another engine oil question....

**shadow** · November 19th, 2007 08:31 AM

went to true value ATC yesterday and looked around for synthetic oils...how would you know kung totoong synthetic oil? I mean iba-iba nakasulat eh, meron 100% synthetic, yun iba fully synthetic, yun iba naman synthetic lang nakasulat...

so among those na nabanggit ko ano yun totoong synthetic dyan? kasi I assumed na dapat 100% synthetic ang "real" synthetic...tama ba ako?

**niky** · November 19th, 2007 11:46 AM

Actually, even many synthetic oils have mineral oil "stock". You have to really research to find out.

Maybe it will help if we list the 100% synthetic oils and the synthetics with mineral base.

From what I know the following are 100% synthetic or Group IV oils:
Motul 300V
Motul 8100 Xcess
Royal Purple

Synthetics with mineral base:
Caltex Havoline Energy

Dont know about these. I suspect they are mineral based but I'm not sure. can someone pls chip in:
Shell Helix Ultra
Petron Ultron Race
Castrol RS
Mobil 1
Caltex Fully Synthetic
Motul H-Tech 100

Castrol Magnatech - synthetic with mineral base
Emerat - mineral
Pitt Penn - mineral

hehehe konti lang maiaambag ko nakalimutan ko na kasi ang iba. . .

**userfriendly** · November 19th, 2007 06:45 PM

Castrol Magnatech is actually semi-synthetic oil.

kaya pala cheap yun motul h-tech sa mga mall based hardware kasi mineral base...kasi I think mura siya for a 100% synthetic oil diba?

pero it says in the package na 100% synthetic siya ah...?

**mazingerZ** · November 20th, 2007 09:27 AM

ooops my mistake, kaya pala mahal P250+ per liter kasi dito . . .

pls dont get me wrong. I said I dont know if they are 100% synthetic or mineral based synthetic. I only suspect they are mineral based. I may be wrong and thats why I asked for someone to confirm.

Hindi lahat ng synthetic oils ay talagang 100% synthetic. Majority are made from hydrocracked oils. Hydrocracked oils are very highly refined oils. These are called group III oils which are different from group IV oils. Group IV are true synthetics or man made.

Basically, Mobil sued Castrol for marketing and selling a group III oil as a full synthetic. The court ruled in favor of Castrol. So in effect the courts defined group III oils as full synthetics.

So now there are:
1. mineral oils or dino based oils
2. semi-synthetic oils which are oils that contain less than 30% synthetic stock
3. full synthetic oils that can be further classified into Group III and Group IV oils.

Nakakalito no.

royal purple ba full synthetic? entry level niya?

**speedyfix** · November 20th, 2007 11:55 PM

not all oils labeled as fully synthetic are real synthetics.

castrol RS is definitely not.

Motul is for the higher 8100 and 300V lines but i'm not sure if the h100 is from a group 3 or group 4 base stock. it's still synthetic but it is the entry level of motul.

royal purple is made from a group 4 base stock so basically the highest in the market except for the group 5 which can only be found in ester based oils like redline and 300v.

i doubt any other locally available oil can match the base stock and additive package of royal purple for the same price.

thats why nagpalit ako, good performance at more cheaper kaysa sa iba

**DonT** · November 21st, 2007 11:08 AM

Are there any stock vehicles na available sa market natin na 'required' ng manufacturer ang full synthetic oil? para kasing 'recommended' lang naman, di ba.

**niky** · November 21st, 2007 05:19 PM

Many high performance vehicles and engines require synthetic, as well as some regular cars that have long change intervals.

it's good to know that RP is of a high quality oil..

migs, anong magandang viscosity sa RP for a diesel? mitsubishi adventure to be exact...

**XTO** · November 22nd, 2007 08:41 AM

IMO kaya synthetic or fully synthetic ang required ng almost car manufacturer sa ngayon ay dahil mahaba ang warranty na 3yrs or 100K kms… sila rin kasi ang mapeperwisyo if engine breakdown arises within that period….. sa synthetic nga naman assured na ang protection ng engine, dagdag income pa dahil sagot naman ng owner ang oil to be use eh.

Marketing is great.

**speedyfix** · November 25th, 2007 06:29 PM

washburn, yep tama ka dyan.

DonT, all porsches, mercedes, bmw's and audis require full syn oil. same goes with the even higher brands like ferrari and lambo.

shadow, we've got the 15w40 diesel oil na RP in the shop. perfect yun

**DonT** · November 25th, 2007 10:49 PM

^ Thanks for the info. How about Diesel Engines..when would you recommend to start using synthetic oils? I have read somewhere that diesel engines tend to break in a lot longer compared to gasoline engines. Maybe you can shed more light on this.

**speedyfix** · November 26th, 2007 10:47 PM

start using the full syn on diesel oils around 10-15k kms na
