Hey Guys,
I know this is a old news subject from what I have read on here BUT! I am fixing to change my oil in a 2005 F 150 Super cab 4.6 L 52000 + miles and wanted to know what you all would suggest what oil to change it with. I just bought the truck from a ford dealer in May and was not told what the best oil is to use.
Like I have read before on here the oil cap and manual say 5-20w , But it does not tell me weather to use synthetic or semi synthetic . So I would really appreciate you all giving me some direction to go.

Thanks
Keith

 

I and many others on this board buy motorcraft semi synthetic and I ALWAYS use the motorcraft fl820s filter. All that is available at walmart for around $17-$20

 

i would base my selection depending on my climate on where i live. for example i live where summers hit 119 degrees so i need a thicker viscosity oil like w30 or w40..in summers i run 10w40 and rest of year 10w30..if its cooler in your area a lighter oil will work fine..5-20w is almost like water but it'll work. hope this helps.

 

Ford recommends 5w-20 period. Use the recommended oil.

 

Thanks jethat and gordo.
Since I did buy and extended 3 year warranty with FoMoCo with the thing I guess it would be a smart thing to do is use what is recommended by Ford. Am I wrong?
I live outside of Dallas Tx and it does not get as hot as where you are gordo. But I will use the motorcraft oil filter. I have read on here that Valvoline is just as good as Motorcraft as far as oil. What would you use?

Keith

I think I will go with Motorcraft

 

yea no problem..i use the motorcraft oil filter..ford is gonna sell you what ford makes..enjoy your new truck

 

I have used MC 5W20 Synthetic Blend and MC Oil Filters on my '01 XLT 5.4L, '02 Mustang GT and on my '07 STX 4.6L with zero issues. I also use MC Oil filters on my '68 Ranchero and '94 Lightning.

You can't beat the price of MC oil and filters at WalMart...

 

If you go to Wal*Mart, the best deal there is the 5 quart jugs of Mobil1.

 

i use ford oil and fl820s filters. unless mobil 1 synthetic is on sale, but i still use ford filter.

 

Please explain what you base this logic on!

Welcome Kieth...what a question to waste on your first

Since you asked in here, MC oil and filter will unanimously win out the majority vote. It's the best bang for the buck and you certainly can't go wrong with it. There are other (and IMO, better) options, but you gotta be careful with those. Best thing you can do is make an educated decision that YOU are happy with and stick to it. Either way, not too many ways you can go wrong with a good oil these days.

 

hotter temperatures quicker break down

 

Thanks everyone for the good info. Motorcraft synthetic blend 5-20w and motorcraft fl820s oil filter is what I will use

And thanks for the welcome Galaxy.
I guess I am still a green horn with only 5 post

Once again THANKS

Keith

 

But thinner oil runs cooler than thicker oil (less friction) - so you have a wash there, Gordo. You are about 20 years behind in your understanding of oil and engine technology. 10W-30 and 10W-40 is for old school pushrod motors with a lot sloppier clearances than the modern high tech OHC engines.

Use the recommended weight oil. Doesn't matter what brand and type you use as long as it meets Ford 930 specs. However, the Motorcraft semi-syn is the most cost-effective oil to use, all other things being equal. There is no need to use a full synthetic unless you want to extend your drain intervals. The fact that the Motorcraft oil is so cheap at Walmart makes it almost a no-brainer.

Oh yeah - Gordo, Ford does not make Motorcraft oil. Last I knew, Conoco makes it.

 

5-20, Motorcraft Blend.

 

you see the keyword is RECOMMENDED. just because someone recommends a brand or weight doesn't means you have to use it. YOU go by what works. 20 years ago does not make a difference. HOT IS HOT COLD IS COLD. your gonna want the least friction as possible. The Ford engine is developed to give you the best possible output within a temp spec. why would you want a lighter thinner oil which is giving you the least protection against friction. when your engine coolant is at 210 degrees and cylinder head temp is 231 degrees? thats a hot engine! my understanding is my 05 f150 5.4 is supposed to be running at 198 degree coolant temp and 212 cylinder head temp.
