I need to change the oil, what would be the best oil for the ford 460 with about 85K on it. I saw someone mention Zinc, what does does do and should I add it ? also is it possible to change just the filter and add a quart between oil changes ? and with that said how often should the oil be changed.
also, what about the Tranny change, when should it be changed and how often.
Thanks

We have a 1994 Pace Arrow and always use Valvoline 10/30. Check it daily when crossing country. Check it in the am - add about a quart every 1,000 to 1,200 miles. Change the oil about every 4,000 Interstate miles. Used Valvoline for 5 + years. Also use Fram filter. Ours is a V8 460 FORD also.
We have added to the transmission fluid but never had it changed. Can't help you there.
You have a good Rig, hope you enjoy it.

Zinc has been removed from engine oils long ago due to EPA regs. About the only oils still having adequate zinc levels are those intended for off road use such as Valvoline racing oils.
Since newer engines all have roller cams the no zinc content isn't that critical. However, for older engines with flat tappet hydraulic lifters its best to use a zinc additive with every oil change.
This is the link to a zinc additive I've used with good results:

Concerning engine and transmission intervals, I always change every 3 to 4,000 miles on the engine oil. I always either do a transmission
flush or at least a drain/refill every year. Thats considered overkill but I've never had any transmission problems with either tow vehicles or motorhomes over the last 20 plus years.

with the tranny I have No idea when or if it has ever been changed in the past, when you say a flush and fill, are you saying you simply drain it and fill it with out changing the filter ?
how many quarts of engine oil does the 460 hold for a RV ?
Thanks

Engine holds 6 quarts of oil. You may still have a mismarked dipstick that shows full at 7 quarts. If you have the old dipstick, Ford has the correct replacement. You E4OD tranny holds 16 quarts of oil, if you drain the converter, along with removing the pan. Remove the rubber plug in the bottom of the bell housing and bump the engine over until you see the drain plug in the converter. There are two plugs, 180ยบ apart.
Any good 10W30 or 15W30 oil will meet your engine needs. Do not use 10W40 unless its synthetic. 10W40 conventional oil has viscosity improvers in excess of 17%. 10W30 conventional oil has viscosity improvers at about 11%.

We have moved to synthetic 5W-40 Rotella for both high mileage Ford and Chevy Big Blocks that we drive as well as for the lawn mowers to diesel engines we change. Higher zinc was one reason. Did use WM 10W-30 full synthetic before adding the diesels to the mix that needed changing.
The cost difference between dino and synthetic oil today is nil for once a year oil changes.

Many of us 460 owners use Rotella 15w40. Can be found across the US in WalMart. Don't be surprised to see how dirty the oil is when you first switch to a diesel oil. Rotella really cleans out an engine.
Up to you when you feel you need to change. Some say every 3K others 7K. Me I use a K&N filter, my rig sits most the summer but is used all winter. Before the winter I do a complete change, in the spring I drain the oil and replace with fresh.
Tranny change for me is every 35K.
Other biggy to be aware of is flushing your brake fluid. That should be done every 2 years, most owners fail to do that.
Also the fuel filter passes many gallons of gas threw it at 5-10mpg.
Another one to be aware of is the parking brake. There is ATF in there also that needs to be checked. All of the above is in the forum if you do some searches on.

Hmmmmm. IMHO I would use the weight oil and make changes as recommended in the owners manual.

Sounds logical, but a few things to remember. A 460 is a flat tappet engine that requires a zinc or other high lubricant in that high heat area. Oils have changed since that 1992 owners manual was written.
Second, a class A is an extreme use vehicle, make sure you use the guidelines for an extreme use vehicle if you are using the owner manual. Otherwise find the extreme use guidelines on the net.
