1) Does the Mystik® JT-6® Hi-Temp Multi-Purpose Grease contain moly?
No, there is no molybdenum disulfide in Mystik JT-6 Hi-Temp Multi-Purpose Grease. The new Mystik JT-6 Hi-Temp with 3% Moly Grease is a great choice if your equipment operates in severe-duty conditions.

2) Can the Mystik® JT-6® Multi-Purpose Grease be used to grease bearings in boat trailers and utility trailers? How about automobile wheel bearings?
Mystik Jt-6 Multi-Purpose grease is a medium temperature range multi-purpose grease for extreme pressure loads and slow to medium speed bearings. It is excellent for grease chassis points, fifth wheels, and water pumps. It works especially well where extended lubrication intervals are practical, highly loaded or shock loaded grease lubricated applications exist, and excellent rust protection is desired. It is fully rust and oxidation inhibited.

3) 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 Mystik® 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.

4) I use my boat in saltwater as well as in fresh water lakes. Will the Mystik® JT-6® High Performance Marine Grease protect my boat trailer wheel bearings when exposed to corrosive saltwater environment?
Yes, the new corrosion resistant additive technology formulated into the Mystik JT-6 High Performance Marine Grease is highly resilient in battling the effects of salt water corrosion. Most marine grade greases will do an adequate job in protecting bearing surfaces from rusting when trailer bearings are exposed to fresh water, however, it takes a premium product like JT-6 High Performance Marine Grease to maintain a protective water fighting coating around the bearings and combat the pitting associated with saltwater corrosion.

5) I really like how Mystik® JT-6® High Performance Marine Grease protects the bearings in my trailer from rust, corrosion, and wear but I would like to know if I can use this grease in other applications other than just trailer bearings.
The Mystik JT-6 High Performance Marine Grease offers excellent heavy and shock load protection along with being highly water resistant. This combination of performance qualities enables this grease to be used in many applications: winch gears, hydraulic jack plates, boat dock machinery, pivot points on outboard and inboard engines, boat steering mechanisms, automotive chassis, fifth wheel, king pins, steering knuckles, bucket pins and ball joints just to name a few of the applications this versatile grease can be used in.

6) How often should I regrease my boat trailer bearings?
This depends on several factors which can include: the amount of use, the load you are carrying, wheel size, and driving conditions i.e. hot dusty, dirty roads. At minimum grease should be added to the bearings at least twice per season and more often if pressurized grease fittings “bearing buddies” are not used in the wheel hubs and frequent trips to the lake are encountered.

7) I am not sure what grease I am currently using. The only thing I know is it is red in color. Will Mystik® JT-6® High Performance Marine Grease be compatible with this red grease?
The color of the grease offers little clue as to the thickener type, performance, heat range, or water resistance of grease you are using. Mixing various greases is never considered normal and always offers a risk of incompatibility. As a safe practice, when in doubt about compatibility, the old grease should be purged or wiped cleaned from the bearing and race before the new grease is applied.

8) Is Mystik® JT-6® High Performance Marine Grease compatible with lithium base grease?
Yes, Mystik JT-6 High Performance Marine Grease has shown very good compatibility with lithium, lithium complex and calcium based greases.

9) Where can I purchase Mystik® JT-6® High Performance Marine Grease?
You may purchase from one of our local distributors. There is a locator here on www.MystikLubes.com. Click on the “Where to Buy” tab and enter your “Postal Code.” The closest source point will be provided.

Hydraulic Fluids

1) What is the weight of Mystik JT-9 LeakShield® AW Hydraulic Fluid 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 JT-9 LeakShield® AW Hydraulic Fluids are formulated with a very effective anti-foam agent designed to prevent foaming.
