1999 V-6 Question
We just got a '99 F-150 V-6 Saturday with 87,815 miles on it from a deceased relative. He was an 88 yr. old guy and probably never drove it over 55 mph. The truck is in brand new condition inside and out except for a few minor scratches.
The truck has been in his garage since Nov. 2005 and has not been driven. I bought a new battery and it started right up with no problem.
The old guy always always used Havoline 10W30 oil I was told. So when I changed the oil I used it also. Now I read in the manual it calls for 5W30. Is this a big deal, or no?
Also, when I first crank the truck it sounds like a diesel starting. As soon as it gets running it sounds fine and drives very good. Why does it sound like a diesel? Is this normal?

Ive heard alot of people say that about the v-6. they sound like that from the factory and dealers have told me its unexplainable. im not sure if my 02 sounds like a diesel because i have exhaust work done and i cant hear much other than the rumble. as for the oil, i think it calls for 5w-20 but 10-30 isnt too heavy for the motor . as long as you dont go to 20w-50 or something like that ( ha ha ) you should be alright witht the oil.

My 99 uses the 10/30 as well with no problems.Changed every 3000 mies or so. I just rolled over 90k with no problems.As far as the diesel sound, my truck doesn't do it, but my buddies does.Mine is and everyday driver, and his sits for weeks at time. Been reading up on the noise, and the census is the same, everybody hears it, but it doesn't affect performance.

10W30 is fine.
I don't recall seeing 5W30 as recommended for the 4.2, but maybe I'm wrong.
Ford now says 5w20 is backwards compatible, but I'd stick with the 10w30 if that is what has been used.
As far as the diesel sound, not sure. Others have mentioned it, but neither of my 4.2 trucks has ever sounded like that.

The reason for the 5W30 was to meet the Govt emmision and milage standards, the 10W30 will be fine.

first 5w30 is for cold climates and 10w 30 is for those in warmer climates. Second the diesel sound actually has a cause. The hydralic lifters, after sitting for a while, allow oil to enter into the spring cavity making for a hard hitting lifter which makes for the diesel sound. usually after running for awhile the fluid is forced out and the lifter absords the push rod rather than slamming into it. however I have see cases where the oil remains. and the sound does not deminish.
