Some improvement but not by much
I added this to Zen Estilo to help improve start-up and reduce noisy valves. However, I didn't notice much improvement in these two aspects but engine pickup had improved in 2nd gear by a lot. Yes, it works but not in all aspects and it can vary according to each car. 300ml quality is a lot and I added this oil after 3 months of engine oil change (however it wasn't driven for even 1000kms during this time). I'll have to see the improvements only when driving it more often. No harm in adding this to your engine oil but if you can afford a good quality fully synthetic oil, then it should be ok.

A must buy for old cars
Amazing product. After just 5 minutes of filling it in my engine oil, I could hear a smoothness in the sound. The sound keeps getting better over time. I’ll buy every time I change the engine oil from now on.

Good enough for a small budget.
Was good. Quite thick. Thicker than 3M. But might have reduced mileage a bit. Decided to go with liqui moly in future. But worth the price.
