wonder where can I get Shell Helix Ultra 5w-30 (not 5w-40), is it available in Malaysia?

you said engine oil eating. would  not that indicate a problem with your piston rings ? why not change them ?

Can this full synthetic gear oil (SAE 75W-140) be use in Kancil.
Is this gear oil's viscosity too high for Kancil?


At the moment am using pennzoil gear plus 80w-90.

Hi, sifu. Can myvi use 10W40 castrol oil? Or just stick back to 5w30. Thanks, all.

stick back to 5w-30
by moving to 10w-40, ur FC consumption will be higher, engine less power and less protection.
the gap in myvi engine are designed for 5w-30 where 10w-40 will be thicker.
so possibility of some area not protected by the oil it higher because it cannot slip thru it.

from  a rough read (very long article, so glancing through/skipping and mainly focused on "zinc" keywords)

basically any car with catalytic converters and oxygen sensors (almost every modern cars? not my age old iswara though ) will face potential accelerated degradation with higher zinc additives.

however yeah, zinc is an additive that bonds to your engine parts and from a laymen description based on the article, it is a "sacrificial coating" to protect your engine parts.
which i supposed, is very essential for performance/race engines (as they have little to no regards towards the environment having cat cons removed, and/or having higher pollution with higher zinc additives.)

of course, at the end of the day it is up to the user/consumer to decide/judge. most importantly, BE AWARE of what one is pouring into their cars, what additives/contents does what and so forth.

for my case, without technicalities, i still choose liqui moly over torco for my main iswara car because i like the engine smoothness over torco's performance in the higher rev ranges. and hey, more protection towards the car (in a sense) and environment knowing that liqui moly mos2 semi syn as the API donut while torco tr5 doesnt?

thinking of switching over to liqui moly (or other brand of oils) for the nissan sentra too since it's not like im gonna race with it and i BARELY drive it myself (although when i do i friggin like to floor it rofl)
i believe it comes with a cat con too and perhaps it is wiser to use a lower zinc additive engine oil in the long run eh?

Rather interesting reply from Torco and a lot will think, wow.. definitely good stuff. Then again, if you do a little research into why API has been reducing the amount of zinc in the engine oil, you will understand why Torco can't get the API donut.

Check this link to know why API standards have been reducing the zinc content.

Viscosity does not translate into protection. Film strength provides the protection from shearing but there is no film strength indicator. Viscosity just means the fluids resistances to flow which is another meaning for being thick or thin. A lower viscosity number does not always mean lower protection.

you do realize that most torco racing oils are in xw20/xw30 right? aka low viscosity? and when it comes to racing, i dont think people will be driving "gentleMANLY" right?

your english aside, the thing with engine oils or just general facts is that, they aren't based on "feeling". oil's film strength (and additives, among others) is what determines the protection of your engine. NOT viscosity. your "FEELINGS" of driving gentlemanly or not in a car has nothing to do with science.
in other words, you've totally missed sleepwalker's points btw.

then try tesco semi syn engine oil lor. API rated also. i know many using it with no problems.

thanks for the advice.

wise words. so what oil u recommend ?

still hoping for someone to explain those numbers...

I see. It seems that some myvi users prefer to use 10w40. Hi-Rev oil, anyone used before? How was it?

?

checking the service package that perodua has on their website.
http://www.perodua.com.my/service/service-...age/myvi-1300cc
shows that , they recommend a SL rated oil. since the price is only 75 bucks, i would assume its mineral .

in eu, most of their semi syns are mostly still sl rated. according to http://www.bobistheoilguy.com/forums/ubbth...&Number=1594976
sl or sm rated doesnt effect the performance persay, they just reduce the amount of zddp ( anti wear addictives) to comply with emissions standards.( think about euro3, euro4 compliance and standards)
I suspect in your case, u feel better performance because of the switch from mineral oils ( which in this country is generally thicker) to semi syns( which are thinner oils) it has nothing to do with the api rating.

so your argument is invalid.

5W30. It has to be either Fully Synthetic or Semi Synthetic. Any 5W30 made from Mineral is potentially damaging to your engine so I would advise not using it.

On the other hand, 10w30 made from Mineral is perfectly fine.

I see. You've got good knowledge about engine lubricants. So, stick up with 5W30 better? is Catrol 10W40 magnatec a good oil for myvi leh? anyone still using them?

API SN is for semi-synthetic or for mineral? or it just depends, guys?

API SM or API SN? I know SN is newer, but putting API SM oil will not cause harm right?

i am using this "CI-4 categories precede SM or SL"
