Burraq pso adjacent Daewoo terminal. Been using octane 97 since 6 months in JDM 660. Never found it out of stock. Has 4-5 functional dispenser of hi octane almost anytime of day.
PSO pump adjacent malir cantt cp6. Reliable but mostly of stock. Just one or two dispenser. Used for almost an year before burraq.
Qayyumabad/karsaz pso. Sharaefaisal/University rd shell pump. Occasionally used, but found them reasonable.
In general, I prefer company operated pso or any shell pump.
