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.
im use ron95 no hal......bring 9 include me in the car up hill and the acceleration is good.......4G15 summore............
