I have a d15b with a si tranny in my 93 hatch, its pretty much stock engine wise except for my intake, Im getting about 350 kms per tank with 94 octane gas from sunoco, oil and tranny fliud is fresh, Should I be getting more km out of this little motor?

chris_si98

why the **** are you using 94 octane?

switch to 87

you should be getting way more than that.
Quit using 94 octane (waste of money).
When was the last time you did a FULL tune-up?
What are you driving habits like?
Which ecu are you using?

Pointless..in my y7 on regular I get 540 per tank and thats a mix of of mostly roads part highway

kwasley

but you shift at 2000 rpm and drive 80 on the highway, i cant blame you though after getting those speeding tickets

hahaha i have a built motor and i get 350 on spirted driving.

450 on normal driving.

Quit using 94octane its unnessicary for the motor you have.
Like ZeeMAAN said Full Tune up is likely in order.

and if he's using a stock p28 with a jdm d15b his fuel/ignition maps are going to be off.
And zyepher knows all about using the wrong ecu and how it effects mileage/power.

As said before....94 is a waste to use on a d15. Some engines actually run better on lower octane and get better fuel mileage....

I use 89 octane and i get 600-650km on my d15b. My engine is a whole different story tho lol

he's talking about a different subject sto0pid

Its mostly city driving, Im pretty sure I have a p28, I usually shift around 3000rpm, somtimes 3500-4000 when I want to make a little noise,

Why should I not use higher octane fuel? I dont mind the extra few cents per litre, plus it burns cleaner. If anything its better for the motor, no?

no, that engine only requires regular unleaded (87 octane).
If you have a jdm d15b you need the p08 program (not the p28), so i would suggest chipping your ecu and getting the proper program put on it (pm me).
A tune-up would be a good idea also.

my d15b2 gets over 600 each tank. my engine also has low k's though so maybe thats why.
