winter oil?
I was wondering if I could change from 20w50 to 10w40 for winter? Would it help with 10 degree startups. I always run 20w50 but was hoping I could run 10w40 for the winter. Would it hurt the 85 12a Thanks, Vic

After about 1,000 miles the viscosity of 20W-50 breaks down a bit and becomes thinner so it wouldn't hurt to use it in the winter since you're not really horsing the car as much. Just let it warm up before you go and keep the rpms under 3,000 until it's fully warmed up.

10W-50 in the winter...are you crazy!!!!
Oil selection depends upon the prevailing seasonal temperature in your locale: moderate climate use 10W-20 or 10W-40, hot climate use 20W-40 or 20W-50, and cold climate use 5W-30.
In New Jersey, I would use 20W-40 or 20W-50 during the winter and 10W-30 or 10W-40 during the spring/summer. The key to changing is the temperature: above 50'F use 20W-40 or 20W-50 and below 50'F use 10W-30 or 10W-40.
Moreover, the widest viscosity range is best therefore I would recommend 20W-50 and 10W-40.

-25 degrees C to -30 degrees C (-13 degrees F - 86 degrees F) - SAE 10W-30
Above -25 degrees C (-13 degrees F) - SAE 10W-40 or 10W-50
Below -20 degrees C (-4 degrees F) - SAE 5W-20
Below 0 degrees C (32 degrees F) - SAE 5W-30
