But for Malaysian morning weather and temperature, does the cold viscosity rating makes much much different in terms of cold start?

just done 15k service at Sec51A. they have option to choose Caltex or Petronas EO.
Caltex EO same price as petrol station. they out of stock for FS so use back Semi.

no appointment, 9.30am reach, 10.30am done. my boot hard to open with remote issue solved. brake pedal got sound when pressed also solved.

small workshop but you can go jalan jalan see they work on your car. i always like this because i can provide my direct input to the technician on issues.

maybe next to caltex service center.

ya maybe.

150++. lube 104. workmanship 30+. no recommend X1R oso

Lube 104, Oil Filter Rm 10 ~ 15,

eh? i tot workmanship edy rm60?

Hap Hap holiday everyone

Not much difference. Minimal in fact.

However if you do a lot of cold start (ie. highlands, very early morning start, etc), its always safer to use a thinner viscosity.

IMO (can't confirm since it can be debated), while at operating temperature, both will be the same at 30 viscosity, during cold start, 5W will be at 5 while 10W will be thicker. My earlier understanding is cold start at our weather, 5W and 10W will be same thickness. After a few read and master posts all over, I comes to believe 5W will stay 5W during our weather cold start while 10W will be at 10W at the cold start.

5W has extra capabilities of REMAINING at same FLUIDITY at freezing temperature vs the 10W. So my new conclusion is that even at our weather cold start, 5W will start thinner than 10W. More addictives is needed tho...in order to lower the viscosity thus as mentioned before, the bad only happens if lube is overused.

Friend suggested to use 5w30 for new car compare to 10w40. Thinner is better he said

BKTTT bila?

Tunggu Sang Gajah and CK to decide. Any day is ok with me except Monday & Thursday
Mana BKT TT 1st?

5W or 10W ONLY matter for cold start in our weather. Currently I strongly believe cold start matters the most due to most wear on engine comes from there. Since I never overuse my lube (changed at 5K), the extra addictives needed to bring down the viscosity never got sheared to the stage of high viscosity during cold start, the thinner cold start fluidity helps more than 10W. Those who like extended usage of lube, then 10W might be better coz less addictives was used, less viscosity changes once the lube are sheared.

As for the 30 vs 40 weight. 30 is good for economical and city drive. Thinner is indeed better for everyday drive. I used 30 for all my vehicles except for campro BECOZ proton recommend min. of 40 for it. Probably due to campro being a high rev engine where most torque comes in at later stage, 40 might be a better engine wear protection due to its capability of withstanding higher temp. So if you drive high rev and speed A LOT and MOST OF TIME, actually 40 will be a better choice.

For most modern car, 30 is more than sufficient. Campro engine not very modern....if you really compare with most branded car makers. The newer campro engine with CPS and above all goes for 30 liao. I believe due to their better cooling system kuah....

That's from far what I know too. My friend said that 30 and 40 is the same for engine wear and tear protection. That's why I
And, campro recommended is minimum of w40 not w30?? Too lazy to read the user's manual. HAHA

Recommended is actually 20W-50 in the manual .

But min. listed is 40, so play safe, go for 40 for balanced performance. 50 is really outdated. No one uses 50 unless its an old car where the gap between the piston and wall has gotten bigger due to wear. Of course those racing kaki with extreme constant high temp....might need it. Our PE campro got abandon liao since new CPS and aboves goes for 30 liao as a default lube.

Kenny friend is not wrong in saying 30 and 40 got the same wear. It does at normal everyday driving and mid-range speed temp (below 140 kuah)...Its only at high constant speed...that 40 makes a difference vs 30 in wear as its thicker lube can still go further when thin....while 30 thinner lube will shear to a stage it might render inefficient causing engine to lose power, etc. However this should only occurs if you always runs at constant high speed. At low to medium-high speed with occasional high speed, 30 same wear rate.

Cavino, pardon if I wasn't paying any attention, from your saying, you mentioned old car (maybe) might need a higher number, 50? What if I have a non-IAFM Persona, 5 years old, what number would you recommend? I want to change the lube ASAP.

That's by far what I know. Thinner EO will contribute to FC saving too. Since I don't always go high speed, 30 is ok.


What's your mileage now? w40 should be ok by far.

soon 88k.

5 years old not old car lar.......unless you very high mileage like 150K ~ 200K km used liao...

Old cars something like 10 years above. If well maintained, don't even need to change lube since our 40 already thick enuf.

Added on December 24, 2012, 3:48 pmMy well maintained Cities still using stock 30 weight at 100K mileage, 7 years. No issue.

Normally you only need to consider increasing weight ONLY if you got at least the symptom of makan minyak after high mileage (ie. 130K above). No leaking, not issue with engine, just makan minyak.....then try increase weight BUT usually only at recommendation of mechanic after all checks turns out nothing wrong. Then try new weight got makan minyak...still got, then not weight problem.
