Subaru forester, 2022, Japanese. We change by mileage 5-7 thousand km. There are no complaints. We buy from different sellers, through the market (more expensive in stores). So far, I haven't come across a counterfeit. We operate the car in a quiet mode (city, highway), without prolonged extreme loads. The engine works great. The oil darkens, but within reason. No worse than Japanese oil (Toyota corolla fielder Toyota oil).See full review
