Civic 2004 D-17 engine.

Using 91 RON currently

The problem in Pakistan is far more likely to be the fuel not meeting the required standards or what it purports to be rather than a problem with the engine.

If that can be somehow eliminated, then various technical issues with the engine can play a role in selecting the proper octane for the fuel that would work the best.

Then the variability in fuel can be safely eliminated.

What is the issue that you consider will be resolved by experimenting with different octane fuels?

car has 155000 km on ODO. serviced regularly, got in my hands when it was 135000.

Recently got the fuel filter changed so thought of going for 98 RON for less sulfur deposits and eliminate any forthcoming knocking issues apart from experimenting better mileage.

I get 500 km in 38 Liters from it on 91 RON.

The sulfur content is regulated no matter the octane number any way. Changing to a higher octane will help with knocking only if there is already a mechanical issue with the engine such a carbon buildup, and even then only temporarily.

what about milage

what about milage

If the engine itself is working properly, then there will be no significant difference in overall fuel consumption just by changing the octane number of the fuel.

Any one having experience with trying different RON fuels in their cars?
91 vs 95 Vs 98 ?

Yes .
Which car you drive ?

May I ask why one would wish to perform such an exercise? Cost? Performance? What type of vehicle?



This particular model is perhaps the best highway cruiser ever made by Toyota.

Yes Lexus is top car

I’m in the market for either Marx x , crown or even ls600h at the moment thinking of mark x more

 

[Signalian]

Yes .

Civic 04 ...D17

91 is very weak
unless your car Ecu has been mapped to just 91RON I’d use 98RON better performance & mileage .

Old fuel sitting around also loses RON(octane rating) avoid gas stations which are not busy

Japanese use 100RON

I have talked to people who say that car engine should be tuned to RON type for max performance. Im not sure if mine has been tuned or ECU mapped for 95 or 98 RON.

All good choices, cannot go wrong with any one of them.

The user manual will indicate what type of fuel is recommended for the particular model you have. Unless it has been modified, that would be your best bet.

Then that should be just fine.
