Can you really verify by analysis if you are getting any "coking" (burnt oil deposits) under the piston crowns? Since we run uniquely hot in this area compared to almost any other engine, I would be very interested in this prior to increasing my oil change intervals.
Thanks in advance.
And kudos to Jmatt again for publishing an oil expose'. I just changed to 15w-50 Mobil one to kill the dreaded whine, but I'll quickly choose another oil for the future.

I posed your question to Brian, and here is what he said in reply... the delay was due to his traveling prior to seeing my PM.

First, the Magnuson-Moss act prohibits DCX or any MFGR of a "parts, materials, and workmanship" warranty from refusing warranty coverage because you didn't use "ABC or MOPAR oil". It has to meet the API and SAE specs and grade, and that is all. They do not warranty anything that they do not produce. That is why in the owners manual it gives specs, not brands. They can only suggest.
The second part to the question is carbon buildup around the piston crown and under the piston.
I produce a Mineral Synthetic base material of my own design that has ALL of the reactive hydrocarbons removed before it is ever blended. As on our site, we heat up a Stainless Steel panel that is 6'x6' to 600 degrees F and test each and every batch for any reactivity. If it doesn't pass, it is sent back for more regeneration. If it does pass, it is then used to make the different blends that I engineer so that each gallon is correct and blended appropriately. Since there are components that bolster the oil to withstand all the heat that these engines can produce including flame kernal (3500-4200 Deg F) Our oils withstand over 6000 deg F combustion temperature. No way we will leave ANY deposits period. Clean, lubricated and protected far beyond anyone elses lubricants.
Hope this helps your friend. Regards!!

I just changed out our Heritage Edition oil at 7300 miles service. Am sending it to Blackstone for analysis. When I get those results I have requested two sample bottles so that I can send the virgin oils in for a baseline analysis. When the MSRT8 comes up for it's next oil change (planning for 5k miles on the oil, and only 6k miles on the MSRT8), I will send that it for analysis before extending further. Either way, I don't plan to go beyond 10k/change with either vehicle.
Matt (vvv90)... Brian is based around the Cleveland, OH area. He should be familiar with weather similar to Chicago, AND he owns an '06 Charger SRT8. So me thinks the *** oils, coolants and Fuel Catalyst are designed with racing performance engines (and the weather) in mind.
