Blackstone comments: These are some nice results! Even though you ran this oil a good deal longer than the last, there's hardly any more wear to show for it. The 3.6L Pentastar powering your Jeep looks like it had no problem with the additional miles, and the oil itself held up well, too. Its viscosity is still in grade, no contamination was found, and the TBN is a strong 3.5 (1.0 is too low). The air and oil filters did a good job, too, based on the normal levels of silicon and insolubles. This all adds up to an ideal report, so feel free to run the next oil even longer. Check back after ~9,500 miles.

Blackstone comments are good. (They aren't always!) Healthy engine with a great oil. No bad numbers. Could have gone another 3,000 miles with that high TBN at the end.

Using higher-spec oils than what the engine computer software algorithm (OLM) assumes you're using, especially in a low-soot port fuel injected engine, means you could possibly go about 1.5x the dashboard light time and miles. I'd use a Fram Ultra XG10955 to match the performance of Amsoil SS, M1 EP, M1 AP, Castrol Edge EP, Ravenol DXG, or Rotella T6 Multi-Vehicle in there. My 1.5T DI gasoline 'soot-maker' (GM 2018) defeats just about any oil at 7,500 miles according to GM.

Nice results from a real nice oil. I would keep running it for 7.5K. What oil filter was on that run?

10k would be a walk in the park for this oil. What filter are you using?

 

[TXHunter]

On that run I was using a Wix filter. On this run I switched over to the Amsoil EA as I'd assumed the report would show it would be safe to extend the OCI out even further.

Thanks - areyou planning 9500 ... or further?
