Engine oil.
Curious what others are doing about engine oil in their Ford V10. Synthetic or regular? Viscosity? Brand? Oil change frequency.

Most vehicle mfg's recommend regular oil at certain mileage intervals. If you want to use synthetic oil that's fine, but vehicle mfg's won't extend the mileage of service intervals.
For warranty purpose stay within.

I pretty much follow what the 2015 Ford owner's manual says and that's every 7500 miles or every six months. 5-20 or 5-30. Don't care about brand as they all come from the same bucket, just the ratings. I buy what's on sale or the cheapest. Regular dino oil and Wix filters as they're reasonably priced. I'm not anal about oil because I have yet to get rid of a vehicle because of a worn out engine (forget the Vega). Figure if I can get 250K out of them and then sell them, that's good enough for me.

In my Harley I switched from reg oil to synthetic and saw about a 10 degree drop in engine running temperature. Running it in all three holes, 10 degrees in Phoenix is important. That being said, we use synthetic in our Tundra and our Jeep and have never had issues. It may not be needed, but, it can't hurt and does a better job of protecting the engine in our high heat. Also towing a TT can put additional stress on the vehicle. I do keep changes to mfg suggested interval.

I use Mobil 1 synthetic, a high quality Fram filter and replace every 4,000 miles. The owners manual is for an E450 van. Seeing as it is under an almost capacity load everywhere you drive it, its hard on the engine. Oil is relatively cheap in comparison to high costs of repairs. I dont risk it, the oil change is simple and can be done yourself in 10 minutes.

X2. You said it all re: the oil. For the filter maybe use Motorcraft filter if you are under warranty.

And stick to 5W-20 per FORD. That engine has close tolerance bearings which have been known to fail as well as clogged oil ports with heavier weight oils.

I change oil in my vehicles every 5K miles (makes it easy to remember). Unless this thing has a bad leak, I wouldn't think of using anything but Synthetic. I'm a Valvoline guy, but I think if you stay with any of the major brands you'll be fine. But as others have said, the most important thing is to change the oil and filter regularly.

I've had great success running conventional oil at 5,000 mile oil + filter change interval. Older stuff (pre 1990) used 10W-40, 1990-2010ish 5W-30, now they call for 5W-20.
My 2013 VW Diesel calls for sulfur-free synthetic (only available at the dealer) @ 10K miles.
So, first see what the manufacturer of the vehicle call for and make appropriate adjustments for your climate and driving habits.

I pick up a Motorcraft (Ford) FL-820S Oil Filter and 6 quarts of Motorcraft SAE 5W-20 Synthetic blend Motor oil (per spec) at Walmart for less than $30 and change it out every 5000 miles.

Who actually goes 5k miles before an oil change, and who changes the oil after 6 mos when you've only driven maybe 1000 miles, or even 500 miles ?

Yep on both parts. They suggest both for a reason...and it's not to sell more oil.

It would depend on your usage. If your rig sits more than you drive it, like less than 3,000 miles per year, I would use Quaker State 5w-30 conventional. You should change the oil once per year regardless if its driven or not, conventional oil these days is good oil, cheaper than synthetic if the unit sits. RV motors are magnets for moisture when they sit in shaded, damp campgrounds. If your like me and hammer the daylights out of the motor, A/C running, stop and go traffic, running flat out on the hot summer days then 100% recommend Mobil 1 5w-30 in your gas motor. Had a class C and those motors / trans run very hot.

Use 0w-30 mobil one, Bosch or Purolater One filter.
RV is on the road 6 months of the year and then is in a RV park for the other 6. I log about 5-6,000 miles each year.
Change the oil every 6 months and the filter once a year.
