Higher Idle after switching from Shell Vpower -> Mobil Ron98

[Hoppe]

I have switched from Vpower recently to Mobil/Exxon and noticed a jump in idling after that.

When I was using Vpower, idling was about 800-1000rpm but upon switching to Mobil Ron98, it has jumped up to 1500rpm (going up and down). Thinking that the ECU may be the cause.

 

BTW, I have been feeding my Suzuki Swift 1.0GL with Vpower for quite some time now (hehe...overkill but company pay, so use lah) but had to switch to Mobil after my company switched to support Mobil/Exxon instead of Shell.

 

The mileage that I have gotten for full tank seems to be the same (didn't fluctuate drastically) after the change though.

 

I will approach a workshop this weekend, but if possible will like to get some pre-information first to avoid being ripped. :P

 

Hehe, maybe that's the result of putting something too good for an old car.

most prob the ECU is self adjusting with ignition timing, etc...

does your have knock sensors?

nothing to worry about... if there no obvious knocking or vibrations...
