Recommend oil for a 2000 Navigator please.

[JustinH]

Hi Guys.

My mom has a 2000 navigator with about 50k on it. She religiously takes it to the dealer for service and they change with motorcraft filters and motorcraft oil. I bet they put 5w20 motorcraft oil in there (not bad oil).

Anyway, out of the blue she calls me up and asks if I will change the oil in the truck for her. She also says something about mobil1 because I use a ton of it on my other vehicles.

Anyway, what oils do you guys recommend? The motor is a 5.4 DOHC v8.

Right now I'm thinking either 5w30 mobil1 with motorcraft filter, or 0w40 Mobil1 truck and SUV oil aka Delvac 1.

Thanks,
Justin

Take your pick of the following;

Motorcraft 5w-20
Chevron Supreme 5w-20
Havoline 5w-20
Pennzoil 5w-20
Castrol GTX 5w-20
Mobil1 0w-20

You're in NY so your climate is close to mine. Look at all the UOA of with 5w-20 and Ford modular motors and you'll see excellent results. Even in vehicles towing heavy loads the Motorcraft 5w-20 produced excellent results.

I'd say stick with what the dealer has been putting in(which is almost certainly 5w-20) or, if she really wants Mobil1, go with the Mobil1 0w-20.

mikep summed it up nicely, any dino thats meets Ford WSS-M2C-153H, or if you want the advantages of a full syn M1 0w-20.

If I were you I would stick with Motorcraft FL802S filters and Motorcraft 5W20 oil. They are readily available at Walmart, cheap and proven performers.

Nothing wrong with Mobil 1 (great stuff) but you already have a winning combination.

Our Navigator has about 125K on it with the Motorcraft oil. Runs great.

With this monster, you probably want to do all you can to improve the gas mileage.

A dirty air filter can penalize you quick on this one, too.

I'm not sure a 0W-40 or the Truck/SUV is really a good idea. It might cost you a couple of tenths mpg. The Navigator seems pretty happy with 5W-30 or the 20's. That's just a theory. I've never run anything "thicker" than 5W-30.

If she plans on keeping it and drives a lot, I'd probably go with the Mobil 1. Our best mpg is 15.3

With all the great OUA's the Motorcraft 5w20 is turning in with the Ford modular engines I'd say use that oil ad a Motorcraft filter. Both are easily found at Walmart or Advance.

'Splain to mom that the Motorcraft 5w-20 IS a synthetic blend, a bunch cheaper, and a darn fine oil. If money is no object, then by all means use Mobil 1 0w-20.

thanks guys. I told her to keep taking it to the dealer, and keep letting them put 5w20 semi syn in it. I think the oil changes are like 22 bucks, and it would cost me 15 bucks in supplies to do it, so I would rather let them do it.

Maybe, but where's the fun in THAT?

It's good to have a Ford dealer you can trust. I'm sure mine bills for the Motorcraft, but I'd bet he put's the cheapest bulk available in. I just buy my own. That way I know, no matter who changes it.

Some of these guys pump the cheapest bulk that'll work and bill you for a Ford spec. #

I suspect many dealers of pumping the cheapest 10-30 bulk in everything.
