Will extend your change intervals
1 of 1 found this helpful Have been using Royal Purple in my 2014 Ford F350 6.7L diesel for 90,000 miles. Have extended my change intervals to 20,000 miles, I do an oil analysis every other change and the report says I could go even longer if I wanted to.

Must have accessory for a diesel truck.
plugs in perfectly, infinitely adjustable, looks factory made, this is the second truck I have installed one on. An excellent product. Becareful who you buy from though.

Give it a try.
It is a serious upgrade over the stock OEM damper. Excellent value for an immense performance improvement. If it's longevity shines it will be a 5 star product.
