Increase Of % of Ethanol Will Cause Damage

Just wondering if anyone has used this oil for an extended period, 10,000 miles or so and seen an analysis.



I realize it is not a group iv base, but I ran the previous Rotella 5w40 CI 4+ 10k at a time and the analysis always came back good. .



I am really looking for a 3d gen 5. 9 analysis as that is what I am operating.

Hopefully I properly attached my last oil sample.



The last sample, as shown, was the Rotella T6. All previous samples were Amsoil. Notice that the longer intervals had the worse results. I was using Amsoil because of the "supposed" longer intervals between changes. As you can see, shorter intervals are better, and Rotella T6 showed just as well as the Amsoil. At a much cheaper price, and available at Wal-Mart.



Also, one of the recent TDR magazines rated oils, and Rotella rated much better than the Amsoil.



Please understand that I have been a loyal Amsoil customer for years. But the price combined with the cost of shipping have changed my priorities. Especially if Rotella T6 is just as good or better. And I get all my filters from Geno's now. Good prices and great customer service.

Mr. Trombley,

Thank you very much, that is precisely the info that I was looking for.

I run Amsoil in every other hole in the truck but am switching to the T6 for some of the same reasons.

My truck only gets one oil change a year, and I run an Amsoil bypass on it and only tow about 3,000 miles per year. So, Amsoil is just not cost effective in my truck.

My wife's Jeep liberty CRD runs about 10,000 miles per year and I was running the prior Shell 5w40 that was CI 4Plus with Blackstones and it has always come back with excellent numbers.

So, I will run the T6 in both and do an analysis on the T6 at 10K in the Jeep.

Thanks again!

P. S I do run Amsoil in my 08 FLSTC :)

But not in your engine ? :confused: Are you doing independent testing for personal comparison reasons ?


No,my truck only gets one oil change a year, and I run an Amsoil bypass on it and only tow about 3,000 miles per year. So, Amsoil is just not cost effective in my truck.

Before the changeover was made to the CJ standard, I went and bought about 3 years worth of the Rotella synthetic 5w40 CI 4 plus. I had been running that oil with analysis on the wifes Liberty and as stated above, that oil always came back OK for further service.

Flash forward to now when I only have 3 gallons of the CI 4 plus Rotella syn left and just became aware of the new Rotella T6 which of course is CJ standard not CI 4 Plus.

So, the point of my post was to find out if the new T6 Rotella syn can be run the same 10k in the Libby that it's predecessor did.

The 1 ton will still get it's oil changed once/ year as I don't currently put enough miles on it to worry about an extended drain interval.

I believe in Amsoil and run it where I can justify the cost.

On your 1 ton, why don't you just do an oil sample every year? Oil samples on a yearly basis is much less than an oil change would be. Remember, the by-pass filter element is good up to 60,000 miles with oil analysis.

Doesn't Amsoil recommend oil to be changed at least once/yr?
 
Mr. Trombley, I have never read one of these reports before. I think I understand what yours says, but I am curious about your oil change schedule. Some of your tests say 15000 miles one test and 6000 the next without a mention of an oil change. What do you use to determine when to change your oil?
 
TDaub, I used to put many more miles per year on truck and was using Amsoil to go with longer intervals between changes. But Sample results showed me that the long intervaals were not good, even with Amsoil synthetic. So I started cutting back the mileage between changes and I am now changing at about 6000 to 7500 depending on usage. Am not putting as many miles on now as I used to, so the cost of changes is not hurting so much.
 
Rotella T6

Well, I just changed the oil in the wife's Liberty CRD. It has 58. 5k on the clock and I will take a sample out at 65k and send it to Blackstone along with a TBN request.

I will update this thread when I get the data.

Thanks all for your participation in this thread.
 
Read John Martin's Technical Topics articles in TDR issues 55-58. It's all you'll need to know about oil. Valvoline Premium Blue was rated as good as any. Additives are the most important component in diesel oil. Amsoil rated average.

its been a while since ive had to think about oil samples, but if i remember correctly you look at the tbn or total base number. again if i remember right it will be listed x/y, when x gets to half of y its time to change. often what people do; and i think this is what trombley was doing is change the oil and take a sample. then determine how long you can run on the new oil based on what the anaylsis is on the old oil. ive also seen people take samples every so many miles and send them in. once wear metals get too high or the tbn drops low enough they change it.
 
The CI 4 + is the best oil why change???



as far as i know it is impossible to get ci 4+ only cj 4 is available. this is common when oils changed since all new oils must be backwards compatible with the older engines. i know there are some oils like cf and probably most all of the cx2 oils are available. (x being a variable) those oils though are rather more specialized and not copatible with all engines.

Amsoil Inc. still produces a CI-4+ oil. I'm sure there are others as well.
