Xdp x factor oil additive
This stuff works as advertised, I have a older 02 6.6 Duramax , It definitely quieted the engine. Don't hesitate on buying.
Used this product in my 6.6 Duramax. I was surprised that it seemed to smooth out engine performance and quieted engine noise and even lessed some of the droning in the cab from my 4 inch straight pipe exhaust. Seems to be a good product from xdp.. as good as rev x brand but cheaper

Good stuff / order # 1669230A
I used it in my Cummins. 1 bottle. With oil change. 5000 miles and it is starting to smell like onion field in July. I am sure if I used the 3 bottles recommended, I would still be good. I use it in my zero turn mowers also. Normal use with synthetic oil in the zero turns at 20 hours the oil is done. With a half a bottle in the motor I am getting another 15 hours. I have a 14’ suburban with 136k and would have to put 4 qts. In at 1500 miles. Now with 1 bottle added I don’t add but a quart of oil at that miles between changes. I do believe it works.
