So good advice for myself. Never drive when tired, rushing, worried or send your car to wash to dodgy car washers.
Anyhoo. I finally managed to get my act together and calculate how much mileage the rush does. It was RM0.216 per km. Can you believe that. For 458 km (that is to and fro from Uni to kampung from Monday to Friday and weekend driving). Not bad at all. If you consider 8L/100Km. The merc cost me RM 140 per week and that was with the cheaper cost fuel. Nowadays it cost me RM100 per week with the Rush.
I have also used a few tips for driving with the intent to save on fuel. I was told by Couz Eccentric that one should drive at RPMs lower than 3000. Preferably 2000. I found this to work magically. Furthermore, I personally found out that it is cheaper to avoid rush hour traffic. Slow moving traffic guzzles gas without getting you nowhere. Same as if you were waiting for someone with your engines on. Lastly always look two or three cars ahead. Remove your foot from the fuel pedal, when you see the cars ahead slowing down, ease into a slow glide. Do not stop abruptly. Do not rush to traffic lights. It is safer and cheaper to ease to stop than to quickly accelerate to make that green light.
Anyhoo I summarised these TIPS from a website by a Daviddj
Tip A: Avoid Rush Hour Traffic! Which I found out as well.
Tip B: Keep your RPMs under 3000. Rapid Acceleration wastes gas. Slow and steady acceleration keeps your money in your pocket. You will still end up at the same top speed but less is spent.
Tip C: From Papa John: Regular oil changes will help your gas mileage as friction is reduced with cleaner oil. Maintaining tire air pressure will extend the life of your tire. Better tyre more efficient fuel consumption.
