Autumn oil temp!
Discussion
I have only owed my T350 for 5 months (NOTHING BUT PURE ENJOYMENT I MIGHT HAD!! :D ), but have noticed with winter fast approaching, maintaining useable oil temperature is becoming very hard!
I'm even starting to pray for lights to turn red, traffic jams, old women to cross the dam road - anything that will give me an excuse to stop and let the engine push the oil temperature above 70! Surely this is only going to get worse as the cold weather sets in - does this mean I have to wait until spring to enjoy the car again?
Has anyone found a way around this problem?

Very good point, one that is got me thinking as well.!
I was told that under 50 degrees, don't even think about throttle above 3k, and 70 degrees is normal op temp.
As you say, temp can quite easily be in the 40s, even when you think engine is hot.!
Def one to watch, could be a contributor to engines going pop in past, where owners have not realised.

I don't know about you lot but my car (Sagaris) seems to limit the revs when the oil temp is below 60. The shift up light comes on earlier than normal. But I agree it's hard to get sufficient temp in the car at this time of year.
the cooling has been so improved on the Sagaris to work in hot conditions it makes it a bit overkill for the rest of the year in the UK. I was getting temps in the low 50's after long motorway work some time ago. I guess on balance it's better this way. Certainly cold winter days are a no, no for high revs it would seem.

Factory advice last winter on my T350 was that in cold weather the oil temp sensor may read up to 10C lower than the actual engine oil temp (even lower when icy) because it reads from the dry sump tank, sitting in the cold airstream in front of the engine. You'll see this effect increasing at higher road speeds, for obvious reasons
Before I asked them, I experimented with simple insulation of the oil tank & water rad, but even blocking half the rad and insulating all the front of the oil tank had little effect!

Looks like there is little we can do then - just err on the cautious side over winter! Oh well at least we will save on petrol!

Yep Ive come across this...also in wet conditions and Ive found that once again common sense comes to the rescue.
Basically dont go above 2.5k rpm until 40 and then 3k rpm until 50.
Now if you hit a motorway or dual carriageway before your engine has warmed up, I find my engine struggles ever to say it has got above 50. Now I know this is essentially bollox. I also get this is wet weather travelling on the M-way, my oil temps can often be high 40's or smack around 50. Whilst I am more careful at these times, I work in the TVR factor and work on the real temps of the engine being 10 higher than the dash readings. That puts my car again in the high 50s, to 60 or so and I know that is just fine.

DJC's approach seems good. Can't insulate sensor as it is in the oil in the tank, probably giving a correct reading, just not reading the higher temp in the engine a few feet away. If there was an actual oil cooler it could simply be blanked off (or more professionally, isolated by a thermostat as suggested) but TVR obviously found the oil kept cool enough to avoid the extra cost and complexity of this; fair enough.

Hi,
Just joined and after reading this thread seems my T350C is also running pretty cool. On motorways it sits between 60-65 and only when sitting in traffic does it ever climb much above 70.
My question, is what temp are people getting just after starting from cold. I seem to regularly get temps below outside levels like 4-6degC. Once, first temp was zero before it started rising. My friend's T350C runs about 15-20degC after cold start and then runs 70-80 in normal use. I'm wondering if my temps are just calibrated low? Anyone else get levels this low after cold start?
Rgds,
Darren

Darren - would agree that your oil temps sound low. My Tuscan sits outside all year around and temp is usually 12-15 upon start up, going to 60 or thereabouts when m-way driving. Goes higher in traffic/slower driving.
Oil sensors - would not hold your breathe. I have tried to source an oil pressure sensor for 3 mths and no luck (factory is out supposedly). Same goes for water temp sensor which is more of an issue - overheating a real risk (has happened to me twice now). Good luck if you go this path!

Thanks for the advice Mustang Baz and Tail Slide. New oil temp sensor fitted by Racing Green this morning and seems to have done the trick. Before it was fitted this morning's oil temp before start was -2degC!
New sensor was 15+vat plus an hour's labour. So not too bad. Apparently the same sensor is used for water temp and they go crazy when faulty rather than give no reading. Mechanic said they're about to introduce a Bosch sensor to improve reliability. Forgot to ask who makes the current ones.
