Hello, and Hi to you all. I am new to Honda ownership and have a question about engine oil. My car (2007 2.2 diesel I-CDTI) seemed to have 0W-30 engine oil in it when I bought it. I just went for an oil, change as advised and the garage have put 5W-30s in it. I am concerned as I have heard that the wrong oil can cause problems in these engines as they have things like hydraulic lifters for the timing chain. SHould I return to the garage? Thanks in advance. Toto.
