Hey,
Taking a road trip tommorow in te truck I bought a few months back. 1990 F150 5.8L V8
The guy was using Amsoil synthetic 10W and I just got gas and checked
the level......LOW You can't buy Amsoil at the store. Can I add Mobil 1 instead
until I can order Amosoil on the internet. Someone once told me if you change some oils or mix them the oil can turn to peanut butter. Any advice would be great!
Yeah many of the guys on this site don't like amsoil. Apparently the company is involved in some political issues that don't agree well with some of the members, I don't really know much about it. All I know is that I used it for my ATF change and it was too much of hassle to FIND it let alone PAY for it, stuff is expensive! I would switch it over to something easier to find like Mobil 1 or Valvoline. Just make sure to keep it synthetic because these high-mileage engines get used to what you've been giving them and don't react well to change. Good luck with the truck man! Sounds like the guy took pretty good care of it if he was spending the money on amsoil!
