but if using 10w-30, izzit the oil will easily bcome heated? bcoz the oil is thinner, n u r driving big cc cars, if long distance, the oil will heated faster rite? izzit good for our engine?

Lube technology has advanced a lot over the years, so now, even ?W-30 can withstand heat better. FYI Honda SC also uses ?W-30 oil on the new Accords (2.0 & 2.4L), according to my mechanic friend working for them.

Lighter oil actually make pumping them around the engine easier, so the power losses is reduced, and in some cases, FC may improve slightly.

Thanks for the explaination hahah....hmm.... using 20-50 now haha...lol


I see.

How do you differentiate mineral and semi syn? By reading the ?W-?? or what?

if got synthetic, its not mineral ler

You can't really tell whether an oil is mineral, semi- or fully-syn from the viscosity rating alone... maybe except those 0W-? ones, which I haven't seen any mineral ones. We need to read the label to know whether it's mineral, semi- or fully-syn.

Ohh okie =D

Thanks for the info hehee....

If your existing engine since new has been run-in more than 10K km with a specific engine oil viscosity, I'd suggest you stick to the similar one but if you wanna try a lighter one maybe to improve FC & engine responsiveness, than can try switching to the Kancil 10/30 ones or maybe to full-syn if you're already on 10/30. If there aren't any serious oil losses(say less than 250ml) after 5K km, than can continue using it.

Take note that once a specific engine has been optimumly run-in to its relative 'oil-gap' between piston/rings & engine sleeve, there's no point in goin for a lighter viscocity oil unless you do not mind the frequent top-ups within your schedule service intervals.

I see.....hmm...will try

Thx

tht one only apply to the second number rite?

if lets say using 15w-40 b4, n change to 10w-40 now, its ok rite?

as the viscocity is similar, i think its ok

Google.com and it makes you understand many things from viscosity level to what fully/semi synthetic means

Just afraid that the overwhelming amount of info may confuse more than inform!

I second dat haha

recommended for normal/semi i think 5000km... ehehehe

but im using normal mineral(5000km)... and i plus X-1r in it... normally i change before it reach 5000... around 4800+- i change it..
