Everybody is concerned about the oil temperture,lets says "if" our cars don't come with a oil temperture gauge,will this be an issue.?I have driven alot of cars without oil temperture gauge,so even i trash the cars,i don't know their oil temperture.!

Couple days ago I got an email from Nissan USA. I was told to share it with our forum members. Here it is:

To avoid activation of this engine protection system and these reduced peak engine speeds, Nissan recommends an oil cooler be fitted to the 370Z before driving it on a race track. A Nissan Motorsports accessory oil cooler kit is available for customer purchase through authorized Nissan dealerships for race track use. The part number is 21300-SS370.

An oil cooler is not necessary for normal operation of the vehicle on public roads. The addition of an oil cooler would have raised the price of the car and potentially moved it out of the reach of some customers. Value has been a core principle of the Z car since the original 240Z and we choose to uphold this core principle by not adding additional costs that are unnecessary for normal use. For those individuals who choose to drive their vehicle on a race track, the oil cooler is available as an aftersales item.

The oil cooler is a Nissan Motorsports item and as such is sold without warranty, express or implied, unless expressly prohibited by law in which case the warranty provided is the minimum required by law. The installation of the Nissan Motorsports oil cooler does not, by itself, “void” the vehicle warranty. However any damage caused by the installation or use of this part is expressly excluded under the terms of the Nissan New Vehicle Limited warranty.

That's excellent news AK, I'm glad to see an official clarification of their stance on this issue. It's about what I expected them to say at this point, but it's still good to hear it and have it confirmed.

WELL THIS THEN SHOULD PUT TO REST ALL THOSEPEOPLE WHO HAVE A PROBLEM WITH HIGH OIL TEMPS. I THINK NISSAN'S RESPONSE IS FAIR. IF YOU HAVE A PROBLEM GO GET THE OIL COOLER, WHAT DO YOU EXPECT, YOU ALREADY HAVE A CAR THAT IS AT LEAST 95% OF THE PERFORMANCE OF A pORSCHE FOR LESS THAN HALF THE PRICE. gO SPEND YOUR BUCKS YOU TIGHT ASSES.

Ak, with that response, can we lock the thread and sticky that response?

AK, I think this is the sentence most here have been waiting/wanting to hear. Satisfactorily answers the issue for me completely. Thanks!

No, please don't lock the thread - it's the most important concern to have surfaced so far and there may still be further developments. This thread is the main area for discussion and it should remain open for new additions.

For example, I cannot understand this phrase from the Nissan statement - "...The addition of an oil cooler would have raised the price of the car and potentially moved it out of the reach of some customers..."

That is blatantly rubbish - It would probably cost Nissan $300 max to have fitted an oil cooler to the cars. If they passed that cost onto customers in the basic price of the car nobody would have noticed, but everyone would have said, "Woooo fantastic, it's got an oil cooler!"

The real reason for the ****-up is threefold -
1. they're obsessed with keeping the cost of the car down to the bare minimum
2. they're obsessed with keeping the weight of the car down to the bare minimum
3. they didn't realise the oil overheating issue was going to get as big as it has - and now they are toughing it out.

There are too many examples on this forum of people getting oil overheating on the public highway for it not to be an issue.

It's not just parts cost, it's testing cost, and warranty costs. There's no getting around the fact that a pair of flexible hoses carrying the most vital fluid in your car is less reliable than keeping it all in the block. There's also no getting around the fact that if they added it at the factory, it would have to be warrantied just like the rest of the car. They would have had to engineer brackets and fittings and sheaths and whatnot to try to bring the reliability up to par with the rest of the car, and done extensive long-term-wear simulation, etc. I have no idea how to work out what that costs in the long term in a car price. Let's say it ended up being $1000 or $1500 (not unreasonable, considering they're selling an unwarrantied and less-engineered addon cooler for $700).

Car prices are cutthroat these days, and a grand here or there on the mfg side of things isn't chump change. This is before all the percentages for various markups and taxes too.

Boy am I glad you don't work for Nissan Product Development - we'd have brakes as optional extras and they'd cost $5,000 per wheel!

We do have expensive brake options from various third parties I'm sure. They're much better than the stock ones, and most people don't need them unless they're on a track. Kinda like the oil cooling. The oil:water interface in the block is enough for most people on the streets, the cooler is the track upgrade. I agree that this isn't ideal (especially for the enthusiasts), which I've commented on before, but I can definitely see their financial angle on this. What percentage of 370Z owners do you think will ever even have (much less notice) a brief oil temp spike over 260? We're not the norm.

I with you 100% on this point. When I read the "beyond the reach" posting I really got a chuckcle out of it. As you said "rubbish".

Not necessarily with you on this point. The number of those overheating MIGHT be a bit over-exaggerated. Many of the complaints have not mentioned whether their reported temps are for PROLONGED perioids of time or just for a few minutes at a time while they sit in traffic but then temps reduce to within normal ranges once traffic starts moving again.
