[BIGNELSTER]

Help me out on this issue what's recommended
For such milage?
Thanks

There were so many 'Oil Wars' on this site back in the day....this kind of post was almost banned!

LOL.

BTW: I've always used MObil 1 regardless of my vehicle's mileage.

[8UWITH6]

Been running Motorcraft Synthetic Blend 5W30 in mine, only 41K miles though.

Its really your preference. The black car that we just picked up with a lot of miles the previous owner states he has been running Royal Purple full synthetic but I will probably run something different in it because of the mileage. Havent decided yet though.

[BIGNELSTER]

LOL,
I just changed my oil for the first time
Added 10-30 full synthetic pennzoil platinum,
Anything against this?

Amsoil FTW!! Changed every 10K, only changed the oil 3 times in the 2 1/2 years i have owned it

Most currently manufactured oils are fine....the key is using a good filter, checking the oil level frequently and changing it on a regular schedule!!:beer:

I also use a Filter Magnet to trap ferrous metal "fines"....cannot hurt!!:shake:

I agree...

It's hard to beat a proven winner like Mobile 1....

It's hard to beat a proven winner like Mobil 1....fixed it for you

@ the OP: the BEST oil is the one that makes you feel all warm and fuzzy.

Pennzoil Platinum
Castrol Edge
Valvoline Synpower
Motorcraft
Royal Purple
AMSOIL
Mobil 1
Fuchs Titan
Motul 300V
Eneos Sustina

...the list goes on, but you get my drift. There IS no one "best" oil.

@ BIGNELSTER: 10W-30 is a little thick for a DOHC engine. You really want the first number as low as possible to allow better flow to the heads during cold starts. That doesn't mean sub-freezing, it means anytime you start the motor when it's not at operational temp. 5W-30 or 0W-30 would be a better choice.

Nope. Should be fine.

[RF Overlord]

The black car...has been running Royal Purple full synthetic but I will probably run something different in it because of the mileage. Why? What difference does mileage make? Royal Purple is an excellent oil, albeit a little pricey, but there's no reason to switch just because it has high mileage. BTW, what do you consider "high"? Mary's car has 177,xxx and I've run the same oil for the last 70,000 miles. Marauderjack just reached 250,000 and I think he's always used the same oil.

[tbone]

For the money, Mobil 1 is the best you can get.

[UncleLar]

New fresh oil....
Just messing with ya,personally I run 5-30 Motorcraft Syn Blend & Motorcraft filter with 107K on my DTR,
it can get pretty hot here in AZ. 112 @90mph with the A/C up a mountain gets the
coolant temperature gauge to start moving up pretty good.

Full syn is fine to use in a high mileage vehicle IF it's been used already for some time. When you take a regular or syn blend high mileage vehicle and add full syn to it there is a high chance stuff could start leaking only because the oil is just a lot more finer/thinner.

On a high mileage vehicle with not knowing the maintenance history I would run exactly what the manufacturer recommends to start out with.

Synthetic oil is not finer/thinner. The molecules are more consistent in size, but they aren't a different size that those of conventional oil. What makes synthetic seem to "cause" leaks, are two factors: the first was an incompatibility between early synthetic oils and the elastomers used in the seals. That issue was solved in the early 1980s.

The second issue is that in an older engine that has been poorly maintained or abused, conventional oils form sludge which coats the by now hardened seals. Using synthetic oil can clean up that sludge and you'll suddenly have leaks. Continuing to use synthetic will eventually rejuvenate the seals and the leaks will abate, unless the motor is too far gone.

If an engine has been properly maintained and is in sound condition, there is no restriction on using synthetic oil.

do not change oil with less USED oil :shake:

[RF Overlord]

do not change oil with less USED oil :shake:Unless it's Valvoline NextGen (http://www.valvoline.com/products/consumer-products/motor-oil/conventional-motor-oil/124). :D

I'm switching to that in my DD.

[larryo340]

I got my MM in January with 125k, and it had a Royal Purple oil filter so I assumed it had Royal Purple oil. It now has 136K and I change the oil every 3K using Motorcraft 5W20 and a FL-820S. No noises other than a little chain tensioner noise for a split second on a cold startup after being parked all day or overnight. Should I switch to 5W30 ?

[MOTOWN]

Amsoil, and Redline are the best you can buy!

[JBeezy]

I'm a full synthetic user. Mobil 1 since I purchased it with 30k. It's at 49k now. Going to change it soon due to elapsed time

[GreekGod]

Since Ford recommends 5W20, that would be the weight to use. A respected ex-Ford engineer has gone on record as stating that the 5W20 is more or less Federally mandated for fuel mileage. He also stated that it does cause more engine wear than 5W30 does. Never use a 10Wxx weight oil, as the engine is designed to require the 5Wxx for cold weather start-ups and running.

Lots of independent testing produces many varied results.
Mobil 1 doesn't stand up well in head to head with redline, royal purple or Amsoil.

That being said, it is still a matter of choice, based on your needs and useage.

Bottom line change your oil annually or 10-20000 miles based on your oil Mfg. recommendations (not every 3000 miles).

IMHO:

My work van/trucks, get oil changes every 20-25000 miles with what is considered "Severe" duty, towing, heavy loads,,stop and start driving including many short trips.
I have used many synthetics over millions of miles in my service trucks including Mobil 1, Castrol and Pennzoil, I have had the best results, (fuel economy, lower operating temps, etc) with Amsoil.

Me, I run Amsoil Dominator Race oil 5w20 and Amsoil eao11 filtration in my Marauder
Changed annually at about 6000 miles. Mainly highway and drag strip use.

YMMV.

[nusbd]

122k is still low mileage for these engines if properly maintained. Good fresh oil, 5w20 or 5w30 depending on your climate and a quality filter changed every 3k to 5k is ok. Both my P71's have in excess of 300k, and we use quaker state or pensoil with motorcraft filters. cleanliness is everything, these overhead cam engines, with no replacable bearing inserts, are very sensitive to dust/dirt/sand.

[RF Overlord]

Mobil 1 doesn't stand up well in head to head with redline, royal purple or Amsoil. Can you show me where it "doesn't stand up well"? The first link is an AMSOIL-sponsored test, and the last is an Australian test where they use the one-armed bandit, which has been discredited by every legitimate oil testing laboratory as irrelevant for motor oil.
Bottom line change your oil annually or 10-20000 miles based on your oil Mfg. recommendations (not every 3000 miles).While I agree that this mileage is certainly possible, I would strongly urge anyone attempting to go more than 10,000 mile to have a UOA (Used Oil Analysis) performed.

More than you ever want to know about oil & filters.

[GreekGod]

Short trips in below freezing weather is severe service, and calls for frequent oil changes, regardless of oil type.

[Flbatfish]

My 2 cents. I did a lot of research and found that the Shell Rotella oils have retained a high zinc level (the oils are intended for diesels). I use the synthetic T6 in all of my engines (1930 Model A, Harley 1350, 4.6 single over head cam, and Honda GL1500). I especially recommend this oil if you have a push rod valve system. The zinc protects your lifters and cam. The zinc was removed from most car oils to reduce emissions. Even thou we have roller tappets I like the extra protection.

^^^^clarification^^^^

I have had done some oil analysis testing back in the late 80's early 90s when I 1st started trying synthetics
In my vehicles I experienced longer oil life in my trucks with Amsoil in them and had less harmful contaminates, better protective quality retention and remained in service longer than the ones I ran Mobil one in.
Not looking for an oil battle, I don't sell any of it except for marine use and then I go back and forth between RP marine and Amsoil marine oils.

But, I have had vehicles with 400k miles on them that always had minimum 25k oil changes, never leaked, smoked, knocked or died. One of those 400k trucks is still running around here. Who knows how many miles it has on it now.


I agree with the "whatever makes you feel warm and fuzzy" line.

Do some oil research on the net, make your own conclusions.



I drink Starbucks too:lol:

[RF Overlord]

Not looking for an oil battle,I'm not, either, and in light of your experience, I'm not suggesting you're wrong; I was just curious about your "Mobil 1 doesn't stand up well" statement as M1 enjoys an excellent reputation on BITOG and was my original oil-of-choice when I first switched to synthetics (I have since settled on Pennzoil Platinum).

I agree that for extended OCIs AMSOIL is the king, but I also believe that for more "normal" intervals (up to 10,000 miles), any of the top-tier oils will give excellent service and that the difference between them is negligible.

I guess I should probably state that I dont run oil any longer than 3000 or 3500 miles therefore buying Royal Purple would be a waste of money for my situation. However, I do run Royal Purple gear oil in my differentials. With the frequency of my changes it just makes sense for me to run the Motorcraft or equivalent synthetic blend. :)

I meant higherrrrrr mileage, not high mileage. Yes, 177K is nothing these days on mileage. There is very little difference in driving my 41K mile blue and TagAlong's 177K mile black.

I have heard of a lot of guys running the Rotella on older flat tappet engines such as the Turbo Buicks. I run Mobile Conventional 10W40 and add a 12 oz bottle of the Lucas Engine Break In Additive for added Zinc content in mine. Of course it gets changed every 2 years regardless of mileage.
