[1.3 Gs, 1996] Maintenance Query & General Question About Corolla

[corollafan]

Hi folks,

I have a doubt regarding my toyota corolla on its efficiency.

About my corolla

Its a 1.3 Corolla GS (1332CC)

Here is the efficiency report which I have maintained since I bought my car, the year to date is nothing but the sum of all the quantity, miles done till date. There is a 3 week gap in jan-feb when I went on holiday.

I would like to know whether my corolla is performing at the right level when it comes to petrol efficiency. I bought my car in Nov'06 and the mileage then was 54000.

Also, another question I am buying this additive to add in when I fill in petrol since it claims to do something good. Problem is there are 2 versions of it, one for cars with injectors and one for cars with carburetor. I do not know what does my car have, hence will any corolla owner tell me whether I am doing good or not.
