fuel and oil

06 access cab manual 4.0
what fuel type and oil is best for this vehicle? thinking about going synthetic. filled up tank once so far. used hi octane. should i continue using premium or would regular do the same job?

on gas it dose not madder. i use 87 on my 4.0 trd OR 4x4 auto. SOME say they get better MPG with high oct and SOME say they get better MPG with 87. and oil i don’t think it madders ether! i’m do for oil change at like 29,8__ some or 29’9__ something so i MAY go over a few 100 and just wait till i get the full 30K service done.

 

i get slightly better mpg and performance with 93 (shell) Truck seems to be quieter to? not as loud of a tick. May just be in my head IDK. I use Amsoil, but a gallon of good ole mobile 1 synthetic from wally world is a good choice too. Just make sure NOT to use those fram filters from walmart. Go to Advance or somewhere and get a good filter. Like mobile 1 or K&N. They cost more but are better IMO.

 

Use whatever grade your owner's manual says for fuel and oil. I use amsoil, but any full synthetic is better than conventional.
