Last month due to very hot weather in Karachi I was also doing a lot of idling with ac on all the time on short trips (with the shift lever in Park position) and I was getting very low mileage for the trip like 5-8 Km/L, and an over all drop of mileage to around 10-11 Km/Liter, but now with weather less hot my car is giving low mileage like 12-14 km/Liter even on longer trips. My air vent for Hybrid battery below rear seat is clean & I recently changed oil & air filters and my car was giving good mileage after that.
Any suggestion from Aqua/Prius users
