Hello BITOG! I've been on this site for quite some time but don't really put my two cents in due to lack of true knowledge. I've done as much research as possible about my question but would like to poll you guys for a second opinion. Here's my deal: I've recently purchased a 2000 Honda S2000 with 100K well cared for the miles on it. The previous owner mostly look the car to Honda for oil changes (looks like bulk) and a PCX filter for a majority of it's life. Being a older gentlemen I'd like to believe he didn't beat on it much due to lack of any noticeable oil consumption. I will be doing all the oil changes and due to the Autozone Mobil 1 AFE sale have a substantial stock of 0W30. My concern with the high rev limit of this particular car and the from what I've read sheer instability of M1 AFE worries me. The lack of anti wear additives worries me also but I'm no expert and would like some opinions if the oil should or shouldn't be used in this application. Currently running Edge 10W30 Gold Bottle and all seems well. Would a high mileage oil with a higer HTHS work better for this particular situation? Thanks for any input!
