I almost didn't post this question because of the wide variety of emotional responses I know it'll trigger. However, I do like reading the different perspectives, so here it goes:
I took delivery of my 2-door JL Sport in April of this year and just did my first oil change at 3200 miles. Roughly speaking, 70% of those miles are city driving, 20% highway, and 10% light/moderate off-road. I sent an oil sample to Blackstone, who stated:
"This is a wear-in sample, so we're not surprised to find more metal and silicon than average. Once wear-in washes out, metals should be more akin to universal averages. Silicon is from sealers and lubes needed for assembly. The remaining elements are mostly additives in the oil, and it's fine if they don't match up perfectly with averages. Not every 3.6L Pentastar owner is running the same brand/blend. The 4.2 TBN shows active additive to spare and the viscosity read in the 5W/20 range. Nothing looks like a problem in the early going."
While everything looks good, I'm concerned that I may have changed the oil too early because of the amount of remaining additive in the factory oil. As such, I'm just curious what the additive really does, and if it would have been better to let it run through the engine until the oil life was closer to 0%. No need to argue about oil life, type, viscosity, metal shavings, etc. ...that's a dead horse that's been beat into glue many times over. I only want to know more about the additive and any benefits it might have provided for the new engine. Thoughts?
