I have had splendid experiences with pso products, provided that you get the original products from authentic outlets. PSO carient 5w30 fully synthetic is a ver good variant indeed. I have been using pso 10w40 in my cultus 07 previously and have had no issues.
However, my neighbor has a civic 9th generation and as been feeding it with pso 5w30 since years. the car has almost clocked 80000 kms on odo. He claims that the oil gives him a decent engine performance plus fuel economy, provided that you go for a good quality oil filter too.
