I bought 7 quarts of Mobil1 5-w30. Now i find out that its only for -40 to 25 degrees ferenheight. The coldest it generally gets around here in the winter is about 20f.
Do i go back and exchange it for another type? Which weight?

You sure that shouldnt mean centigrade instead of F? -40f, is Barrow, Alaska,,,,in the summer.Originally Posted by Alexlind123

-40 is the same in centigrade and farenheight.

Ah,,,no, grasshopper, it is not.

-40 farenheight is about 70 below freezing 25 farenheight is still below freezing
i think they are centigrade temps...whatever the 5w will give you good protection at statup cos it wil be quick to pump...the 30 weight is still good,maybe get a 40 w next time

According to the manual, it is 24farenheight, but maybe synthetic oil is different. Does this mean i dont have to take it back to exchange for a different type? I dont see why any store around here would even sell it if it wer eonly suitable for such incredibly low temperatures.

I put that in recently as i live in the Northeast US. The temps didn't fall as fast as i anticipated and i ended up burning off a quart. I hadn't added any oil in the previous three months since buying the car so its pretty thin stuff .

i would actually exchange it for 5W40 synthetic (Turbo Diesel Truck formulation) as that provides significantly higher anti-wear additives and a weight of M1 thats a bit more friendly to your engine when you push it hard.
it has a higher "cold" viscosity than 5W30 which should result in more stable idle as well.

... actually -40C is EXACTLY the same value in farenheight, that is the numerical balance point, every 5C difference from that point = 9F difference.
-40 + 60C (12x5) = -40 + 108F (12x9), which translates to 20C = 68F (room temp)
