Excellent engine oil!
It was put in a Mazda 2 2012 manual transmission.
Very good feeling in gear shifts.
Before I put it, the 5th gear would make a small click when it was disengaged.
Now it is not heard at all.

Excellent gearbox lubricant. Same or even better feeling in gear changes compared to the original Ford oil (75W90 BO). Tested on a B15 gearbox Ford Fiesta.

A mediocre valve oil that has a good feel as long as the car is cold, protects the soft metals in the gearbox, and has a very low price. It is in no way comparable to Motul or Elf NFP, especially when it warms up, it is worse than when it is cold. Finally, it seems to lose its properties quite quickly (2 months). Personally, the two times I chose them, I changed them every year (while the manual says every 30,000), and I would not recommend anyone to keep them for more than 10-15,000 kilometers.

Excellent lubricant, meets the specifications of all manufacturers. However, great caution is needed with all Castrol products to ensure that we are purchasing an authentic product! Due to being a top company and widely recognized, it is a target for counterfeiters seeking easy profit. With a little research on the internet, you will see how to identify the fakes.
