I recently had my first 6 month oil change on my g37 and now I have 9000 kilometers on my car (5400 miles). I should change it in another 3000km (1800 miles) but I'm about to go on a road trip of about 3000 miles return. SO I will be about 1200 miles over the recommended change time.
I am using Nissan Ester oil. Should I change the oil before I leave? the 1200 miles will be mostly highway.

Thanks

If you research Nissan Ester Oil on this site and BITOG, you'll find it does not hold up well in the G37 engine. Despite the Nissan recommendation.

If I were you, I would get that oil out of my car before my trip. And I would never put it back in.

The VVEL is hard on oil. It is summer time. Error on the side of
caution....change your oil.

I've gone 10,000 miles between changes and been FINE. but that is with Mobil1 full synthetic, not the Nissan Ester Oil.

As Cougar said, I would take the Ester Oil out and NEVER put it back in.

do you guys have a link to the forum/article about this? i google searched it and didnt really find much.
ive also read that its kinda bad to put synthetic in your engine when its less than 10000 miles, so im kinda in this pickle too. if nissan ester oil is bad for the engine and its bad to run synthetic oil short after the break in period, what oil should i use? im at 3000 miles about to hit the first milestone.

interesting stuff...

Just look through the Blackstone thread in the engine forum. There are 4-5 UOA's of the Nissan Ester oil and all show it breaking down between 3800-4000 miles.

I wouldnt run more than 4000 miles on the Nissan Ester oil.

And jujubii, I put fully synthetic oil in my car around 7500 miles. I did 2 schedule 1 oil changes with the Nissan Ester Oil and then changed it to Redline.

While it IS true that you should not put synthetic oil in a brand new engine, once you hit 3000-3500 miles (whatever the break in period is for that car) using full synthetic is totally fine. There is absolutely no reason to wait post-10k

And consequently I just switched from Mobil1 to Penzoil Ultra and really like it

Ive used Mobil 1 synthetic since I bought my car. No problems so far.

I would wait until after the trip to get the oil changed.

Except that some cars are factory filled and broken-in with synthetic oils from 0 miles. So I wouldn't turn that into an axiom quite yet.

I would also. I ran Nissan ester for 5000 miles for the first few changes in my car. Switched because I wanted something a little better for the price, but you aren't going to cause any harm to your engine with it. Even the people at blackstone believe "oil is oil" and recommended running those kinds of intervals with that oil in my car. There was still plenty of additive left, I guess the biggest problem we saw was the viscosity shearing after 3000 miles or so.

That was enough to make me want to switch brands at the next change, but I didn't go running out to my car and drain the oil that minute. The car still ran fine on it until the next regularly scheduled change.

Especially considering you'll be running all highway miles on it. This one oil change is going to have close to zero impact on the life of your engine. It's what you do regularly that counts.

I don't know of ANY cars that come pre-filled with a full synthetic oil. If there are any please share but like I said, putting a full synthetic oil in your car before it's properly broken in is a no-go
