[QUOTE="AArnie, post: 327287, member: 4446"] Well, I just topped the oil level up again. Just over a week ago (1000mls +/-) I added 300ml, today it's back to where it was again. I've checked the spark plugs and they are all clean. (in case it's significant) I also asked at a local-ish dealership today and was told the following. FJRs can use upto 500ml per 1000mls, and the type of oil will make a difference. If synthetic oil is used the the engine can "suffer" from Bore Glaze: especially if lots of motorway miles are done. This inturn can increase the oil consumption. If I use a cheap non-synthetic oil, then if I have glazed bores then the symptoms may ease. I currently run either silkolene Comp 4 or Pro 4 (cannot recall which it is - the tin's in the garage and i'm not.) - as recommended by the silkolene website. I've heard of this [bore Glazing] being the case during a run-in period for a new engine - the manuals normally state that the full rev rang should be used (upto certain levels), but after 30K Miles. Next step I guess would be to check for oil in the header pipes, but i'm not sure it "ticks" too much - there is some noise but not like the sound bites on the web - at least i don't think so. Any thoughts? [/QUOTE]
