STP 11665 XL cartridge 6,250 miles

Her Jeep gets pretty much all highway. Her commute is about 17 miles each way. Bi-weekly trips to the grocery store which is about 30 minutes all highway. We live in an extremely rural area. So its country roads and highways everywhere we go.
 
Yeah, looks good. As the Pentastar cartridges application is a relatively long narrow one, a little wave seen in some not unexpected, imo. Or, a problem.

In my observation of post use anecdotes posted, the Mopar OEM have looked good. And many were very happy with the Fram Ultra XG with polymer backing made in S.Korea. Unfortunately, those have been superseded with made in Brazil XG that don't look to be the same quality.

Based on pics here, I'd have no problem using topic STP for Pentastar application.

Thanks for pics.
