If you buy car new and start using synthetic from 0 miles....ur good as long as u stay synthetic
If you buy car new and start using regular from 0 miles....ur good as long as you stay regular

If you run regular for, idk, lets say 50k miles then decide to switch to synthetic, that's when you will have problems.
