My son is an engineer for an OEM new vehicle manufacturer and their latest concern is customer complaints this spring/ summer due to winter fuel. Apparently the fuel distributors are required to switch to summer fuel by a certain date as the weather warms but this year they have been allowed to extend that deadline. Due to the Covid-19 and a low demand for fuel there is a hugh backlog of winter fuel in the system. As I understand it winter fuel vaporizes easier for winter starting but using it in warmer weather can cause check engine lights, hesitation, stumble and vapor lock issues.
The vehicle manufacturers can not do anything about it and the problem will disappear as soon as the summer fuel makes its way to the pumps
If we have issues this spring be patient and don’t drive yourself crazy trying to fix something that will go away
