I've had my car just over a month, it's slighty over 1500 miles, I check the oil at every fuel fill and the oil hasn't dropped at all.

I don't know if it makes a difference but 90% of my running in was done on motorways. Then again it could just be down to luck.

I haven't VTEC'd it at all. I am running in as I still only have 300 miles on the clock. I have been running up to 3500 and up to 4500 very briefly a couple of times yesterday.

Mine used about 1/4 of a litre on running in and now uses nothing. At the last service in August i had it changed to Mobil One and it hasn't used a drop. My 2000MY used to use loads of Mobil One due to it bing so thin but the newer cars don't seem so bad.

Just keep an eye on it. :)

In 18000 miles I have not needed to buy any oil. It's not moved from the top since I got it.

I am not afraid of the odd VTEC either :D

Oil can be used more when the engine is cold.
