Just wanna get to know more about engine oil.

Previously I was using Mobil Super 2000 10w-40 on my LMST.
Quite smooth for the engine.

But that was before I switched to service at Proton Edar SC due to some maintenance need to be done at SC.
Then, Petronas Syntium 800 10w-40, previously was 15w-50. But they told me that 15w-50 was replaced by 10w-40.

And now I'm thinking of switching to Shell Helix HX7 10w-40. Any advice?

hmm... I thought normal car not ngam fully syn oil?
Just wanna get some reviews on Shell Helix HX7.

Wow, there's a lot of sifus here.

Currently, I'm using ENEOS Racing Molybdenum 10W40 for my LMST, SHELL Helix HX7 E 5w30 on Persona Elegance, SHELL Helix HX7 10w40 on Saga BLM and Iswara.

It's quite hard for me to get those better oil like TORCO and MOTUL here at Sarawak.
ENEOS pun I cari everywhere baru found.

ENEOS Racing Molybdenum 10w40 on LMST, just normal lor, but in my own opinion, is better if compared to Petronas Syntium 800 10w40 from Proton SC.

For SHELL Helix HX7 E 5w30 on Persona Elegance... hmm... felt engine suddenly not so kuat after the oil change. Thinking of changing to SHELL Helix Ultra 5w40 on the next oil change.

For SHELL Helix HX7 10w40 on Saga BLM and Iswara, its ok. So far so good lor.

Thats my simple review. hehe.

One question, anyone got any opinions about the SHELL Helix HX7 E? and what's the difference between 5w30 and 5w40? 30 and 40 got what difference?
