I have ~420k miles on my 98, approx 320k on the engine alone. I use 6.5qts of SuperTech (Wal-Mart oil) 5W-20 with a Motorcraft FL400S filter and nothing else. I burn about a qt every 5k miles.

 

Ok..after poor 5w20 my engine develop a tap/click noise I gained MPG but I gained this noise

 

Yes, never use any oil besides 5w-20 in these things. Got a nasty rattle when put otherwise, and that oil was black as night only after 3500 miles.

I've got 179,000 on mine, and shall never again use anything else but 5w-20.

 

All right fellows,now the oil level is killing me because this is my first F150 and I used the method of fill until the top dot and I learned today that this Trucks are different I have 7 qt in ny engine,is that too much?? And how to read this dipstick?? Thanks again

 

Too much, the 4.2 takes 6 quarts with filter change, it should bring the oil up to right around the middle of the hashmarks between the ADD and FULL line.

 

Thanks brother I'll drain out tomorrow morning

 

I see you post that, and a lot of people quote the 5.4L as taking 6qts as well, but my truck likes 6.5qts. I remember you starting a thread years ago on the FPN for the oil dipstick as some are different, but 6.0 puts me at the tip, 6.5 right in the middle.

 

Same thing here!!

 

The factory specifies 6 quarts - any more is technically overfilling it regardless of what the dipstick says.

 

Give it ALL of the oils!

 

Just curious...what can happen if I run with the dipstick on full mark?? Lets say 7 qt

From what I heard, car engines will froth the oil and the air/oil mix will lead to inadequate oil coverage.

As for my airplane's 320ci engine, she will blow out anything over 8qts. Picky things, those engines.
