not tight enough
It did slip on my BMW M5 F90 oil filter — it wasn’t tight enough. I had to use a microfiber cloth to fill the gap and make it tighter in order to loosen the oil filter.

Works as promised
Size: 2-Pack
Great product! Highly recommend. My check engine light turned off quickly, probably less than 20 minutes after I added the bottle to my tank and started driving. I waited a week to write the review just to make sure the check engine light didn’t turn on again. Success!
