I am going to change my diff fluid as well as my transfer case oil. I went to Advanced auto and was going to buy MOBIL 1 but I realized that "Lucas" is 2 bucks cheaper so I decided to use it. The question is:

What does everyone think of Lucas products and do I need any special additives for the rear Diff b/c of the locker.

I am going to get 75w-90 GL-5 and use if in the transfer case and both Differentials.

Any tips would be greatly appreciated.

In my experience, Lucas makes a good product. In my jeep manual transmission, I put one quart Lucas with the factory recommended ATF and the thing was quieter and shifted smoother. If you're looking for ultimate longevity & extreme temperature protection, you can't go wrong with a good synthetic (M1). Either way, just be sure to stick with the factory recommended viscosities.

Far as i've known also as Scott said Lucas makes a great product i run their 2 stroke oil in my CR 125 and it hasn't seemed to slow down any over the last 7 or 8 months...and my friends that race dirt track and haul gravel believe in their products also...so my opinion is that go with them they're a high performance product which should keep your vehicle in good shape for a while.

From my experience pretty much all of those good names: Mobil 1, Lucas, Amsoil, Redline, etc. are going to be quality products. I am currently running Amsoil in the front and rear diffs and Redline in the Tranny and Transfer Case. Seems to be a good match for my Manual tranny. IMO

Also, if you want to run Amsoil I know a ton of members are dealers including a couple from my home state, WA. They could probably hook you up with what you need.

Good product. I use Valvoline syn in my transfer cases and have been real happy with it. Mike

If I run Lucas will I need to add anything to the rear diff b/c of the locker

No just run the proper viscosity and you will not need to run any special LSD additive.

I remember that there was a thread about the Lucas oil stabilizer. It did not sound very good for Lucas then. Check this link: http://www.bobistheoilguy.com/images/lucas/lucas.htm

Lucus

I personally do not like any additives in oil other than an LSD additive on certain carriers. I have found certain additives cause oil to collect or collect by themselves in certain areas of the motor. I have used Lucus in my big block Cummins for some time as an oil additive and I feel it is just to thick to run through certain areas even when heated and can cause more problems than you want. I now use no additives in crank oil in my Kenworth or Taco or transmission of my Tacoma. With all the fine synthetics on the market there should be no reason for oil additives. Run spec weight, choose your oil, follow service intervals or shorten them for severe running. Just my opinion but this is how I handle my heavy & light equipment.

I haven't bought any of this(yet) but his prices are good and I am starting to prefer the smaller guys to the giants.
