synthetic oil

Pg. 94 in our 2000 f53 Owner's manual specifies Motorcraft SAE 5W-30 Super Premium Motor Oil. I followed their specs then after logging 10,000 miles on our coach I switched to Mobil 1 full synthetic which I continue to use.

Here's a link to a site that may shed a bit more light on the use of 5W-20 vs. 5W-30 discussion.

If I'm not mistaken the only reason they use 20w is to get better mileage.

If you are running hard I would see no problem (might actually be better) with a higher Viscosity oil- we ran it all the time in our heavy equipment with out an engine failure (30 years) . But what would I know I only got 10,000 hours out of my equipment and 500,000 miles out of my old 7.3 Ford diesels.

JMHO,

Ford V10's are not and never have been subject to any sort of mileage standards whatsoever.

I wouldn't change to a different oil if someone gave it to me. The oil spec'd will give you the best performance, why chance serious problems with something else?

Triton V10's called for 5W-20 to at least 1999. Nothing changed except the oil cap!

Will full synthetic be ok: YES
will the higher hot weight be a problem.....

I am not sure.. HOEVER.. with synthetics, they do not respond to heat like dino oil.. basically it's XX weight the instant you put the key in the ignition. I doubt it will be a problem...... Epically if the Ford has some millage on it.

That said: The rig below.. CHEVY powered.

I'm curious to know how much of a increase the mileage really comes out too. I'm not sold on name brand high dollar lubricants because I run our cars well over 200K on less expensive oils and filters. I've read everything anyone else has and don't see the need for spending the extra dollars, and by the way I don't drive all that easy. Engines have much closer tolerances now so oils can be thinner also. Not to say if you like the synthetics not to use them as they are good also.

I run Mobil 1, 5-30 Extended service(Gold Cap on the oil bottle) synthetic in my RV, cars, motorcycle, riding lawn mower and to lube my pellet stove in my stick built. It's a outstanding product I swear by it!

How much of a deal are you getting? Mobil 1 5w20 is usually 21-25 for a 5 quart jug a at Wally World.

Been using Mobil 1 5w-30 since our coach had 10,000 miles now has 89,000 absolutely no problems.

The 5w-30 won't harm your engine

Good luck & Safe travels...:)

P.S. The reason Busskipper gave for Ford recommending the 5w-20 is correct--better fuel mileage, but you'll never see any fuel mileage increase from using the 5w-20 oil.
