hello guys i have a 96 mit lancer itlog and balak ko mag change oil. i've been using mineral oil ever since ( di ko lang alam kung ano nilagay ng tatay ko kung sya ang nag chachange oil). balak ko sanang gumamit ng semi or fully synthethic oil. will this do any good to my car or should i just stick with mineral oil? kung mag shift nga pala ako to semi-synthetic do i still have to flush my engine and and if so how mush ung pang flush?
thanks!
