Proton persona suspension is too soft. High speed really mabuk. My old saga fl 1.3 is much better, guess i have to buy aftermarket suspension kit after my warranty ends

Engine no problem. runs like it should. just no idea this rattling coming from engine or other parts.

Maybe I'm lugging the engine? I can eliminate this problem if I always rev my car more than 2.5k and shift @ 3.5k. Vroom Vroom.

From the video I'm on a hill in gear 2. Revs are below 2k when I begin to accelerate.

is it the metal sound coming from the engine that is rattling? Ur engine noise is quite similar to mine under load

Yes correct. Its from the engine compartment.

Either its....

1. Engine pre-detonation

2. Exhaust system rattle. this user solved it by tightening his heat shield.

Go for other big proton service centre. I've heard many bad stories about cose. Cant believe they said its normal hahaha

where else got big one? AFAIK Proton CoSE is the biggest one???

Top up Rm64.25. The oil around 190, free oil syntium 800 around 120. Psst..psst..customized sunshade rm50++ only 11street.

Maybe u can try proton sungai besi and glenmarie. I've been to the sungai besi one and its not bad the staffs are friendly.

What viscosity oil they gave u? 30?
That sunshade I think MR DIY RM49 like that only... 11street still need pay shipping

Anyone knows what is the stock wheel weight for this Persona VVT?
Changing to light weight wheels can improve fuel consumption?
Will it void warranty?
Any wheel to intro?

Welcome to the club

Making the car lighter surely will improve the fuel consumption, but I don't think is obviously noticeable thou... the cost u spent on the Rim itself even it does help to improve the fuel consumption, I doubt how long it will takes to actually get the return of the investment...

Usually people change rim is for performance, upgrade tire or for the looks...

Vehicle Combination Average Speed Average mpg Weightage (per wheel)
BMW 3 Series equipped with
Original Equipment (16") Stock 38.7 22.8 42.5 pound (Baseline)
BMW 3 Series equipped with
Plus One (17") Lightweight 39.0 21.5 38.5 pound (-3pound)
BMW 3 Series equipped with
Plus One (17") Heavyweight 38.8 21.1 48.5 pound (+7pound)

1) Lightweight VS Heavyweight (10pound difference), additional 1.9% fuel economy, 1.7% in metric,
If a new set of wheels cost RM1700, you will need to spend RM100,000 in fuel to return investment, that will translate to 409,090KM odormeter at RM2.20/L/9KM, driving 225KM for 365days for 5 years to return investment

2) Noticed the OE Stock VS Lightweight Bigger tyres, although 1inch bigger and 3 pounds lighter, the fuel economy dropped 6-5.7%, from here I can conclude that the tyre low rolling resistance played a bigger role than just SIZE and WEIGHT.

Researched Concluded,
Hope that this could help wannabees like me don't be an idiot.

a lot efforts u put in the research there

U can give it a try as an enhancement to the car, but don't hope too much to gain any savings from there

About tire is give and take... low resistance tire often don't give good grip while higher resistance tire is the other way round... so in the end of the day it still boils down to what u want to achieve, no right or wrong thou... some people just love to see their car got more economical than before even the money spent is not justifiable... but hey, its good for the environment atleast
