A good oil choice for new cars would be a multiviscosity 5W-30 oil which is very light and convenient for every day regular driving. If your car engine is not so new, then a 10W-30 would be a good oil choice. Also, if you usually drive your car in a hot weather and at a high speed, then a 10W-30 or a 10W-40 would be a good oil to use.
