What oil do you guys recommend for a 98 f150 5.4L V8 4x4. What is the factory? And what have you guys used that you really like.

 

Read my signature to get a manual.

I ran MC 5w30 (per the manual) and a MC filter.

 

Ok, i thought most people would say MC probly just gonna go with that. Run 5w30 year round?

 

Yep - ran it in my 97 for over 295k.

 

ok well then ill def be getting it and using the MC stuff, it happens to be cheaper then most stuff anyways

 

i preffer royal purple

 

Stick to what the manual tells you. Mine is going stong at 135k.

 

Mobil 1 5W30 High Mileage full synthetic....has a seal conditioner built in to the additive package that softens up the seals in an older engine.
The next oil change in my '97 4.6L will be 0W30 Mobil 1 High Mileage mainly since I got a five-quart container for only 17 bucks.

 

I would stick to what the owners manual or catalyst sticker says on the hood. That is what your vehicle is designed to use. They make different variations of it, like say your truck needs 5W20, you can run 5W20 Valvoline High mileage, or full synthetic.
