Elio Addict
I bought a Chrysler minivan new in 2001 3.8 pushrod engine. After 3000 mile breakin I switched to Amsoil synthetic. I would replace the oil filter at 12500 miles, change the oil and filter at 25000. When I sold it with 161000 miles it was only using 2 quarts between oil changes. Also used oil analysis per Amsoil recommendation. No doubt about it modern synthetic oils are the trick.
