OOOPS!!Wrong oil!!!
I was doing the routine oil change on 97' Coupe 6spd, everything was going normal as always during an oil change. The only problem was when I was cleaning up and throwing away the oil bottles I noticed the viscocity of the oil I got was 10w-30....I had already finished the oil change and started the car...My question is, will this affect the engine? It seems to be a little slugish. And should I perform an engine flush before I change the oil?

I use 10W-30.
I believe it's better suited to the Houston weather.
According to GM it is fine down to 0 degrees F.
If it gets colder than that during the summer where you are, you should get a Sleigh.

Bottom line: If you have installed 10W-30 by mistake, it probably doesn't buy you much in the long run to drain it now, but at the next oil change be sure to replace it with at least a 5W-30 synthetic oil. Other good options are the Castrol (European) 0W-30 and Mobile 1's 0W-40. In the long run, these are better choices than a 10W-30.
