Both are u wrong. Petronas 10w30 is semi but eneos 10w30 is mineral based. U can used 10w30 eneos on ur viva but highly not recommended. It recommended if ur viva > 5years. Stick to at least eneos 5w30 for ur viva, can used it until 8000km. U can used 10w30 semi from petronas. But the density is high compare to 5w30 eneos. but ok to used it. No problem. If u have any inquiry u can ask at my selling thread. I dont mind if u dont want to buy the oil but at least i happy to share the information

Yap. W = winter but 5w and 10w thickness,density , kinematic viscosity and vi is not same. Big diff.

then can used 0w50?
some part u are wrong..
W = winter, this show how well the engine is lubricate during cold start.. but it also show the density and thickness of the oil itself.

yup.. thats true.. how about 0w40 and 0w50.. can it be used to normal engine?

Petronas 0w30 can be used on Viva?

ok la.. this is what the correct one..

the thicker oil are not protecting ur engine.. it just how to solve the problem.
valve seal problem, oil decreasing too much, tappet issues and etc..

low cc engine normally like viva used w30.. either 10w30 or 5w30.. BUT not 0w30

the low the xW number , the oil is very thin.. thats mean.. DO NOT USED 0w30 on VIVA... no one in malaysia used 0w30 on their viva..

high cc engine better used 40,50 or 60 - because the engine generate more heat during running.. the number mean the engine oil operating temperature.

0w,5w,10w,15w,20w is as what u explained above but it also tell the level of the oil it selves.

if u using 0w50,0w20 on the normal and low cc engine (except hybrid car), ur car will KO faster.. aircond also sometimes cold and not (because engine also drive the aircond), more leaks.. head leaks, white smoke, SLUGGISH and etc..

ok this example ;

20w50 - for old car.. > 10years which is have white smoke (valve seal ) problem
10w30 - for low cc engine (kenari/kelisa/viva) but this car also can used 5w30..
10w40 - recommended for car > 5 years but it also can be used on new car, also can be used on old car if the user maintain to used it.
5w30 - recommended for new car
5w40 - recommended for new car which prefer performance
0w20 - hybrid car
0w50 - high performance car, new engine,good maintenance...

no need to explain. i know
u find one viva used 0w for me. with that.. u will know, car with <1000cc engine can used 0w or not.. and why prius and hybrid car need to used 0w and cannot 5w

fully synthethic confirm from group 4 or 5 right? are u sure?

Group 3 +
but the quality is SL (2001 grade) low quality .. current quality is SM at least.

API SM has higher requirements for the lubricants to meet such as superior engine performance, protection and cleanliness as compared to the requirements of API SL.mproved deposit protection, better wear protection, and better low-temperature performance over the life of the oil.
+ the engine oil is hard to turn black and can go KM and better engine protection.

hmmm.. i know what W means.. W = Winter
your knowledge is the one screwed up..

better u check at the prius manual..

but in engineering
SAE viscosity grade 0W, 5W, 10W, 15W, 20W, or 25W
Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. In everyday terms (and for fluids only), viscosity is "thickness" or "internal friction". Thus, water is "thin", having a lower viscosity, while honey is "thick", having a higher viscosity. Put simply, the less viscous the fluid is, the greater its ease of movement (fluidity)

good luck..

bro.. SAE bro.. SAE.. dont make u look stupid here..

u know W is related to viscosity is related to thickness of the oil?

on firefox.. google.. find out what SAE means.. and google again and find out viscosity mean..
dont want to gaduh2 here...

you again andy.. this is my last reply.. since u dont want to get a warn later from moderator.. if i prolong fight this...

andy andy andy.. i have a lot of viva customers..lot mean.. A LOT.. and viva forumers.. not one of them used 0w on their viva.. because they afraid to thin of oil will harm their engine due to engine oil leak and etc. maybe u can find someone for me used 0w on their viva for long time at least 5000km..

sorry matrix.. didnt mean to.. im really sorry.. didnt mean to say u stupid.. really sorry.

why dont change the oil sump gasket?
normally leak means that valve seal leak..

engine leak at oil sump it because of the gasket.. not because of the oil..normally if u have white smoke problem.. cause by valve seal leak.. sometimes they called it engine leak...

Added on July 8, 2011, 12:02 pmthe different between API SM and SL.

http://sas-origin.onstreammedia.com/origin...p/pc/index.html

choose API SM and compare with API SL and SJ..

there is other API.. but not in the software.
API SN and SG

castrol SN already..

not suitable.. used 15w40.. if eat minyak hitam also... used 20w50

betul tu.. selalu valve seal jer.. tak sampai piston ring...
guna thicker oil will not solve the problem but will reduce the problem... for the moment used 15w40 or 20w50

do u understand selalu = normally? im not saying it not caused by piston rings.

okla...

selalu valve seal je cause problem.. piston ring bukan selalu..
