How many miles for oil change

bradz

Is it advisable to change the oil at around 1,000 miles or we need to follow the 3,750 interval? Any insight?

I did 1k for first change, then going by normal intervals

Personally in the Zed, I'd change it at 1 thou, then every 5,000kms with an ester based synth, like Motul. Bare in mind though that Ester based oils are not desgined for long life but they do excel under high stress and heat but after 5,000km even according to Motul the oil should be changed out. for the Zed I'd go the 5w-40 in the Motul 300v range, expensive but good.

I went to the dealership to have my 1200 miles oil change this morning, and the service adviser told me not to change the oil, because the car is not fully broken in yet. He even told me that there is break in oil in it.

the oil in it from the factory is nissan ester oil...

I think they used mobil 5w30 semi synthetic. Is this gonna harm my engine?

Why 5w40 instead of 5w30 like the manual specs?

kannibul

Mobil1 makes great oil...no harm...

It's what I use in anything I care about.

It's incredible how much BS is out there relating to oil.

Let's see, Corvettes, Porches, and a bunch of other high-end autos come from the factory with 100% synthetic (and supposedly Nissan uses a synthetic blend, not a "break in oil", as its factory fill). You can switch to 100% synthetic (like Mobil 1, Amsoil, Redline, Royal Purple, Nissan's ester oil, etc.) whenever you want. You can do your first oil change as early as you want - but I'd wait at least 2K to 3K miles to get some use out of the factory fill.

And you should use the viscosity that Nissan recommends - 5W30.

If you are saying there is no such thing as a "break-in" oil then this is not accurate. It has always been for as long as SYNTHS have existed that for a new engine it is best that a natural mineral oil be used as an engines first oil for at least the first 3000 to 5000 miles rather than using a SYNTH when breaking in an engine.

The reason is entirely based in that using a SYNTH (with its extra friction-preventing additives) for break-in does not allow the kinds of internal cylinder pressures required to FULLY expand and set the rings properly against the cylinder walls. In fact even Royal Purple has a specific "Break-In" oil (and named just that BTW: Royal Purple Engine Break-In Oil ) that is a blend of natural mineral oil and SYNTH. It in essence provides the best of both worlds.

Being that Nissan Ester Oil is a natural conventional oil then in essence when the Nissan service people said that the engine had a "special break-in" oil they were technically telling the truth. They are in essence keeping the SYNTH out of the engine until after the 3750 mile "break-in" period has been met.

I offloaded the so called Break-in-Oil at 1,000 miles and stuffed the engine full of Royal Purple 5W30. This will get replaced ever 3,000 miles religiously.

Regardless of any other comments and primarily for my own personal satisfaction ( none fact based ) and for the basic rule that lubricant breaks down the moment it becomes functional.......this has been my routine, and the engine truly appreciates the care.

My only proof of this relentless process is my 12 year old pick-up truck which has 354,000 miles, 3,000 mile oil changes continue today and it runs fantastic ( it is still my daily driver ).

I Doubt I will personally ever see this Z car ever get to 50,000 miles but I enjoy the process.

Just had my first oil change at 1800 miles with Nissan Ester Oil. Then at each recommended interval thereafter.

[QUOTE=355890;163329]why are you calling out the use of the term "Break-in Oil" by using the "roll the eyes" emoticon??? It is "break-in" oil in every sense of the word since it is mineral oil and not a SYNTH....

I did my 1st oil change at 1500 miles using Mobil 1 and have noticed slightly higher oil temps since. With driving habits and weather temps being the same I find this odd. I'm going to continue to monitor the oil temps. I'm thinking of using Redline 4 my next change.

ZKindaGuy

Before you put in redline 4 why don't you try the Nissan Ester Oil as this was the original oil put in the car before you did your first oil change and see if the engine temp goes back to what it was before you put in the Mobil 1?
