Review on Semi-synthetic engine oil IDEMITSU 5W-40 SN/CF, 200 l, 199.6 kg by Wiktor Prusek ᠌

For the past six years, I've been using this particular motor oil. When I drive, I put about a normal amount of strain on the engine. You can go fishing or hunting here. as it happens, the ratio is 60% on the track and 40% outside of it. Every 7,000 miles I have the oil changed. Before that, Castrol was inundated for two years, but after (cold compensators were knocked for), it became of the poorest quality. I choose to switch oil brands. I totally lost track of time and space and forgot. I wouldn't recommend going beyond 8,000 miles per year. especially if the engine is under heavy load and/or high speeds.
