Recomended Oil Viscosity?

[weszt]

Hi! Just want to ask for all the owners of 1.6LS Optra. What oil viscosity are you using? which is more suitable for our car, 10w-30 or 10w-40, and what brand? thanks

IMO 10w-40 for N/A engines are too thick.

better use 5w-30 on it and also for a better FC.

I dont own an optra but I use Royal Purple 5w-30 on my 1zzfe Altis.

sir, ano po nakalagay o recommended sa manual? 5w-30, normally po ata sa mga cold countries, like canada or US, para di hard start.

I use Motul h-tech 100 10w-40 .

check your car's manual...

in my manual it is stated to use 10-30W, but now im using 10-40w shell helix semi-synthetic blue container..

Semi Synth ba sir? How much ito ngayon?

weszt,
the SAE (society of automobile engineers) viscosity index is 10W-30 or 10W-40 not 10-40W nor 10-30W. the "W" is for winter grade, you can disregard this if you are in the Peelipins as we do not have winter. what matters is the summer grade of 30 or 40, the higher the number is the thicker the oil but your MPG is a bit lower. the thinner oil on the other hand has better MPG but the engine will be a little bit noisier. use what is recommended by the factory. just make sure the API (american petroleum institute) is SJ or better for newer cars.

balak ko mag pachange oil at 40K gusto ko sana castrol fully synthetic. mas ok daw ung castrol kaysa mobil 1 eh.

mas ok siguro sa akin yung 10w-40 baka kasi masyadong thin yung oil pag 10w-30 yung gagamitin ko eh yung normal ambient temperature sa atin eh lagpas naman talaga ng 30 eh.

Dati Castrol gamit ko kaya lang madaling magkaroon ng sludge ang makina ko pagbukas mo ng valve cover . Ngayon Motul Htech 10W40 fully synthetic at maganda at hindi nagkakaroon ng sludge at magaan sa makina at tumipid sa gasolina.

[weszt]

ah ganun ba? baka hindi fully synthetic ginamit mo?

natry mo na ba ang mobil 1? nag kasludge din ba? alam ko sa panahon ngayon lahat ng fully syn na oil wla ng sludge...

bro sa pagkakaintindi ko sa chart ng api oil 10w = pwede sa lowest outdoor temp na 0deg C, http://www.aa1car.com/library/API_ratings.pdf
at ang 30 naman lagpas pa sa 40degC otside temp.
di porke 30 ay 30degC na ang max na kaya nito.

raine is right. the SAE numbers do not directly represent the temperature but rather the oil viscosity. for example: 10w40- the 10 represents the thickness of the oil at 0 degrees celsius and the 40 represent the viscosity in warmer climates above 70 degrees celsius. please check your owner's or service manual and do not rely on hearsay from your "mechanics" who barely graduated from high school

ok then thanks for the information, medyo confuse nga po ako.hehe

so what brand of oil can i use that meets the API and SL - ILSAC classification or exceeds. i want to use the oil in SM category that have an oil viscosity of 10 W-30, any suggestions?

[raine]

para saan sasakyan mo ba gagamitin? kung hindi ka naman namimili ng brand meron ang honda VTEC LEV 10W-30 nakakabili nityo sa CASA ang mineral oil nasa 8++ pesos / galoon. gawa ng idemitsu

[weszt]

para sa optra po, mas preferred ko yung shell, mobil 1 or castrol kaso di ko po alam kung na exceed ba nila ung requirement. ano po kaya

[raine]

kung ganyan brand ang gusto mo, marami sa ACE harware kaya lang medyo mahal, kasi ako specs ang tinitignan ko di brand, well kanya kanya tayo.
