Interesting to hear you guys fill up every 2k maybe mazda uk are very cautious....typical brits eh!:)

WHO guys fill WHAT up every 2k?

And.....you're welcome.

spoke to some rx8 owners earlier and said they checked oil every 2k and nto the 500 miles i was advised

For me, I've resolved to check it as often as I can. And when I see that it has dropped below half way on the high and low mark on the dip stick, I put in a half a quart.

Yes, check at least every 500, but it really doesn't use much - when mine was new it was a touch overfull, so I didn't add a drop for 3000 miles, I was waiting for it to get to the 'low' mark on the dipstick, so I could see how much it took to fill....
It never reached it, it went in for an oil change. (And came back a little 'overfull' again!)
