Thanks for your prompt reply! I put in the series 2000 0w-30 Amsoil....good for the Chicago cold! I appreciate all the good info collected on this site....it helped me decide to go Lexus! thx Bill

Maybe not....check your battery terminals for corrosion and clean if necessary. good luck

Just picked up my 2001 GS430. With 44k miles on the clock..and not knowing if the oil inside is synthetic (IS there a way to tell? Smell?)....can I switch over to synthetic at any time? Worries about it being too late if running Dino oil too long. thoughts?
