hey everyone. comin up to my next oil change and my trucks had 10w30 (been using high mileage lately) in it, even the previous owner ran that. that being said i want to switch to a 5w30 high mileage oil being thats what i read alot of members are running. its been doing fine al this time on 10w30 so just curious to know. Thanks!

o yeah. 2000 5.4 with 106,000 miles

 

What does it say on the oil cap? Or in the owners manual?

I would change over to 5W-30, for those colder mornings I would have rather have the better flowing oil in the cold and oh yeah.....

Ford recommends 5W-30 in these motors.....

 

i run 5w-20 high milage with no problems

2000 5.4 96,000

 

yeah ive been meaning to switch. and i was thinking the same thing about the colder morning starts. im lookin to try the valvoline max life 5w30 high mileage

 

There is no need to use high mileage oil, and the recommended oil for your engine is Motorcraft 5W20 semi-synthetic, along with a Motorcraft filter - both available at Walmart.

 

5w20... ftw

 

I absolutely agree. Some will tell you to switch to a "high grade" synthetic. Some will even try to sell you on the brand that they sell through their multi level marketing. But if you are diligent with changing your oil regularly, there really is no need for anything besides Motorcraft.
