Not only that, the EO has also gone up in price from RM163 now to RM190 (17% increase), dang the Petronas 5W-30 was only launched back in Oct2021 but realise something amiss when its 5L GF6A oil is price RM163 while its Fully Syn 4L GF5 oil is priced at RM159. Maybe that is Petronas / Proton strategy all along to price it low to attract us initially before CKD / mass producing the Geely 1.5L engine. Apart from that the 1.5L engine also uses a more expensive Oil Filter & Air Filter compared to the 1.8L TGDi x70 - guess that's double whammy for new x70 owners too.

Well recently I was able to achieve 6.3L/100km on highway KL-Penang and quite impressed able to achieve lower consumption than Proton's claim. For city Drive managed to get around 6.7L/100km but I am driving 99.5% Eco mode and extremely light footed with extreme slow hill climb but will utilise maximum momentum on downhill drive and try my very best to obtain "Current Fuel Consumption" around 5L-7L/100km at flat and downhill surface. Hill clim try to get around 7L-10L/100km.

Just want to ask if anyone here have replaced their car battery? Mine finally give up just shy of 2 years of ownership. And it took the workshop almost an hour just to remove the covers including the air intake box just to replace that battery stuck to the back of the engine bay.

Seriously just to rant this design is ridiculous to make owners life difficult, now imagine if you are stuck in the middle of the road without all the necessary tools while stuffing the battery to the back of the engine is a bad idea since battery lifespan will fare worst due to heat compared to placing it closer to the front (even with that X50 battery cloth sleeve). Sigh! Trying out the Indian 'Exide' battery lets just hope it last longer.

If that is the case, you may help a lot of people by posting how to change the X50 battery easily on Youtube as what I found for both the X50 & Geely Coolray all of the it also requires removal of the Air Intake box.

Yeah that is true based on the Proton service book since we are paying a Premium for the Oil-Filter (which is more expensive than even the 1.8TGDi X70 or Honda respectively), also the regular changing of spark plugs at 40k km intervals compared to Honda 100k km, and the fuel filter & dust filter to be changed every 20k km. But the biggest difference is the increased of EO price from previous RM162.50 to RM189 while Honda 4L engine oil only stated for RM135 (but not sure if this is Fully Synthetic compared to Proton)

Sure Iridium spark plugs is the way to go but honestly I wonder if it can perform at its peak throughout the 100k km or 5 years since we know carbon will eventually build up in the combustion chamber.

For the proper EO viscosity it is partly questionable? Since the initial launch of the X50, the original available EO was the Shell 0W-20 a specification same as the Geely Coolray in Philippines or our Volvo XC40 T5 1.5L (if you consider that engine to be the same). I personally did achieve slightly better FC than the current Petronas 5W-30 as required by the Proton Book however upon checking on the Geely Coolray oil catalog it did specify both 0W-20 and 5W-40 is applicable a difference in viscosity & volume compared what Proton specify.

Actually what I meant is the combustion chamber where your cylinder, spark plugs & Injectors (for TGDi engine) are located - where carbon is a byproduct of burning and it will taint these parts eventually but probably much slower since our petrol is a good source of detergent & lubricant.

The walnut blasting you mention is for intake manifold and valves I believe when the carbon build-up is due to the returning parts of the exhaust gas through the PCV valve (and for that TGDi owners can just hope it will not happen to them or very slowly since Proton claim even at 80k km they cannot find any carbon build up in the valve).

Bro the x50 is only open for registration on 16/9/2020 how did you manage to get it that early - but my battery only lasted slightly less than 2 years at 45k km.

On the topic of servicing anyone realised the increased in servicing of these specific products:

Petronas 5W-30 EO - from RM162.50 to RM189.00 (16% increase sometime in Aug22)
Drain plug gasket - from RM3.88 to RM5.26 (28% increase sometime in 2023?)
Wheel Alignment & Balancing - from RM68 to RM98 (31% increase also recently)

What I find even more sad is that all the above are likely manufactured / serviced here in Malaysia but well there are lots of money to be had. Anyone noticed any other price increase just can't wait for the Nano Mist to increase from current RM40 to RM60 and telling us how good it is.

I am currently on my 2.5 years ownership roughly 54,000km so far so good on the engine (still smooth although I think it sounded slightly noisier compared to brand new) while the upside is that the interior still good with no noticeable rattling noises while driving normally & all still stock items apart from Car Battery. However I'm still plagued by on-off brake noises which I'm glad some got it sorted while the driver's side mirror angle & sound I guess I can live with it after so long. Of course with the worsening traffic the fuel consumption also takes a beating and I seriously wonder how often do X50 owner fills up their tank on an average 350km weekly journey.

Did anyone check out the latest servicing prices provided by Proton SC lately and some of the increases are staggering updated below. In all, the constant replacement of 20,000km oil & air filter does take a toll on the SC price and those are not cheap when compared to previous non-Geely ones.

Petronas 5W-30 EO - from RM162.50 to RM189.00 (16% increase sometime in Aug22)
Drain plug gasket - from RM3.88 to RM5.26 (35% increase sometime in 2023?)
Wheel Alignment & Balancing - from RM68 to RM127.20 (87% almost double increase also recently)

Also I did not realise SC offers the Engine Oil Flush I wonder if anyone tried it before or what brand does it uses. Surprised they did not go the extra $$$ by offering Oil & Fuel treatment.

Does anyone here felt weird that Aurobay (Volvo + Geely Powertrain) has removed its 3cyl 1.5TGDi engine while it is no longer being offered by Volvo and surely being phased out by Geely but for Proton it is putting it in every foreseeable car possible including future ones.

Currently only Proton and Geely Philippines still offering the 1.5TGDi 3 cylinder X50/Coolray while all other Geely supplied country has updated to the 4 Cyl TGDi option including Geely Cambodia that sounds kinda sad.

Not sure you did realise that the Volvo released the 1.5L 3Cyl TGDi engine since 2016 and used in the XC40 since 2017 which Geely claim their 1.5L 3CylTGDi shares 90% of the similarity. The 1.5L 4Cyl TGDi LiShen power was first used in the Geely Binyue (Coolray) in China back in 2022. (Note that this 1.5L 4Cyl TGDi has an output of 181hp / 290Nm with 5.7L/100km fuel consumption all way better compared to our 1.5L 3Cyl TGDi)

I am totally with you that there will be 0% Chance Proton will release the 4Cyl 1.5L TGDi anytime soon here which I supposed the next engine we may be getting is the Geely + Renault alliance which still far off.

Anyone felt jealous that Proton South Africa actually took back their X50 to fix the wind sound noise and was given the Proton X90 as a loan car while fixing WOW talk about foreign benefits.
