Personally, I trust Mobil 1 full syn. I run 5w30, with almost 70k, and I wouldnt use anything else.

Mobil 1 all the way. They have been doing Synthetic the longest..that I know of.. I have never had a problem running it and changing the oil every 4-5k.

10w30 quaker state ,and change it at least at 5000kms...this all I ever run.

its easy, if you are planing on keeping your truck for years or run it hard then you want the best protection out there. go with synthetic

I Use Q Torque Power fully synthetic 5W20. Guess whatever floats your boat.

hmm, well, truth be told - water floats my boat. Don't think that would work too well in this application :-)~

Sorry, just being a smart *****, which is much better than being a dumb one, I suppose. Ar Ar Ar - sometimes I crack even myself up! Felt the need to introduce a little (ok, very little) humor here.

Hey, it's 2:40 in the morning and I just read that and I got quite a little laugh at that...huh, I guess it's time for me to hit the sack then.

For your truck... any 5w-20 full synthetic

I'm pretty sure Ford requires a synthetic or semi synth in the newer trucks... I don't remember exacly but I'll find out if I ever get 3000 miles on my truck so I can do an oil change

AMSOIL is not a bad product if you can find a distributor in your area. Bikers have sworn by the stuff for years.

As for me I swear by Mobil 1 in all my bikes Kawi GPZ550, ZRX 1200R, HD Electraglide), my daily driver (2001 Toyota 76K on the clock no problems), and my Porsche Boxster S (15,000 miles between changes according to the manual) The only thing I run dino oil in is my Explorer.
