    Last sat, nag pa pms ako ng crv for 2 yrs/40k mileage ko is 26k. We have been using 5W-30 oil and nag 0W-20 ako, may problema ba dun? wala naman? wala naman ako napapansin, pero meron ba dito pwede magpaliwanag kung ano pinagkaiba nung dalawa. sabi nung sa, semi daw yung 5W-30 and Full daw 0W-20...pero alam ko Fully Synthetic talaga ginamit namin after a year so nagtaka ako bat ganun sinabi nya....


    help naman...

    ito na ata ang default fully synth motor oil ng honda ngayon. parang ang nipis masyado kaya palagay ko hindi ko na ilalagay sa '06 fd namin baka 'di kayanin ng seals nun

    btw, bs lang iyong sinabi ng SA. gusto niya lang siguro i-push iyong 0w-20 langis na ito

    If you want to prolong your engine
    and give it the maximum protection you should, and you don't need fuel efficiency, this is the ideal oil weight for a gasoline engine.
    0W-40
    5W-40
    10W-40

    the lower the second number, the greater chance that the oil will shear faster providing less lubrication.

    masyado mababa ung operating temp ng oil viscosity mo lalo na 40k mileage ka na imo.

    Sir miko, what will then be the proper oil viscosity if fuel efficiency ang habol ko?

    yan na kasi yun oil nila for the new models, kaya wala na sila nun 5W-40 na fully synt...

    Sir retz if gas engine ka tapos primary factor mo is fuel efficiency, the 0W-30 or the 0W-20 would give you the best mileage...
    pag sa diesel engine ginamit yung weight na yan for sure taas sobra ng wear rates and definitely sira turbocharger and engine after sometime...

    honda might be advocating that wieght of oil para ma-achieve nila yung promised fuel efficiency ratings nila sa models nila...

    fuel efficiency achieved through the use of those weights would at the very best and perfect conditions give you just around 1k/L advantage.....

    True.

    20 or even 30 weight oil is very thin. They are fine basta nasa normal operating temperature ang engine, pero kawawa ang engine pag nagka problem sa cooling system/nag over heat ung kotse.

    Bagay lang to sa brand new or cars na walang history ng overheat.

    my new toyota uses 0w-20. according to my mechanic 0w-20 is strictly for new engines and highly recommend i switch to 5w-30 after about 20k miles no matter what casa says. ill stick to what factory uses (not necessarily what casa suggests). id like to hear tsikot experts take on this.

    ^Eh paano kung wala ng 40 sa market kasi sobrang laos na?

    i doubt that will happen in the foreseeable future.
    ang daming lumang sasakyan na laos na.

    With oil resources getting depleted & scarce, thick oil burns more fuel its probable in the near future govt will ban the use of thick oil

    That will be the end of the so called ideal 40

    probably be more effective if govt bans old vehicles instead.

    Old vehicles will work with thin oils

    Only if the engine was designed for it. There's a balance to be achieved. If the oil is too thick, it adds drag and loses efficiency. If it's too thin, there's lesser drag but excessive wear could become an issue.

    Then again, you have to define what "old" means. To me, it can mean two things or a combination of both.... that the engine is at least 1 or more generations old and it came out during a time where standards were relatively less stringent, etc. Then it could also mean it's been worn down.

    A seldom-used 'old' engine would still have close to factory-tolerances while the same or even slightly newer engine that's been run through its paces wouldn't. To a varying degree, both these engines would consume/burn oil if a thinner motor oil is used.

    During the designing, the engineers have determined what oil viscosity their engine requires. If it's 40-weight oil, using a 20-weight oil or thinner will likely increase wear and tear.

    Another consideration is vehicle purpose and duty. For light city driving in a modern econobox, 0W20 oils are fine, unless otherwise specified or you do a lot of spirited driving or you occasionally take it to the track. For performance and heavy duty vehicles, 0W20 would likely be too thin.

    Very true.

    When I was still driving my preowned '89 Daihatsu Feroza, "kumakain na ng langis" as the old saying goes especially during long trips. Back then, the classic Castrol GTX 20w-50 motor oil was a standard for petrol engines. So this was my motor oil then.

    For a typical summer trip to Baguio (Holy week), Makati to Pozorrubio (stop over with coffee break), 600ml na ang kinain na langis. So I do the normal "top up". Upon reaching Baguio proper via Kennon Road, another 200ml ang nabawas. That's almost 1 liter, one way pa lang. Going back to Manila is a different story. 500ml na lang ang kinain upon reaching Makati.

    One day I tried Pennzoil 10w-30 (just a conventional) motor oil. Another yearly Holy Week trip to Baguio with the same stop-over at Pozorrubio, 1 liter na ang kinain na langis! Hindi pa ako nakakaakyat niyan ng Kennon Road. So to cut the long story, using a "thinner" motor oil (i.e. 10w-30) made my "old" engine consume more oil than the conventional "thicker" 20w-50. When I went back to 20w-50, yun oil consumption was less.

    These are just my observations (based on my story above) on the issue of using thinner oils like 10w-30 on older engines:

    1) More oil consumption during long trips under hot ambient temperature and high altitude driving = higher engine revs.

    2) BETTER cold starts

    3) No effect on fuel consumption.

    Again, these are just my observations.

    And old vehicles running on thin oil will burn less fuel

    "air polluters", esp. if the vehicle is not maintained well.
