The goobers at my oil change station put 5W-30 in, and apparently I am supposed to be using 10W-30 or 5W-40 if it is very cold? Is 5W-30 going to present any sort of problem, should I go yell at them and make them change it again?

 

It should be fine, some people are running 0w-30 with good results, as long as it's a good oil I don't see an issue with it. I always wondered why Honda didn't spec a 5w30 as an alternative, there must be a reason for it, but I think you should be fine. In a conventional oil the 10w30 will have less viscosity index improvers which is better, but I don't think it means a whole lot over short oil change intervals.

 

Should be fine.

 

You'll be fine.

 

IMO, 5W-30 is better than 10W-30. The difference is that the 5W-30's viscosity at cold temps is not as high as 10W-30. The viscosity range when hot is the same for both grades.

I use 0W-30.

One answer: NONE!
One answer: NO!

What you should check though is the oil filter.
Did they also change that?
Did they use the S2000 specific OEM Honda 15400-PCX-004 filter?
Was it done at a Honda dealer?
If the answers are yes-no-yes you should go back and yell at them.
Honda dealers have to know better.
If it was done at an independant dealer/mechanic.. go to an official Honda dealer and buy/order 2x 15400-PCX-004 filters.
Change out the wrong filter and take one with you the next time you go in for an oil change.
