used samples from Schaeffer's 5W-50, Motul 300V 10W-40, Roush 5W-50, and more samples of Amsoil AMO 10W-40.
  14. UOA chart in first post has been updated with many new UOA's and same engine groupings moved closer to each other for easier reading.
  15. This is an authentic signature by Carroll Shelby in 2009. Notice it only has two slashes under his name. Looks like the "third slash" will be the unique computer signature.
