I dont know, if it helps and what you think of it. I bought in last october as every day driver a lincoln navigator 2007. After 2 weeks there was a ticking noise in motor. At youtube i īve seen any videos from seafoam spray and liquid. I thought, i make this and put it in the tank and motoroil. After ca. 300 km i changed the oil and filled it up with new oil and lucas oil stabilizer. I did the procedure with the spray in throttlebody too. But for me i can say: the lincoln runs really better and have now no noise in motor.
