What is the fuel tank size of a 91 Civic sedan? And can anyone tell me what would be a fair fuel consumption figure for this vehicle in an automatic?
Dual carb 1.5 version
I am getting high 10s or low 11s per 100kms around town which is higher than I would expect. 200,000kms on the odo.
I also noticed that when I dont use high octane fuel I get a ticking sound when accelerating hard (pinging? or just carby noise?). I asked my old man about this (he serviced the car since new) and he said it has done this for many years running on 91 octane and is due to the aggressive timing and don't worry about it. He has adjusted the timing before and the ticking comes back soon after. He also said it has been like that for so many years if it is causing any problems we would know about it by now. The car doesn't appear to be blowing any smoke and still pulls away just like I remember it did when we purchased it.
I think it is due for a tune but I think I will run it on high octane anyway. Anyone have a view about that? The noise is more annoying than anything else.
