This was a big reason I ended up not buying one. I was getting uneasy from the first couple reviews and reading that the car and driver car had oil and diff coolers installed. Knowing that someday I wanted to go to a driver's school, I was thinking this was going to be a problem for me and for people that were going to track the car. I was also worried about what installing an aftermarket oil cooler would do to my warranty.

It seems from reading through this post it's even effecting people who just go out for a spirited drive. Come July and August I think there maybe a lot of unhappy owners.

Other than this issue though, I absolutely fell in love with the car.

Really? and you are sure about this via what solid factual information?

People are reaching 250+ on daily "spirited" driving in 75 degree weather in a span of 5 whopping minutes. In the west coast, ambient temp reaches above 100 easy in the summer and couple that to prolonged stop and go socal traffic. How are you so sure about your statement? People are having worries and it's barely spring.

I was regularly getting it to 260 today on 2 minute auto-X runs, once returned to idle the temperature would drop. Ambient temperature was 45 degrees. 10-15 minute cool down between runs.

here's a couple that are available if you register in AZ !

At 10:30am I took a drive from Sylmar to the 405 to 118. Got off on Topanga to PCH to Kanan RD to Mulhalland and back to Topanga . My oil temp read 225 in the canyon roads and it didn't go any higher than 225 temp. The outside was 78 degees.

how was your driving characteristic? sylmar 405, 118 are all wide open fwys with no traffic at that time on a weekend. Did you push the car thru the canyons or just cruise?

I pushed alittle saw alot of CHP I'm it's not really HOT yet but I'll still look at my oil temp I got Auto but I was using the paddle shift in Fed I was driving stop and go on the South 60 I had the car for 1 week and my oil temp read 230.

From Cincy to Columbus and back today I saw a solid 200 at 75 mph with an ambient temp of 73 F. My 335i would be at about 230 F for the same drive.

:bowrofl:

I went out for a pretty hard drive this morning (see http://www.the370z.com/nissan-370z-p...ing-drive.html) and my oil temp never went above 240. And I was driving WOT for a good bit too. Within a couple of days of bringing my car home, I put a bottle of Redline Water Wetter in my radiator. Part of me wonders if that's helping my oil temps at all. I have no baseline to compare it against though, seeing how I put it in so early. Maybe some of you guys who have been seeing oil temp problems could try it and see if you notice any difference? It's supposed to reduce coolant temps by as much as 30 degrees. It comes in a 12oz bottle and is available at any AutoZone. What I do is wait for the car to cool down, then pour it directly into the radiator. You'll want to use a battery acid filler (or siphon) to suck up 12 oz of the coolant that's already in the radiator first before pouring in the Water Wetter.

I figure it's worth a shot, and I'd be interested to see if it makes a difference for anyone.

Red Line Oil: Coolants and Others

I've thought about using Evans.

They had this same problem with the BMW N54 engines the first year. Now all of them come with an external oil cooler mounted in the passenger side fender compartment. BMW did retrofit many 2007 335i's with the cooler on a complaint by complaint basis if I recall.

^^ agreed. BMW after service and Nissan after service however isn't the same. We'll see how this unravels....should be very interesting.
