I did a search on synthetic oil for the RX-8 and actually went through a dozen or so pages in that dino vs. synthetic thread. After all the reading, I'm still clueless.

I always go to a local Valvoline Instant Oil Change joint for all oil changes on my former Eclipse GS-T. I used Durablend on that car. My 2 week-old RX-8 just turned 9,000 miles and I want to get an oil change now. This will be the first oil change under my ownership. I just want to know whether there's anyone else on this board that uses the same oil for his/her 8. I went to Valvoline.com and the website recommended SynPower.

So, should I go ahead and get SynPower? Or should I stick with dino oil? How about the Durablend?

How often should I change the oil if I decide to go with SynPower? I used to stretch the mileage out to 4,500-5,000 on my Eclipse. It was still running strong, with no problems whatsoever, at 83,500 miles when I traded it in.

Thanks in advance for all answers, advice. No flames, please, as I did a search before posting this newbie question.

 

One more question: Can I use SynPower year-round? I'm from MA.

 

it doesnt really matter, if the *brand name here* works for you, then just use it.

I would prefer 5w30 when cold, you're in MA, about the same weather as NYC.

for summer, 10w30 is ok.

 

Jim Downing's rotary race cars all ran Valvoline Synthetic. Go ahead and use it.

 

Thanks nycgps & rotarygod.

SynPower it is.
