First I do not have user's Guide of my car Skoda Felicia 1.3 cc injection.

And my question is: What type of oil is used for motor

(10-40) - (20-50) W.

Thank you

Now about the engine oil. In your country it is recommended to use 20W40 or 20W50 oil.

Ok dear sorry for the font ... you mean in a summer I can use the 20W50 oil !

and in winter 20W40 ? and please I have another question how many Litter oil, 4 L with filter oil or 3.5 L with filter oil. 

Thank you dear ...

@KhatabMKhatab - Do you actually understand oil viscosity properly? I suspect not, or you'd know that the only difference between 20W40 and 20W50 is how fast the oil thins as the engine temperature rises. (40 grade is thinner at operating temperature) https://en.wikipedia.org/wiki/Motor_oil#Grades is a good lay explanation.

Thank you dear I understand now @KenONeill
 

It all depends on how high and for how long the outside temperature gets in your area. I think in Jordan you get 35 C in summer and 10 C in winter, plus/minus 10 C. So I would use 20W50 all year.

@RicardoM Thank you dear (Y)
