Oil Change

I have a 2000 GMC Savanna van with 95555 miles. I went today to get the oil changed and when I looked at the receipt later I noticed they had put 5w20 in it as opposed to the 5w30 or 10w30 it specifies. When I called them back they said that was what they were using now. Will this cause any engine problems or should I get the oil changed, making sure they use the specified oil?

Welcome to AF, that is what they use? that is bs, the mfg calls for 5/30, make them change it!

I agree. Make them change it. Sounds like some one screwed up and didn't want to admit it.
