    Pro's / Con's of Oil Cooler

    Now im not meaning the OE oil cooler here, but an additional oil cooler, such as http://cgi.ebay.co.uk/mocol-oil-cool...QQcmdZViewItem

    Simply an example, and I am not really planning on installing one anytime soon, just always wondered what the pro's and con's would be, obviously cooler oil, but is it really worth it in addition to the OE Oil cooler?

    Unless for some reason you are running high oil temps then no need really to get one, the stock one does a good enough job. Its only around the 120'C mark that you should consider cooling. Mine, when up and running sits at the mid 90's level all day long ocassionally going up to 100'C if im giving it some beans. If you were getting a track day car then yes and oil cooler would be a nesseciaty (sp) as you see far greater temps. Thing to remember also is that if you increase the capacity of you oil level ie 5 ltrs to 6 ltrs by the extra piping and size of rad then it will take longer for your oil to heat up, which isn't ideal on a road car. Same applys if its a very effeicent cooler in the way of direct cold air.

    You can get a thermostat with the mocal ones (about £25 I think) that opens when the oil reaches 80 degrees c. I was under the impression that an oil temp of over 100 degrees was bad news, let alone 120?

    I'd assume the standard oil cooler is good enough for a standard engine but I have CS3 so with any performance increase you get increased heat.

    With regard to track days, do you think 2 days of action on the Nurburgring in the middle of summer would warrant an extra oil cooler? I'm thinking it probably would and I'm going there in June.

    Is your car standard or modified? Was this on a cold day?

    Thing to remember with that grant is that the oil that the oil already in the radiator will be cold, so won't be ideal. Most modern semi synethics can handly 135'C as well mind.

    oil to water cooler is far more efficient than an oil to air cooler, just get a bigger rad, as has been said, or clear some space around the engine, move the battery to the boot, use a boxed cone filter instead of an airbox, use a bumper with a bigger grille area.

    So is the standard oil cooler still effective enough with modified cars being put through their paces on the track?
