how many miles for the 1st oil change?
 

i usually followed the owners manual for the first oil change
but i read a couple posts saying to do it after 20 miles...
dont use synthetic oil...and so on
so i was just wondering how you guys do it? :icon17:

I would follow the manual if you want to keep the car for many years.

1200 miles on the factory oil, then switching it for Royal Purple. I might even do it at 500 miles to get a majority of the metal shavings out.

That's what I will be doing.

3750

What are the thoughts on Synthetic oils? I've seen brands that inclde service like BMW basically suggest 10K mile service intervals. Are they sacrificing long term durability (out of warranty) for short term $ savings?

+1 EXACTLY what I'm going to be doing.

Royal Purple FTW!

I was told the same!

Go to the engine oil ^!

Royal Purple IS synthetic oil. Probably the most popular pick outside of Mobil 1.

I'm against changing to synthetic so soon. Reason being that the regular oil will help get everything worn and seated quicker than synthetic will. Regular oil is better for the break-in period.

1250 is when i changed it before and was told too.
and used regular oil once and on the next oil change at 3750 i changed to synthetic mobil 1. lol

1200 on dino oil then Redline Synthetic at 3750 :cool:

I'd switch to synthetic at 3750, then do changes at 5-6K mile intervals after that. I don't think a change at 1200 is necessary, but it certainly can't hurt.

^^^ LOL! You need to join a car club, man! You got a lot of questions that could simply be answered by hanging out with experienced car guys! :D

Synthetic Oil life is about 5K-6K miles. On some cars it's closer to 10K. If you race a lot, then you should change it every 1K miles although I know a lot of people that go until 3K. However, even light street racing wouldn't constitute changing it that early. People who run their cars at the track, hot lap, and/or frequent 120+MPH should change their oil often.

I used to race a STOCK LS1 car and won against many modded cars because I replaced the oil after EVERY night of racing. :) There is a method to the madness.

Based on the responses, I will probably change my original plan. Seems like the consensus is to keep the factory oil until 1250, then change it at 3750, and then use synthetic oil after that.

Royal Purple

royal purple is possibly the worst 'full' synthetic made
its not even a full synthetic...only partial http://www.comprevac.com/products/su...ossref6_03.pdf

its flash point is absolutely terrible compare to other higher priced oils
if you drive your car hard your oil will become nearly water, trust me ive raced road courses for a couple years and used it a few times

Quote from Aaron Lail of Tru dyno spots
"I had some independant tests ran on RP, Mobile 1, and Castrol syntec.

RP was the worst and actually had microscopic metal contaminents from brand new oil! Mobile 1 and syntec came in very close to each other.

I once had a small 4cyl turbo engine running Mobile 1 that had the drain plug come out going down the road somewhere. The engine oil light came on, pulled over to check and it was completely out of oil! Put a new plug in with 4 more quarts of Mobile 1 and never had another problem. That engine is still running today! "



Redline is a good oil
But Eneos, amsoil, and motul are the best you can buy
Enoes---->the oil is polarized which adheres to metal engine components under weight transfer conditions.

How about Motul? Anyone have any experience with them?

Interesting... I didn't know about those. +1 Rep

Can you define that?

3,000 :driving:

define? as in specify?

quoted because it doesnt need to be at the bottom of the page :hello:

I was wondering about Eneos as well. Never heard of them, and I didn't know Motul made engine oil either.

5K miles with synthetic is a safe interval for daily driving, but can likely go longer. You can get an oil analysis to see how long the oil will properly perform. http://www.blackstone-labs.com/

On the 350Z, I've used primarily Motul and Mobil1, but from the oil analysis threads on my350Z, Motul is not a very good oil, well at least for the VQ.

had microscopic metal contaminents < what are they talking about?

all i can say is precisely what it says...
as in the oil is not exactly pure

I have many friends that swear by RP... But I have a few friends that say they don't care much for it.

Personally, after working for GM for a little bit, I've found that Mobile1 is pretty trust worthy. Although, I've never PERSONALLY used RP. I do, however, use Mobile1 in my Solstice. Seems. I've never put anything else in it though.

LOL that's why i'm on here. I will join one soon but for now I like your answers LOL.

I guess when I get my 370z, stick with mobile 1 synthetic or redline. How much does redline costs?

start editing your posts.... no need to post one after another.. oh ya.. mobile 1 FTW

Generally speaking, Nissan has not recommended synthetic oil (at least it didn’t in the 350…I haven’t look at my owner’s manual to see if it still says it’s not recommended). I can tell you, however, that I’ve never heard of anyone having problems because they used or didn’t use synthetic.

Personally, on a brand new car/engine, I change the oil somewhere between the first 25-50 miles (or at least as soon as I can get it done)…and then I would change it at least as often as every 3 months/3,000 miles thereafter (I do it every 1,500 miles/6 weeks for a vehicle I autocross).<o></o>

I believe that if you change your oil/filter on both a frequent and regular basis, then the most of the benefit of synthetic oil goes away.

BTW...Mobil1 used to be the best but they changed their formulation a while ago and is not as good as it once was; Amsoil still uses the better formulation (not sure where RP rates in that mix).

Might want to check this article out:

Interesting article...I wonder how Amsoil would have done???

I suspect Amsoil wasn't tested because it's not as widely available as most brands.

oil threads are funny
