Thats no problem mate. Personally, I feel that 5-30 crap is to thin, 5-40 is better for a turbo engine. I use 10-60 all year round, but I drive it hard.

and that you didn't read the thousands of threads saying that Rotella T6 is one of the best oils you can put in these motors, turbo or not.

superserial serious though you will be fine. there is no noticeable loss of power and it will protect your engine better.
