I bought my X from a buddy and he had the oil changed before I took ownership (dealership). I am getting ready to change my oil in about 1000 miles. I plan to install a fumoto valve (Maybe the Nipple one) This is a easy open close valve that works like a dream.No more un screwing the drainplug anymore. I had one on the Bike and loved it.
Anyway I already have a ford oil filter but need some insight on the oil. Under my hood it recomends 5w30 for the oil. What oil does everyone prefer? I was looking at the motorcraft semi synthetic but it only comes in 5w20. I dont mind using conventional oil but want something that will be good for my engine. I notice a lot of 5w30 and 5w20 oils are for high milage vehicles. It says on the container that it has stuff to help prolong the life of the engine. I dont want to add something that will hurt the beast either. Please let me know what you guys like to use and your results. Thanks in advance.

 

Welcome. I believe there was a change to use 5W-20 from 5W-30. My oil cap on the '02 says use 5W-20. I've used the Motorcraft synthetic blend, but now switched to Mobil 1 for towing. Nothing wrong with MC's oil.

What I did notice was that the Mobil 1 oil flows quicker at ambient temperatures, while the dino oil was more viscous. When it's hot, they're about the same viscosity. So, I think the synthetic oil helps it flow better when your engine is cold?

 

Did you notice any oil loss (between changes) when using either oil?

 

Yes. More loss with synthetic.

 

I use the Motorcraft 5w-20. I get the oil and Motorcraft filter at Walmart. I change every 3000 miles because I tow a lot.

I had a Fumoto on one of my old F350s with the 6.9 diesel and noticed it greatly restricted the speed at which the oil drained. That was with 15w-40 oil though. The 5w-20 is a lot thinner. Although with the oil drain plug on the side of the pan like it is on the V10 I would think a small amount of oil would remain in the pan since the Fumoto threads into the drain hole therefore raising and shrinking the drain hole slightly. But that could just be my OCD

 

I agree it will slow it down a little bit but I dont mind that. The valve doesnt actually thread past the pan either. They are some what vehicle specific and accoriding to Fumoto website they stop flush with the inside of the pan. I do agree it may raise it a hair. How many quarts does the v10 take?

 

Mine takes exactly 6 quarts. I also use the Motorcraft 5w-20 and Motorcraft filter. I Figure if ford likes it, so do I.

 

I had been using MC 5w30, but switched to the 5 QT jug which only comes in 5w20. I need to keep closer tabs on oil burn, as it seemed I did burn about 1.5 QT this last oil change. I don't drive alot of miles and do not tow. I change in the spring and fall with at most 5K miles.

 

I also use MC 5w20 with MC filter, have 177,000 miles with no problems or noises. I think my V10 is almost broken in.

 

MC filter and Mobil One 5w20 for me. Mine holds a bit less than 6.5 quarts. I start with 6 and add slowly until it gets exactly to the full line so I can easily track if any is used or burned between changes. Let it sit for 5-10 mins after running it to check for leaks and then check your level to avoid over filling.

 

10w30 quaker state or whatever the local lube guy has.

Never been too **** about it. Guess mine will only last 299K.

 

well i've never been a fan of the "easy valve"......... grab your wrench, crawl under truck (which you still have to do with the valve), put wrench on, bump with hand, unscrew...... i mean if you write it out it sounds like a whole bunch if pain staking work......

ok sorry i had to be a smart a** on that one. AND if for some reason you forget what size wrench it is, write it on the inside of your door, or some where under the hood (since you'll have to lift it any way to fill it with oil, or open your door to get in and out of the truck), then you can pop the hood, remind yourself of the wrench size, then revert back to the steps above......

been using 5w20 MC in both my V10's for over 7 years now, wally world usually has it in stock, comes in 5qt jugs, or cheap by the case as well. i use a Napa Gold filter (also WIX and CarQuest same company), mainly due to i get them delivered to me at work (saves gas on the trip to go get them), and they are the same price (for me) as the MC filter at wally world.

you can name off many brands of oil, MC, Castrol, valvoline, Mobile ect ect, most people will say they "never had a problem" or "it provided better protection".......this is usually based off a buddies opinion or their engine not blowing up after they switched brands...... oil is cheap protection for you're truck. you don't have to take a loan out on some high dollar royal purple or castrol "edge" at almost $9/qt for great protection out of oil.

 

just make sure your oil filter has the anti-drainback valve in it. that's the main reason i stick with the MC.

 

What does the anti drain back valve do? Sounds like a check valve or something. How do you know if it has one? Also, how do you convert your oil cooler from it's stock configuration using coolant from the radiator to a stand alone oil cooler with fan and will I see a drop in temps?

 

The Fumoto valve only requires a wrench the first time installed after that it is a simple 1/4 turn of the lever.
As far as oil goes, A lot of you guys are running 5w20 but not saying synthetic or conventional. If I am going to be losing oil with synthetic it almost sounds safer to go with the conventional. It souns like I can either way 5w20 or 30.
