I have a 97 blazer. I decided to buy Royal Purple for my next oil change because I havent heard anything but good about it, but I've heard that changing oil brands is a bad thing? I wasn't sure about that, but I figured I'd ask you guys on here. And if any of you have used Royal Purple, please let me know how it worked out for you!

 

Changing brands is not a problem for the engine. Do it with peace of mind.

 

Whew! Thanks!
