Review on Synthetic engine oil IDEMITSU 5W-30 SN, 4 l by Stanislaw Kobylka (S ᠌

The previous owner used a different oil, but I didn't like how the engine ran. Filled already 3 times in my Kia. I would like to thank the service engineer for recommending him. Completely satisfied with its quality characteristics. Excellent additives, the engine is always clean. Got rid of valve rattling. It felt like the engine was new. When the first cold weather came, I did not notice any changes. All in all a very good oil.
