the guy was prob just more curious about the state of the oil than anything else...

 

,,,

 

honestly if it did i didnt notice it at all, so im gona go ahead and say no
i dont plan on using it again


easy buddy i dont think anyone was out to insult you

ive seen/read/heard about many different ways to break in an engine, what to do, what not to do, baby it, or beat the stuffing out of it. im not saying your way is wrong.

however...

its impossible to determine how well/long an engine will perform solely by it's breakin period, it just plays a factor. maintenance/inspection is another major factor.

i am very curious to see what an oil analysis looks like after you put on 15k though. if your not planning on using castrol, what other syns are you looking at using instead? if your having trouble deciding on an oil to use, take a look at this thread too

https://my350z.com/forum/engine-and-drivetrain/258663-vq-oil-analysis-and-info.html

most (if not all) of the UOAs done in that thread are on DEs i believe. i noticed the averages with certain oils in the HR and DE are closely comparable. so, if i was lost in the woods about what oil to go with, i'd start lookin at that thread

good luck

 

What is your problem? Oh yea your 15. I simply want the results kept at the top for reference!

 

He was just joking around, and he's 32. He has over 15 years experince is what he meant to say. I have to agree with him as for the time's to change the oil, not only do you get check the consistancy of particulate, you also continue to get rid of break in material. Which keeps your tolerances tighter.

Don't misunderstand us after the break in period, by all means change only every 3000. It just helps a lot if you keep clean oil in the car beforehand.

 

For sure.

 

Second Mobil1 report.. speaks for itself...

I already put castrol 0w30 in, still putting miles on it. I expect improved results, but who knows what will happen... The numbers have to go back up at some point.

I believe you can see some wear beginning (Tin). Thats from bearings if I'm not mistaken. Everything else has been pretty much consistent. The aluminum dropped again, which I am happy to see.

So which oil do you suggest?

Not really sure what I am looking at.

 

+1, hitting 2k on my 07 soon and want my first oil change at 2k. What do you recommend for first oil change?

 

From my experiences: Of all the oil reports I've done, Mobil1 5w30 has been the best so far, and I do recommend using it for your first oil change until you find something you like better. I expect the reports form the German Castrol 0w30 to be better.

 

Have you tried Amsoil 0w-30? Or was all the other samples Mobil1

 

+1 on Mobil 5w30. Works good for me

 

Tried reading most of the thread, looks great. Thanks a lot for helping the community with this project.

Have you had a chance to try Royal Purple? It just seems like the most popular on some other forums. But granted the other forums haven't done many UOAs so who knows? Granted it's a few bucks more, but I'm sure we'd all be willing to spend an extra $10 per oil change is there was a measurable difference.

Also, have you ever used Sea-Foam? I use it about once a year... Half bottle in with a full tank of gas, half bottle in with the oil about 500 miles before the next change. You wouldn't be able to send it in for a UOA but it might clean up the following interval?

 

I dont remember where I read it but I remember Royal Purple not being worth the additional money because it broke down alot quicker and didnt provide a noticeable difference in protection amongst other syns like Amsoil, Mobil 1, and Castrol Syntec. So for the $$$ I think your good to go with those.

 

I am sending in my next oil analysis today. Though I only have 2.2 k miles on the oil, it will still give us an idea of what the oil looks like when switching to synthetic early in a VQHR engine's life. (I switched out to synthetic at 1250.) I ended up changing the oil a bit earlier because one it's winter time here in Colorado, so I don't get to drive my Z as much. If there is snow or rain, she stays in the garage. And two, because I had a High Performance Driving Event coming up, I wanted to change out the oil for the trip there and of course for the event. I will go ahead and post the new results when I get them. Which should be pretty quick. They e-mailed me their results last within 4 days of me sending off the oil. We just have to remember, my engine only has around 6.8k miles on it, so I imagine their will be a high Silicon and Iron content present.

 

 

Do you have any plan on using Motul synthetic?

All my changes have been synthetic, see first post for more details... My first oil change I used royal purple and were possibly the worst results of all my tests thus far. I don't think it was because I used a synthetic early in the engines live. What kind of oil did you use?

Good question, no. I'm not going to use Motul after seeing how similar the UOA's were between the DE and HR. The Royal Purple UOA for my HR wasn't great, and I've heard the DE's get similar results from using Royal Purple as well. I've also heard that Motul wasn't very good for the DE's, so I mine as well not even give it a chance.

 

The same oil I used earlier in the thread. Because of Resolutes oil analysis thread, I have stuck with AMSOIL TSO 2000 0W-30 for this current oil sample. The new oil I put in is what AMSOIL replaced the TSO 2000 0W-30 series with what they call their SSO Series. Or Signature series oil. It should perform just as well or better than the TSO. I guess I will find out when I change my oil again in the next few months. But again, because my engine still has low miles, lots of break in material will still be present.

 

Hey Sibble,

I love what you've done with your oil analysis. It is very helpful. This thead has sparked interest in myself to try some new stuff so last night I just picked up 4 quarts of Lucas Synthetic 5w-30 and 1 quart of the Lucas Synthetic oil stabilizer and am very anxious to see how it will perform. I may send it off to get an analysis and give a heads up of the results if anyones interested.
