10w-60 your for real right??

feel like stirring concrete hey?

awww... wont let me update post, meant 10W-40

Since I've owned my car I've run CASTROL EDGE SPORT 0W-40.

i'm usin penrite sin, its expensive about 80 bucks for 5L and xr6t take seven soo its to bottles but worth it. sinthetic is the way to go. 10w40 is the correct oil. depending on what your doing with the car, oil loss for the xr6t is common, its due to the oil seals in the turbo leaking expencive to fix. take one of your turbo pipes off(the one that comes derectly off the turbo) and see if its got oil in it. my bet it has, ive had the same truble . good luck

On a side note its normal to have a small smear of oil in there. If its in a large quantity then you have a problem.

if you have oil in your piping, that means time for a turbo rebuild
