Answertp protect your warranty it's aways best to follow the manufactor specifications however after the warranty repairs are up to you to do and out of your pocket.
here's textbook oil talk for you
most engine oils are multiviscosity oils. these oils carry a combined classification such as 10W-30. basically this rating says the oil has the viscosity of both a 10-and a 30- weight oil. the W after the 10 notes that the oil's viscosity was tested at 0degreesf (-18C). the 30 rating is the hot rating. this rating was the result of testing the oil's viscosity at 212degreesF (100C)
to formulate multiviscosity oil's, polymers are blended into the oil. the polymers expand when heated. with the ploymers, the oil maintains its viscosity to the point where it is equal to a 30-weight oil.
The SAE classification and the API rating are usually indicated on oil containers. selecting oils that specifically meet or exceed the manufacturer's recommendations and changing the oil on a regular basis will allow the owner to get the maximum service life from an engine.
hope that textbook knowledge helps.
as stated exceeding the recommendation is never a bad thing however watch what the warrenty says
