Everyone with oil temp issues

IDZRVIT:

Please note that Nissan's warranty period is for 5 years or 60,000 miles for powetrain issues (and that is a limited warranty at that). Most of the folks here are concerned about high temps leading to engine longevity issues.

Does anyone on this list want to foot the cost of a full rebuild at 100,000 miles or less because the oil gets to damn hot? Highly doubtful.

Timing belts, spark plugs and oil changes are maintenance. Engine rebuilds are not...and that's why I won't buy a 370Z until a factory certified oil cooler is made available at a reasonable cost...

Nissan is only interested in making the engine last to the end of the warranty period. Then they are off the hook. Many here and myself included want to keep the car longer then the "limited" warranty. The comment about the oil consumption issue of the '06 is a valid point. No, I do not trust the engineers just bacause they work for Nissan. They are building a product to come in below a certain price and must make concessions. I don't want one of these concessions to be my engine which may be out of warranty by the time the high oil temps finally kill it. Nissan has advertised this car as a sports car and show it running hard. They need to step up and protect the engine with a cooler.

I am one of those '06 oil consumption guys. I can attest to the attitude, and what it took to get any action. They want to make profits!

Just as a point of reference, other cars in the class (or similar class) do not have this problem. You can take a base model Corvette and flog it at the track all day and the oil temp will never go over 230. Similarly an RX-8 or STi will run without issue in the same conditions.

The hypocrisy is that the car can't handle what it is marketed as. Nissan knew this which is why the press cars were fitted with oil coolers, I bet the production protoype's were as well. Somewhere in Nissan an engineering bean counter (probably against their better judgment) cut the part to meet a budget as they calculated that 90% of the people were never going to experience a problem. I think they shot themselves in the foot as the problem is now affecting sales, ironically most of the buyers that are holding off would never experience a problem but they read about it and get scared.

Your loss (and everyone else who has expressed the same sentiment). Don't cut your nose off to spite your face. ..... In the grand scheme of things this may boil down to a bad batch of senders. I've been unable to push my car beyond 245 degrees despite trying really hard. There is a lot of inconsistant reporting on this issue. Regardless, I mounted a cooler (for a whopping $270) and will never have to worry about this again, real or imagined.... I can barely get it to 200 degrees now...

The though did cross my mind, what if this was a bad batch of sending units.............. but them equiping all the magazine test cars with coolers does make you raise an eyebrow...

Yeah..The numbers have been so varied, even under, what would appear to be, similar ambient temps and conditions. Makes one wonder...

Well a big part of that variance, aside from weather, is probably driving habits. Even when we try, it's hard to accurately convey exactly how we're driving, in terms of time spent at what RPMs under what kind of throttle, etc. Unless we all started doing datalogs of our daily driving to go with the temp reporting, that's going to account for a lot of the unknown factor.

I hit 240 degree oil temps with the cruise control set at 70mph in 6th gear for 20 minutes.

How was the weather? You're in AZ, so I assume 'hot'. Around here even on an 85-90 degree day, a highway cruise locked at 90 in 7th (my 7 is a bit higher than your 6, but the speed diff is going to make up the revs and then some I think), I can pretty much run a straight line down the highway indefinitely and never see over about 225-230. I'd still be much happier if it stayed lower than that under such undemanding conditions though
