Beware of LM which alot of semi syn oil selling at fully syn price.

u mean u the new molygen?

I always check oil levels after service each service. Was full, 5k later notice drop in level with Castrol. With Shell no drop in level.

Recommended for my engine is 0/5W-30. As such I do not wish to change. My oil change is 10k as recommended by engine manufacturer, did not feel any drop in engine performance or quantity with Shell. Mine is a 1.6 turbo.

For sure there are better brands,but found difference minimal, don't think its worth the extra cost IMO! Maybe good if one constantly redlines the engine,which I don't!

If not mistaken is molygen and toptec

Im using hx7 now on my myvi.. feel a bit better compare with perodua oil semy syn oil n also liqui molly semi syn.. can feel less vibration on my engine. my car running with almost 100k mileage now

what is the SAE grade of the Perodua semi syn oil?
If you change from xW30 to xW40, definitely can feel less vibration, regardless of brand.

Really? I never knew that.

Can anyone enlighten me on the change interval of Shell Helix High Mileage 15W-50 engine oil - 5,000, 8,000 or 10,000 km?

Follow your car's maintenance schedule.

Shell Helix Ultra with pureplus tech is one of the best oils out there.

Used by Ferrari and Camaros

Most engine oils with the same specifications (same weight, synthetic type) performs the same.

Check if API-SN, then followed by Manufacturer's approval.

Like ACEA, ILSAC or Manufacturer spec (Eg:Mercedes) fill.

If two different brands of oil withe same rating, like

Shell Helix Ultra 5w40 or Mobil 1 5w40.

Both should perform similar. Even there is any difference, it will be no more than 1%

More precisely said, should be lower noise instead of vibration..

Saw in another thread, You sold your SF?

The additive is different. and that's what made them better. LM ceratec, MoS2 those are the additive which will smothen your ride by miles. Pouring the engine oil out from the bottle itself differs. They are greyish dark color engine oil and some are green in color.

You very observant, yes the santa fe was let go since family situation no longer require another car to be maintained. Hope the new owner knows how to maintain it. Sometime still see it on the road and have a weird tinge of nostalgia.

Additive is different but the base makeup of these additives are the same. They all buy from a handful of suppliers


Pouring engine oil from the bottle would never tell you how good an engine oil is. Color does not make any oil perform differently, that itself is an additive to make the color

Hope new owner willing to invest in real HDEO.
Everytime I see ppl pour pcmo into SF/Starex I would facepalm...

Neh, i don't think that the person even know what HDEO actually meant....but not my problem anymore....hope the owner knows how to rein in the accelerator pedal to avoid too much oil consumption.

Technically, PCMO also fine for light duty diesel engines, as long as use euro 5 diesel. Looking at the specs of API and ACEA, the wear margin is actually a little bit tighter compared to HDEO, so technically "should" protect the engine a little better than HDEO.

But i'm planning on pouring HDEO into my petrol engine next year anyway Thinking of the UHP....

Aiya you missed the boat liao. 12.12 sale just ended. You could have bought UHP at discounted price.
By the way, What is your new ride?

what is UHP?

Missed 12/12 sale, you can still give me Christmas sale, later boxing day sale, then year end sale, then new year sale, then CNY sale....

Oh well, i'm not i a real hurry, only will need to use it 1 year later. I'm driving a mazda, still under free service period.

It is one of the HDEO product range that chemistry sells.
