MOBIL1 tends to run a bit thinner within given spec windows for some of its oil than many competitors.This is a reason many car manufacturers like it so much to squeeze out the last few mpg they can for EPA and CAFE reasons.
But if you use MOBIL1 in it's 15w-50 viscosity it will do well in a turbo.
In general, NEVER use anything thinner than a 40 weight oil in a turbocharged engine and alwasy remember to idle the car at least a couple min before shut down and after starting.

PS: Examples of acceptable oil viscosities in turbos as a minimum 0w-40 and up. 5w-40, 10w-40, 15w-40, 10w-50, 15w-50, 20w-50. (not all of these grades may be locally available)Inn turbos it's especially important to run synthetics.
