wrong oil viscosity, bad?

[pskipper]

10w-40 instead of 10w-30, masama ba sa makina? vvti engine.

Usually more important than what kind of oil you use between the two are that you are changing it (and the filter) regularly. 10w-30 oil is good in any car or truck, its the one most recommended.

Thank you Sir for the suggestion, ask ko lng po kung ano difference ng 20w50 at 10w40, i called up speedyfix kung ano ang pede sa car ko and they recommended ung 20w50.

...Hmmm, for some yep, but for most vehicles (especially with higher mileage) is no longer recommended ...especially for a 1990 Corolla (w/c is 18 years old already like lhie), so 20w-50 will do the best.

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
