Is Shell Rotella t 5w40 safe for gas turbo engines. I read somewhere that it could hurt catalitic converters.
I want to start using a 5w 40 and can't find local any other brand that has it in stock. I also read this is a great oil.
I know I have asked before about it, but a lot of people are recommending a 5w40 or 10w40 for this 2.3 turbo direct injected engine...Some are saying only 5w30 works best.
