Professional grade
Lucas makes quality products and this marine grease is top notch. Its a great vale for your money because it works. I always use this grease on my water crafts and when I grease every year I notice how well it held up. So its durable professional grade.

Great Marine Grease
Excellent Marine grease, the only one I use on my outboard’s and trailer in South Florida with constant saltwater use. I always make sure to have a tube loaded in the grease gun plus this tub for any odds and ends.

Lucas Yes
You can't go wrong with Lucas products. Every product I've use has been well worth the time and $$$$. Been using this grease on my boat axles and it's holding up very well after being dunked repeatedly in the lake. Great product at a good price. I plan to order more.

The one I keep going back to for marine use
I’ve been using this marine grease for a while now, and it’s become my go-to for anything exposed to water. It goes on smoothly and stays put, even in conditions where other greases tend to wash out or break down. I’ve used alternatives before, but they didn’t hold up nearly as well over time, especially around constant moisture. This one seems to maintain its consistency and protection without needing frequent reapplication. It’s one of those products where I don’t think twice about grabbing it again. For me, it’s been a reliable choice that just works. . What you may care about: • (Meets) Holds up well around water exposure • (Meets) Stays in place after application • (Meets) Consistent texture and coverage • (Meets) Lasts longer than typical options • (Meets) Easy to apply and reuse

Useful grease for marine gear
This Lucas Oil marine grease works well for my boat's fittings and keeps everything smooth. I like that it's compact enough to carry on trips and easy to apply. Whether i'm at the dock or out on the water, it’s been reliable. Glad I picked this up since it makes maintenance quicker and helps avid issues in the long run. Definitely a handy product to have around when you’re dealing with marine equipment.

Grasa con espesante de sulfonato de calcio para aplicaciones marinas, que no obstante sirve para todo lo engrasable y que gire metal contra metal. Tiene unas características técnicas sobresalientes en todos los apartados, para lo cual se debe leer desde su pagina oficial ese apartado, cosa que no muchos hacen y es importante para poder elegir una buena opción de engrase. En mi caso soy aficionado a probar grasas en mis bicicletas y de amigos, pero cada vez voy subiendo mas el listón de la calidad, por lo que esta marca es casi obligada ya que además de esta, uso su hermana xtra heavy duty y el rendimiento es muy alto, tanto en suavidad de giro como en longevidad, aunque esta en concreto aun no le he hecho test de esto último, pero la suavidad de giro por ejemplo en bujes es sobresaliente, incluso aplicada en bujes de gama baja, o antiguos. La mayor diferencia con su hermana de color verde es que esta aguanta un poco mas de carga teórica, y su aceite es menos viscoso por lo que los mecanismos que se engrasen con ella giran mas rápido, sin embargo la xtra heavy duty de momento dura mas en óptimas condiciones, incluso con agua aunque si ese es el cometido, la grasa marina es lo mas adecuado. La imagen que muestro es de un test contra la xtra heavy duty en pedales automáticos de carretera.
