1) Is the new Mystik JT-8^® Synthetic Blend Super Heavy Duty Engine Oil compatible with the previous non-synthetic JT-8?

Yes, the new synthetic blend and previous formula are very compatible. However, to experience the full benefits of the new JT-8 Synthetic Blend, filling the crankcase with the new formula is required.

2) I have always heard that synthetic oil causes your seals to leak. Will I start to see oil loss with Mystik JT-8 Synthetic Blend Super Heavy Engine Oil?

That is not true. It would be foolish for Mystik or any other oil company to formulate a lubricant that would cause damage to the seals. If your engine is leaking from old, cracked or hardened seal material the JT-8 will not heal or worsen the problem.

3) I would like to use Mystik JT-8 in my truck but am unable to locate your product at fuel service sites. Why?

The Mystik product line has historically been sold through farm and ranch type retail outlets. In addition, many auto parts stores now carry Mystik branded products.

4) Does Mystik JT-8 Synthetic Blend Super Heavy Duty Engine Oil meet the new API category CJ-4?

No, the Mystik JT-8 engine oils 15W-40 and 15W-50 are API CI-4 PLUS rated. The new Mystik JT-8 EMT (Emissions Management Technology) is API CJ-4.

5) Can I add Mystik JT-7^® Multi-Purpose Gear Lubricant to a "positive trac" or “limited slip" type differential?

Yes, the Mystik JT-7 gear lubricant can be used for make up and drain and refill for this type of differential.

6) Does the partial synthetic Mystik SX-7^® Gear Lubricant have the proper additives for use with limited slip axles?

Yes!

7) What is the viscosity of the Mystik JT-5™ Universal Trans-Hydraulic Fluid?

The viscosity of the Mystik JT-5 is similar to a SAE 10W-30.

8) Will the Mystik JT-5 Universal Trans-Hydraulic Fluid meet the John Deere J20C specification and the Ford M2C134 C/D?

Yes, JT-5 is an excellent choice for applications calling for these OEM specifications.

9) Does the Mystik JT-6^® Hi-Temp Multi-Purpose Grease contain moly?

No, there is no molybdenum disulfide in JT-6 Hi-Temp Multi-Purpose grease. New JT-6 Hi-Temp with 3% Moly grease is a great choice if your equipment operates in severe-duty conditions.

10) Can the Mystik JT-6^® Multi-Purpose Grease be used to grease bearings in boat trailers and utility trailers? How about automobile wheel bearings?

Yes, Mystik JT-6 Multi-Purpose grease can be used for trailer bearings and other non disk brake bearing applications. For automobile disc brake wheel bearings, the Mystik JT-6 Hi-Temp -- which is rated NLGI GC-LB – is required.

11) Does the Mystik Power Lubricants^® Tenax^® Fluid SAE 10W meet the Caterpillar TO-4 specification and does it contain 900 ppm zinc which is required by CAT?

Yes, Mystik Power Lubricants Tenax 10W, 30W, and 50W are formulated to meet the performance requirements of Caterpillar TO-4. All three Tenax viscosity grades are formulated to exceed the minimum 900 ppm zinc requirement for CAT equipment.

12) Can the Mystik Tetrimoly^® Extreme Duty Grease be used for off-road equipment such as dozers and backhoes? Does it contain moly and what is "moly"?

Yes, Mystik Tetrimoly – now called JT-6 Hi-Temp with 3% Moly -- is an excellent choice for use in off-road mining and construction equipment. The word "moly" is short for molybdenum disulfide which is a chemical compound used in many lubricants to minimize metal-to-metal contact by adhering to the metal surface and reducing friction. Moly is not a permanent film and must be replenished by regreasing.

13) What is the weight of Mystik Power Lubricants^® AW Hydraulic Oil ISO 32, 46, 68 and 100? Do these oils contain detergent? Will they foam?

The approximate SAE viscosity grade for an ISO 32 hydraulic oil would be a 10 weight, the ISO 46 and 68 are grouped as SAE 20 weights and the ISO 100 is a 30 weight. These oils are non-detergent and will readily separate from water. The Mystik Power Lubricants AW Hydraulic Oils are formulated with a very effective anti-foam agent designed to prevent foaming.
