Not sure I understand about the additive. I'm a stickler for Shell (but 87 octane) and/or Chevron. Plus, an old mechanic told me Marathon had a good additive package although that was a long, long time ago.
Would I not need to worry about an additive using Shell? But if I did need an additive what should I use?
Not too familiar with nagivating a forum so if you could email me at ksnyder211@gmail.com I'd appreciate it.
Thank you.
