50k miles just about... sorry. I thought i included that in the title of the post
Well, I change the oil when the car tells me to change it and the oil actually still looks pretty good...I am currently using Amsoil 5w30 signature series with a Purolator PureONE filter. I forget what I used before (I know it was at least a synthetic), but the oil service notification came on around 6k miles, but this time around it came on at around 7k.. don't think it has anything to do with the oil? if it does, then that kind of proves that Amsoil is a better oil then whatever it was I was using... lol but I believe seeing somewhere that it's only based on how it was driven/average RPMs or something.
Could someone explain to me how the car calculates when it thinks it's time to change the oil?
It's automatic btw (wish it was 6 speed manual)... and I guess in reality I'm not really driving it all that hard... I do get on it every now and then....I think there was only once ever, when I first got the car, that I was WOT to see how fast it could get up and go.
My idea of hard is jumping on the highway real quick, but then cruising all the way down at ~65mph. Guess when compared to other cars I drive, it's just easier to get up in speed which makes me think I'm driving it hard.. lol who knows. SO my re-evaluation seems to be that my driving is nothing out of the ordinary for the GTO. Now if I was doing the equivalent in my Saturn, I'd be constantly be pedal to the metal (well, pedal to the plastic). compared to the GTO where I'm maybe at half throttle-ish lol.
