Does temperature affect the viscosity of oil? If so how?

Does temperature affect the viscosity of oil?


Why is it thinner when it's hot.. and vice versa.


Explain what happens to the particles etc.


THANKS!!Does temperature affect the viscosity of oil? If so how?

these 2 should do it for you. lots more where they came fromDoes temperature affect the viscosity of oil? If so how?
Yes temperature effects the viscosity.of oil


Oil is thinner when heated because the molecules are moving faster and taking up more space.


When cold the oil contracts and the molecules are moving slower

What is the viscosity of mobil shc 634 synthetic oil?

The viscosity is 161. ';Mobil SHC 634 (ISO 460) synthetic gear oil is the ultimate worm drive gearbox lubricant. SHC 634 will greatly extend worm gearbox life. The gearbox will run cooler, easier, with reduced power loss. Sold in 5 gallon pails.';

What is the viscosity of corn syrup and vegetable oil?

Here are some links that should tell you.

    if the manufacturer says on the car manual use 5w30 that's the oil you have to use no matter the age of the car or the millage





    is a myth that you have to use a higher grade oil when engines get old or get high millage





    so read the car manual and use the oil it says





    if you use gear oil on the engine you will kill it instantly because gear oil are used to lubricate not eliminate friction like engine oil do
    W10-30 should do it or check your owners manual!!
    look in owners manual

    I have a 1994 caprice, 5.7l tpi, 120,000 miles, runs good, What would be the best type and viscosity of oil ?

    To start using in this car, for the longest rest of its life?, Oil, Filter,?, I live in OregonI have a 1994 caprice, 5.7l tpi, 120,000 miles, runs good, What would be the best type and viscosity of oil ?
    Oh my gosh, you live in outreaches of Oregon and the guy above advised 40W? *Not in your lifetime. The factory recommended oil to use is 5W-30 year round. You can't beat AC-Delco, NAPA (made by Wix) or Wix by name oil filters.





    I can imagine you have wide temperature swings. 5W-30 allows the oil pump to force the greatest *volume of oil to frictional surfaces quickly. Hot or cold start-up is where 80% of engine wear occurs. It's to your motors advantage to receive instant lubrication instead of an oil pan filled with ';molasses'; - 40W.





    Light oil, (5W-30) also cools internal engine parts faster and more efficiently than heavy thick oil.I have a 1994 caprice, 5.7l tpi, 120,000 miles, runs good, What would be the best type and viscosity of oil ?

    How does temperature of oil affect its viscosity?

    plz i have to make a report a bout this but i dono nothing i need ur help guys plz. and quickly plzHow does temperature of oil affect its viscosity?
    -When a substance (any substance, not just oil) is heated the viscosity of the substance decreases





    -When a substance is cooled the viscosity of the substance increases (it gets stickier)How does temperature of oil affect its viscosity?
    as Victor says, and with oil, (for full marks) you need to explain VI


    or


    viscosity index

    97 honda valkyrie,hot southern climate ,oil viscosity suggestions?

    97 valkyrie purchased this spring,absolutely love it.live in central texas,hot summers,any suggestions on oil types,viscositys?97 honda valkyrie,hot southern climate ,oil viscosity suggestions?
    Of all motorcycles,,the Valkyrie is probly the Mother of all ';Oil Controversies';.





    The things have been so reliable,,and rolled up so many miles,,,it's easy to come to the conclusion that it really doesn't much matter What oil is used.





    Me personally,,I do not understand the rationale of trying to save $10~15~20 per oil change,,for 2~3 ~4 oil changes Annually.





    On the OTHER Hand,,,,there's a Group of Premium Oils which range in price from about $5qt to over $25qt.





    Once it's understood what Extreme,Vast ';Overkill'; ALLLL of those oils are,,,it makes as little sense to spend Too Much as it does to try to Save $20/Year.


    ......................................鈥?br>

    Mobil 1 Synthetics have such wide temp range,,they are good at:


    a)almost TWICE the temp your engine Can even run at(450~500+ *F)


    %26amp;


    b)temps Colder than you can even humanly function at to Ride.(Below -40~50~60*F)





    You can run Same oil,,Year Round,,anywhere on Earth,and be 200% Confident that Oil is the Least of your worries,,,actually No Concern at all.





    Mobil 1 has a 20w~50 ';V-Twin'; Motorcycle -Specific oil which is exceptionally Good.


    It's Pricey,,and can be a bit sketchy to find.





    They also have a 15w-50 ';Car Oil'; which is perfectly fine for use in motorcycles.


    Overall,,,all things considered,,,it may well be THE Best Choice ,





    Starting with the fact that it's among the Cheapest of all premium oils,,


    and it's regular stock at Wal-Mart.....as well as most any place that stocks Mobil 1.





    I'm no big fan of Wal-Mart,,,,but in this case what it means is that YOUR OIL is available ';24/7/365'; practically ANYWHERE you happen to find yourself needing oil.





    Thats what my Best Suggestion would be





    Mobil 1 15w-50

    ......................................鈥?br>

    You also have ';rear end'; oil to consider.





    Belray Gearsaver Hypoid Oil,,80w~90


    Most bike shops have it97 honda valkyrie,hot southern climate ,oil viscosity suggestions?
    Its water cooled, its a Honda.... you should use a high quality oil anyway. But you ain't gonna get this bike hot.. ever. Yes its a monster, but its a beautiful monster. Its not gonna give you one bit of heat related problems. Even if you were in my neck o' the woods (Corpus).
    Check the manual, but guessing at 20W/50
