Let's do a simple comparison of the few products mentioned here (similar products of grade XW-40). We list down two key parameters to determine the quality of engine oils scientifically, not through hearsay in layman terms.

TBN (Total Base Number, the higher the number the longer it lasts)
1. Mobil1 Advanced Full Synthetic 0W-40 - 12.6 mgKOH/g
2. Millers CFS 5W-40 NT - 10.11 mgKOH/g
3. Fosser Premium VS 5W-40 - 10.0 mgKOH/g
4. Millers EE LONGLIFE 5W-40 - 7.44 mgKOH/g

VI (Viscosity Index, The higher the value, usually it dictates the better the performance in the test)
1. Mobil1 Advanced Full Synthetic 0W-40 - 186
2. Millers CFS 5W-40 NT - 177
3. Fosser Premium VS 5W-40 - 171
4. Millers EE LONGLIFE 5W-40 - 170

Of course there are many other critical scientific parameters (such as Cold Cranking Viscosity, NOACK Volatility Test, etc.) to determine the quality of the oils, but they are not available from the official published data for comparison. I happened to see both Millers products have CCV of 6,600, which is actually a very poor result from a fully synthetic product.

On a side note, Millers EE LONGLIFE 5w40 offers a TBN figure of 7.44 only, which is indeed a worrying number. Personally i won't use it for OCI of 10,000km for traffic conditions in Malaysia. Perhaps it should be drained at 7,000km at best.

Let's go back to pricing:
1. Mobil1 Advanced Full Synthetic 0W-40 - RM152/4 quarts
2. Fosser Premium VS 5W-40 - RM200/4 litres (with free labour + oil filter)
3. Millers EE LONGLIFE 5W-40 - RM240/4 litres (with free labour + oil filter) (Price quoted from TDUEnthusiast)
4. Millers CFS 5W-40 NT - RM352/4 litres (Price quoted from Lowyat Garage Sales)

Just my 2 cents. Hope it helps...

Yup.. I happened to notice that the EE LongLife's TBN seems to be quite low, and much lower than its semi synthetic brother (EE Semi Synthetic) which has 10. I usually change the oil by date though, and so far after owning this car for 4 years+ I've only racked up about 36k KM of mileage.

any good tyre shop to recommend at ampang area? last time kena conned with chamber screw stuff like that, dun wish to go back to that shop again

been having weird petrol like smell or engine oil smell idk which at the front passenger seat, seems like engine oil leaking at the front so i suspect the smell is from there. yesterday leaking quite a lot until floor also have, zordaq charge me rm100 for labour and the rocket gasket cover seal, reasonable? i believe their proton parts are cheaper than the other workshop, the boss say is original from proton

Gasket Rocker Cover PW811643
RM78.87

If RM100 include labour, its a good deal.

Hi guys, just want to try my luck and ask if anyone knows when the new Persona 2016 model will be released ? Thanks.

If you don't mind. Mahkota Cheras got one

I think our car definitely need camber screw? Been reject this to ALL tyre shop, EVERY tyre shop I went sure will ask camber screw. Some even adjusted the alignment lari so much that my reverse will get into b another side and almost bang the gate when the steering is straight... Return back they will say no camber mar, it's like that...
Meantime another few cars in house never got asked for camber screw... Makes me wonder is camber really necessary?

finally i witness myself how the water leak into car. this happened yesterday raining.
some say the door weather shied has to redo with new adhesive.

Don't think so... I think you haven't found a good and honest shop. I believe that our car's alignment should be done easily considering that the toe for all four wheels can be adjusted without requiring any parts to be changed. When my car was fitted with camber bolts last time (also kena con), they just adjusted the reading to be 0 with the car in the air. But this was on the pretext that the tyres will wear out faster on the outer edge, which doesn't make sense since a more positive camber will make it worse I think, in addition to having bad/aggressive toe adjustments.

My current all round camber readings are - 1.xx deg + and the shop I go to still can make it straight. The toe reading is also affected by the camber, but as far as I can see, as long as they can get the toe adjustment right, the car will go straight. When I first switched to sports suspension, the camber reading was -2 deg left and -3 deg right. The car's alignment still could be done correctly without any adjustments to the camber.

bro...forgotten to ask u. is ur car equipped with GC and the VS that i've given to u?

I am using the VS only for now. Took out the GC already.

Theoretically all aftermarket HID are illegal.
Only the factory fitted ones (which come with original car) are considered road legal.

ive made bad decision
