Either the 04 is different or I've got a remarkably unthirsty engine. 2,300 miles on the clock (including a healthy amount of VTEC) and it is STILL showing 5Xs :thinker: I can only assume that it is suddenly going to start guzzling oil........

Mine's been like that Mark.
I did have to put 300ml in at around 2000 or 2500 miles. That all came in one go too. No usage for ages. 300ml needed. No usage since.

Oil consumption is directly related to VTEC. YOu're not driving hard enough :D

I'm not convinced about this! The only time I've had to fill the oil up on mine (300ml) was after 400 miles of motorway driving and very little vtec, yet normally I :rev: all over the place and it doesn't seem to use any. :confused:

I had to put about 500ml in my MY04 at around 3000 miles. Used the Hellfords 10W40 in the orangey bottle.

Covered 3600'ish now and seem to have no less oil :)

Once you get to 9,000 you can go synthetic. Honda recommend 10W30 (at least for the 03 and before - is 04 the same?)

Obtaining a good synthetic 10W30 is not easy. However, I found a willing supplier of Redline 10W30 which the US guys seem to like - details are on the for sale and wanted area in a thread I posted.

The mineral oil is to allow just enough wear for the the engine to bed in and loosen up, and it soaks into the peciliar material the block is made of too. In fact the Redline synthetic oil warns you NOT to use it for the first 3,000 miles of a new engine's life!
