I need to change oil on my Ford Focus 1,4 16v zetec-se engine year 2000
What oil type do you recomend?
One mechanics told me that ford formula e 5w-30 oil is not so good oil and
that he suggest to put in it shell 10w-40?
Are there any reason for doing that? Car has 105000km and don't consumes
oil. I don't need to fill up oil between changes.
