Mystik JT-8 Super HD 10w-30

[Motorbike]

This oil was of interest to me because it's available in quarts for $ 1.29 everywhere I go it seems . Even Autozone and Walmart stocks it . It has a SL/CI-4 rating and primarily group II basestock from what I can tell .

This oil seems to have a strong additive package. And it has a high viscosity index. Are you going to use this oil in a car or truck?

If you do, please publish the UOA. It would be interesting to see how this oil does.

I have heard that Citco makes the Mystic oil. My local Fleet Farm carries it in 2 gallon jugs for $8.39 for 10W30 and 15w40.

Mystic ,

The sulphated ash of this oil is going to be around 1.7 and it's not an optimal formulation for these modern gas engines , saying I'll not use it . I was hoping it would be more like the Motorcraft HD 10/30 but analysis tells different .

I am using the Mystik 5w-30 gasoline engine formula though in my Daughters 3.0 Ford and will send it in . It's a much better oil for passenger cars and is the same price . They also sell a 10w-30 in that oil .

Motorbike, I have known a few people who thought extremely highly of Mystik oil. I have known long-time mechanics and an auto racer who really liked the oil. It is kind of a strange motor oil-there are only two places locally where I know it can be found and it seems to be used by farming and ranch people a lot. I have heard that it is used in trucking also.

I have never seen a UOA on Mystik here at this web site. Even stranger, there have been very few VOAs and UOAs on Quaker State motor oils, even though Quaker State I think is the number two brand behind Pennzoil (and actually sold by the same company as Pennzoil).

Mystik oils are made in Oklahoma City by CATO Oil Company. Citgo oils are not made in the same plant. I know a 20+ year employee (grease dept.)who has always used Mystik oil and grease without any problem. He has heard rumors of sludge problems though (maybe from disgruntled employees).

Motorbike, I am using this oil in my 94 Toyota Pickup and was wondering what problems the 1.7% ash may pose?

Every once in a while I still see a case box of the Mystik with the Cato Oil and Grease Company packaging, but most cases just have the Citgo logo.

Interestingly, Mystik and Citgo still have different UPC codes - I think Mystik is 44871 and Citgo is 33159.

I have an S-10 and an Explorer running the 5/30 JT-8 premium gas, and a Jaguar running 10/30 SX-8 syn blend right now ...

Motorbike, how do you determine the sulfated ash level without a sulfated ash level being given ?

I've seen a few do it, but dunno how it's done.

Reason being my Nissan specifies high sulfated ash (for "detergency"), while specifying no better than CF-4.

It can only be guessed at although very close with a VOA and general knowledge of what some of these ashless detergent / dispersant packages look like .

Win ,

That SX-8 10-30 Blend is some very good motor oil as you probably know by now but they apparently have dropped it from the line up . At least it's not on the website now where as it was a year back .

They " Mystik " also have a 5w-40 PAO Blend with some distribution problems . Some HD stuff though . Have you ever seen it at stores locally ?

Motorbike,

The SX-8 used to be made in 10/30, 15/40, and 15/50. It looks like they are only making it in 15/40 now. I still have several cases of 10/30 and 15/50 so I'm good for a while. The SX-8 15/40 was not sold locally here, AFAIK.

I have not seen 5/40 Mystik, nor have I seen the 5/40 Citgo Syndurance, but I expect it would be a really good oil for the Jags.

Mystik is surprisingly difficult to find here given how close we are to OKC. I forgot to add I also have a Suzuki X-90 on the SX-8 10/30, and when the weather warms up, I'll probably run the Mystik 15/40 in it.

Thanks for your VOA's on this uncommon oil.

Blaine's Farm & Fleet has it here , has had it for quite a few years . I use the 10-30 in winter for my tractors , pickups and car . It is the only HD 10-30 I can find around here . I bought half dozen cases of quarts last fall , was on sale for around $1/qt . They now have , on sale , 55 gals 15-40 for $239 . Pretty good price , I'm going to get a couple barrels . I have been using Delo RPM 400 , it went up to around $320 for a 55 . I checked the specs on Mystik too , looks pretty good .

Valve trains do not like high ash levels. High ash will wear your valves out adn the seats and seals! The lower the better.

 

[Mystic]

I think the bottom line with Mystik right now is that we have no UOAs on it and few people have long experience with it. It would probably be safer at this time for somebody to use a proven motor oil like Chevron Supreme.

I do know of some people who are totally sold on Mystik motor oils, however. A mechanic at a dealership where they sell Valvoline oil told me that lots of people come in with their own Mystik oil. Mystik does have a following. But it is hard to find (where I live) and something of a mystery oil. Chevron Supreme is also a little hard to find but not like Mystik. Mystik motor oil really does merit its name-it is a mystery.

 

[Win]

The latest data sheet on the JT-8 Super Heavy Duty shows sulfated ash to be only 1.3% for 10/30 and 10/40; 1.5% for 15/40; and 1.7% for 15/50.

The mono grades are 1.6%.

Motorbike,

How did you determine this oil to be primarily group II?

Since Moly is absent from your list I assume there was none

 

[Ray H]

According to "Mystik"'s site, Citgo now holds rights to the name. The product data sheet was uploaded in October, 2003 (requires Adobe Acrobat Reader to access). The sulfated ash for the 10W-30 HD formulation is listed as 1.3, viscosity at 40oC: 81, viscosity at 100oC: 11.9, viscosity index: 143, and TBN: 11.

The Mystik MSDS for the 10W-30 HD grade lists both solvent refined heavy paraffinic (Group I) and hydrotreated heavy paraffinic (Group II) base stocks. Not indicated is whether both are present in the same batch or singly depending on supply fluctuations.

So there you have it - a free ten minute internet search has taken much of the mystery out of "Mystik".
