Bro i have just checked. They have 3 types of oils depending on drain intervals; 25K miles or 1 year, 12K miles or 1 year (whichever comes first) and OEM recommendations.
I can not say anything about 25K or 12K drain intervals oils; experts or those who have experienced them can guide better, and whether 25K or 12K miles drain interval oils suit us or not? (considering our environmental conditions). However, regarding drain interval, i think you must change when you observe that oil has got dirty.
