10w40 grade for winter?

[lunap]

I have been using 10w40 oil and due for a change. What are you using for cold winters, same grade? normal or Synthetic?

Also changing coolant - what do you do with disposing liquids?

I switch to 10W30 for winter, but you could probably get away with 10W40, unless you drive in sub -10 to -20 weather. I use regular oil. Synthetic seems to find leaks in older seals.

You can take used coolant to have it recycled. NAPA takes it.

i run 10w30 or 10w40 in the winter and 20w50 in the summer. for coolant, it goes down the sink drain...the water treatment plants use ethlyn glycol (yeah, i know...i spelled that wrong) when they treat the water...just don't dump it down storm drains...it has to go down a drain that will go to a treatment plant.
