to cool oil or not.

htr · Apr 17, 2014

Can anyone comment of the benefits [or not] of fitting a engine oil cooler.

It would be fed from an adaptor fitted to the oil filter mounting.

This depend on few things:
-Engine type
-type of oil
-Type of using
-World region (hot or not)
-type of engine modifications (Synergy, Ronbox, Remap)
-Readouts of oil temperatures.

My L-series like to go up to 120* - 125*C in hot days after highway speeds. 105 -110* on normal. So i use 10W60 synthetic oil because standard 10W40 was not enough. This is a little bit to hot so cooler is needed.
Reason of this is my sump guard without grille, changed boost value and fuelling mods.
Oil temp is also important for components cooling, and for turbocharger.

Hotter oil = lower pressure. So if it will be to hot you can have problems with lubrication system. Lack of lube = pain for Engine/Turbo.

But remember - if you cool oil to much that is also not good. Your oil cooler should help to keep your oil temperature in proper values below 120 and above 90 deg. So thermostat is needed, without it you can affect engine warm up in winter.

There are some benefits to fitting an oil cooler. Oil to water cooler is the way to go. This is the layout used my the V6 Freelander. The benefits over the oil to air type are, faster oil warm up times so improving fuel economy. Also there is no need for an oil stat to prevent over cooling. Oil works well at a temperature of 80 to 100° C

Got this as standard in L-series. Not working well in summer. It also have a stat in oil pump so not helping to warm up. Small (7-9 row) Oil to air have more benefits IMO (of course it need to have thermostat to prevent over cooling in winter times)

It depends on oil type and it's specs. Some oils for "power" engines like to be over 100 (110-115). But it standard car with standard oil it should be about 10*C higher than coolant.

My Freebie has these coolers as standard.

1. Oil cooler
2. Jacto auto box cooler
3. Ird cooler
4. Engine cooler

And in emergencies I can use the cabin blower to expel heat

all auto boxes have the oil cooler I would add it to any car it would certainly keep everything a bit cooler

not a lot if not fitted as standard unless you leave it ticking over for very long periods

The adaptor plate is made in US and has a pressure bypass feature. This will shut off flow through the cooler should it be holed or a hose break [ie a sudden catastrophic drop in oil pressure]... and save your engine.

This combined with a thermostat arrangement could give the ideal set up.

I'm in an area where we get hard frosts in winter -10ºC and sometimes snow. Summer can get up the late 20s and early thirties. It would be in summer I'd be prowling around those back roads and trails up in the hills around where I live.

The cooler is an alloy one, 10 rows - 137mmx295mmx50mm. I'll think I'll go ahead with that.

Engine oil is always an interesting topic. 10W40 or 15w40? modern engine oil or 'oil for older engines'? FL is a '98 1.8 with 185000km. Do I use the 15W40 as if has a highish 'milage'? Castrol Magnatec 10W40 is what I use in my '03 R25 1.6 and all seems well and that is now past 200000km

Thank you every one, Your 'corporate' advice. This is helping me to build up a good picture of what's worth doing and what to avoid.

Imho it's completely unnecessary to have a large oil to air cooler for a standard or even mildly tuned Freelander 1.8.
Sure if it's turbo charged with an oil cooled turbo then yes, otherwise an oil to water cooler is much better. That's why manufacturers fit them.
I have an MG F VVC (K series) on the rollers it's pumping out 165Bhp. The oil temperature when flat out for an extended period nudges 150° C without an oil cooler. With an oil to water cooler the oil temperature never exceeds 120° C. Bear in mind that the MG F's engine is mid mounted so doesn't benefit from larger amounts of air cooling the engine, like there is with a front mounted engine. Just my opinion based on many years of experience with engine tuning.
Oh 10w40 semi or full synthetic is perfect for it.

I agree with Nodge!

to cool oil or not.
