Mobil1, What is the deal???

[Z U L8R]

make me some 7.5w-30

i just don't feel peace with 2 qts of 10w-30 and 2 qts of 5w-30 = 7.5w-30 LOL

i'm using 5w-30 with lucas.....which by the way was really expensive so it better do something magical....it better lubricate my muffler bearings

I assume you're using the 'Lucas Synthetic Oil Stabilizer'? It is available in 55 gallon drums

Creating 7.5w just means you can crank it in temperatures down to -22.5°C (-8.5°F) and the oil pump should be able to pick it up down to -32.5°C (-26.5°F) Really minor changes in that first number isn't that big of a deal, only a 5° differance between 5w & 10w.
