Yesteday I was out for a little joy ride with my friend and his bike (beleive it or not, his bike was faster then my 335i). We werent gone too long but i notice my car (well oil temp) was getting kinda warm, like 250-260 range. Is this dangerious? My car is going in for service this weekend, should i beg them for a oil cooler?

FYI; Im driving a 2007 steptronic 335i e90, weather was clear and 45 degrees (fahrenheit) and low humdity. altitude like 200-300 ft

You're gonna need it to be hotter than that to get approved for an OC. It won't go into limp mode until about 300. Mine got to 265 on a track (mid 60s for temp), with the OC. So 250 is not bad..

^^^Agreed. But never hurts to inquire.

[persian54]

I'm at 240 daily

260 during spirited

I freaked out too when it first happened lol

[EuroTrip]

Yeah, ill second the 240. I only get to 255ish when in traffic for an hour.

I'm not really responding to your question but I would say that I do believe you when you said your friend's bike was faster than your 335i. I'm assuming you are talking about a sportbike (liter bike), It'll be faster than any BMW production car ever built, let it be M3, M5 or M6.

Engine oil temps should run right at 212f in normal conditions and driving. That is to drive out moister from oil. That means in air temps up to 120f you shouldn't see much above that 212f. If your towing or driving hard and fast say up over 80mph or climbing grads with a load (passengers and luggage, heavy) A/C on in high air temps above 100f you shouldn't see any oil temps over 230f. If you own a air cooled car you may see higher temps. Now the killer, the engine in the 335i runs these temps above all any reasonable standards all the time. Normal in 335i would be pull off the road and let it cool down stuff in the past. Buy a 335i at your own risk this is unreasonable oil temps and big red flags for us gear heads....When the 335i first came onto the market and people saw the oil temps they were running we were flabbergasted. Many like me just said never going to own anything with that engine, its doomed. Your gut is right on (Too Hot), heat is bad for engines and reduces life. Good luck.

I hope you were kidding - power to weight ratio+aerodynamics of a sportbike will smoke any car on the streets. Wanna lose again to my cbr??

[200Duece]

I am really surprised that you got owned by a Schwinn

Of course im kidding, and no i dont. But my friend was freezing after our ride and i was enjoying music and heat the enture time

I did hear about a 1000whp corvette that kept up pretty well with a Street bike. Pretty impressive but then again thats no production car.

Will ill ask the Dealer if they feel like puttin a oil cooler on... if not, whatever, its still on warrenty

Been a while since you checked into operating temps for Synthetic oils I guess -

http://www.mobil.com/USA-English/Lub...bil1_5W-30.asp

Flash Point, ºC, ASTM D 92 230

So were safe as long as we keep it below 446 degrees!

+1 I read the doom and gloom oil temp posts and usually just let it go, synthetics regularly stay under 10% viscosity lose at 400F. Amsoil posts that right on their website. Total has some oils with even higher potential.

[HoustonScott]

Checked out the site, been there, oh, by the way not a mention on site about high engine temps, you will have to do better than that, we all know synthetic oils stay stable at higher temps. If you think an engine running everyday temps in the 240f's is OK because the new oils can take it, your in need of some education about engines. It is my opinion when all is said and done with HPFP failures you will find they fail because of high temps the engine is running, it's all related. The guy in the thread that says his oil temps get to 255f in bumper to bumper traffic, that's scary stuff. I like a car that cools down no matter how hot outside when at idle. Telling yourself it's normal is dumb, it's not normal for any engine, it's a flaw in the design of the engine.

In fact, the Mobil 1 AU site DOES list 350 as max temp for M1. If you require it I can find the link.. but something tells me you 'know better'.

The THERMOSTATS for oil coolers don't open until 240. The turbos mount close to the engine - they will naturally retain more heat. I have been building engines since the mid 70s.. I think I know a little about them and what they can take.

It is my opinion when all is said and done with HPFP failures you will find they fail because of high temps the engine is running,

I'm pretty sure BMW would have just about identified that as a problem if it were the case. You know what a dyno durability cycle is? It normally involves running an engine at RATED OUTPUT on a dyno for hundreds of hours. GM has 100 hours at rated torque and then 100 hours at rated HP. Im pretty sure that if the oil temp would be the death of these things it would show up on the dyno.

[HoustonScott]

If you want to argue that high oil temps and hot engines and are good and run longer and are more reliable and normal now, go ahead, I argue that heat is the enemy of an engine and oil temps in engines operating in normal day to day use on the streets of America should not be up at anything close to 240f, you can have that it yours.

As with anything there are limits - 250 is NOT danger to current design emission motors with proper oiling and lubrication.

you should search for videos of "turbo hayabusa" sometime

Depending of your definition of fast (ie. 0-60 vs say 80-140), ANY super-sport class crotch rocket from the big 4 of 600cc or higher will be faster than ANY production car, BMW or otherwise, to 60 mph. The current crop of super-sports average between 2.9s-3.1s or so to 60 - some of the lighter 600s are actually a couple of 1/10s quicker to 60 than their liter brothers, before they fall prey to the longer legs of the higher displacement bikes when they get into triple digits.

Which means my Dinan E92 feels like a bit of a dog around town after riding my R1, but so it goes

OT, but one of my all time faves:

[HoustonScott]

Did some searches for what oil temps run in a F1 engine in race conditions. Oh, by the way were talking 19000rpm stuff now. What I found was 100c is normal or just above, that's 212F.

[335e92tx]

Fuel consumption and emission are not their primary concern - not surprising.
NASCAR water temps are generally 240 and up (water temp is in almost all circumstances less than oil)

[cotmfk]

I think in 06 or a little earlier, Yamaha R1 was 9.9 seconds in the 1/4 mile STOCK! Good luck trying to get anything close to that on a stock 335.
