I need help, and opinions about Royal purple, and other oils from the community here. I started using it for my oil changes, but I think my engine is a little louder than usual especially until it warms up. I did read that some people believe that it's watered down garbage. Do you think I'm being paranoid because I read that? There was also a part that said something about it having a lot of Zinc in it, and I don't know what that would do.
I thought about using Mobil one, but know I hear some don't consider that a real oil anymore.
Since I've been playing with motors just about all my life I've learned oil is like our own blood very important. So please feel free to give me any, and all of your opinions.
Also the RP was around 80 bucks for the oil, and filter is that normal?
BTW When I got my truck I thought the exhaust was a little loud so I had it checked for leaks, and there didn't seem to be any. Is the 3.7 a little loud around the front pipes, or do they have a hidden leaky spot.
