Which motor oil would be better?
If you live in NY you especially need 5W-30. Full synthetic Mobil1 is even better for the following reasons: Mobil1 5W-30 pours at -47 degrees below 0 Farenheit. Any brand non-synthetic 5W-30 pours @ 30 – 35 below 0. Plainly stated the thinner free flowing full synthetic allows the oil pump to force a greater volume of oil to critical frictional surfaces faster than ordinary mineral oil. It’s a fact 80% of all engine wear occurs during cold starts. The faster oil is pumped up-stairs inside the oil galleries less wear will happen. It also contains a better detergent package as well as extreme pressure properties. Synthetic oil is naturally more slippery and you may realize some fuel economy. Lighter viscosity oil always cools frictional surfaces more efficiently. It *adsorbs heat from the moving parts as well as the cylinder head and block much faster than thicker oil with more viscosity. Thinner oil also cools back off faster than old molassis thick oil.
