This is the first thread I've posted on here, but here it goes! I just purchased an '06 F150 STX with 35000 miles on it. This truck looks like it was extremely well taken care of. My question is this. I have no clue what type or brand of oil was used in this truck. Is it going to matter what brand I go with or if I go with a synthetic? Just want to make sure to get it right as this truck has to last me a long time!! Thanks for any help!

Not sure if it matters, but my truck has the 4.6 V8.

 

I would go with the Motorcraft 5W20 oil (Semi-Synthetic) and a Motorcraft filter. You can get them at Walmart. Its cheap, what Ford recommends, and great in the truck.

 

I would run what ford built the motor with
I use Motorcraft 5w20 with a Wix filter

 

Or look for a coupon from a good Ford Dealer and just have them change it. They usually do the normal checks to and tell you if anything else is a problem. Of course you can just refuse anything else but it's good to know. I used one for my old truck last month, $19.95 for a coupon oil change, $70. for some other regular stuff including fuel filter and some adjustments, but it was worth it, they tweaked and lubed a bunch of little things including my stuck parking brake pedal.

 

I like MotorCraft 5w20 oil & MC 820 S filter. Get 5qt. jug for $11+ & filter for $3+ at wall mart ( 7gts with filter ) I use WIX filters in my non FORD cars. Local FORD dealer does the $19.99 oil & filter change & fluid top off. That's $19.99 no tax, no supplies or disposal fee, prices differ but its a good way to meet the guys at your local dealer that may help you down the road.

 

i too have a 2006 stx and love it mine has the 4.2 i got mine last march with 32000 miles and have 41000 with no problems

 

yep, stay with motorcraft products!!!

 

Mobil1 oil and filter, can't go wrong. Motorcraft?????only when thats all you can find.

 

Yep, Motorcraft is one of the best oils on the market. Use it with confidence.

 

based on what?

 

Thanks for the huge response everyone! Motorcraft seems to be the overwhelming choice here. Probably what I'll go with. Thanks!

 

Based on Mobil 1's ads.

I never understood how one could go the Mobil 1 route and say Amsoil is too much when it is only like 2 bucks more a quart. After discounts, you can get Amsoil for the same price.

I use motorcraft. Based on ..... 10 years seeing the insides of Ford engines looking perfectly fine on motorcraft. Less money, good protection.

 

I am trying Penzoil Platinum and I'm impressed so far. The engine seems quieter and runs alot smoother.
