Default Re: oil change question

I think that I am more concerned with the issue that the owners manual clearly states "For the LT5 engine use only 10w-30 weight oil" an it is also printed on the oil filler cap and I specifically told the shop to use it. But, alas, they used 5w-30 instead and didn't tell me. I didn't want to be neurotic about it, as the experts at Vette Doctors said it would be OK, but I had to be forced to do the research after the fact to put my mind at ease after the deed was done. Reading that specific sentence in the manual made me concerned, I felt for good reason as I am not a mechanic.
