Reviews of Lucas oil additives

I decided to flush the engine any way first before I started the job and pulled the engine out. I put two bottles of car lube engine flush in the oil because of the amount of oil it holds (8.5l) and left the car ticking over for 45 min's wile I cleaned it. I took the car up on the ramp and drained engine oil and filter. Wow the oil come out black like a diesel. I decided to put new oil and filter in and run the car. I added Lucas additive run it up. I erased the fault code and took the car for a run. Omg the difference the car was like a rocket and no fault codes. Its been 7 days now and its like a different car.

it's not the OIL that made my valvetrain noise worse....it just may be the Lucas additive. I was thinking that it might be bad when I was pouring it in, too; that stuff is like thick, sticky glue! Maybe the thickness of the stuff just isn't coating the lifters, because I can't believe how bad they sound.
