Red Line 80312 Assembly Lube - 4 Ounce Jar

This is the best engine assembly lube money can buy: reason being that this engine assembly lube will NOT harden or thicken over long period of time. This engine lube stays put but will NOT harden and the engine bearing surfaces are protected thoroughly. Pro-tip purchase a small rubber BBQ brush and brush the assembly lube onto the surfaces you want to protect and assemble.

I recently tried this on the exterior of my AR15's Bolt Carrier and on the cam pin on the recommendation of a local buddy.OHMIGAWD is this stuff slick!It is not even an NLGI #1 thickness in my estimation and works extremely well as it is not very thick and it doesn't clump like every other grease I've used. An extremely light coating to the sides of the gas key, the 4 rails of the bolt carrier, and the bottom where the hammer rides produced an immediate and easily noticeable improvement in slickness in my well-worn LMT carrier. This improvement was seen over the likes of FireClean, which is still the slickest LIQUID lubricant I have ever used on a firearm. The carrier was well-lubed with FC prior to me removing that and applying this grease. A little goes a VERY long way and I only used a cue-tip's tip to apply it. It is also VASTLY cheaper than virtually any other "gun grease". Just superb.I'm very pleased so far and will update IF any issues arise (I doubt they will).

This stuff is really slick and goes a long way. I used it to install new cam and rockers on a new cylinder head. It stays where you put it and lasts long enough during build up. I used a brush to lube up camshaft and rockers and it stayed put while I rotated engine to adjust valve lash. I’ve used other assembly lubes, but this one surpasses them by far. The container does seem small, but it does go a long way, even when applied generously.

Love this stuff!!! Redline makes the best products out there and this lube is no exception. It's nice and thick but still thin enough to function and stay where u put it. Best part is that when mixed with the oil it doesn't clog and turns into liquid and mixes with the oil for break in or whatever the case. This stuff is absolutely amazing for building my sbc engines and I will always use this especially when building short blocks, u can put this on your main and rod journals and turn the motor by hand countless times during the build and this will stay in there and keep it lubed until start up unlike when using regular oil and other cheap lubes. It's just amazing stuff and will stay where u want it for months and months if need be. Try it out you won't be let down!!! This size of container will do me a entire sbc engine and that's with me not being stingy while using it on bearings and stuff. I know for sure if I had to make it last I could do 3 sbc short blocks with 1 of these small container's probably 4 but it goes farther then you'd think and doesn't even take much to lube something I just like to cake it on cause my motors might sit 3 or 4 months before break in or start up

This is a great "in between" grease and oil. It is super thin but stays where you put it and works waaay better in the cold compared to normal grease. If mostly hot weather is your environment, this will work. If you're consistently below freezing, motor oil or slip 2000 may work better. Use very sparingly or it will build up, catch grit! Use a qtip to only apply to rail surfaces or a small dab on gas rings.This is a quailty product for engine assembly aswell.

Horrible, it came open and in a ziplock bag with tape.

Very slippery stuff. This tub could probably be used for 5 or 6 engine builds. Easy to use in this jar. Sticks well to the part you are putting on and tools, pets, small children, light switches, etc.

Been using this assembly lube for years on all type of engines and never had any problems. Obviously just bought some more.
