Royal Purple 15W-40

Personally, I don't understand the point in using synthetic oil when your oil change intervals are met. If you use a good petroleum grade oil you'll be fine. All oils have to meet certain API classification set forth by the government. Face it, there's not that many oil refineries to begin with. Can you say same oil, different label? Is synthetic better, probably. Is it worth the added expense for the same results...hmmm, nope.

If the results were the same I would tend to agree with you. However, even at the same change interval, I get cost savings with synthetics over dino due to increased MPG in my Powerstroke. YMMV. The tractor still gets the dino ~ not too concerned with MPG in it!

I just switched to royal purple 5w - 30 for my new holland. I am amased how much easier it starts in cold weather. I will run synthetic all the time. To me the added expense is worth it and it helps the enviroment to boot.

Does anyone on here have UNBIASED test results for all the oils? Which books would one get, to get the REAL facts? Does anyone have REAL WORLD results for the various oils? I hear a lot of people tell about which oil is best, but what I want is just good information. How does Royal Purple compare to Amsoil and others of that tier? What are the components of each that makes them better? What difference is there in those tier of oils and Rottella T synthetic oil? Give some real results, I could care less about assertations.

Triple T there is a magazine from OZ that did a comparison of all the Syns available. It is a real eyeopener. StreetCommadores is the name of the publication. It was last Spring they did it

I just can't help but think that there are big rigs out there w/over 1,000,000,000 mi on them by merely running good ole Shell Rotella. How much better does it get than that?

Nothing personal, but there would be the same number of big rigs running the same mileage on Walmart's "SuperTech" or whatever they call it. I bought the first Rotella ever a month or so ago to run in an old worn out Jeep because the Rotella was cheaper than "SuperTech"; Walmart's house brand. Certainly you understand that the truck companies run the absolute cheapest oil they can find that will meet their minimum specifications. Rotella's main attribute is that it's cheap not that it's good.

Is a good quality dino as good at protecting & lubricating your engine as a good synthetic? Some say yes, and some say no. Will your engine start easier in cold weather with a good synthetic compared to a good dino? No question about it, yes it will.

There are quite a few that have made a million on dino oil but I've yet to hear of one making it to a billion (nine zeroes) miles.

Welcome to the forum, btw.

The big difference is in the "wording" used. Will a dino oil do "as well" in protecting...etc..etc. The answer is NO. If the words is "will the dino oil protect the engine more than just sufficiently"...then the answer is YES!
As far as "cold weather starting" go's a "5W oil is a 5W oil"!..EITHER should allow an engine to start just as easily. ( used as an example of course)

SYN oil is the greatest thing since sliced bread...IF IT IS NEEDED...if not...then you have either wasted your $$...or else spent money on something that gives you a "warm and fuzzy feeling" and nothing more in actuality!

I have NEVER used SYN oil in ANY piece of equipment and HAVE NEVER had any sort of problem(s) with anything that might even remotely been attributed to the equipments OIL.

WITH THAT SAID...my little B3030 still has the factory 10W-30 in it...but come summer at the first scheduled change I will be going to 5W-40 Rotella SYN...BECAUSE I COULD NOT find ANY brand of oil...in the 10W-30 weight range...that is DIESEL rated that was READILY AVAILABLE to me ( execept the Kubota branded dino oil and I wasnt about to pay their price for dino oil. Do I..personally ...NEED a syn oil for MY usages...nope...but its better than usuing the WRONG oil!

Your 100% correct. Thats why in the ONLY large diesel I have..I run Chevron 15w-40 dino and NOT syn oil in it
