Drive from terengganu to kl last night. I felt that my fuel consumption is higher compared to normal. Managed to clock only 350km for a full tank 95 compared to previous around 450 for highway drive. Even need to refuel halfway. Speed maintain around 140kmh. EO is liquimoly semi 10/40. First time using this EO and first time using semi. Might be the eo not suitable?
Persona SV manual 2014 mileage 78k

What oil you used previously, and did you overfill engine oil this round? May I know also your average speed for this particular trip?

Previous using shell helix ultra 5w/40. Not sure overfill or not cos never check. Speed average 140kmh. The oil now reaching 7k km. Possible this is the cause? Eo become too thin make it not efficient when cruising around 4k-4.5k rpm? One more thing, I also change the fuel filter last month.

Seems like a sensor~

my engine has leaking issue for the 3rd time within a year...already send to zordaq 3x already...the latest one engine look no leak after monitoring for 1 month...entering 2nd month its leak again..

any idea what is the other possible of leak apart from gasket seal cover & oil seal?

got check whether pcv valve ok?

If your engine oil level is at full level or sightly higher, this might be warranted situation.

Your previous oil is fully synthetic, thus by theory should be more fuel efficient (but not wallet efficient unless you can get it cheap from Tesco). Changing to semi going to takes time for you to adapt into semi punya slight increase in FC.

I change my EO usually at 5k mark, so really cannot comment on 7k EO viscosity, buy theoretically it should thin down and provide more fuel efficiency at the cost of less friction protection because reduced capability of EO to form oil film.

Anyway try look into your engine oil level will you? I still believer of with MOS2 coating, we can do away with 75% dipstick level of EO in persona.

Something i forgot to ask. Your tyre size will affect FC also. So did you change to a new profile of tyre?

Lol. Yes. Aesthetically minimalist and the best part is, no need to drill on fender. Just install the bottom screw on fender screw hole.

Bought it on eBay, but accessory shop don't know how to install, asked me to find mudguard shop.

Sorry to hear that bro. Hopefully your mechanic can catch the leaking place & cause.

@The_FQ400 bro's question is the one I would ask also.

so far didnt check that part...will check later...

Any link I can refer to?

Search for "quick release bumper latch" in eBay will do.

One of them is this:

You still need to drill on bumper to fix in the cap though.

Guys , why my car alarm beeping sound when I lock / unlock the car become silent after driving in the rain ? Is it possible that the moisture damage the system ? Or wiring loose ? How to bring back the beeping ?

Aiks new thread tak perasan pula.

Hmm going for my 90k km service soon 3.5 years of ownership

Still thinking whether to use 5w30 or 5w40 this time.
Suprisingly 5w30 is slightly cheaper for this case.

Did you manage to get it installed? I need it for my bumper too.

Hi sifus,

Usually the brake fluid is change every how much km?

2 years or 30k km for optimal maintenance. This is because brake fluid very quick to absorb moisture. Usually I can feel braking response slower after 2nd year, after bleed and replace can feel immediate braking power restored.

guys , i can feel the car is choking especially when i driving at low speed in town or stucked in traffic jam . what cause this ? just done engine tuning and i gt my spark plug , fuel filter and air filter change at proton service center . odo is currently 60k++ , 3 years old car

Tried press and hold both buttons of remote control for 5 secs?
Could be your honk wiring rosak? I got mine damaged (wire sheath exposed) in previous accident and didn't realise it until my air cond guy opens up front bumper to access condenser. Not saying that it's the cause, just would like to highlight how often mechanics or accident repair workshop overlook it.


Hi Bro, the picture in post #156 is my B-Line Chiffon Green Nana. XD


Would agree to that. I bleed mine every 25,000km though. I clocked almost 5000km per month.


Throttle body clean? Got check on that tak? Last time i got wiring problem causing throttle body cannot open fully. Manual transmission here though.

Not sure if it's cleaned or not... But the proton sa told me that engine tuning include the throttle body cleaning....
