25W70 is for girlie boys. Real men use 40W70!

That comment was directly related to a poster from the UK that reckoned he had a huge drop in fuel consumption in winter.

I use a/c in the summer when it's hot but not in the winter at all (save for a few 'seal conditioning' runs). The main factor in the winter is the cold starting, with thicker oil and a cold block that needs more energy to heat it up. Once at operating temperature the fluids will be more-or-less the same viscosity. If you are genuinely seeing a 40% change then you need it looking at.

Are you kidding? Try driving 100KPH down a highway at -30C with that temperature air blowing over your rear axle. You can stop anytime and touch the axle, and its not even warm. What viscosity do you think that fluid is?

OK, ca you repeat your question?
What temperature is then motor oil if you drive 100kph at -30c (I did many times, so please tell me it is not on operating temp).

You might find it's due to the winter grade fuel as well. It's no way near as "pure" as summer grade fuel. We have a drop in mpg in England on winter fuel so it's probably much worse at your temps.


Yes i believe you did say 40% increase due to "thick" fluids in the winter.

Since a huge percentage of UK vehicles now spec on 5w30 i don't consider that to be a particularly thick fluid.

He did not write that. He was quoting member Bluestream, but forgot to include the quote tags.

The oil temperature would be vehicle specific at -30C

So wait. Your claim is that at -30, if you drive 100kph you oil will not reach operating temp?

At -30 the wind chill on his diff and sump @ 70mph will be very, very bad so I'd say he is absolutely correct. That's why manufacturers usually give oil recommendations based on ambient temps because they know this happens.

So while your statement that at operating temp they are the same is true, his oils will never get to full operating temp due to his ambient temps.
