The liquid looks good 👍 9990 Oil additive
Delivery was faster but I have to come back to review it again after using it. But it looks good.

Perfect
It does work perfectly as an additive. Cold start is smoother and a bit of reduced engine noise. Remember this is not a magic potion and will not solve any engine problems. Need to put in a few hundred jms and check oil consumption and colour
