oil completion

I'm going to complete the car with a bit of oil, but I don't know how many oils he put in because the oil changed the owner before me, is there a way? vehicle 1.6 gasoline

The big contingency is 10-40. You can complete with 10-40, of course, my opinion.

I think 10-40 is likely

I think it is, but if it is not 10-40, would it create a problem?

If the ideal oil for 10-40 o car is already 5-30 in it, it gets a little thicker. I don't think it will be a problem

why does fat decrease so I think take a look at this

[QUOTE = Kifanhom] why does fat diminish, I think take a look at this

[/ QUOTE] The reason is that when I picked up the car, it was a little above the max line, I pulled it from the oil filler cap with a large syringe and serum hose, I pulled it a bit more, of course, it was a little below the middle of the two lines, then about 4000 km or so, something was less, but it is between min and half. I looked at the oil filter, I think there is a little oil there, I didn't care because it was a little lost, I did not care, I did not tighten it, when I was going to change the oil somehow, there was some water in the container where I drained the oil.
