Official Mustang Boss 302 UOA thread
We have been doing this in the GT500 section for quite a while now, and I'm seeking interest in the Coyote/Roadrunner areas of the forum. For those who do not know, it's a Used Oil Analysis thread to show trends in wear patterns to help owners determine what is normal, and what isn't. This is a great way to monitor your engine's wear patterns over time, and to show you how well the oil you choose is performing in your engine.
Here is the Excel spreadsheet I have created which is Roadrunner exclusive.
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
Latest Amsoil recommendations as of July 2015
This recommendation list will cover all seasons for your car, from the harshest winter days, to the hottest summer days. The best part is the oil only has to be changed once a year or 15,000 miles, whichever occur first. Amsoil AZF 0W-40 (Challenger Hellcat and Nissan GTR) and AMR 5W-50 (Ford Mustang) are two new formulations created for powerful street cars.
8 quart fill – GT
8.5 quart fill – Boss 302 and Track Pack GT
Amsoil ALM 5W-20 – If your engine is 100% internally stock in Naturally Aspirated form, regardless of external simple bolt on mods, driven daily in all climates, use this. *Mustang GT only* previously, the old list recommended formulations in the 0W-30 to 10W-30 range for this engine. However, after testing in my personal 2014 Mustang GT with a stock engine, 5W-20 Signature Series is a contender. Using previous recommendations is OK, but will now use AZF 0W-40 as the blanket for most application requirements beyond 5W-20 for simplicity.
Amsoil AZF 0W-40 - If you have a Boss 302 or Track Pack GT and you do not attend HPDE events, use this. Some people ask me if it’s OK to use this at the HPDE. If you plan to attend one event a year and are not driving the car to the edge of cooling limits, it’s acceptable. Schedule the annual oil change to happen right before the event to insure the lubricant is fresh. However, if you are an experienced HPDE track person, 5W-50 may be better suited for you. See the recommendation for 5W-50.
Amsoil AMR 5W-50 - If your street car has a single/twin turbo or supercharger making a lot of power on pump gas or with advanced timing using E85 (or) If you have a Boss 302 or Track Pack GT, and you HPDE or race your car in competition for extended sessions….use this. *Not optimal for short trip, grocery getting, daily driven street duties. If you have a turbo or supercharged car that is driven daily, isn’t raced frequently, used on the streets for occasional wide open throttle bursts, Amsoil AZF 0W-40 is a better choice.*
Amsoil EaO17 - This oil filter outperforms any filter on the market for the Coyote/Roadrunner. Royal Purple is the same filter, part # 20-500.
Amsoil Synchromesh - requires 3 quarts. Use this if you road race your car, or you are experiencing poor shifting.
If you have the Auto 6 speed, this stuff will survive the worst torture.
Amsoil LV Synthetic ATF - 12 quart total fill
and for the rear differential
Amsoil 75W-140 - requires 3 quarts
Don't forget the friction modifier
Amsoil Slip Lock - use all four ounces
*Boss 302 and Track Pack GT owners. If you have the Torsen differential in your car, do not use friction modifier.*
Amsoil Fuel Stabilizer - Use 1 ounce per 2.5 gallons of gasoline when storing your car in the winter.
Bottle Hand Pump - makes pumping new fluid into the transmission and rear differential very easy.
UOA testing kit - we have dedicated UOA threads to compare everyone's reports.

Last thing, do NOT pay retail for Amsoil...EVER! This is how to buy all Amsoil products at wholesale cost (saves 25% off retail).
