READ THIS IF you use Redline oil and Puralator
 

So I just picked up my 370 today and went to my friend's mechanic shop that he runs now. He's a honest fellow that knows a lot, and he questioned me about why I got the redline and puralator. Naturally I just replied I saw members on the forum using it and liking the results; also cause of AK370's great DIY thread.
Basically the Zinc in 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.

Being that there are a ton of other oil threads out there with actual oil wear results, I would be hesitant to take any anecdotal advice of a mechanic who seems to not have done a lot of work on 370Zs (just getting this from the other cars you mentioned).

I've used Redline and the Nissan Ester Oil and had Blackstone analyze both after about 3K miles of driving (one at 15K miles and the other at 18K). Redline oil does equally as well as the Ester Oil in terms of wear, and not sure how it would cause more damage to the stock catalytic converter.

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!!!

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.
However you said, 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 :twocents:

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.

i pretty much got the same exact stuff you got kaiser. non-racing redline synthetic. perhaps my mechanic was reading up on the racing version, but i'll have to do some of my own reading. i'm not doubting you, i know you do your homework, that's why i went with the redline. he didn't say the oil doesn't work, but he did argue that the zinc (possibly in both or only in redline racing) will eat away at the catalytic converter.
this is all talking long-term damage.
as for what oil filter he put in, i honestly wish i could tell you the name, but i forgot. i just know that it had a little circular ring inside, that the puralator didn't. i'll probably stick with him on that.
just throwing it out there, this is my daily driver now but i will be taking it to the track here and there, when i can. i probably won't be going crazy with bolt-ons. the way i see it, go big or go home (boost).

:iagree: You should probably have the oil tested BEFORE you take advice from "some mechanic" on this very complicated fluid. There are many companies that do oil testing. Their results can confirm or deny any short-comings of any oil on the market.

He said the oil has Zinc in it and it will burn out the Cats? Would'nt you have to be burning the oil for that to happen??? But whatever, I have no Cats anymore so no worries for me LOL

I'm with you on this one...

I've used the Purolator Pure 1 filters on all of my cars. I've seen a few filtration comparison tests that show the K&N, FRAM, Moblie1 and OEM (in my car is was a Honda filter) all not being as effective as the Pure1. Not only for filtration but also affect in oil pressure.

I'll try to dig up the test and post the info...

^ I'm interested to see them.

Exactly.

Check out Bob Is The Oil Guy some time and you will see that the Purolator Pure 1 is about as good as you can get.

Either he didn't buy the Pure 1, or everyone else is wrong and this one mechanic is right.

Take a look here for example:

Pure 1 - Google Search

I think your mech was feeding you a line of BS.

Regarding the oil filters, Purolater makes more than one type of oil filter that will work the the Z. the mechanic may be referring to the "regular" Purolator oil filters as being "****" - the Purolator filter that has been highly recommended here for the Z is the Purolator PureONE filter.

Red-line Oil consistently performs very well in VQ37s as per bob the oil guy posts of the many oil analysis on that site. I don't know where your mechanic drew his information, but I don't believe a word of it and take it with a grain of salt.

Time for a new mechanic.. The 500hp should of been a sign..

lol mechanics talk sh!t on anything that you didn't pick up from their own recommendation...
