2005 Mazda Rx8 Rotary
Valvoline Conventional High Milage 5W20
Sorry for the lack of baseline data, but I hadn't heard of oil analysis until a couple of months ago. I've had my RX8 for 7 years now, have tried to keep it well maintained, and have had very few issues with it. Now, at 137,000 miles I'm wondering if I'm better off keeping this vehicle or will I be better off trading it in for a used vehicle with a warranty, etc. If the costs of maintaining my RX8 won't be too high, I'd love to keep it, but if the oil indicates serious impending issues ahead I'd love to know.
Blackstone seems to indicate some alarm at the chrome, iron, and lead content, but I thought I'd crowdsource just how alarmed I should be about this and hopefully learn a lot more about oil analysis in the process.
Thanks for any guidance and expertise!
