What is the best fluids to use

[The Beast 6.0 liter]

I have a 04 f250 and I have been using rotella oil in the engine. I was thinking about switching to royal purple oil but wasnt sure if it would be good to start switching oil brands. I just want to get the best protection in my engine and transmission as possible. I tow alot so that is also a factor. If there is another brand that would be better let me know. I also was going to switch from oem to to balwind filters. Thanks for your help

You will get many different reports and opinons on oil depending where you live. In general most use synthetic of what ever weight for the enviornment you are exposed to. They will all tell you that proper change interval is critical and with heavy towing, analysis is supported by many if not all.

I think most people use Motorcraft or Racor filters, Fuel and Oil in keeping with the OEM recommendations.

You can spend alot time on this site lurking and reading and find most of the answers to your questions. Good Luck

I have used royal purple with no complaints about the oil. I also think that it is way over priced and not worth the money. I use mobil 1 and very happy with it. This is my number 1 oil choice.

I upgraded to the new Mercon LV.

I wouldn't waste your money on Royal Purple.... EVERY test I have ever seen it was one of the worst, and way over priced.

Best is AMSOIL, Mobil 1 is almost as good....

After that, pick your poison... I will probably be using Rotella... Unless I can get a great deal on some Mobil 1 or AMSOIl.... Not holding my breath tho.

I have 100,+ on my 05 6.0 and use Amsoil. Now, i have heard nothing but good about Rotella and would use it if my buddy was not an Amsoil rep. With that said i have not heard anything bad about eiter but i have heard royal purple refered to as purple piss. No numbers to back that up though.

ever since i used up all my buckets of schaeffers 9000 i've been running 5w40 syn motorcraft. good results with both.

I've personally never run Royal Purple, but have friends that do and they haven't had any problems. I run Rotella T6 and have also not had any problems. I pay $20 a gallon at Wal Mart, they pay $25+ wherever they can find it. I'll stick with the Rotella.

Royal Purple is crap. Don't waste your money. IMO Amsoil and Schaeffer 9000 are the best out there.

Do a Google search on Royal Purple and Sludge. You won't catch me putting that stuff in any of my motors.
