Lucas Oil 10330 is NLGI #2 GC-LB certified and formulated to withstand high temperatures while protecting and extending the life of your engine components. This 1 lb. tub is the perfect size for a home mechanic because it contains enough lube to get the job done, and small enough to easily store. X-TRA Heavy-Duty Grease is great for any type of pressure you may put it under since it won't squeeze out like the competitors, and it's great for any sliding application.
