Many street only Boss 302 engines have opted for a true synthetic 10W-30.
Curious where you're getting this info. I've owned my Boss since March 2011 and I know of no other owners running 10W-30. Thanks.

Unleashed Beast, you have done some awesome work in dissecting oil specs which otherwise are a black art. I was hoping to make my own conclusion by reading every single post, but I thought it would be better to get your opinion.
I live in Toronto and last year drove my 13' Boss from May to December. I dont plan to drive it until December again, and will probably drive until September-October this year. I dont really track the car, will hopefully have 1-3 track days this summer. Other than that I DD the car. I drive 80 km everyday, and have a 70/30 mix of highway/street driving. Daily driving is relaxed, and im usually in light traffic all the time. I like to do a few pulls here and there. Car is also stock, with upgrades planned for intake and exhaust.
What do you think would be the best option in my situation?

Amsoil Syncromesh - requires 3 quarts
Troy,
I have a few questions:
Ref the MT82 oil, the Amsoil Catalog does not list any fluid as you suggest. Any idea why?
Also, I really get it from this thread about the MC 5w-50 oil but I just changed it & have another 8.5QTS in reserve for another change, so be it.
Do you know who manufactures it? When I worked for Ford many moons ago, it was Exxon.
I understand the FL1A filters are Purolator Pure-One's..... Do you know who makes the FL500S?
Thanks for all your research & info...........
AMSOIL Synthetic Racing Motor Oil
Would the racing version of amsoil (Dominator 10w-30) be a good choice for drag racing applications in high heat index areas in Texas (100 degree days)? Or should i just stick to the regular full synthetic 10w-30 amsoil?
I've run Royal Purple XPR 10w40 in engine and synchromax in trans, since the day I brought my new Boss home two years ago. Installed Barton shifter and bracket after the first week also. No issues and no regrets.
Cool, I just bought 9 qts of Royal Purple 10w40 for my first oil change today. Been reading this and don't trust the Motorcraft 5w50. Seemed like this was the best I could get locally, $10 a qt tho :bash: Even the Castrol Edge and Mobile 1 was that price tho here.
Have you got any ethanol dilution/suspension tests for Amsoil to share? How about water suspension? We tried Amsoil in ethanol fueled racing engines and experienced a high degree of alcohol/moisture suspension/contamination that, unlike RP XPR, did not "gas-off" at operating temperatures. As you know, water and alcohol make lousy lubricants. Holding them both in suspension is not a positive trait. Not trying to bash Amsoil at all, just sharing experience that I think relates directly to today's ethanol-mix gasoline.

XPR was formulated specifically for straight alcohol drag racing applications, so it does one heck of a job.
What Amsoil formulation were you using in your application, and are you referring to E85?
No reports of E85 issues with Signature or Dominator thus far.
Was Dominator 15w-50, Straight alcohol not E85. I would expect E85(min 70% ethanol) to be similar. Alcohols(both ethanol and methanol) are extremely hygroscopic and tend to introduce a significant amount of moisture into the oil system, especially when cold and running in a rich condition. Oils in this application need to have the ability to readily gas-off the alcohol/moisture dilution when operating temperatures are reached. The easiest way to see if you have a problem is to take a look at your valvetrain after the engine has cooled down. Evidence of moisture droplets and/or white-ish(pink-ish in the case of amsoil) oil film signifies a potential problem. Again, my experience is in a racing application, not street use.
Bringing this thread back to life.
Unleashed,
What kind of oil pressures do you see from the 10W-30 compared to the 10W-40 in normal driving? Would the 10W-30 maintain pressure for 1-2 track days a year?
