hi,

currently i am an turbo xp oil user (since my car was bought year 2000). until now. so far ok naman ang takbo nya, yun nga lang balak ko magpalit ng oil to royal purple. me tamang step ba kapag magpapalit ka ng brand oil? or simpleng drain lang overnight, ayos na?

ang balak ko kasi ganito:
- drain overnight
- put higher weight royal purple
- run for 1km
- drain oil overnight
- put the right weight of royal purple
- change oil again after 5km

or overkill ang ganito?
