I heard theories if you off your air cond your engine overheats faster. Part of aircond is to cool engine?

Possible,in worst case scenario of a failed radiator fan....that is...if the engine is running 2 fan of which one for the aircond and one more for the radiator. Remember that the aircond condenser is in front of the radiator and whenever any of the fan runs, it sucks air through both the aircond condenser and radiator. If the radiator fan fails, switching ON the aircond can delay the engine overheating.

Nope, its just that the aircond and radiator share the same area for airflow and sometimes fan.

Yup, well said, but then if it was the reverse, meaning air con fan fail then with air con on it will overheat faster, since air con condenser will have extra heat, couple with radiator heat and only one fan running......lol

My parking is super duper open and with current weather...ouch.

Riding is better. Riders dont even sweat despite wearing jacket under the sun.
My previous office , I parked outside but I also didn't get to sweat coz aircon can get cold pretty fast.

extra milage, probably.... (assuming everything else is a constant and u dont wind ur windows down)

will it give you an extra 10km? who knows.... 10km is arbitrary
maybe right? we might not know.. sometimes i need to turn off the aircond in order to save the petrol usage, until the symbol already blinks and got not range haha!

i had once a scenario where i knew the next petrol station is 10KM and my petrol gauge is already at blinking fast red with no more indicator. this was my mistake as i did not notice the fuel gauge during start of journey. so i had to drive at a good light footed and a/c off with windows slightly down by 1cm just to gain extra mileage for us to reach the petrol station. upon reaching petrol station, i pump full and it was 39litres out of 40 litres. dont want to have that experience again. whenever my petrol left 2 bar i will straight search for a petrol station

Well, at least u can estimate how much u got left when it starts to blink. I have pushed my BLM with blinking fuel light from Gemencheh to Malim Jaya (Melaka). Purposedly ignore 5 or 6 opportunity to refuel just to see how far it can be stretched. It was at night and i drove 60kmh with aircond off.

When filling up, it can only take 32l from the claimed 40l tank. Normal fill up when it starts to blink will never go above 28l.
