hindi pa nag palit ng spark plug. pagkatapos na pagkatapos mag change oil para maleak check pinaandar ang engine napansin ko agad na medyo bvumaba na idling rpm bumalik na siya parang noong bago pa siya. Ano ba itong API rating bakit sabi nila masmaganda API SL from API SG sa mga previous replies. thanks

lick on the left pane with the "The Engine Oil Bible" Link
s man,
saw the rating of the fully synthetics, how come the mobil1 oil i use 5w50 isn' t listed sa chart???
kcboy,
click on the link again and read about the "Viscosity and Viscosity Index (VI)." part of that page :)
walang kinalaman sa pagiging synthetic or mineral oil yung viscosity rating. :)
raine,
Did you use the same viscosity when you changed to valvoline? Could also be the oil filter- did you use the same type?
Api rates the oil's conformity to the latest engine requirements, eg, low lead fuels, resistance to shearing, additive package for detergency and dispersants. In short, it rates the oil's capacity to protect new engine technology. But there are oils that work better with certain engines even if the Api rating is not the latest. :nod:
ung caltex energy is supposed to be designed for cars 2.0 & above... pwede din kaya yun with older engines like with a 90' galant?
I'm driving a 89 sentra yung sampaloc ang tawag nila sa engine model actually i think sobrang tanda na nya. Ask ko lang kung pwede pa syang lagyan ng semi synthetic oil? Due na ko for oil change kasi. I heard before kasi na when you use na semi or fully synthetic di ka na pwedeng bumalik sa mineral. Help naman po. Thanks
