“I'm actually running this for the first time with a fresh oil change in my old VW T4 2.4d. I also use dthinner oil than usual this time around (10w40 instead of 15w50) and I also changed the oil after only 5k km instead of 7.5k km. Instantly I noticed a massive reduction in engine noise with a smoother operation - since I've had this vehicle for 15yrs, I know it's not just a fresh oil change.”
