I recently brought my 2004 6s in for an oil change as well as some minor warranty work. The dealership calls to tell me what was going on as far as the warranty stuff and then mentions the oil change, the mechanics found that there was only 2 quarts of oil in the car when I brought it in! I have to admit that I am not fanatical about changing my oil every 3000 miles, I generally go to 6000 - 7000 miles as that used to be the norm. I have had Mustangs, Acuras, Hondas and now a Mazda, this is they only car I have had/heard of that will eat 4 quarts of oil (without a leak) in less than 8000 miles (I went 7600 miles this time). I have no oil on my garage floor so there is no leak as far as I know, my mechanic has been doing my work for 20+ years so I don't think he is the problem. Is this engine that hard on the oil? I don't think the even rotary engine in the RX-8 would be that hard on oil, but I am probably wrong as I am not in the know on the tech stuff. Thanks in advance for any replys I may receive. JimC
