Morning dARKaNGEl,
Mobil products have been working good for me, including their lubes and petrol (Synergy F1 works best in my Persona). As for Mobil Super S 10w40, yes I've tried it and its pretty good. If you've just switch from Syntium with viscousity of 15w50, you'll immediately notice that the engine runs noisier and revvy happy upon switching to 10w40 oil. 40 weight is noticeably lighter than 50 weight oil. FC wise, pretty subjective for me as the difference is not that dramatic.
As for Castrol, I assume you're thinking of the Magnatec. I haven't personally tried it, but some said its good (maybe because of the BP DNA in it). Castrol is BP's flagship lube so it must have some of the engineering goodies dedicated to them. However, if I'm not mistaken the Magnatec is a premium mineral oil, and not a synthetic blend/ semi-synthetic lubricant.
Price wise, I believe both are priced at around RM97. Any sifus with better lube background care to give more comments?
Thanks for sharing. I think i will try out Mobil Super S this time. You say after changing it's noticeably noisier? Is that true? I read review online that says it's quieter...

Just want to share my disappointment of my persona & proton
Basically what am I going to highlight here are quality issues (again & again..)
I don’t want to write much..just list down the problem from day 1 till now (my persona only 4 months old..why got so many problem!!)
1. handbrake..can’t fully released..problem solved..
2. both front alloy rim cap came off…bought 2nd hand at tyre shop
3. nyek..nyek sounds from rear seat’s locks..problem solved..DIY
4. the famous clunking + nyek..nyek sounds...the clunking sound still persist with a bit improvement after replace insulator..
5. bad radio reception..no solution yet..get used to it already..
6. engine hard to start (sometimes) + loud sound engine (like old taxi)..going to replace the IAFM soon (only 4 months old..IAFM out already!)
7. noise when braking..problem solved..done brake service
8. faulty of volume controller at steering..problem solved..replace new switch..
9. air cond system sometimes on/off..no solution yet..
10. interior light faulty..don’t know whether circuit problem or bulb problem..going to complain at SC soon..
11. weird sound while turn down/up window (driver side)..might be power window problem.. going to complain at SC soon..
Not sure whether you guys face the same problem..or I’m just the unlucky one..
Fed-up la with proton quality…

Wow.. I can only say you're one unlucky owner.
Of all the problems you experienced, I only have the bad radio reception problem so far after near 2 months of ownership.
But i must agree that the engine sound loud from outside, especially when the air con is on but i believe it's normal for this car.
