READ THIS IF you use Redline oil and Puralator

370Z Purist

Did the first oil change at 2900 with Redline 5W-30 synthetic and a K&N filter. Ever since I installed the K&N, I had second thoughts about it so I went out as soon as I could and bought a Purolator PureONE. K&N is even smaller than the stock Nissan-badged FRAM!

I noticed that whatever they fill the Z with from the factory makes more of the characteristic valvetrain ticking than after the Redline does. Another buttdyno-ish assumption is that the oil temperature seems to rise faster and stay cooler (190-210).

In any case, I had to order my Redline from the internet so I've been considering just going to Royal Purple as it's readily available and it's still a very good oil. I might stay with Redline but seeing as I plan to change the oil every six months/5000 miles I will do an oil analysis with the Redline (even though I'm only at 6699 miles after about 14 months).
