Hi guys, this is the first time i post thread here. Let me know if i didn't follow any rule.

My RC350F sport just hit 30k milage and i got it used. It is time for oil change!
The manual said the oil grade needs to be ILSAC GF-5.
But most of the oil i found is ILSAC GF-6A.
Can i use the new grade with SAE 0W-20?
I have read through the user's manual and couldn't find the information of oil filter.
Do you guys have any recommendation?

 

"ILSAC GF-6A can be used to meet GF-5 oil recommendations and earlier. GF-6A products will display the “Starburst” API mark. GF-6A is backwards compatible, meaning it encompasses GF1-5 standards as well and is designed for SAE grades 0W-20, 5W-20, 5W-30, and 10W-30."
