[QUOTE="UnleashedBeast, post: 12595583, member: 112023"] Exactly what I expect. This happened to Jeep in the 2007+ 4 door Wrangler. A friend owns one, consumes ~1 quart every 1,000 miles. Reading on Jeep forums confirmed improperly installed piston rings. The OEM says it's normal consumption, but this is a simple ploy to prevent spending millions of dollars on a TSB to fix the issue. They are not required by federal law to do a recall because it isn't a safety issue. I think it's lame, honestly. They should repair their screw up. Thank you for the heads up, I missed it. I will post it here so it gets updated to the list on the next pass. This is the first known sample of HPS from a Coyote. At first glance, it appears HPS sheared to a heavier 20 grade lubricant. I'd guess due to fuel dilution since the lubricants flash point was less than 400, but dilution rates in at less than .5%. I will have to wait to see more trends to know if it's the formulation or fuel dilution. [IMG]http://www.svtperformance.com/articles/2012/Blackstone_Reports/Blackstone_002.jpg[/IMG] [/QUOTE]
