afennell Posted August 10, 2004 Share Posted August 10, 2004 after having a little play with a new m3 over the weekend the warning buzzer on the deffi gauge came on with an oil temp of 120. Is this normal after a very hard top speed run on a tt thanks Quote Link to comment Share on other sites More sharing options...
Digsy Posted August 10, 2004 Share Posted August 10, 2004 Doesn't sound excessive to me. If it was getting towarsd 130 I'd start to be concerned. North of 140 is to be avoided IMHO. Quote Link to comment Share on other sites More sharing options...
afennell Posted August 10, 2004 Author Share Posted August 10, 2004 nice one, will have to find how to adjust the warning buzzer then. suprised how fast the new m3 is! Quote Link to comment Share on other sites More sharing options...
SkyJawa Posted August 10, 2004 Share Posted August 10, 2004 Originally posted by afennell suprised how fast the new m3 is! Er, I never failed to blow them into the weeds in my old supra. That had Denso plugs, fcd, full decat, super drager and restrictor ring, so not even a massive spec............ Quote Link to comment Share on other sites More sharing options...
DaveM Posted August 10, 2004 Share Posted August 10, 2004 I used to worry about this as I have an HKS Oil Tempature gauge fitted that has a red warning light rather than a warning buzzer. The warning light comes on if the tempature goes above 100 (which it does everytime I take it out on the motorway). On the hottest day of last year (I believe it was the hottest day on record in this country ever) I remember mixing it with an X5 and the oil tempature got up around the 125-130 mark but in normal driving and in normal british weather I have never seen it go above 120. If only I could work out how to adjust the warning setting on the oil tempature gauge. Quote Link to comment Share on other sites More sharing options...
Nick Posted August 10, 2004 Share Posted August 10, 2004 Originally posted by DaveM If only I could work out how to adjust the warning setting on the oil tempature gauge. I've got some instructions at home that detail how to change the warning levels on the HKS boost gauge. I expect the oil temp will be the same or very similar, I know the EGT is. If you have access to a fax PM me your number and I'll send them over on Monday. Quote Link to comment Share on other sites More sharing options...
afennell Posted August 11, 2004 Author Share Posted August 11, 2004 i was faster then the m3 but not by much. arn't the new ones around 400 bhp? (was running standard boost at the time) Quote Link to comment Share on other sites More sharing options...
Paul R Posted August 11, 2004 Share Posted August 11, 2004 Hi, I have a GReady guage in my car. The temp never goes above 100. Even on the hottest days It's amazing what a GReady oil cooler does for the temp of the car Paul. Quote Link to comment Share on other sites More sharing options...
Zed Posted August 11, 2004 Share Posted August 11, 2004 i was faster then the m3 but not by much. arn't the new ones around 400 bhp? (was running standard boost at the time) No, the m3 is 340 bhp, even the lightweight csl version is 360 bhp. The current m5 is 400 bhp. They are quick cars, but I've driven a few and you feel quite isolated from everything so it dosent actually feel like your going that fast, it also feels like your really thrashing the engine once you do start using the performance.

Nick Posted August 11, 2004 Share Posted August 11, 2004 They're quick cars and a decatted Supra won't blow it away if the driver is half awake. My mates one will keep up with me until around 140mph and it's only then I start to pull away. Quote Link to comment Share on other sites More sharing options...

Digsy Posted August 11, 2004 Share Posted August 11, 2004 Originally posted by Scooter can oil temp be too cool? is there an ideal temp range....... The main risk from cold oil is pressure spikes on startup, altough I suspect there is an optimum temperature range. I'm no tribologist, but it seems logical. In practise you pick the oil accoring to the blahWblah rating anyway, which is effectively its normal temperature range. Most of the problems encountered during engine development are to do with the oil getting too hot, and the pressure (usually in the head) dropping. Extra-hot oil may be an issue for VVT-i cars as the cam phaser is operated hydraulically. However I was looking at the gubbins on Sunday and it seems to have it's own external oil feed (via a honking great big banjo bolt). I didn't check where the feed came from, but it may be somewhere near the pump where the oil is stil nice and cool. Quote Link to comment Share on other sites More sharing options...
SimonB Posted August 11, 2004 Share Posted August 11, 2004 The other problem with oil that is too cool is that moisture doesn't boil off as vapour. Decent oil cooler setups have a thermostatic valve that only routes oil through the cooler when it gets above a certain temp, so it doesn't takes ages to warm up on startup.

Zed Posted August 12, 2004 Share Posted August 12, 2004 I was also wondering about oil being overcooled. I've just fitted a 16 row mocal oil cooler which sits behind the bumper vent on the passenger side. I was thinking, is it possible for the oil to be overcooled during the winter months when there are temps below freezing or is this unlikely to happen as the hot oil is circulating ?

SimonB Posted August 12, 2004 Share Posted August 12, 2004 It will probably just mean that it takes ages to warm up in the winter. If you're worried about it you can get an oil thermostat (oilstat) that will only route oil through the cooler when needed and plumb that in. Mocal do them, they're not expensive.

Zed Posted August 12, 2004 Share Posted August 12, 2004 Cheers Simon, might look into that, although it was a right pain fitting the adaptor in the original oil filter location so it's not a job i'd look forward to. Quote Link to comment Share on other sites More sharing options...
SimonB Posted August 12, 2004 Share Posted August 12, 2004 You wouldn't necessarily have to take the adaptor off, you could put the oilstat by the cooler. You can get stand-alone ones that have 4 connectors, in and out connectors and a oil cooler in and out connector. Quote Link to comment Share on other sites More sharing options...
Zed Posted August 12, 2004 Share Posted August 12, 2004 Cheers for that Simon, now my wallet's got another thing to worry about. :) Quote Link to comment Share on other sites More sharing options...
