Frequently Asked Questions

When should I use assembly lube vs. regular oil?

Assembly lube is applied to critical engine surfaces before startup to protect them during the critical first moments before oil pressure builds. Use it during engine assembly or rebuild.

Will this clog my oil filter?

No — Red Line's formula is designed not to plug filters after initial engine start, unlike other assembly greases that can restrict oil flow.

What surfaces should I coat with this?

Apply to camshafts, lifters, pushrods, piston skirts, main and rod bearings, and bolt threads before engine assembly.

Can I use this on any V-twin?

Yes — it's formulated for all V-twin motorcycle engines, including Harley and Indian models.

Best assembly lube that I have not had a chance to use yet

I haven’t used it yet, but they asked me for a review a couple of days after receiving it so here it goes: the bottle is extraordinarily cylindrical!

Assembly lube

So different from my Torco and permatex assembly lubes. New lube was really thin and milky looking, didn't use!
