wrong oil viscosity, bad?

thank you po, nagpa change oil ako kahapon kay speedyfix and ung 20w-50 ung pinalagay ko... sabi ng bro ko parang naging smooth ung takbo.. ewan ko lang baka psychological lang.. hehehe pero observe ko pa in a few days pa kung may impact sa fuel consumption.. again salamat po sa lahat

dont expect too much po na may BIG difference sa takbo ng engine because usually psycholigical lang po yan ( smooth ang takbo, mas tahimik etc).

im not saying na walang improvement but what im saying is dont expect too much. unless may noticeable difference talaga yan.

napansin ko lang nung nag change ako into RP (5w-30) mas better ang FC and mas responsive ang engine ng kaunti. pero regarding sa smoothnes ng takbo, is still the same.

IMO

with older and very high milage engines i suggest using the thicker weights unless you're ok with the possibility of leaks and replacing the oil seals. if you are then using the thinner viscosity is fine din.
