    Normally I run mobile 1 5w-30. Now that it's summer, should I go with 10w-40?

    Short answer: no.

    Long answer: Modern vehicles have efficient cooling systems and if yours is in good shape, in TX you won't need to change motor oil viscosity with the seasons. Some people who live in areas with extreme cold winters will go with thinner stuff in the winter but most climates don't need this. Stick with 5w30 and you'll be fine.

    No.....

    I run 0w~30 year round even in my heat! I have read that 0 (or 5) even helps when it's 75° out side at start up.


    And then I do not have to worry about changing oil when it might get cold :D
