im wondering what the best type of oil is to run in my 2003 ford f150 5.4 l

takethis2urgrv

i stick to what ford recommends.. motorcraft 5w-20 synthetic blend...i have had my 03 f150 5.4 for 4 yrs and run the motorcraft oil and it runs like a charm.

I use either Quaker State Full Synthetic,or Pennzoil Platinum Full Synthetic,or Valvoline Full Synthetic..Jack Roush use a Valvoline Full Synthetic but he adds an additive to his I do not know for sure but it is probably some Lucas oil additive to it..just some FYI,,But I will tell you I have been using the Quaker State Full synthetic 10 w 30 in mine I have 221k miles on it and it does not loose a drop or burn any off,If i use 5w20 or if I use BP's Castrol GTX synthetic or GTX High Mileage 10 w 30 it seems to loose some between oil changes and I go 5000 to 6000 miles on an oil change..I hope this helps..

Run what you want just always run the same kind and change it every 3000 miles

ok thank you all so much.i didnt know if you could run a weight that was higher then 5w-20,5w-20 seems really thin

I use what is recommended. Motorcrafter 5w20. I don't burn any oil or leak any.

I spoke with an engineer today from Pennzoil,he told me that the 5w30 or 10w30 synthetic or synthetic blend would be fine in the 5.4 Fords,especially with higher than 75k miles on it but he said once you go to the 30 weights you need to stay with them,He actually Recommended the Rotella 10 w30 synthetic Blend to use in the Ford Truck motors.He said it is very durable and will keep it clean and It has a advantage on the Heavy Trucks like with the V-10 that it will help keep the Valves and Valve train lubricated especially at cold or dry starts it will prolong the Valve train significantly he said.So just passing on the info hope it helps...
