Hi everyone, I run the LYDC racing channel. On occasion I come across a vintage or new hot wheels or matchbox car straight out of the packaging that just cannot finish a race and seems oddly slow. There's a whole thread about oil already however I can't say I really noticed a common thumbs up on what works best. I'm not looking to gain an advantage within a race where I'm sending in a car but rather just trying to revive a car so that it can atleast finish a race that most other cars do easily. I've been using Marksman 3-in-1 oil and the results are noticeable however I don't want to end up causing long-term damage or gum-up after some time. This particular oil claims to lubricate, penetrate rust and clean however I've heard some can attract dust and ultimately gum-up moving parts. That all said, any input is greatly appreciated.
