I got to thinking if it were summer would it really matter if I ran Mobil 1 10w30 in a pinch if the 5w30 was not available? Summer only I'm talking.
Will not affect it negatively at all, sir.
And your state feels like Canada in winter and Miami in the summer. It is amazing.
Seriously though.. it is 100% fine. And you could even be on the South Shore and use that Mobil 1 10w30 in winter, if you HAD to.. all the times I came out at 5AM to bring the car for my friend, and it was a crisp 4 degrees Fahrenheit on the bank sign. Or 7 degrees. I ran a 0W-20 in that car, but. That oil (Mobil 1 10w30) and that vehicle.. even then. EVEN THEN you could use it in the South Shore in the winter. . If you HAD to. In the summer, the engine will never know the difference.
And... not sure why it has not been said, but.. perhaps try Mobil 1 Advanced Fuel Economy 0w30 (still made?) If sticking with Mobil 1 for that truck... we love 0W here... its the best..
