Engine Oil - All About It

[crossroad]

if new car use synthetic, but when your car gets older there will come a point you have to switch to regular oil. either way you have to change every 5k, and not the 10k as recommended(synth). yup was also surprised cuz i use synth and change every 10k. so if your not into hi-po better use regular and change every 5k.

Fully synthetic din.

[yhance]

Fully sythethic oil is always the best especially motul

[Seaman69]

Fully synthetic, you save more on the long run, good for the engine pa

[miked]

finally switched back to motul htec 10w40 for my cefiro. initial observation was that engine noise at idle. its quieter. to think that i only poured a 20w50 oil that just ran less than 300kms before switching. engine also revs freely. fuel consumption improved. my car is a guzzler. the best i could get before was 6-6.5km/liter. now i think i could get close to 7km/liter.

just switched to helix fully synth...

but was too late since i read some negative feedbacks

still i am observing it, so far running good but will

take some time to see the real output > 2000 kms up

[cooldude247]

Castrol Fully Synthetic.... cleaner and better.

[Zarbor]

20/50 oil changed every 5000km

[amaro119]

Castrol edge 5W40 100% synthetic for my Civic 2005. I usually change it at 10,000 km. I have 72,000 kms already so i will definetely change the oil at 9000km now.

synthetic all the way! try motul or royal purple

paano natin malaman na tunay na synthetic ang langis? Dami kasing peke at wala namang regulating govt agency na nag che check.

You mean what is a genuine synthetic? What I said sounded like an oxymoron.

[ricoyan]

If you are an oil PURIST, The TRUE synthetic oils are those PAO (polyalphaolefin) + esther based lubricants. These are expensive to manufacture kaya mahal ang MOTUL, AMSOIL, ROYAL PURPLE.

 

Some oil companies have "FAKE" synthetic oils because they use a PETROLEUM-based (therefore not man-made) hydroisomerized stock lubicant. Unfortunately, CASTROL, PENZOIL, and most other CHEAPER synthetic oils fall under this category.

 

There was a big lawsuit in the US because of this. In the end, naka-lusot mga fake synthetics as the courts allowed a less stringent "synthetic" standard.

 

I took BIOCHEMISTRY kaya alam ko maraming pwedeng idaya sa Hydrocarbon molecules. Konting tweak lang sa isang molecule, iba na ang result.

 

Basta the general rule is:

 

NOT ALL SYNTHETICS ARE CREATED EQUAL.

[clayman688]

synthetic for my newer car, regular for my other older car.

[edc]

Lately ko lang nalaman kung city driving lang eh hindi nagkakalayo sa performance ang mineral sa synthetic...

 

Pero pag turbo ang engine eh kailangan synthetic talaga.

 

Pero regardless sa dalawa eh kailangan palit every 5thou kms/6months.
