3. Your fuels are green or blue from the addition of TCW3.
4. Your oils are dyed to make them easier to see on the dipstick.
5. You approach the additives shelf and audibly check off what works, and what's baloney.
6. That battery is only going in your car if you know who made it for the brand.
7. You chuckle and suggest MobilOne for a person suffering from iron deficiency.
8. You demand to see the MSDS breakdown for intimate lubricants.
9. Your significant other suspects you're cheating on them. You take 20 minutes to get a quart of milk because you refuse to short-trip.
10. Drain plugs where they didn't exist before.
