Hydraulic Oil Booster/STO

This product is amazing! It instantly improved my hydraulic system’s performance, reducing noise and leaks. The oil booster enhances smooth operation, and the stop-leak feature works wonders. Easy to use—just pour it in! Great value for the price. Highly recommended for anyone dealing with hydraulic issues. Lucas Oil never disappoints—definitely a must-have!

I have a 743 old bobcat skid steer that was leaking really bad. I took it in twice to fix the leaks down in the bottom under the cab. They said I needed to replace the control valve and function valve block and instead I use this product and it stopped the leaks within an hour of running!

I added this to my tractor’s hydraulic system, and it made a noticeable difference. The small leak I had is now completely gone, and everything runs smoother. Great product that actually works as promised. Will definitely keep a gallon on hand for future maintenance.

Pretty much like ALL Lucas products I have used, this Lucas Hydraulic Oil Booster does exactly what it claims to do. I used this product in the sump of my I/H Farmall 340 tractor with hopes of stopping (or at least slowing down) a leak in the hydraulic cylinder on the draw bar, and within 10 minutes of use, the leak completely stopped. What's more, all of the hydraulics seemed to work much better, and held pressure like they are supposed to do. I used a ratio of one gallon Lucus to 10 gallons of Hytran oil. I probably could have used less? In any event, I found this to be a great product, and well worth every penny! Saves money, saves time, and a lot of hard labor as well!

Bueno para sellar

Quality product

Stops leaks, boosts performance—essential for hydraulic systems!

I can't speak to the longevity of this product as I only used as a stop-gap until I could get a ram resealed; however it plugged a nasty leak on the tipping ram of my 32tonne tipper lorry, and after about six repeated tip/lower operations leak stopped completely. I only bought it as a "well it can't hurt to try" option but was very pleasantly surprised.

Have not seen any improvement with my wet clutch jumping to neutral but I have a few leaks in my loader fittings so it has helped that problem

pour une fuite d'environ une goutte toute les 45 a 60 secondes ça n'a pas marcher le vendeur m'a dit que la fuite était trop importante ......je pense que c'est un produit efficace contre l'évaporation peut être mais pas pour les fuites...(.j'aurais aimer avoir une autre explication pour environ 70 euros le bidon )
