I would stay away from Royal Purple. Amsoil is okay, Mobil products are also a good choice.

They will not back their products like Mobil and Amsoil will. If you have an oil related problem which does happen now and then, I always recommend someone that has the proven technology and the ability to stand behind what they sell. Royal Purple has creative marketing and some loyal customers so thay can't be all bad.

Friend of mine runs Lucas diesel oil at this moment, tested the oil at Blackstone and it was in bad shape by 8K in a newer Cummins. They recommended replacing it by 9K, which he had already passed in the time frame of a week. He drives a 03 and now hates the Lucas oil, not the additive, but the oil itself.
He has had great luck with the additive in his long haul trucks, but the Lucas has come back used up by 9K three samples in a row. Be sure you pick your oil well, it is the blood of your truck.
I personally use Amsoil because I used it and heard the differance it made not only in the noise level of my truck, but also because of good results of testing by Blackstone (who is not affiliated with Amsoil at all). The chioce is ultimately in your court and everyone on this site has opinions, so take half of what you read with a grain of salt.

I have been doing some reading about Schaeffers, and I found their synthetic oil is based of a parrifin base. Knowing what I do about #2 and the waxes and parafins in that fuel, I dont want that in my engine. Bio-diesel breaks down the parifins in a fuel system depositing them into the filter, what is going to keep that same parafin from clogging the oil system? After years of use, something has to get clogged up same as the fuel system.
If I am wrong in thinking this way, then someone please chime in with something scientific to disprove my thought.

Why don't you go right to the horses mouth and ask Schaeffer your concern?I know lots of fellow excavators who like me run Schaeffer and they have a few million miles on their fleet.Their engines are clean as a whistle.And if you're running bio, why are'nt you concerned about your fuel filter clogging?

You're right about parafins. They are bad. Even Penzoil Long Haul 15/40 is high in parafins. That's why you don't see many trucking co's using Penzoil. The real nuts and bolts are based on the facts such as cSt, Viscosity index, Sulfated Ash (Biggie with 07 emmission engines), TBN (total base number) , and pour point. The next big items after that are the additive packages. Some companies have extremely good marketing and get people to beleive in their products whole heartedly and the oil is not as good as they beleive, but the fact is that it's in there and providing some lubrication. The good oil companies primarily name brands are better that most fancy named one's and I won't pick on them this time around but they're all over this post. Mobil/Exxon by far is the better option all the way from basic fleet oil to Delvac 1. Shell Rotella T is okay, but the synthetic version is not good and mismarketed. Amsoil is hanging in there, but technically doesn't impress me or anyone else who knows oils and looks at new oil compared to it's lifespan and ability to perfrom certain functions.
Pick oil for what it really is. Some oil needs to be changed more frequently purely because the additives drop out of suspension or have been depleted of their necessary characteristics. We all can go on all day about which one is best and most of the time they hooked you on pure marketing propaganda. Go to the websites and print out Technical Data Sheets and compare. Then run an anaylsis and see whick characteristics are failing first and choose from there.

Shell Rotella T 15/40 dino is great oil. The Rotella Syn is not a good synthetic option though. The Rotella Syn is made from Class III Base Stocks and not a true Class IV PAO synthetic as it shouod be

x2 for Schaeffers. Take the time to educate yourselves and go to Schaffers web site. If you download their product info you will find that they include all test results for each of their fluids. No other oil company divulges more information. I wonder why??? Use what you want, just don't believe the hype about Amsoil. All their base stock comes from Exxon/Mobil so you might as well buy Delvac 1 and save yourself some money... JMHO

The transfer case uses ATF, so you can use TranSynd or any other good ATF fluid. The front and rear diffs. can use oem GM grape juice, Mobil 1, Lucas Syn., Royal Purple, Valvoline Synthetic, and Schaeffers, and probably a couple more I haven't mentioned...avc8130;1556593; said:

That has worked with tractor trailers in many different tests. They tried all combinations of synthetic and mineral oil. If you put synthetics in everything suck as transmission, differentials, power steering any anywhere else there's fluid there is about a 1/12 - 2mpg increase. The synthetic crankcase oil had minimal if no influence on the results.[email protected];1563979; said:
To properly test you will need two identical test vehicles. Two round trips and switching drivers in between.
