Basically the redline oil will deteriorate the stock catalytic converter and shouldn't really be used unless you're running some serious mods or have racing headers, or driving your **** hard all the time. I know everyone wants the best for our 370 and I'm no different, but the general consensus is that it's a waste unless you fall into the said category.
With the Puralator oil filter, he said that it's cheap **** and don't use it. He showed me that inside it is missing (i forgot what it was called already) but it's like this little circular thing inside. He then showed me one that does have it and installed it, and told me to just return the Puralator if I can. The circular thing inside regulates oil pressure, and without it, you can ultimately blow the motor by not having the adequate oil pressure.
He then said, stick to Mobil1. He puts it in his 520hp Cobra, his client's Lambo, 911 Turbos specifically only want Mobil1 in their cars.
As for the remaining 7 bottles of Redline, I'll probably use it again for the next oil change if I don't end up selling it but afterwards, I'll just stick to Mobil1. I honestly didn't feel a difference with the new oil, and my car was at 3000 miles when I got the change. It never had a oil change prior and the oil was dirty.
So just helping the community out.

Hi,
I believe you're confusing yourself with the TWO DIFFERENT kind of oil redline sells .
a.
Redline Synthetic Oil for regular cars and trucks. This oil is formulated for regular everyday cars. This is what you want to use on your Z. DO NOT use racing oil in the Z!!!

Most popular oil for modern road cars and light trucks, as specified for most late-model BMW, General Motors, and Nissan vehicles

b.
Redline Synthetic RACING oil . This Is the serious "holy sh*t" oil that will allow your
race car to
redline all day long and withstand temparature that your regular car will never see or tolerate in it's lifetime.

That is also a true statement because ANY synthetic oil can be seen as a waste if you just drive your Z as a daily driver. But I like to put decent oil in my Z because I DO couple of track days a year. So, for me switching back and forth (regular dino oil vs synthetic) will be a pain. Hence I use the synthetic all year around. If you will never attend a track and drive pretty much like everyone on the road, you can just put regular oil in your car and save tons of money. However, I will say this, putting synthetic oil WILL extend the life of your engine in the long run (regardless of WHAT oil you choose). Just my

I wouldn't say one synthetic is better than the other. It's a personal preference. If I had a GTR, i'd only put mobil 1 since Nissan recommends it. Since Nissan wanted us to use ester with the VQ, I went with Redline REGULAR synthetic oil (my personal prefence). About 32,000 miles this week on the Z and running stronger than the day I bought it (knock on wood. That's about 28,000+ miles on the Redline oil!)
What filter did you end up using it? The purolator pure1 is supposedly better than K&N which is much expansive. I haven't heard any bad reviews about Purolator pure 1. The only filter may be better (I'm just assuming) is WIX.
