I have been searching on here & haven't found a ton of grease related arguments....I mean discussions. I know how these generally go but I figured for the sake of the search function we could discuss grease & who likes what why.

I like Mystic JT-6 mp grease for everything except the wheel bearings, for that I have always used the Mystic high temperature grease. Today I went to Tractor supply to re-up my grease supply & to buy a new mini-gun for the under truck work & noticed a new (new to me) grease called "Green Grease"; it's said to be synthetic,waterproof,chemical proof,compatible with other greases & good for temperature ranges from -20F to 500F. I'm thinking of trying it out on some wheel bearings up front on my 4Runner when I change out my rotors in the coming days; does anyone have any pro's or cons with this grease vs. my reliable old Mystic?

And as I said earlier, feel free to discuss any other grease you like, don't consider it a topic derail as long as we keep it about grease & the components of & uses for grease.

 

Any grease > no grease at all.

Synthetic grease is a bit more expensive, but generally worth it, in terms of moisture rejection and protection.

I use "Super Lube" it's got a corny name, but is NLGI rated, and full synthetic. I use it on everything except birfields and CV's. Everything from window frames in the house to rollerblade bearings, bicycles, and wheel bearings, etc.

Cheers.

 

LOL...yeah I guess it does, technically speaking. The "Green Grease" I mentioned earlier is an NLGI #2 grade which is the same as the Mystic high temperature red grease I usually use. The Mystic is labeled as disc brake wheel bearing grease whereas the "Green Grease" pretty much says it's good for everything

 

SOOoooo, no one has an opinion or loads of facts about greasing our beasts so a newbie can find a good discussion with the search function? Well then, I'll just have to throw more of my opinions in here.

#1 as we all know some vehicles have sealed grease boots on front ends & even some U-joints & over pumping the grease can blow them out so we have to be armed with the knowledge of what types of grease points we have & how much grease comes out per pump on the gun.

#2 if you travel in water often, crossing creeks,large puddles, rivers etc. you need a waterproof grease! It's not an absolute of course, but imagine this scenario - You drive from your home in your DD/trail rig to 4x with some friends; it's a long way there and all your bearings are hot from a 200 mile drive. The first thing you see when you pull off the road is a 300 ft. long puddle a foot deep from a recent rain on the road in. All your buddies are on the other side saying "hurry up & air down; we've been waiting on you!"

You do it & get on the trail only to find it's water-water everywhere. You're in a hurry when your done for the day & it's getting late; you have to be at work the next day & you don't have a grease gun with you; there's another 200 miles on your bearings & this time they're washed out! If you are smart you carry grease with you, but not all of us are smart.

Then you might ask, what grease should I use? Well, most people will say "any multi-purpose moly grease". But that isn't appropriate for wheel bearings in disc brake vehicles where the temps can get searing hot; it's ok for chassis lube, U-joints & cv joints though.

If you play in the mud & water a lot you might look into a marine grade grease. The bush pilots in Alaska need a wheel bearing grease that can stand up to high shearing forces, salt & fresh water! Ask them if grease is grease & they'll give you an ear full. The trouble with marine grade grease is that not many of them say they will work for disc brake wheel bearings, they say "boat trailer wheel bearings" in 99% of the ones I've looked at. But by the same token most of them are NLGI rated.

If you go on a grease related forum you'll find they discuss (argue) the points about soap based grease, mixing different grease,synthetic grease separation while sitting for long periods,emulsification factors etc. Bob is the oil guy.com & Noria.com are two good places to look for extensive & detailed discussions, but they aren't Toyota specific, as well as heavy equipment sites, aircraft sites,racing sites (I wonder what the road race guys like NASCAR run in their cars??) Good places to get grease are of course, auto parts stores but also Wal-Mart type discount stores & places like Tractor Supply & farm & ranch outfits.

Come on guys, lets add to Yota-Techs knowledge base.

Edited for spelling

 

i would have an opinion--but i cant find a decent air powered grease gun that works--can we talk about that also?

 

But as a side note--think the Lucas might be a contender

 

I just picked up a tub of Mobil 1 grease at AutoZone the other day for $6. I figure it will last me a while.

grease, dang I have to get a grease gun soon, I need three.

A little off topic, how do you clean out a grease gun, I have a few around, but have no clue whats inside.

 

I'd use diesel fuel myself...or WD-40.

hross14; As far as talking about grease guns, sure why not...it's grease related.

rdlsz24; have you ver had the synthetic separate on you while sitting in the tube? I have heard the synthetics will do that; I've never used a synthetic myself.

 

I just bought two new grease guns alongwith a tube of moly and a tube of lithium. Is it generaly moly "under" the truck and lithium in the front wheel bearings? Subscribing! good thread!

p.s. I read up on 4x4 wire and all the YT posts but was still left confused. I followed the pictures on 4x4 wire the best I could and that got me through it but it would be nicer to know for sure next time instead of pulling up more pictures.

 

You might check out bobistheoilguy.com & noria.com for more detailed discussions on grease & oil if you still have questions that can't be answered here.

Most greases are lithium based or soap based from what I gather & the different soap bases are why you're not supposed to mix different greases; (I'm no grease guru). What I do know is Moly grease is excellent for all applications where the temperatures are going to stay fairly low. The grease for wheel bearings on disc brake applications where more heat is generated needs to withstand at least 350F if I'm not mistaken. The "Green Grease" I mentioned before that I picked up at Tractor Supply is supposed to be rated to 500F & is chemical resistant & waterproof, it was unnecessarily expensive at $9 per 14oz tube so it better be grrRREAT lol.

I'm going to build new rotors for the front of my '95 4Runner in the next few days (weeks maybe...wifes darned Isuzu Trooper is eating my funds) & I plan to use the new "Green Grease" in that work for the spindle & the wheel bearings. Then when I get a few miles on it I'll check it out & see how well it was retained, check for metal content, bearing wear etc. I've always had great service from the Mystic high temp. red grease but I'm always willing to give something else a try.

Oh hross14; I noticed quite a few people like the lucas brand, that & Schaeffers, Mobil 1 & Mystic seem to be the top greases used in automotive applications.

 

Grease is grease, oil is oil and trans fluid is trans fluid. People buy into all this hype of which is the best one to use, then wonder why it costs them 50 bucks a tub for grease, or a quart of oil, etc.

Buy what makes you happy, my shop just uses valvoline high temp wheel bearing grease for almost everything and no issues yet.

 

This is my first try with synthetic grease. I know in the past even with normal grease in my grease gun sometimes it gets watery and leaks out of the gun making a nasty mess.

Though I don't agree 100% with that part; I get the gist of what you're saying. I'm not specifically talking about "What brand is better than what other brand" or what additives do you like (the age old snake oil argument). More along the lines of what type is used for what application like you stated in the last part of your post; or more to the point what type does each individual use & why & how has it worked for you over time vs. others you've tried. It also matters what you use it for, some people swear the Mystic grease is very prone to wash out. That is why I'm going to try the waterproof high temperature grease. I've not had much issue with wash out but after I play in the mud & water I grease my wheel bearings & don't rely on the grease to hold up.

I suppose the high temp. red Mystic would do it's job about as well in the chassis as it does in the wheel bearings unless there is some need for higher heat indexes to properly distribute the grease where it needs to be that I don't know about.

 

Not true, new Synth oil doesn't meet the testing standards that good old Dino oil does.
