is 10W-30 motor oil thin enough for medium- mild winter temps?

live in Tennessee where the temps get sometimes as much as 10 degrees below freezing at night in the winter. and some winters it gets into the teens for a few days. but most temps in the winter are in the middle - upper 40s for highs and 20s or low 30s for for lows.

    YES! That is what it is made for. Also how many miles your engine has on it can effect oil life.

    Use only what the manufacturer suggests

    The weight of your motor oil is dependent on hat year and make vehicle you have. The oil weight is probably on the oil filler cap. Call the dealer if you don't have an owners manual to find out if different oil weights are recommended in the colder weather.

    Yes, IF that is what your vehicles manual requires in the first place.

    Stick with what is recommended by the manufacturer. This will be shown in the owner's manual and may even be written on the oil filler cap.

    The engineers that designed your vehicle know far more about your vehicle than you and I combined will ever know. I wouldn't second guessing their recommendations...

    Go with what is recommended by the manufacturer of your vehicle. Mine requires 5w-30 which provides better cold start lubrication. Aside from over-revving or critically low oil, the greatest engine wear occurs during cold starting after the vehicle has sat overnight.

    Depend wholly on your mfgr's recc. for the Y/M/M. The right oi for a Model "T" could be disastrous for a 2018 Lexus that requires synth.

    15W-50 motorcycle oil may be too thick for any liquid cooled motorcycle.

    Many newer cars specify 0W-40 synth for all climates except MT and AK.

    BTW; 10 below freezing is 22 degrees Fahrenheit. Don't confuse it with Celsius , where this would be -10 C.

    This question is best answered by reference to your owner's manual. If you do not have it, determine your exact engine and look it up on the Internet. Use the engine maker's specification for engine oil. Some engines use 10W 30, some 5W 30, some 5W 20, etc. Do as the engine maker suggests for best results.
