hi thanks for all the answers will try it =)

Thanks, will check it out at the local battery shop for this.

Hi All,

I currently driving the proton saga Iswara 2007( orange color model).

3 weeks ago, i had some issue when i drove my car. It jerks terribly when it hits 3000rpm at 2nd gear. Since its near the time for me to do my periodic maintenance, i send for maintenance. During the check up, the mechanics found out that its time to change my spark plug as it's filled with carbons deposit. At the same time, i also change the cable for the spark plug and did some maintenance here and there.

Then the mechanic asked me, what petrol i'm using. I told him I'm using Ron95 with some adjustment to the timing. He told me that my car, according to the manual, it is suppose to run on Ron 97. And when i change to Ron 95, the maintenance cost over long period will be higher as the Ron95 will effects my car performance and conditions (i think he is talking about Ron 95 is not good for the engine etc..).

He suggested i changed back to Ron 97. I did do that but the petrol price recently jsut hike up again.

So, my question is that, 1)Does using ron 95 really that bad for the engine?

I'm not sure how to compare the cost wise for different grade of fuel but basicly, 2) is it true when he says the maintenance cost will be higher and its much more worthwhile to pay for the higher fuel cost for Ron97?

Appreciate your comments.

Hi,

Hope this reference can answer your question.

http://paultan.org/2009/05/14/can-proton-c...n95-grade-fuel/

THanks. I've read the website earlier when i changed to ron 95 last year. It just that since i got this problem and the comments from the mechanics, i wasn't so convinced with the article from paultan anymore for this matter.

That's why i'm wish to gather some advice/comments from anyone else here whether they had experienced this during their maintenance and can advice based on their experience.

Hi,

FYI, I have the Iswara year 2007 and using RON95 without problems. Yes, Iswara has an old generation engine but it is not that old as not suitable to be using RON95. What you need to to have the engine properly tuned that's all.

Regards.

something wrong with ur car wiring i guess... somewhere is short circuiting.. if u lazy to find out the cause, disconnect the battery if u leave the car for few days untouched...

its not the battery problem... normal healthy battery should even last for weeks even the engine is not started...

what is engine reterder??...

can use ron95 laa.. ur mechanic sinkalan u... retard ur ignition timing a little bit more... change new sparkplugs... should be no problem... make sure ur engine din makan engine oil can adi...

another sin ka lan forman
mine 91 saga out of tune carb and untouch timing since left production line and have must use ron 97 sticker at the fuel cap olso can run 95 and sommore 92 before but got little pinging if uphill and hot day la

Hi catacombs, thanks for your advice. However, it may still be the battery because the car was manufactured in August 2010 and sold to me in December 2010. So, during those 4-month storage period, it had only clocked 60km before I took delivery and I had only drove a further 85km thereafter. I suspect their technician did not do a proper PDI (pre-delivery inspection) and so did not manually charge up the battery sufficiently prior to the delivery of the car to me. Hence, if the battery had been "sitting idle" for 4 months or more and with not much usage after I took its delivery, its internal condition may deteriorate, not to mention that it is those cheaper lead-acid type (although is maintenance free), but not the "gel" type, which can hold the charge better and for much longer.

Anyway, now that it had been charged for 15 hours, I'll see if it will die again after a week or 2 of non-usage (if there is a chance that I may not use it). I had measured the resistance at the battery terminals (disconnected of course) and it seems to be okay with quite high resistance, although fluctuating, probably because of the immobilizer and alarm units. Should it fail again after a week of non-usage, I'll go to a battery shop to have an analysis and their opinion. I've already given up on those people at the Proton service centre. They can do nothing but only good at trying to avoid responsibilities and liabilities. Regrettably, for as long as this (bad) work attitude remains, Proton's image will never be able to be on par with its competitors, no matter how good their cars can be. Proton is able to have an edge because of price advantage. Otherwise, the name Proton would have been history. Sadly, it's not that they don't try to make good engines, but if those in their service centre are still practicing the "can't be bothered (tidak apa)" mentality, I doubt their after sales service can ever be able to satisfy their customers. Sigh.......

If upgrade to 15' rims, sure your f.c drop even more << i heard a forumer said this... is it true..??

wont affect much la...choose 15" taiwan made rims instead of local made, local made will be heavier

huhu.. i also dunno mine 15inch r taiwan made or local.. just only know the brand.. dynamic..? local huh..? hehe

hahaha i also never heard of the brand dynamic before.

Any recommended shop in Klang valley for piping? I need to fix my piping cos it's giving me the bursting sound everytime I drop gear. Just changed muffler n center bullet still the same. I suspect pipe or extractor problem.

haha......use engine power to slowing the car.......that i calling engine retarder......
