Please let me know whether it is safe to use octane 90 petrol for my car instead of using octane 95?
I don't have the user manual so I don't know what is the fuel that my car was designed to use.
Is there a benefit of using octane 95 over 90?

Ask the dealer what octane is reccomended. In the U.S. Most cars are designed to run on 87 octane. There is NO benefit in running higher octane gas unless your car is designed to run it.

Examples of higher octane requirements would be high output N/A engines like the 1ZZGE engine or any turbocharged engine.
