    Last September 2014, I change oil from 20w50 to mobil 15w40.. The Corolla 1999 2e engine runs smoother, feels lighter and quieter..

    Yesterday, I change it to mobil semi-synth 10w40 .. At first start after the change oil, the engine has a slight knocking sound .. I haven't had a thorough check at the knocking sound as of the moment because I haven't use the car since yesterdays change oil ..

    Could the thinner viscosity of 10w40 cause the slight knocking sound ?? Should I change it back to 15w40 ?? Will my engine suffer damages if I continue to use the 10w40 ??

    Correct me if I'm wrong, but you shouldn't use synthetics on an old engine, unless you have been using it since day 1, right?

    10w40 is definitely thinner.stick with 15w40.

    Di yan totoo, ang worst case na mangyari using fully synthetic sa old engine ay oil leak sa gaskets.

    semi synthetic lng naman ang nilagay ko ... saan po ba mag leak ?? sa head gasket mismo ?? kung magleak po, meaning pupunta din sa daanan ng coolant ??

    sobra ito sir. less than 3 liters lang ang oil capacity ng 2E.

    regarding sa question mo, may mga oil talaga na maingay. kung saang engine oil hiyang yung engine mo, stick ka na dun.

    meron din ako ng corolla with 2E engine, hiyang naman siya sa Delo gold. kaya never na akong gumamit ng ibang oil.

    yung sakin naman, napansin ko na maingay din yung engine using mobil special compared sa toyota mineral kahit na pareho silang 20W-50 ang viscosity.

    Pwede din natin sabihin na bka umikot ang conrod bearings mo sa sobrang nipis ng langis.Bka bumaba din ang oil pressure,pag mas malabnaw ang langis.Ung narinig mong umingay pagstart,sa connecting rod un.chka pag gumamit ka ng fully synthetic sa lumang auto,hindi lang sa gaskets magkakaron ng leak.pati sa valve seals,piston rings.Resulta,mag uusok lng naman ang tail pipe ng auto,Kaya tama ung nag suggest na gumamit ng delo gold na karaniwang ginagamit sa diesel engines.
