Thinner weight oil flows more easily that thicker oil. Most new cars today use SAE 0w-20 or SAE 5w-20 weight oil. This weight will protect you in all temperatures. If however you drive an older car that uses SAE 10w-30 or SAE 10w-40 weight oil then you might want to use a slightly lower weight oil in extreme cold.

Because - with colder winter temperatures, a thinner oil will flow more easily.

What weight oil does an F150 use for winter months?

in the winter months i found in any vehicle to use 5w-30 in the winter months being that it;s a thinner oil and run 10 w-40 in the summer being that it's thicker, cuz the thicker the oil is the longer it takes to warm up and start flowing than thinner oil does during the winter months, i made the mistake by putting the thicker oil in my truck during the winter when it really gets cold and it didnt want to start at all, i had to use a forced heater to unthaw it..

What type engine oil is used for suzuki forenza 2005?

I use 5w-30 in mine. valvaline. depending on what time of the year it is though (winter or summer) you'll want to use a thicker or thinner oil. sometimes in the summer if the oil is too thin, it triggers the engine oil light to come on. if u use too thick of an oil in the winter, you'll have trouble starting it. if been dealing with this for a couple years now. i bought mine in 07. hope this helps.


Do you use thicker oil in the winter i have a 2005 Impala 3.4?

Just use a 5w20 oil all the time. Use a thinner oil in winter if you live in a cold climate, but a 5w20 oil can be used in most all situations. In extreme cold, a thinner oil will travel up to the valve train way sooner, thus protecting your engine.

10W40 is a thinner oil, and would allow the engine to run more freely, and although both are suitable for winter usage, a thinner oil will usually help the engine start more easily in cold weather.
