oil heating up?

[tunepipe911]

hey

next question from a T350t newby,
The manual says that oil should always be 65 degrees and above,before revs can be above 2500 rpm,
problem is that it takes at least 15 miles and more,is this normal?


thanks

Yes. The colder outside, the slower the temp rises.

revs v oil temp is a long debated subject on here, sure there will be some threads you could look at. But yes, as said, can take a while for the oil temp to reach optimum, I normally take the max revs in stages in line with the oil temp - i.e. <40 deg - upto 2k revs, <50 deg - upto 3k revs, <60deg - upto 4k revs, >70deg - go for it....

Hi,
I had similar issues with my T350C. Solved to a large extent by fitting a heating pad to the bottom of the oil tank. Connect it up about an hour before I want to go out and the oil is usually up to the mid 40's before I set off. Doesn't take very long to reach 65 after that. Obviously, if I make a sudden decision to go out, I have to put up with the traditional oil temperature warm up period, but that doesn't happen too often.
If you are interested in the heating pad, there was a thread on here where we did a group buy, I think it was about £35.

They sell them on eBay too. Wolverine oil heater. Routed mine to a connector behind the number plate.

Engine Heater Oil Pan Heater 250 Watt Wolverine W16-220 220/240 volt

This is what I bought only about £60 shipped to UK

First of all I get the revs up to 1200-1600 for at least 5 seconds right after start to help getting the oil to where its needed as fast as possible. Worst thing you can do is idling too long after start, when the engine is still cold. I do not rev above 3000 rpms until the dash shows at least 65°C.

But since the oil temp sensor is in the oil reservoir upfront and gets all the airflow, the readings do not reflect the actual oil temp inside the engine itself (unfortunately). Especially when you drive on cold days.

I noticed, that I get the pops and bangs not before the oil is at elevated temperature. So this is also an indication for me.

I do not give it the beans until fully warmed though. So 80°C and higher. One indication is, that it gets awfully warm from the motor (bulkhead) and armrest (gearbox).

And yes, depending on drive-cycle (town/motorway) it takes up to 15 minutes even on warmer days until I am convinced, that the oil is at working temperature.

As far as I understand, revving up isn't necessarily the most severe problem you can face, but high pressures inside the engine from depressing the loud panel too much from cold.

You can drive at <2K revs? The must be blip, blip, blip, blip, chug along at 50mph?

I believe the temperaure displayed on the dash is affected by the position of the sensor. In cold weather I can struggle to get the oil to show 50C on a motorway but I don't believe the oil circulating round my engine is really less than 50C.

Just take it easy to start off with in cold weather and keep the revs reasonable, you can kinda tell from the enginge feel / noise whent he oil has warmed up a bit.

please consider that also the thermostat could open to early ..

Makes no difference if oil is "cooled" by water flow at 74 or 82 degrees. The problem is to get the oil up to 60 and above.

I agree, get it up to 2,500 as 2,000 is far too low.

Here's the generally accepted norm and get a Wolverine for cold weather

Start the engine with minimum use of throttle.
Drive off as soon as possible.
Keep under 2,500 RPM until oil temp is at least 40°C.
Keep under 4,000 RPM until oil temp is at least 50°C.
Keep under 6,500 RPM until oil temp is at least 65°C.
If temp exceeds 110°C, keep revs below 5,000 RPM.
On colder days, some people report their oil temp never reaching above 60°C, so common sense should be applied in all cases.

Topic Closed!

sorry, makes a big difference if the thermostat opens to early (or stays open) as i had this symptoms and it took a long way until oil and water was "warm"

with the new 82°c thermo it's now pretty fast at the right temp-level for both at the same circumstances/conditions.

Don't let it chug along at 50mph. This is as bad or worse than hi revs (i am no expert). Higher revs will up the oil pressure & maybe pop oil seals out but chugging at low revs with cold thick oil is where the real damage can happen.
Agree with the 1000-1500 for 5 secs but takes concentratio with the hair trigger throttle.
In the cold when i get to about 40° i will pull over & idle it at about 1500 to help get temp in to it otherwise the airflow wont let you get higher for ages.

Here is even worse: Low revs, cold oil and high load. Like giving full throttle from below 2000rpms when oil is still cold.
