Synthetic Oil choices?? by bda54

Can anyone recommend or compare Redline lubricants to Amzoil for the entire driveline of my '03 Dakota Quadcab, 4.7, AT, 4x4. I live in Minnesota and drive it primarily for work, but use it for hunting, but no heavy off road use. Also which oil filter would be best for use with the synthetics? I've heard Redline lubricants are spendy, but how spendy compared to Amzoil?

Anybody have some real world numbers on a HO engine and a FFV engine?

I just checked my receipts when I purchased the RedLine lube for my driveline. (both differentials, xfer-case and manual xmission) I paid $8/quart.
 
The RedLine PowerSteering fluid was $9.50/quart.
 
When considering this, one must consider the VALUE and not the initial cost. For me, my rear differental was saved from self-destructing when all the fluid came out. (but RedLine leaves lubricating residue.)
 
Also, my powerSteering no longer needs 5-minnutes of warmup in the winter before it starts to work. (-15F)

Thanks for the reply. Do you know of any independent testing comparing Redline lubricants to Amzoil or other synthetics that can be checked out? I had forgotten to think about the power steering fluid.

I am not aware of an "independant" testing. Amzoil is somtimes marketed thru individuals who often make claims that even Amzoil does not acknowledge.
 
Keep in mind that RedLine uses 100% pure synthetic polyol ester basestock. This is expensive stuff that most off-the-shelf oils do not even consider using. Competetive Racecar teams use RedLine becauese it works. (reguarless of what the stickers may say on the OUTSIDE of the car!)
 
Here is webpage for RedLine ==> http://www.redlineoil.com/default.asp
 
The polyol ester basestock is used in extreme-duty conditions (Jet turbines, aerospace...etc) and may be more than the average driver needs in his road vehicle.
 
I beleive that Amzoil may also use some polyol ester basestocks... but over the years I have become put-off by their marketing (pushiness).
 
The Federal law was changed in recient years to allow manufacturers to CLAIM an oil is "synthetic" even though they contain petroleum-based oil. (MOBIL1, SYNTEC...etc fall into this category) These are not The polyol ester basestock!

My young son and went to the Mopar Car Show in Carlise two weeks ago. Leaving Rochester, New York on I-86-US17 to US15 south, my '03 Dakota (Club Cab Sport, 4.7, 545RFE, 3.55 LSD, no mods) got 23.92 MPG on Mobil gas. That included 41 miles of town driving.
 
With the exception of about 1.5 minutes of actual passing, I kept the cruise control set at 62 MPH all the way to Harrisburg on US15. On 55 MPH highways I stayed at the speed limit.
 
The return trip, however, was 22.71 MPG on Amoco with 10% ethanol.
 
Regards,
Dusty

Bpeebles,
 
I believe your refering to group IV base stocks. Mobil 1 uses group III, which I believe is partially synthetic. Or is my memory bad? Too lazy to look it up
 
What's new up there in the north country?
 
Bests,
Dusty

Good to hear from you Dusty - yes, the polyol ester basestock is also known as "Group IV".
 
The "North country" has seen rain almost every day for about 2 months. I guess the folks that have been cryin "global warming" will have to come up with a new story. So far they have cried "global IceAge" in the 70s and "hole in ozone" in the 80s.
I cant wait to see what they claim is coming up next... LOL

3 Dakotas (1-03 2-05s) Commute & Highway by remav
Aug 15, 2008 (10:46 am)

My commute is a very good mix of driving of about 22 miles.
9 miles of city/paved hilly country roads 25mph to 45mph, no stops
7 miles of state routes 45mph to 55mph with stoplights av 1/mi.
and 6 miles of flat freeway, 55mph to 65 mph.
 
2003 2WD Sport Ext. Cab V6 3 spd Auto could NOT get 20mpg on this. 19+ multiple times really trying, but usually 17.5 to 18.5. Highway driving it would pull 22.
 
2005 2WD Club Cab SLT V8 5spd Auto would get 20mpg on this commute. Jersey to Pittsburgh holding steady 65 I got 24 going out empty, and 22 coming back with 1000 lbs of computer hardware in the bed. K&N Air filter is only add-on.
 
2005 4WD Quad Cab V8 5spd Auto Laramie has held 19mpg on the commute, but any side trips in town & it quickly falls to 16.5 to 17.5. Long drives yield 20-22 highway.
 
I was impressed that the V8s did as well as or better than the '03s V6.

Remav, your results are quite typical.
 
I remember some years ago when the 4.7 PolyTech motor was introduced there were a couple of magazines and the notoriously inaccurate Consumers Reports that proclaimed the 4.7 a "thirsty" engine. As most long term 4.7 owners will testify, this engine takes a while to break in, and once it does it delivers superior gas mileage when driven sanely.
 
Now I've found that if you have an aggressive right foot, gas mileage will drop precipitously. But, like many others a sedate driving style returns numbers equal to if not better than the 3.7 V6. In the case of V6 equiped Dakotas, be mindful of the rear axle ratio. Many of them are sporting the 3.91 ratio. I've driven a couple of these versions and they have surprising power. But that's in part because of the 3.91 gears in the rear.
 
I've found that I do better than a couple of Nissan Frontiers and every Canyon/Colorado owner I've ever talked to. Of course, some is pure denial, especially since these are Dodges.
 
My best so far has been 23.92 on a 700+ mile trip, empty except for passengers, average speed 63 MPH and hilly territory.(2003 Club Cab Sport, 4.7, 545RFE, 3.55 LSD, P255 70R 16 Michelin LTX M/S tires.)
 
Bests,
Dusty
