I know in my Honda Del Sol I used Full Synthetic oil, I have 25 more quarts of Synthetic left. Is it reccomended to use Synthetic in trucks? I know I will only ask this question once.

 

i have been using either mobil 1 or amsoil in my truck since it was new... abd before that i used the same stuff in my old ranger and it had 350,000 on it when i sold it

 

yea...oil is oil. A synthetic swap would be great. I don't have much extra time. I enjoy changing my oil every 7k. Remember, once you go synthetic, you don't go back. I run Royal Purple, but I think my next change will be Amsoil. And I only run a K&N oil filter.
