Ok guys, quick question.....is it ok if im running 5w-30 grade oil in my 5s-fe?? After i already changed my oil today to 5w-30 i realized that the oil cap and owners manual both said to use 10w-30....so my question is, is it perfectly safe to run the new 5w-30 in my engine in this summer heat, or should i change it back to 10w-30?? The owners manual sounds like the 5w-30 is meant for colder operating temps, and i dont wanna screw my engine up by runnng a thinner oil.....but at the same time i dont wanna drain the oil back out if its fine to use it. SOMEONE HELP ME OUT!!

5W30 is fine. I use it in the winter so the engine starts easier. You may consume a little more oil with the 5W30 because it is less viscous. Many people recommend switching to a heavier oil (ie 15w40) when your engine gets older so you don't burn as much oil, but this only kills the engine faster, so never do that.
