I'm wondering what could be reasons for a car's decrease in fuel efficiency?
Before, my car (1997 Nissan Sunny/Sentra), runs an average of 350-360 kms from full tank (around 33 liters) to almost empty.
Now, it's only running up to 320-330 kms at full tank. I noticed the decrease after I went for the regular oil/ oil filter change.
Any ideas?

1. bad traffic conditions
2. tire pressure
3. wheel alignment
4. poor driving habits (sudden starts)
5. vehicle age & maintenance (leaks, tune-ups, etc)
6. car modifications for performance (wide tires, etc)

Thanks for the responses. Sa tingin ko "poor driving habits" ang problema
Anong pala ibig sabihin ng "sudden starts"? Yun ba yung pagpatakbo agad ng kotse after ma-start, without warming up? Kase ganon usually ginagawa ko, hindi ko na pinapa-idle pagka-start ko. Andar na agad after a few seconds lang. Is this an example of poor driving habits?

Sudden starts—when the lights go green, hataw agad. Don't be heavy footed. Treat your accelerator pedal as if there's an egg underneath.
If you see a red light ahead, try to manuever the car with the slightest break or gas needed to go there. Let it cruise. Sometimes if you go to a full stop, the car needs a healthy amount of gas to move. So the trick is, slow down then if the lights turn green without you doing a full stop, the car need less gas to move.
As for the starting habit, no need to idle if your car is EFI. Drive right away. But don't go beyond 40kph during the first five minutes. Aircon should be off too. After that, you can drive faster and turn on the aircon.
And best of all, enjoy while you're at it.

It sounds like a potential headache for the unlucky ones that got their units from EV solutions PH...
