:iagree: cruising at 2000 RPM feels like I'm lugging the engine. Normal cruising for me is more like 2800 to 3000 RPM.

Eick!!! :eek: Aggressive driving? I never even went above 5k. How was this aggressive? OMG I love that picture btw! I swear that's the dood from office space beating the copy machine!

Who drives their car around like that...seriously?

He's out to prove a point that oil temps rise with high engine RPM's, like that's some kind of revelation...

Short of sticking the car on a track, oil temps won't be an issue. Oil starts having issue around 350-400F - the bearings in the engine start to potentailly have issues at or above 300F. That's why Nissan put in a "limp mode" when it hits 260 and again with it hits 280 - not to protect the oil - but to protect the main bearings.

Yep.

He wasn't at high rpms. 4k is low for the engine. It should not be doing that.

4K is high for most engines. Just because the redline has changed, doesn't change the thermal charactoristics of how burning gasoline creates heat.

Consider this, an engine running at 4000 RPM is moving 90MPH down the road. That's a lot of airflow through the engine compartment.

Now, run your engine at 4000 RPM and go 10MPH. Guess what, your engine heats up faster. OMG! Panic ensues, people put up posts about how hot the engine is, and put up youtube videos.

Also, consider that people on here are griping about 220F oil. Seriously? That's nothing to be concerned over. That's just over halfway before oil would have any issues, and over 80F from any potential damage to your bearings.

Go stand in a freezer, then go stand outside. That's an approximation of the difference in temperature that is....and there's still another 100F to go before the oil is in any danger.

Honestly, if Nissan started their oil temp guage at 180F, and had it run up to 350F, and left everything alone, there would be less panic over this - people would be griping about how their oil never gets warm - lol...

:iagree:

Sometimes, this guy. But only when I'm trying to make a video showing oil temps. :p Or driving to the airport or sometimes when Im going to the movies or merging onto freeways or passing a semi-trucks... Kannibul is the slug in Z events /giggle. *gets in front of Kannibul* /beep beep

Some people at the track tend to race 4k and lower. :icon14: But they never win. We rescued them though, guess they got lost when they were out buying groceries and ended up accidently on the track in a car that looked like it belonged there.

I think it's a great video showing concern about the oil temperature.

The car wasn't even pushed over 5K RPM and the temp got that high. Even at constance 4K RPM it shouldn't be a problem.

I took a 997 Turbo on track (yes, different car), went around 10 laps; and the oil temp was... 90 Degree (194 Fahrenheit). And I could even put my hand on the intakes.

Yes, it's two different car, but my point is, cruising at 4K RPM shouldn't have oil up to 220 Fahrenheit.

Sure, I drive around with my car at 4K all the time. Seriously, your attempt at proving a point is laughable.

What's your gas mileage with 4K driving? 8MPG?

I guess you didn't read my post.

I redline my car at every take off and use my throttle liberally to express my displeasure with slow moving traffic, and my oil temps rarely hit 220F.

I tried for an hour on the street to get my car into limp mode. Didn't happen.


You'd think that this engine, being in the Infinity G37 for the past two years...oil temp issues would have come up and have been blown into headline news on CNN or some shi.. -But no, it hasn't, because it's not an issue.

If it worries you that bad, buy an oil cooler and put it on. Just don't bi.ch about it when Nissan denies your warranty claim if it causes an issue...

4k rpms is low for that engine and I will say it again 4k is low. I ran my HR at 4k and saw temps get no higher than 210 on my gauge in 105 degree temps.

He was at 240+ with 4k rpms.

Exactly. It won't get that high. When will people admit there is a problem with the car? LOL

Wrong. It has been a big issue on the G37 forums. That is where we learned a lot of what could be causing it. Maybe you need to go do some research man.

One post out of many... http://myg37.com/forums/engine-drive...-6200-rpm.html

I don't think oil temp going over 220 fahrenheit on any car will destory an engine. Mobil 1 states that their oil can still protect even the oil temp hits 400 fahrenheit.

But my question is: Is normal driving under 5K RPM and oil temp gets to 220 fahrenheit consider normal? Are there any other cars that does this? (other than G37).
