Guys, on the topic of the condition based maintenance for the Civic turbo variants, no matter how well you drive you will never be able to match the engine oil life span with the actual distance travelled because there is a time element which is used to calculate the intervals. Not just the condition of the oil itself.
This is my experience based on my BMW and my car is only 7 months old. I've tried going in full Eco Pro mode (which is more saving than even the Civic Eco mode because it has energy de-generation) and yet my servicing interval is 8,000km less 2K from the stated 10K.
This was 1 of the reasons why I didn't want to get the Civic Turbo when I learnt that it was condition based servicing.
But it's not really a bad thing to service your car faster. For BMW turbos, there is a common issue with oil sludge build-up which is why most BMW owners are happy to service every 6-7K. But for us, we have 100% free servicing for 5 years or 150,000km. This oil sludge could be an issue with the Civic turbos as well.
But I also think that if ure going to drive slowly and as gently as possible to try and increase your engine oil life span, then u're never going to enjoy your turbo. Might as well have bought the 1.8S.
So my advise is just drive normally and enjoy the turbo. Don't worry too much about the servicing intervals. It wont be a huge 'loss' for you in the long run.
For this kind of system, the engine oil is mainly monitored by the engine hour method or the in built viscosity sensor (or a combination of both). Our weather and driving conditions can be the harshest on engine oil life (other than the extreme winter cold which we don't experiece). Hot and humid weather, combined with lots of start-stops and traffic jams, our bad habit of idling the car for long periods of time just for the air cond, and top it up with a relatively dustier environment, these factors are much averse to engine oil life. So we may have driven (example) 800km, but the actual engine hour could be equivalent to double of that or more. So even as you idle your car with the engine on, the engine is actually still running thus reducing the oil life despite no movements. Hence, the example given by cybermaster98 will surface. This, i just learned not too long ago, is very much unaware by most motorist.
The rule of thumb is, go for fully synthetic engine oils, (at least) service once a year or 10,000km (give and take 2000km; 15,000km - 20,000km if you use top range high mileage engine oil family together with range extended oil filters or change oil filters at half point). If you do lots of short runs (less than 10km or less than 10 minutes driving), better change your oil every 6 months. You can use semi synthetic in this case to save a bit on cost. Also, give it a good highway run at least once a week for about 15 minutes to evaporate out the water in the engine oil. Short runs can't bring the engine oil up to proper temperature.
