READ THIS IF you use Redline oil and Puralator

W.O.W. 370Z

Mobil 1 was a notorious culprit of oil consumption issues with the 350z's

RCZ

I think your mechanic doesn't know what he's talking about or wanted to sell you something else. I use Redline 5w30 and I'm going to be doing an oil change with ALL redline fluids this weekend. Also, I use purolator filters

NeverBoneStck

Same here ... I use nothing but redline.. You can search tons of forums and decide if mobile 1 is good for the vq

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).

I hope your mechanic is wrong, because I've been using Redline since my 2nd oil change! Lol.

EDIT: And I have 35.8k miles on the clock.

i did some reading on what zinc does.
it will help with the motor break-in but zinc is like poison to the catalytic converter. it's fine if you're running test pipes and you probably wouldn't notice damage given that our cars are 2 years old at the latest, even with 20k miles. It's long term damage.

As for the purolator pure one filter that i got. its the PL14610, same one in kaiser's diy.
realistically, i'll finish off the redline and use the pure1 for the next oil change but after that i'm going royal purple and a suggested oil filter.

i'd have it no other way than to hear people's honest opinions, just to get a perspective on things, but i'm going to stay with my mechanic's advice on certain things. i consider him a good friend that a lot of people, including myself, entrust with their cars completely.

on a side note, he's rebuilding his 04 cobra, and throwing a meth kit, and should be pushing close to 700whp.
just hearing that makes me feel like my 370 is another 140hp honda. haha o well, im happy with my z. hoping for an amuse kit and tt setup in the future.
hope everyone is enjoying their z's

ZDDP is a common additive to increase pressure resistance in oils. It has been tied to killing cats, although the kind of cat-killing this does is much worse on a car that consumes a lot of oil (namely rebuilt, low tolerance motors, not OEM equipment).

Either way, if you plan to TT in the future, it won't matter. You'll just be running nice fat test pipes instead.

so basically you're saying the zinc in the redline won't do anything to our stock cats. sounds good to me. i assume it won't matter on HFC as well?

Every mechanic knows everything. I believe in test results, not the preference of a mechanic.

Data results should provide balance to decisions/choices. It's a good thing to put the question out to the forum because you will gather a bunch of opinion and data as well. Be prepared however, to hear what the majority of insight's can provide. A single mechanic can not provide the same level of experience that numerous people can ….thus the goodness of the forum

I run test pipes, Redline oil for engine and transmission fluids and after 40k miles and 2 years of running track sessions my car runs exceptionally well.

Just my opinion above…sorry about the soap box

Its tough to really know who you can and cannot trust in this matter, what I can tell you is that most mechanics are idiots and have no clue what they are talking about. You need to do the research yourself and drum up conclusions with actual facts and tests. The redline fluid and purolator filter has been proven with facts and oil analysis. I'm a service advisor at a VW dealer and get alot of people coming in with broken cars because they followed what their mechanic said or their mechanic screwed something up and won't own up to it. We can make a separate business fixing what other mechanics screw up that's how bad it is. I had this one guy come in because his tranny didn't shift one of our techs pulled the trans fluid out and it wasn't even the correct fluid. I called up the shop that installed the tranny and told them they didn't even put the right fluid in there and they just said well the box says it's good for that type of vehicle and then hung up... Perfect example.

I agree with 370z purist ( not about the cats). I am not an auto mechanic but have worked on heavy AC centrifugal machines and screw machines. we perform 50 or more oil analisys every year on differant oils
and what seems common is that all oil have zink in differant amount depending on the brand. I looked up Mobile 1 oil on their web and their
MSDS sheet indicates that Mobile 1 also contains Zink, so is the mechanic saying that redline contains more zink and will damage converter faster then Mobile 1

so what filter do you guys use with synthetic....anyone try the royal purple filter yet?

kellyefields

I have one installed on my car right now. I went with a larger one than recommended but it works just fine. I plan to cut it open when I change it in a couple of months. I will post my results then.

Gazan37

^Nice interested to see the results. I have a purelator pure1 on there now with mobil 1 synthetic....no complaints as of yet and i drive it pretty hard.
