I am not sure I can believe that your Jeep is faster after an oil change. That really is an extreme jump to make. A heavier oil offers more protection. A light weight oil is usually what will allow an engine to produce more power and economy but at the sacrifice of less protection.

There were many variations of pcv systems over the years. What do you have in mind?

Just wondering what elements Blackstone reports on. Do they just give wear products or can you see the additives also (Zinc, Potassium, Calcium etc). If you get the add-pack also, checking the results for the different oils will tell a larger story - how the different additives seem to be helping - anti wear, dispersant etc - keep our poor engines alive

I've taken a different tact by blending 50/50 5-20 & 5-30 (3 + 3 qts) of same brand synthetic...I agree that 5-20 is too light....This blend makes for a good overall compromise & balance, engine doesn't rattle. So far I'm very pleased with the results.

Neat Report!
Just curious, it was interesting to see they flagged the copper as increasing; did they mention anything about the molybdenum? Not to alarm you but the moly increased by 50%. Aren't the piston rings made of moly? Is that just normal wear and within their expected range? Will you post your next report too?

My JK is a 2008, but it has a 2010 short block in it due to a spun bearing under warranty. IIRC, most of the spun bearings we have heard of were all 07-08 models.
