Mineral , semi synthetic or fully synthetic?

[nivraarvin]

Brothers, anyone who have used the oil below? Its 0w20. Okay daw for new engines. for some reason am still not convinced. hehehe!

For brand new cars or cars that has no history of overheating pwede. Also, pag econo drive ka lang palagi.

For older cars that may run hotter engine temperatures, pinaka safe ang w40.

Pag nag overheat ang kotse tapos w20 or w30, the oil will become very thin(during the time na nag overheat) and baka magka magka damage ang engine.

[miko101130]

Pwede 0w-20 for very lightly driven vehicles which will never experience hot, humid, dusty environment... And mostly driven in highways...
The 20 weight will shear faster due to its thinness, pero depende yan... If PAO base then kahit manipis ang weight it could still withstand shearing of the oil...

Definitely a no-no for diesel engines yan...

Sa 20weight na oil, you could only get a maximum of around 5 percent fuel efficiency...
Ang mga manufacturers ay hell bent and focused on fuel efficiency that is being push by government agencies, one key component nun ay sa engine oils.

Mas kikita sila if hindi tatagal ang engine....

^That's why it pays off to read and research online. I read this thread 2 days ago from page 1. All worth it. Thanks to you guys.

Been reading this thread also, ngayon lang natapos. But I quote above, pede at pede ring hindi sila kikita if hindi tatagal yung engine. In the short run, maybe. Kasi bibili ka nga naman ng parts. Pero hindi ka na bibili sa kanila ng bagong kotse, 'cause of your experience. Without knowing, part of the reason of the premature engine failure ay yung oil. In a laysman's point of view, like mine, pag nasa casa ka, sige maganda yang synthetic basta synthetic yun na yun.

My only question is, how many years did they spent on R&D, to come up with this w20 oil or did they? Lol

Check your car manufacturer's recommended oil viscosity grade kung pasok ang 20.

Nabasa ko yung 11 chapters ng motor oil 101 sa bobistheoilguy.com

ang sabi nila, 90% ng engine wear eh nasa pag start ng kotse, so dapat daw mas malabnaw ang langis mas maganda.

Kumbaga ang naintindihan kong conclusion eh ganito

Mas ok ang malabnaw na langis kumpara sa malapot, kasi pag malapot xW-50, matagal pa bago lumabnaw para sa optimal viscosity para ma abot yung engine parts sa startup.

Ang pinaka ok daw eh ang mga xW-30, then yung xW-40, in some cases.

Ang advantage lang daw ng mga FS na xW-20 eh kung madalas ka lang na short trip, yung tipong gagamitin mo kotse, patay makina, matagal ulet bago buksan, then andar ulet. Lamang ka dun sa sinasabing 90% of engine wear is at start up. Pero syempre kung madalas ka ba-byahe, hindi natin masabi diba? Mas protektado ka sa xW-30/40 kumpara sa xW-20 habang nasa byahe...


Correct me if I'm wrong ah, medyo antok nako nung binasa ko yun eh haha...

0w40 is better than 5w20 at start up.

0w will have a lower viscosity than 5w at 0 degrees celcius. We can safely assume that it will still be the case at tropical temperatures, though the difference may be smaller. But still, 0w40 will flow better than 5w20 at "start up".

the best oil would be a FS 0W-40... problem is mahal ito... dahil fully synthetic lang ang pwede magka 0W, and yet weight 40 siya.. kaya 0W-40...
so dahil mahal siya other alternatives will come to play like 10W-40 and 15W-40....

There is minimal difference between the viscosity of 10w and 15w...
basically sir parang ganito ang final outcome

if kaya budget mo, the best is a 0W-40 oil!... like MOBIL 1 fully synthetic
if hindi kaya budget then you have to have some sacrifices, you will go to the cheaper one which is 10W-40 and 15W-40....
kaso they don't fully FLOW and circulate agad for the first 6 seconds on morning starts...

so the best way is that "if you are using 10W-40 and 15W-40, idle it up without load for just less than 1 minute during morning starts... then you're good to go"

no harm done to your engine... and possibly to your pocket...hehehehe...

Hehe, gawain ko na yun na few minutes bago umandar, mahirap na.

Salamat sa correction!

does the 0 degree Celsius apply to a tropical country like Ph? siguro kahit month of December or January which is the coldest in Ph, your engine will not attain 0 degree Celsius in the morning before staring it.

[nivraarvin]

That's why i said that we can still safely assume that 0w will still flow better than 5w at start up with tropical temperatures, though the difference may be smaller with respect to their viscosities at 0 degrees celcius. For the sake of answering the question, which will flow better/which is better at "start up".

Note that what i meant by start up at tropical temperature, the engine is "cold".

the OW means its cold properties.... its like this...

0W-30
0W-40----------------best in flow(cold start) best in heat(operating temp) # mahal dahil fully synthetic toh.
5W40
10W-40--------------mostly for general gasoline engine use... (good with heat) # mas mura
15W-40--------------ideal for dieseils and pwede din with gasolines. (good for heat) operating temp. # mas mura...
20W-50--------------not ideal because the thickness during start-up... but performs also in the heat range..(pang fleet service na constant umaandar engine,>8 hrs)

pag 0W simula mas ok yan sa start-up, basta 40 din ang last oil weight para pag mainit na engine protected din...
(you get the best of both worlds at the expense of your pocket) !!!!

0w40 is better than 5w20 at start up.

yes 0w40 is way better than 5w20 at "cold" start up but practically NOT applicable in Ph driving environment AFAIK.

If you Google the application of 0w40, it is used mostly in Europe and N. America or any other countries where "cold" term is applicable.


anyway, I found this oil guide which I think can be good reference for all of us

overkill na masyado gamitin sa pinas at ordinary PC ang 0W pero kung hindi problema pera go for it, its your car and money anyway.

Yes, I agree. But i was not answering the practicality question.

An engine at 25 degrees celsius is a "cold" engine.

[kompressor]

Yep. Kahit nga tirik ang araw and 36 degrees na sa Metro Manila, a 36 degrees celsius engine is still a "cold" engine.

Kaya important din yung merong engine thermostat. Half of the engine's operating temp on 10w-40 oil will result to your oil weight being thinner than SAE40. Engine operating temps should be more than 88deg C.

To conclude, kahit walang winter sa Pinas, mas maganda talaga ang multigrade oil kasi nakakatulong ito sa pagiging mas malabnaw during cold starts para madali mag circulate ang oil then gets thicker pag operating temps na for maximum protection against metal to metal contact ng engine moving parts. Mas mahal lang talaga compared sa monograde. Pag monograde kasi, obligado wag mo lagyan ng load ang engine during a cold start and mas mabilis mag wear ang engine moving parts pag mas madalas ang cold starts.

[miko101130]

basta ma-idle for a minute or less ang engine, enough na yung oil na nag circulate to properly lubricate,,, then wag lang i-race, low Rpm's lang until nag hot na sa thermostat... para ma minimize wear....

and don't forget, with good oil, dapat good oil filters din like baldwin and fleetguards...

[Retz]

nasa driving habits din naitn kasi, ung ibang driver pagka start pa lang, arangkada na agad.
