I rechecked my owners manual for my Mazda 6 2.0 and the oil they recommend for Greece is 5W-20 API SL/ILSAC GF-III or 5W-30 API SJ/ACEA A1 or A3. Temperature in the summertime in Greece can go as high as 42 C (110 F). In the winter I seldom see anything below -5 C (20 F).
1. Will the 20 weight oil cover me, or should I go with the 30 weight? I drive hard and red line is reached often.
2. Is there any difference if instead of 5W - 20 and 5W-30 I use 0W - 20, or 0W -30 such as the Fuchs Titan GT1 and Aral oil?
3. What is the ILSAC classification? ![[Confused]](images/icons/confused.gif)
