Thanks GTO for clarifying that. I went through numerous threads on the rear spoilers, on this forum as well as others and was more or less getting to the same conclusion. I am still curious to know if I can only fit exhaust headers in place of the manifold. I haven't found any concrete answer yet.
Meanwhile, at the last tank fill, I again got a little more than 16kmpl. I am going to religiously monitor and report the FE figures to find out what exactly has helped move it from 13 to 16.
These are a few things I am thinking of trying next:
1. Use of a fuel additive recommended by my auto parts vendor. It claims to clean the injectors and improve the performance.
2. Use of engine flush: Using semi-synthetic oil has improved the FE quite a bit. I am thinking of going further with an engine flush and hope the FE ups further. Any feedback from anyone who has tried this on his/her Santro would be welcome.
I have already crossed 67K on the odo. On checking the owner's manual I found these are the things which are supposed to be replaced after 60K:
Engine Oil and Oil Filter: The engine oil and oil filter are being regularly changed, so it's not a worry.
Engine Coolant: I have so far had no issues with the cooling of the engine. There's been no leakage and no drop in the levels. In fact I have to consciously check the coolant level every two months. Would replacing the coolant at this point serve any purpose?
Brake Oil: Again, I have never had any leakage of brake oil nor any other symptoms to indicate it may be nearing its age.
Air Cleaner Element: I am assuming it's the air filter. If it's only the air filter, it was replaced about four months back. I shall make it a point to check and replace it if necessary the next time I visit the garage.
Spark Plug: What can tell me if this needs replacement? Also the mechanic I usually go to is quite knowledgeable and I can usually trust him to do a good job. Will he be able to replace the spark plugs? Go for stock variety or something else?
Manual Transmission Oil: The gear shifts are as smooth as when the car was brand new (I fortunately got to drive it when it was brand new), so I am thinking the tranny oil doesn't need to be replaced yet. However if at all it has to be, what are the options? Again, is there any semi/fully synthetic oil available for the tranny? Will it increase the performance?
Fuel Filter: Had it inspected around four months back and it was good. Again, the pickup and acceleration of the car have been fairly consistent and linear. There's been no sudden drops in fuel supply. So I am assuming the filter is still strong.
Any recommendations or checks to see if any of the above items really need a replacement?
