A question about Oil


Distinguished Member
My wife asked me to check the oil level on her Ford KA and the dipstick showed it was nearer the lower of the two marks.
I checked the owners manual and 5W 30 oil is recommended.
I've just come across a 1Ltr bottle of 10W 40 in my garage...can I use that instead?...any harm come to the KA?


Personally I'd stick with the same grade, but it's not going to make much of a difference and certainly won't harm the KA. The lower the first number is then the better it performs in cold weather, but as it's summer (well I saw the sun the other day :) ) it should be warm for a while now ;)

The main rule is never mix mineral and synthetic oil.

I wouldn't mix synths either to be honest. I am puzzled as to why they recommend 5w 30 cos my Focus needs that but it's a 16v, didn't thnk they did the old Ka's in anything but 8v.

The original KA used the old skool Fiesta engine, but they switched to the more modern Duratec engine from 2002 onwards.
