Can you talk about what I've always been told that grease turns into oil when it gets up to temp in wheel bearings? And then reverts to grease when it cools. If I remember things you said before that it's not true. Thanks |

TW25B is my preferred firearms grease. Unless the manufacturer recommends something specific like Lubriplate 130AA, I will use the TW25B.

Quoted: For me TW25B is by far the best grease that you can use. I have not found any other that can stand the time or heat. What do you use ? works better in my sigs, berretta, and ARs. Much less wear...and easier to clean up. |

If I remember things you said before that it's not true. Thanks It does not turn into oil. Grease’s are made up of these components: 1. Base oil 2. Your thickener/soap (lithium, calcium, aluminum, clay, etc.) 3. Your additives (vi improvers, corrosion protection, EP additives, tackifiers, etc.) 4. Dye (all grease starts out black. Just a pro tip.) The oil will bleed out of the grease with temperature changes. It doesn’t magically come back. The idea of the grease is a barrier lubricant. The oil helps carry everything. Otherwise it won’t move. I’ll take a picture of a product the oil bleed out of, and a new grease tube later if I can. But once the oil goes away the lubrication property of the grease goes down as it can’t move as easily. If you want to know more about that last part, I can go into it. But to answer your question, the oil doesn’t come back. |

I've been using Aeroshell 5 on my planes, trucks, and airport tractors sine we were buying it bulk.
I'm slowly switching over to Mystic JT-6 HT on Foxtrot08 recommendation since I don't see any good reason to spend $12/tube on grease on anything that doesn't require it. I have a Cat D6N that I got pissed off at and ran for 1K hours without greasing and I really didn't notice any abnormal wear to pins and trunions. |

Quote HistoryQuoted: ... Mower deck spindles. We’ve seen arfcom posts about this. Just peoples mower deck spindle going out... why? Well two reasons. Either you hit something and snapped it. Or the bearing ran out of lubricant. Didn’t grease enough? Well either grease more (clearly not happening) or get a better greased. ... Gotta disagree with you there. Most mower deck spindles are assembled with sealed bearings - even if they have a zerk fitting. Counter-intuitive, I know, but if you want to actually grease the bearings, you have to disassemble the spindle and use a pick to remove the grease seals installed on the inner sides of the bearings in question. Many people are greasing away on their spindles, & accomplishing ... nothing.  Your Riding Lawn Mower''s Dirty Little Secret Steve's Small Engine Saloon video explaining the spindle problem. |

Grease able.  Very grease able. Proof that you want =/= always equal reality. Lots of mower deck spindles still require grease. (Discbine actually uses a semi fluid grease. And that’s an entirely different topic. Mower deck from the 2305 does represent my point more so. ) As for greasing the actual bearing in the spindle, lots still require that. Having a bottom grease seal is a different topic. How much grease said bearing requires. Same with axle seals on tractors, etc. My point still remains the same: Why use a inferior product that costs more? |

Quote HistoryQuoted: Is there anything better out there than John Deere SD Polyurea for mower spindles and front end loader pins? I've used the SD since my compact tractor was new, but I'm open to change if there is better product for similar or less money. Short answer: No Long answer: Another shear stable polyurea grease. P66 Polyurea, Chevron SRI (arguably the father of all polyurea greases, as it came from amaco.) Mobil polytex series, citgo polyurea / mystik polyurea would all be equal. Shop your local lubricants provider. Save some money. But better quality? Not really. Not many polyurea grease manufacturers out there really. |

In climate controlled areas? Probably a year or more before you see oil bleed off. Garage in central Texas seeing 100F+ days? A lot shorter. I see oil bleed off in my garage here in North eastern Ohio. I have one grease gun set up with a needle greaser for my 2305s drive shaft U joints. I ruin tubes of grease with it. Why? Because I use a tiny amount twice a year. And it hangs in my garage that’s not climate controlled, all year. And all the oil leaks out of it. As it’s a lighter base oil full synthetic grease which, has its own issues. |

Here's a fun thread hijack:
For those of us who still lube at least some of our cast bullets with conventional bullet lubes instead of powder-coating.....how and why do lubes work? It's easy enough to say that heat and friction cause leading with unlubed bullets. what does lube accomplish on a lead bullet at 2000'? Is it really a lubricant, or is it a gas seal, or both? If you dig much into bullet lube recipes they seem like alchemy - and I suspect much of what is known isn't necessarily true. |

I just went through all this myself: what grease to use and will it work across all my vehicle applications?
Its always best to use what the spec calls out. However, when there's no spec? What brand has been around a long time, its readily available and has choices along the lubrication spectrum. I chose Mystik. JT6 hi-temp#2 for suspension, driveline, bearings, etc... JT6 multi-purpose #2 for everything else. Between researching bobstheoilguy forums, the NLGI specs amd other reaources Mystic came out on top. |

It requires reactor kettles and such, as it's much more of a chemical reaction, then just mixing. Grease is arguably good as long as it's still it's original texture. As long as it's not getting that dry/crunchy feeling to it, that means there is still oil impregnated in the soap. Once the grease dries up and it's just the soap / thickener?

It gets real fun dealing with critical applications. Certain types of greases are much harder to make (calcium complex) and it has a higher failure rate. Getting the wrong tackifier in grease. Putting grease throughout a steel mill only to have it not be able to pump... Oh industrial greases are a fucking blast. But big money. The reason why I like Mystik JT6 HT so much? It’s mystiks pride and joy. As well, they make it themselves. Most companies do not make their own greases. And the top 2 grease manufacturers in the US? Yeah they don’t have a brand. They make everyone else’s grease. Most major oil companies don’t make their own grease. My house brand grease, is a major brands grease, made by the second largest grease maker in the world. When they make this major brands grease, they make mine right after... |

Sorry, you may have answered this earlier and I didn't understand. My dad has a can of grease in his garage, with a big hole in the lid for a brush. He's had that for years and it's still got a pretty decent smooth texture to it. No idea what it is, just that it's grease. I hope the can of JT-6 I got doesn't go to shit a year from now as that will likely last me the rest of my life.  ETA: At 5-6 bucks a can it's cheap enough to replace every couple of years but frankly I don't like the idea of throwing a pound of grease into the trash, and disposing of it properly is a damn hassle.

ETA: At 5-6 bucks a can it's cheap enough to replace every couple of years but frankly I don't like the idea of throwing a pound of grease into the trash, and disposing of it properly is a damn hassle.

Old bled out of it. Dry gritty consistency. Right side - 3-4 months old. Smooth buttery consistency. So if the grease in a tube or a can/tub, and the oil can't leak out and go somewhere else, it can still be useless? Perhaps the top portion would be dry, but the bottom where the oil would pool would still be usable right, or is it a case of they separated, and stirring/mixing them now won't do any good? Sorry, you may have answered this earlier and I didn't understand. My dad has a can of grease in his garage, with a big hole in the lid for a brush.

Grease in a can / tub / pail / keg / drum / tote will separate eventually. You will see the oil puddle on top or on the very bottom depending. Tubes it’s just much more evident as the oil will literally leave the packaging. In those containers it’s more stationary. However due to what most people use it for in small containers like a can or tub, it’s not so much of a big deal as it is in a tube or something you’re going to pump. As well, since it has a lid, it will be more stable than an open tube in a grease gun, that has air / humidity / etc always affecting it. Just keep an eye on it. You know what to look for now. And yes it will typically go in layers. The outer layer will oxidation damage first. (Grease does oxidize like a motor oil does with time too. Just more stable.) |

When i use grease, it is TW25, but I've gone pretty much exclusive with SLIP.

For most of my applications, Bel Ray Waterproof. Keep a little moly for barrel nuts. G-Man VTG for trigger engagement surfaces. Some silicone for brakes and plumbing.

Real world grease test- I have a 2019 Outdoors RV 24RLS travel trailer. It is a heavy trailer with a GVWR of 9995#. I was running Valvoline wheel bearing grease and after a 60mph run down the highway wheel hub temperatures would hover in the 160 degree range on an IR thermometer.
After reading Foxtrot08's previous thread entries a while back I switched over to the Mystic JT6. Same run, same speeds and hub temps were down in the 110 range. Thank you Fox! |

RIG grease. Works well, sticky and tacky, and lasts a long time.
