I have a 1997 Ford Explorer Limited with 4.0L SOHC with close to 89,000 miles. I am wondering what visocity of oil should I use Mobil 1 or Amsoil 5W-30. Or which you recommend? My friend told me to ask forums like this for a feedback.
I also have 1993 Ford Explorer Limited 4.0L V-6 with 201,000 highway miles and is leaking oil at rear main seal and oil pan. I just ordered auto-rx and hope it would slow down the leak if not stop it. I was told not to use Amsoil for this because of the leaking. Any suggestion would be appreciated thanks!
