synthetic diff fluid

[Archive]

I am preparing to change over to Amsoil synthetic gear lube in the rear diff. Was wondering what weight everyone is using. Factory specs call for 75w-140. I talked to my dealer and he told me that as long as it is rated g-5 he will honor warranty. I use my truck for 100% towing and was wondering about the lighter weight lubes. I'm planning on using the same lube in front and rear diff. Any input would be appreciated.

Why do you want to change to a lighter oil? Most of the time you will see higher wear by using a lighter oil than a heaver oil.

You have less drag with lighter oil, especially in cold weather. With synthetic, which holds viscosity better at higher temps, and reduces friction compared to regular gear oil, you don't need the heavier stuff to do the same job.

I run Mobil 75W90 synthetic gear lube in my rig, cost $5. 50 a quart. I understand this is plenty adequate unless you do a lot of heavy towing, in the summer.

Horsehauler, If you always haul loads my recomdation would be to use the LE gear oil from Mag-Hytec. It's heavy duty and will work very good.

I changed the OE diff. oil to Red Line synthetic 75W140NS (No Spin. . contains NO friction modifier) when I installed my Mag-Hytec diff. cover 16 months ago, adding the required friction modifier as required/desired for my LSD. The '98 owners manual (page 150) states the following: "If you plan to utilize your vehicle to pull a trailer for a significant number of miles, reduce the potential for rear axle overheating by replacing the rear axle lubricant with an SAE 75W-140 synthetic gear lubricant. Mopar Synthetic Gear Lubricant is of this type. " As I do not tow or haul heavy loads a "significant" number of miles, I elected to switch to Red Line's synthetic 75W90 gear oil (contains 5% friction modifier) at the advice of Dave Granquist (Red Line tech. ). Last week I changed the gear oil in both diffs. using their 75W90, adding 2 additional ounces of Red Line synthetic friction modifier initially, adding two more ounces later to further tune the gear lube to the LSD. I had over 23k mi. on the 75W140NS gear lube when I drained it. The Red Line and Amsoil 75W90 synthetic gear lubes are both excellant choices for heavily loaded Rams. I was also told by Dave that 75W140 and 80W140 gear lubes will not disipate heat as fast as 75W90 gear lubes. I believe DC's reference to "reduce the potential for rear axle overheating" is due to replacing the OE mineral based gear oil with the synthetic. Roy (the owner of Mag-Hytec) recommends the LE-607 (I believe that number is correct) gear lube.

John, the flash point of Amsoil 75w140 is 396 Deg F. and the 75w90 is 338 Deg F. Thats 58 Deg F. difference and the 75w140 is only 1/2 the viscosity of the 75w140. (cSt @ 40 c is 89. 7 for the 75w90 vs. 176. 4 for the 75w140.
The LE oil has a flash point of 405 F. which is higher than the Amsoil products. It was designed for severe duty service in the big rig trucks. It contains Almasol, an anti- wear agent in addition to the other anti-wear agents normally used. The LE product reduces wear dramatically, which reduces temperature 10 to 50 Deg F. When temperatures are reduced this means that there is a reduction in energy, in this case the energy is fuel. LE does this by better lubrication and does not have to rely on reduced viscosity that gets its reduction from a thinner oil that could be too thin to do the job in severe duty applications.

DOOOOODZ...

As a Auto-Crossing, Power Shifting, 155+mph Speed Veteran, High Octane, GearHead... I've used a LOT OF PRODUCTS...

I think some of the More (Reputable-Poor Word Choice later revised as follows) Main Stream Ones Include:

Mobil 1 (in the crank case of every vehicle I own)(*GAS POWERED VEHICLE THAT IS!)
Royal Purple
Amsoil
REDLINE
http://www.redlineoil.com/

I have extensive experience with redline oils in my transmission and rearends in my race car and was told by one racer that I would go through two or three rear differentials a season! Running Amsoil and Redline lubes... I NEVER LOST A REAR END IN TWO SEASONS.

Redline also makes some interesting Diesel Fuel Additives, but I don't have ANY experience with them OR CUMMIN'S OPINION ON SUCH MATTERS... As for the Gear Cases ReDlInE is in my racer, my wife's truck and will be in my Rig at the 1,000 mile mark.

Ultimate choice is the cosumer's... JMHO

Happy Hunting

Mad Max, are you trying to say that LE oils aren't reputable???
LE gear oils are in almost every alcohol and top fuel funney car and dragster. Chrisman enterprises, a manufacturer of the rear ends found in these high performance cars buys and sells LE oil to the racers. Some of them buy LE oil from ME even the Quaker state man buys LE oil for use in the Quaker state funney car. Other oils tested only lasted 3 to 5 passes. LE oil lasts 40 to 50 passes. These cars run 320 mph twice as fast as yours. LE gear oil and engine oil are in all other kinds of racing as well. By the way I don't see Red Line in this kind of race car.

Mad Max (love the screen name), I have been using Red Line's, synthetic 85+, Diesel fuel conditioner (a. k. a. Diesel Fuel Catalyst. . same formula [now] as their 85+) since 3k mi. in my '98. 5 ISB. I use a maintenance dose of 1. 5 oz. to 10 gal. of fuel (per Red Line's recommendation) at each fill up. Upon removing the OE injectors at 17k mi. (when they were replaced with the Bosch RV 275 hp. injectors), it was revealed that the injectors had no buildup on them.

Oil Man, I would really like to obtain all the information you have on applicable LE products for my Ram. I have an open mind although, I will mention that I'm satisfied with Red Line's products (which I've been using for over 9 yrs. now... prior to that, NEO Synthetic Lubricants and H. P. S. [High Performance Synthetics], all very high quality products). I may however, be switching from Red Line's 15W40 All-Synthetic (14 TBN) Diesel engine oil, as it's just too expensive to use (at the rate of 11 qts. per oil change x $7. 95 per qt. without going to extended drain intervals and bypass oil filtration). Any comments?

Oil Man...

WHO? (is LE?)

Sure there is more out there... BUT LE?

Never heard anything about them until you made mention of it...

I'm certain there are more and maybe even better (there is always room for improvement somewhere?)... but the brands I've mentioned are mainstream in the circles I run in... I wasn't trying to exclude or rule out any others... just sharing my experience(s) w/ others. JMHO

Ps. Does "LE" have a http? Maybe that's part of the prob? THX

Ps. (edited) I STRONGLY DISLIKE DRAG RACING. THERE ARE TURNS IN THE ROAD OF LIFE... LEFT AND RIGHT... SAME GOES FOR RACING. =) (sorry for the poor wording earlier HEMI)

I would like to see the results of the LE 8800 Gearlube using the (ASTM D-4172B), which is the standard test for wear in the oil industry. This test is called the "Fourball" wear test.

Mad Max,
Let me try and answer some of your questions.
Fisrt, Mobil 1 was one of the first syn oils on the main stream market. I hope you are not using it in a modern diesel. Modern diesels need a more modern oil that meets current spects. Some of the oils that meet the modern spects are Amsoil, Lubrication Engineers (LE), Mobil Delvac 1, and Red Line and many more.
Second, you say "Oil Man, Who" My name is Kevin Dinwiddie I have worked for Lubrication Engineers for 21 years. I am a member of the STLE (Society of Tribologists and Lubrication Engineers) I am a Certified Lubrication Specialist #300. Look up STLE on the web and then look up member list.
Third, who is LE? They have been in business since 1951 and market in 50 countries besides the USA. They are an ISO 9001 Certified quality system. The home office is in Fort Worth, TX. , which is why it puzzles me that you haven't heard of us. Don't you live in TX???
Forth, the web page you are asking about is http://www.le-inc.com
Look it up and widen your circle of knowedge.
Sincerely, Kevin Dinwiddie (Oil Man)

(CAN'T PASS THIS UP... TEXAS IS KINDA BIG... )

Sorry Oil Man...

The Who Part was as in "WHO IS LE?"

I appreciate your throughness in addressing questions I hadn't even thought to ask. THX for the link. My original poor choice of words got this off on the wrong foot I reckon.

As for hearing of LE? (Haven't explored the link yet) are they (yall) industrial lubricants? My background is a gas engine hot rodder/racer, which may explain why I've not heard of LE until now. I appreciate the information and I will look into it.

As for Mobil one in a Diesel... I use it in the crankcase of my car because it is cheap and I change oil no more than 2,500m out... the gear cases all get Redline or Amsoil depending on the application. As for the Cummins... Well... since its not in the garage yet... I've given it only some thought... but "cheap synthetic" won't be a criterion for a $4K engine option I assure you.

Did not mean to cross ya... or "exclude yall" due to my original poor choice of words. I've yet to walk into a speed shop and see an LE Product on the shelf. But maybe that will work to my advantage... HEEE HEEE HEEEE Thx again for the 411.

Oilman, Where is a good place to buy LE lubes? Direct from plant? Live on east Coast #ad


Mad Max, I disagree with "Drag racing sucks" I have NO interest in roundy-round racing. Drag racing has:
1) MUCH higher horsepowered cars
2) MUCH faster speed
3) The fastest & Quickest classes, T/F, F/C,T/A are CHRYSLER POWERED #ad

HEMI-

Spoken like a true enthusiast that likes a different sport... .

JMHO

All racing has its own merits... just not all appeals to everyone... Sorry to Jab ya man.
(see revision above)

PS. THE HEMI IS DEFINITELY ONE OF THE BEST! Zl-1, 455 Stage III Buick, The 427SOHC & THE HEMI... The Legends... AT LEAST THE HEMI WAS PRODUCED IN QUANTITY... SHAME ON THE OTHER BIG TWO!

HEMI DART, you can get LE oils from Mag-Hytec at www.mag-hytec.com or for large quantities for commercial/industrial use you can e-mail the Oil Man at KevinDinwiddie@aol.com
Thank you for your intrest. Sincerely Kevin Dinwiddie

Oil Man,
What kind of quantities are we talking? 5 gallon pail, 55 gallon drum, and where would the point of shipping be from, Calif. or Tx? I was wondering if the prices are competitive with the other "synthetics".

Pilgram, LE has a minumin of 100lbs order. Each case (24 quarts or 3 two gallon containers) is 50 lbs. Each 6 gallon pail is also 50 lbs. We do have 55 gallon drums, 275 gallon bulk tanks, 350 gallon tanks, and 550 gallon tanks.
LE has many warehouses in the USA and will ship from the closest one.
Price of LE is slightly lower than most synthetics, and in some cases much lower.
Pilgram, I see that you are in Kauai HI. The standard freight cost is a plaine ticket to Kauai---just kidding. I believe that there is freight to Kauai we will have to talk later because I don't know how much yet. The rest of the USA there is no freight charge at all and no drum charge.
Look up my e-mail and give me more info about your needs.
Sincerely, Kevin Dinwiddie (Oil Man)
