Oil Type for Ford V10?

[Menander]

I have got a 2001 Fleetwood Bounder 32H with a Ford Triton V10 with no owners manual for the chassis. Has 15k miles on it. What engine oil grade would be best ?

[Menander]

Thanks!

5w-20. book says and so does cap on oil fill.

We use 5W-20 on our 2000

Glad you found something that works for you.

But any time an engine uses or loses a quart in 100 miles, you should be looking for the reason. Most likely it is a leak somewhere.

Contrary to what you are implying, thinner oil lubricates better......but wasn't practical to use in a "dino" variety because it would get even thinner when hot. Enter synthetics which hold their viscosity better over a wide range of temperatures. 5-20 synthetic should be just fine.......for any healthy engine.

Contrary to what Ford says, I found that 5-20 was too thin....adding a quart every 100 miles or so. Since then....my 2001 has run 10-30 fossil. 54000 miles, change oil every 3-4000. Never seems to use a drop between changes and never any engine problems.

"They" all want us to use a very thin oil...to improve their "fleet" numbers for the EPA. Like when buying a pickup....the dealer wants to you buy, say a 302 cid....and actually cringe when you want a 351 cid for towing. All for the gov't mandated "fleet" thing...at our expense.

My 2004 MY Fleetwood Bounder 36S Class Motorhome on Ford Chassis (Ford F-53) Triton V-10 owners guide says use 5W-20 Premium synthetic blend motor oil.

X2 on the 5-20 as recommended by Ford for our 2001 F53's V10...

Yes. What I've run in this coach, a 2010 and our previous, a 1999. Both on F-53 Chasis, both with 0 problems.

I'd go with full synthetic, 5w-30. I am proud to say I DO think Supertech oil from Walmart is absolutely fine stuff. Meets all the regulations and has fine reviews from bobistheoilguy.

I use Rotella T-6 Synthetic.
It appears to be rated 5W40.
It will hold it's viscosity a bit better when HOT than a 5W20.

v10 uses low tension rings for more mpg use only 5w20.

Again, thanks all!

The manual specifications for older V-10's has been changed. Ford changed the recommended oil to 5W20 about 2004. I had a 2000 V-10 at the time.

Many comments at the time attributed the change to an effort by Ford to improve MPG across the fleet. I used 5W10 Mobil 1 from 2004 to 2012 and 130k miles. No measurable wear on engine when torn down due to spit plug.

2001 F53 owners manual

(Assuming you have a 2001 chassis. 2000 specified 5W30.)

My thanks to you all!
