Is it ok to have changing oil viscosities?

[dr. d]

hey, Help me out in this confusion!! Is it good to change oil? Will it affect my car's appliances?? Best Thermostat

change oil... of the car's engine? it is a requirement, po.
nasa owner's manual ang schedule and oil specifications. best to stay faithful to it.

no, it will not directly affect your car's appliances.
but if something happens to the engine because of oil issues, then most of those electrical appliances will be affected, because they get their electricity from the alternator that is run by the engine.

Any one using 0w20 or 5w20?
The Toyota Corolla manual specified both oil, but most of us here either use 5w30 or 5w40.
(Currently using 5w30 for Altis 2011). Will it be too thin kaya for our conditions here?
I really would wanna try and go back to what the manual recommends.

I only use regular oil sa Toyota Avanza... basta change oil every 6 months.. mababa naman odo.. Toyota uses 20W50 for regular oil sa gas engines..

Wala kasing 5w20, mas common ang 5w30, 0w20 naman sobrang mahal. 5w30 ako sa 2013 Civic ko.

IMO. if your car is working perfectly on the current oil you're using, better stick with it.

it's a 10 year old engine... oil seals are not what they used to be.

Sa init dito sa clima natin, di bagay ang 0W-20. I don't use it, even if my manual says its the preferred viscosity.
Yung manual was written for a "Generic" market, not specifically for a market sa tropics, kaya ang daming translation din, tapos may disclaimer pa for variants in EU or Asian markets.

Hindi naman masisira car mo if you use 0W-20 oil here, but personally, I don't recommend it. Kahit sinthetic pa ayan, ang lightest viscosity sa clima natin should be 5W-30 if your emphasis is more on engine protection rather than increased fuel economy.

IIRC 30 weight oil is only good for up to 30°C. I try not to use anything lower than 40 weight for my cars.

Also with our climate the "W" rating doesn't matter at all. It represents the oil flow at 0°F (-17.9°C).

If SAE 30 is good for 5°C to 30°C, 5W30 extends the lower operating range to -35°C. It's irrelevant to us.

[dr. d]

my two cents' worth,
from what i understand,

the W rating may be of importance in temperate countries where it snows,
but in our country, that W rating is of importance because some engines have oil passageways so narrow, thicker oils may have difficulty in effectively traversing them whilst the engine starts from cold.
the other number naman, is the temperature when the oil starts its effective lubrication. by that temperature and higher kasi, the 0 rated oil may not be an effective lubricant anymore.
when you have a multigrade oil, the effective lubrication of that oil is a combination of the two or more grades of oil.

see dr. kamiya's diagram above.
the combination of oils, effectively increases its temperature range.

Sa init sa atin, I'll stick to the thickest viscosity(and highest W) na recommended sa manual.

back in the day, when engine blocks were made of iron,
the best oil was the walang-kamatayang SAE40 or 50.
laluna kung pinaghaluan nang pertua!
heh heh.
highs. the good old days...

[yapoy86]

Meron naman naka indicate sa manual yung temp range na dapat gamitin na oil viscosity..

Modern engine mas tight ang tolerances.. kaya mas ok yung thinner oil.. 5w30 na for me yung swak sa fuel efficiency at protection sa heat sa atin.. may mga bansa pa nga na mas mainit.. katamtaman pa lang here.. ang kalaban talaga sa atin ay traffic at long idling

[gearhead000]

The reason I asked is I've read several owner's manual and for the newer gen engines recommended viscosities are 0w20 or 5w20.
So I did a quick search with our online shops and they're now quite readily available and more importantly, very much affordable.

Wala kasing 5w20, mas common ang 5w30, 0w20 naman sobrang mahal. 5w30 ako sa 2013 Civic ko.

Used to be talaga na either walang mga 0 and/or 20 weight oils dito sa atin. There was a time ang popular pa nga is 20w50.
I do remember with my 9th gen the recommendation is 5w30, but during that time it was something quite rare thus the use of 5w40.
With the newer generation, manual says 0w20/ 5w20 pero again probably just 3 years ago rarepaps pa dito ang said viscosities.

As mentioned, today they are quite aplenty from the respectable brands, and with prices very competitive with the popular viscosities.
Mamili ka between OEM's like Ford (Motorcraft), Mitsubishi, Honda, Hyundai, Suzuki, or manufacturers like Aisin, ACDelco, Idemitsu, Mobil 1, etc.

That chart though is quite an eye opener, though I may still not be using 40 weight on my 10th gen.
It spelled for us in an easy to digest way the usage of these various viscosities, either monograde or multigrade.
I may probably stick with 5w30 going forward. It's only a 0.5~0.7% gain in efficiency with the thinner oils.

Sa weather natin sa Pinas, W30 talaga minimum na ideal. Sobrag nipis na yung W20 pababa imho. Yung W40 nga okay din eh lalo na kapag uminit na makina, mas swabe na yan.

Ang baba nga ng viscosity na nilalagay ng honda sa crv diesel eh. Para siguro tipid sa diesel consumption.
