Too see chart, click here
Base green color samples are random UOAs waiting for a follow up.
Other "like" color groupings are samples taken from the same engine.
Some of you will notice your UOA is included, as I have snatched a few UOAs from Team Shelby forums. If you have a UOA on your 5.4L Shelby engine that isn't on the list, please post it here for all to see, and I will update this picture with your information.
The poll is to get an idea what everyone is using in their Shelby for engine lubrication. If you chose the "other" option.....please post what you are using in your engine. If anyone needs to know where to get oil testing, visit one of the website links below. Please, if you have your oil tested with Blackstone....opt for the extra $10.00 to have TBN tested. OAI provides TBN testing included with the price. OAI also tests for oxidation (Blackstone does not). Both labs will yield very close consistent results.
Blackstone - will cost $25.00 for basic test, $35.00 with TBN, plus the cost of shipping ($1.90 USPS)
OAI testing kits UPS prepaid - will cost $32.20 - Amsoil preferred customers get this test for $25.95
I'm currently testing the performance of Amsoil 10W-30 in my engine, results to come soon.
