I asked for ESTER oil, they put syntetic?? Does this void the warranty. I am taking it back! I have 2 miles on it. What should I ask for?

 

I'm not too sure about the warranty, but the car will be fine. Most of the users of this site use full synthetic, as do I.

I wouldn't worry about it.

 

Putting in synthetic oil DOES NOT void your warranty. I've used synthetic in my Z since I bought it, 3 years ago... Still using to this day.

 

You guys have 350's, right? Chances are pretty good you're not aware of the issues with the VQ37VHR, ester oils, overheating, etc.

OP - why would you get an oil change on a new car with just 2 miles on it? The car comes with ester based oil, maybe they thought you didn't want ester oil and were requesting it be changed out to the next best thing - a synthetic.

 

I think he means he has 2 miles on the oil change.

 

It does not void your warranty but need to take it back ASAP. Its going to start running real hot. The 370 was made to use ester oil and thats it.

 

if synthetic is the "next best thing" shouldnt it be fine

 

Look at it this way - the dealer can't do anything that would void your warranty. They are the official representatives of Nissan working on your car. If they break something, they have to fix it. If they do something wrong, they have to make it right.

Unless you go in there requesting something that would void your warranty, i.e. insist that they use the wrong oil, that would be the only way they couldn't be held responsible. I'm certain they would warn you of that beforehand.

 

when I bought my Z I was never told anything about ester oil... I have been using synthetic this whole time... should I be using ester? I just think if it was that big of a deal my dealer would of told me...

 

In CA, I can't imagine overheating being much of an issue. I'm sure dealers aren't making a big deal about it anyway. For 99% of drivers, they never experience the problem and if they do, they don't know it. As the oil gets hot, engine power is restricted automatically. It was first noticed by guys on the track driving the car hard.

 

Dog sledding isn't always in season up here... we get extreme heat too in the summer. In fact all my track days so far have been hot, humid and between 25-30 degrees CELCIUS! So ya we can overheat lol.

Just to add to Nissan dealerships mistakes, I went to buy my MTF fluid at the dealership. I asked for the proper weight GL-4, they told me they don't have any GL-4 and they use GL-5 on all their cars including 350's. I had my owner's manual with me and pointed out that it specifically says to use a GL-4 in the manual transmission... maybe it's GL-5 and GL-4 safe but they couldn't supply any data sheets on it at all.

 

There are some fluids that are compatible with both GL-4 and GL-5 but don't have the harmful additives in normal GL-5 that cause a problem with our transmissions. Royal Purple is one for example.

 

They "claim" that they just "coded" it wrong! THey claim they put ester oil in it!! How do I check? Would another dealer know?

 

mrrrkva, your gonna be fine. Relax, take a deep breath. Nissan using Ester or Synthetic isn't going to make much of a difference. Just as DavesZ said, only people tracking the car hard have even seen a difference. Go out and drive your car and stop worrying.

 

It would probably take some expensive tests to determine. Don't sweat it - one cycle of synthetic oil isn't going to kill your engine.

 

Any quality synthetic oil will offer the same level of protection as the esther oil from Nissan. The OEM oil is not required for the VQ37, we have numerous customers running AMSOIL, Redline, Castrol Edge, Mobil 1, etc and they are not having oil temp problems. The engine is prone to oil temp issues when ran hard we've seen problems and an oil cooler is the solution to that, not oil type.

 

Have used Motul full synthetic since purchasing my G37 in 08. No issues.
