Scotty, I have a 2000 Acura RL with 122k mile, 3.5L engine. It’s been garaged for the past 5-6 years, not driven, it ran fine before I stored it. I just put a new battery in it and started it up and it makes a ticking noise from the engine bay. Is this something that Marvel’s Mystery Oil might fix? I’m not handy enough to fix it if it’s the lifters or tappets so otherwise I’d have to have a real mechanic look at it. Would it be safe to drive?

No. 1-1


worth a try, put some in , run it a while, then change the oil and filter and pray
