5w-40 vs 10w-40 oil 151129-Which is better 5w 40 or 10w 40
Re 15w40 vs 5w40 You can run the 15w40 OR the 5w40 with no issues I lived in the Victor Valley area, not far from you and at a higher elevation for 15 years and ran the 5w40 no matter what brand it was and never had an issueA higher viscosity oil, such as 10w30, will flow slower at low temperatures compared to a lower viscosity oil like 5w30 This is important because viscosity changes as temperatures change Viscosity decreases as the temperature of the oil increases A higher viscosity or thicker oil will seal better than a low viscosity oil10W40 is thicker than 10W30 at higher operating temperatures 10W40 will have a higher viscosity at operating temperatures than 10W30 Oil that is able to maintain its thickness at high operating temperatures has many benefits to show for Generally Better In Warm Weather Thin oil and heat don't go well together, to say the least 10w 40 Oil Mobil Which is better 5w 40 or 10w 40
