Hello, soon I'll need to change the oil in my 1.9 jtd. Now I have a 10w-40 oil. And looking for something with higher viscosity I accidentally saw this oil Car Engine Oils | Products | Mobil Superâ„¢ 3000 Formula FE 5W-30 at 24£ 5 liters. Is this suitable for 1.9 JTD engine if is't Formula FE? Is the price good?
