According to the service book manual. If you often do cold start and drive less than 10 km (short distance drive, a lot of stop and start or 8km), you should change the engine oil every 5000km. I change my engine oil every 5000km (5W-40 or 5W-30 depend on seasons)

Wow brenny, thinking deep i see.

I find that if i fill up after 1 week, using almost half the tank (20L), it works out to be less fuel efficient than refilling at the end of 2 weeks (around 40L)

Any explanation for that?

Thanks tiny. Which engine oil would you recommend for the FD1? The service book manual says everything OEM honda :P

without getting into specifics my guess is that it would depend on quite a few things like how often you'd use your air con..where your driving (ie freeway...start stop) and have you got the same amount weight in the car at all times (except for fuel) and if your going by your fuel gauge as a halfway point ?? cause its never half hahah i find it goes down quicker the lower it gets on mine anyway

but wouldnt 91 decrease the performance? like against ulitmate and v-power. Plus, i think that its better on the engine if you fill up with better petrol. And btw, does anyone know if its necessary to replace the engine oil on the first 5000km run in a new car?

depends on what the engines made to be run on, if the engine isn't designed to run on high octacne then it won't be able to take advantage of the benefits...the RON is just to decrease/reduces the chance of knocking or igniting under compression so it ignites at the correct time inside the chamber to create the optimum amount of power

My new Civic only can run 380kms , surprise me.
I thought it gonna be much more than that
I pump premium 98.

Do you drive a civic sport btw? and do you refuel before the light comes on or after?

I've been looking at a few fuel threads and I'm quite surprised actually. I drive reasonably well tempered with the occasional swift take off etc and so far I'm at 1/2 tank for 330km's and the car only has 700k's on the clock so fuel should still be a bit more than normal.

I always run v-power. Found it to give the best economy with the extra power/smoothness. I find vortex burns to quickly and ultimate is overpriced and inconsistent. One tank I got 600k's in my euro the next tank 520k's and I drove it the same along them same roads. But that's just from my experience

Mine one is Civc Vti with 17" rims, do you think the 17" rims affect the fuel consumption?

I used to pump before the light up. is it any different, i'm a new noob

[tinymoon]

I usually refuel whenever the cheapest fuel possible during a week, if not i will refuel before the light comes on. A lot people and mechanics would say it is good for engine
The width and size of rim affect the fuel consumption but not much to notice.

yeah there are all sorts of theories. usually if you always fill up when the tank is at half way you will maximise the overall fuel economy.

but if you always run to fuel light this wont be bad if you do it all the time. it's usually not recommended as people will say the tank has particles that build up and float at the top of the fuel, if you always fill it, they stay at the top, if you run it low the particles get burnt and cause damage. but i always wonder where the particles come from, and if say you have always ran to empty you must burn them before they become dangerous.

but meh, who knows.

i always run 98 octane, usually ultimate, or otherwise the mobil or caltex versions as they are near me. it is proven better to run bp ultimate than the normal 95 or 91 fuels, not sure how ultimate compares to the other companies fuel but i've never had any issues with it and done high k's
