High Mileage Recommendation

I second what Schmoe recommended.
I'll differ from above. Given the vehicle will not be driven very much, and then not very hard, I would use a high mileage 10w-30 oil since it runs a little thick and change it once a year. There is no need for Synth in this application. As far as Brand of oil, any of the major oil brands should be fine.

don't forget guys..this car will be driven in Florida..where it will never see below 60 degrees. I wouldn't recommend syn for a car this old and mileage this high unless auto-rx. since it would take 2+ yrs for auto-rx to work in this engine. I would recommend a thick 10w-30 high mileage oil like Pennzoil high mileage, it's about the thickest high mileage you can find.

Maybe one of the blends then? I'm slightly afraid of a full syn causing leaks, but again the car will sit for about 7 or 8 months out of the year. Temp will be fairly consistent where the car will be (Fort Myers). OTOH, Mobil 1 10w-30 is the only M1 that says "compatible with seals in older vehicles." I think Pennzoil is good stuff based on what I've read here, but neither do I subscribe to the "thicker is better" school of thought. Right now I'm leaning in favor of the Mobil HM Blend in 10w-30.This car is likely to see alot of short trips with lots of cold starts. The standard Pennzoil 5w30, which the car is spec'd for, will work best, IMHO. Any oil that's heavier will just gunk up the engine needlessly; the 5w30 will handle the heat just fine, thenk-you.
The early 4.6L from ford used to burn oil through the valve seals like a biotch. I know, I had a 1993 Grand Marquis, and after 100,000 miles, the seals were rock hard and I would have to add a quart every 700 miles. I would lean to the heavier weight oils (maybe Castrol Syntec 10W-40, or Mobil 1 5W-40 SUV oil) in order to control any oil consumption issues.
quote:my point exactly. lots of cold starts and lots of short trips = fuel dilution. if you use dino 5w30 pennzoil, that oil will shear to a 20wt with the heavy fuel dilution which will sludge up. I'd rather have 10w-30 in 60 degree and up temps anytime

quote:Wait a minute. We need to be clear about what PART of Florida he's talking about. I believe NORTH Florida to be more oil-challenging than south. We get almost as hot in the summer up here as they get down south, but in the winter, we routinely get temps, in the morning at least, that approach or occasionally dip below, FREEZING. If the car will be sitting in Tampa, Orlando, or Miami you can use 10w-anything and not worry about it. If the car will endure winter anywhere between Pensacola and Jax, the onwner may want rethink the 0w/5w/10w choice. IN any event, however, this won't be ultra-critical.

For one, that is a great, tough engine that doesn't show much wear in general. With 172000 miles, being a 91 and then mostly hot temperature operation, a 10W-30 may prove to be a good choice. My uncle has run Valvoline 10/30 in his 94 Mark VIII 4.6 for years in Minneapolis with no problems. Florida's temps will even be better with a 10W-30. For the ease of it, using Mobil-1 SS 10W-30 once a year would give great protection, especially in the warmer temps, or even in cold conditions. I used it (M1-10/30) in a Mark VIII 4.6 and had great results! For $19.82/5qt jug, and once a year worry free operation, it would be a great choice. IF, you are concerned with small leaks and seapages, etc, get the Valvoline Synthetic MaxLife 5W or 10W -30. Although with very little driving, it may not get an opportunity to work into the seals, it has been the only HM oil to stop leaks/seapages for us. Get the synthetic ML and still change it once a year. Either will work just great! How about the transmission fluid? FL hot temps may cause more stress on that than the engine. The high temps can be tough on ATF. Good luck! A winter home in FL must be fun!!

Actually dad's previous home is now for sale, if anyone wants a beachfront condo near a golf course and fishing.... Dad says you don't have to shovel sunshine. ![[Big Grin]](images/icons/grin.gif){kind=icon}
I plan on getting the trans flushed and changing axle lube, antifreeze, belt, hoses, brake fluid, etc, before I go. During the hottest part of the year, summer, the car will be in the garage anyway. Thanks for the input everybody!
Long story involving deceased relatives and inherited cars but here goes. My sister and bro-in-law are giving back to my dad a 1991 Lincoln Town Car that he gave them several years ago. The ol' 4.6 SOHC is still happily chugging along at 172,000 miles. Dad plans on having me run it down to Florida on the Auto Train (cuts 900 miles off the trip) to keep as a spare at his winter home, where it will sit a lot and probably get changed once a year with not a lot of miles. I will most likely not have time to run 2 ARX cycles before I go, nor do I trust anyone to follow up properly down there if I did even one. My bro-in-law takes decent, but not exceptional, care of his vehicles. I will use a Motorcraft 820S filter and it calls for 5w-30 oil (or should I use 10w?). The 5w-20 I think is only recommended for 92+ .
Now then:
Valvoline Max Life
Max Life Synthetic
Valvo DuraBlend
Pennzoil High Mileage
Castrol High Mileage
Mobil High Mileage Syn Blend
Mobil 1 and fugghedaboutit
Whatever is cheap and it doesn't matter
Other ????
Your votes please.
Thanks.
[ June 03, 2004, 12:47 PM: Message edited by: JohnnyO ]The car's a '91 Lincoln. Personally, I couldn't justify the expense of $5/qt oil into this particular ride, but everyone's wallet is different. Hi-mi oils solve seal leakage problems, helpful if leaks are present. If they're not, than more expensive hi-mi isn't really necessary if there's no leaks to "fix." I'd go for an inexpensive 5w-30 (or 10w-30, although it calls for the former).
I would think that a HDEO like:
-Delo 400 15W-40,
-Shell Rotella 15W-40,
-or Shell Rotella T Group III 'synthetic' 5W-40 would be worth looking at.
The robust additive package in Diesel engine oil is supposed to be great for garage queens.
The viscosity and the additive package make sense, as does the cost, since it mnight make sense to change once per year,.......or shortly after arriving and just before leaving each year.
I'd go for free Max Life and only if it's free.
Well, dad got the car last weekend. Oil was just changed, there is a sticker on the windshield from a service place saying Castrol GTX 10w-30 was put in. The filter is black but that's all I can see from up top, I don't know what kind it is yet. I'm leaving for FL in a month, depending how many miles my dad puts on in the meantime I'll either put on a Motorcraft filter and add a quart of Castrol or change the whole thing out and put in a 10w-30 blend. It doesn't look like it's leaking as far as I can see. Trans fluid is nice and pink. I'll change the coolant soon too.
