Whatever the lift manufacturer specifies, which for car lifts is usually an HLP oil of viscosity grade 32 or 46. Here you'll find which oil goes with Weber-Werke and Wematik, plus the rules for topping up, mixing and changing. Spindle lifts don't need hydraulic oil.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eHydraulic oil\u003c\/strong\u003e is the pressure medium in hydraulic \u003ca href=\"\/collections\/hebebuehne\"\u003eCar lifts\u003c\/a\u003e: the pump in the hydraulic power unit pushes it from the reservoir into the cylinders that raise the vehicle. At the same time, it lubricates the pump and valves and protects the hydraulics against wear and corrosion. Car lifts usually run on HLP oils, mineral oils with additives against wear and corrosion.

The manual and delivery note tell you which oil the lift had from the factory. Only top up with the same specification, never a different viscosity grade on top. On a used lift with unknown contents, change the oil completely including a tank clean instead of mixing. That costs you one full fill once and saves you the question of what's actually in the tank every time something plays up later.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eIn the lift, hydraulic oil carries the pressure that raises the car\u003c\/h3\u003e\n\u003cp\u003eIn hydraulic car lifts, the oil transmits the pump's force to the cylinders, lubricates the pump and valves on the way and protects the hydraulics against wear and corrosion.\u003c\/p\u003e\n\u003cp\u003eThat applies to every lift with hydraulic cylinders: 2-post lifts with electro-hydraulic drive, \u003ca href=\"\/collections\/scherenhebebuehnen\"\u003escissor lifts\u003c\/a\u003e from short-stroke to double scissor, and hydraulic single-post models. On these, the oil is the part of the machine that carries the load from the pump to under the vehicle. If it's low or the grade is wrong, the function suffers first and, in the long run, the hydraulics themselves.\u003c\/p\u003e\n\u003cp\u003eElectromechanical spindle lifts are different. There, one motor per column lifts via spindle and load nut, and there's no hydraulic oil in the lifting system. That's how the Weber models C-2.30 and C-2.40 among the \u003ca href=\"\/collections\/2-saeulen-hebebuehnen\"\u003e2-post lifts\u003c\/a\u003e and the C-1.25 among the \u003ca href=\"\/collections\/1-saeulen-hebebuehnen\"\u003e1-post lifts\u003c\/a\u003e work. If you own one of those, you need nothing from this page; spindle and load nut are lubricated to the manufacturer's spec.\u003c\/p\u003e\n\u003cp\u003eDay to day, the oil gets noticed when something sticks: the lift rises empty but not with a car on it, one side lags, or lowering drags on. In user forums, the oil quickly gets the blame. It's one possible cause alongside valves, adjustment and air in the system. So fault-finding belongs in the operating manual, not in the next can of oil.\u003c\/p\u003e\n\u003cp\u003ePeople also search for hydraulic oil for log splitters, tractors, bike brakes and jacks. Each of those follows its own manufacturer's spec. The oils in this category are positioned for car lifts; whether one of them suits a \u003ca href=\"\/collections\/wagenheber\"\u003etrolley jack\u003c\/a\u003e is decided by its manual, not by how close they sit on the shelf.\u003c\/p\u003e\n\n\u003ch3\u003eHLP 32 or HLP 46: the number describes the viscosity\u003c\/h3\u003e\n\u003cp\u003eThe number after HLP is the viscosity grade: HLP 32 flows more easily at 40 °C, HLP 46 is thicker, and both are mineral oils with additives against wear and corrosion.\u003c\/p\u003e\n\u003cp\u003eViscosity is how thick an oil is, measured in square millimetres per second at 40 °C. Grade 32 covers 28.8 to 35.2 mm²\/s, grade 46 runs from 41.4 to 50.6 mm²\/s. Put simply: by nominal value, the 46 is a good 40 percent thicker than the 32 and flows more sluggishly through lines and valves. In practice, a lift's pump, valves and lowering speed are matched to one of these viscosities, which is why the manufacturer specifies the grade.\u003c\/p\u003e\n\u003cp\u003eHLP is the common designation for mineral-oil-based hydraulic fluid with additives against wear and corrosion. For its oil, Weber also lists water and air separation and ageing resistance. In plain terms, trapped air and moisture separate from the oil more easily, and it stays stable for longer. For you, that means less foam in the pump and an oil that ages more slowly.\u003c\/p\u003e\n\u003cp\u003eWematik writes its oil as HPL46. That's the product name; the specification on the product page is that of a grade 46 HLP oil. The grade is called HLP 46, the product Wematik HPL46, and it's the same oil. That's how manual and can match up.\u003c\/p\u003e\n\u003cp\u003eThere are also HVLP oils. Their viscosity index is improved, so their viscosity changes less with temperature. That can make sense in systems with big temperature swings. Even so, an HVLP only replaces a specified HLP oil if the lift manufacturer approves it, and we don't stock HVLP.\u003c\/p\u003e\n\n\u003ch3\u003eThe lift sets the grade, not the shelf\u003c\/h3\u003e\n\u003cp\u003eWhich oil belongs in a car lift is in the lift manufacturer's manual, and the specs differ noticeably even between brands of the same lift type.\u003c\/p\u003e\n\u003cp\u003eTwo scissor lifts, two grades: Weber-Werke specifies HLP 32 for the short-stroke scissor \u003ca href=\"\/products\/weber-werke-kurzhub-scherenhebebuehne-khb-1000e-profi-serie\"\u003eWeber-Werke Scherenhebebühne \"KHB-1000E\" Weber-Profi-Serie\u003c\/a\u003e, while scissor lift maker Kroemer specifies HLP 46 for its models. Twin Busch specifies HLP 32 for all its lifts, Wematik recommends HPL46 for its lifts. So if you buy by lift type alone, it's easy to end up with the wrong grade. The lift's brand is a quicker guide than its shape.\u003c\/p\u003e\n\u003cp\u003eIn the cold, manufacturer specs diverge. MAHA calls for a thinner oil at permanent ambient temperatures below 15 °C, Nussbaum names an ATF below 5 °C, and other manufacturers allow HLP only. So there's no general winter rule.\u003c\/p\u003e\n\u003cp\u003eIn one forum thread, an owner asks whether a 22 instead of the 32 helps against the cold; the replies advise against it and point to the setting in the manual. If your lift stands in an unheated space, ask your lift's manufacturer for approval before you deviate from the spec.\u003c\/p\u003e\n\u003cp\u003eEngine oil, gear oil and brake fluid are no substitute. They're built for other jobs, manuals for hydraulic equipment explicitly rule them out, and the wrong fluid puts the seals at risk. In forums you occasionally read that viscosity doesn't matter and engine oil will do. The manufacturer specs say the opposite, and they decide whether the lift raises and lowers the way it was signed off.\u003c\/p\u003e\n\u003cp\u003eOn mixing, the sources contradict each other: one lubricant dealer considers it harmless, another advises against it for different viscosities. Lift manufacturer MAHA only allows topping up with the same specification, and Rotary rules out mixing bio and mineral oil. The safe line follows on its own: top up with the same grade, and if in doubt, change it completely.\u003c\/p\u003e\n\n\u003ch3\u003eThe oil level is only right with the lift fully lowered\u003c\/h3\u003e\n\u003cp\u003eYou read the oil level of a hydraulic car lift at the reservoir with the lift fully lowered, because in the raised position part of the oil is sitting in the cylinders.\u003c\/p\u003e\n\u003cp\u003eThat's how lift manufacturers Nussbaum and Rotary describe it. The German statutory accident insurance recommends checking the oil level of hydraulic lifts weekly; for private use, that's a good benchmark. The daily visual check before lifting for any oil leaks is covered on the \u003ca href=\"\/collections\/hebebuehne\"\u003eCar lifts\u003c\/a\u003e page along with the other check points.\u003c\/p\u003e\n\u003cp\u003eThe change follows the manufacturer's interval. Twin Busch names a yearly change in which the tank is drained and cleaned and the oil and oil filter are replaced; Nussbaum also says yearly, Stertil-Koni about every 2 years. So the oil change belongs in the maintenance schedule, not only in the repair.\u003c\/p\u003e\n\u003cp\u003eWater in the oil, condensation for example, speeds up ageing and corrosion. Rotary gives a limit of no more than 2 percent water content. For you, that means: if the lift stands in a damp or unheated space, better not stretch the manufacturer's change interval.\u003c\/p\u003e\n\u003cp\u003eAfter filling, the hydraulics are bled according to the operating manual, in user reports by raising and lowering several times. Bleeding means driving trapped air out of lines and cylinders. Air compresses, oil hardly does. How you notice it: a lift with air in the system judders, or one side lags.\u003c\/p\u003e\n\u003cp\u003eAt first commissioning, oil quantity, limit switches and lowering speed go together: forum reports on a Weber short-stroke scissor and a Wematik scissor describe the lowering speed needing adjustment and a lowering valve being closed from the factory. If your new lift seems sluggish on day one or won't lower, that can be part of the setup and needn't be a fault.\u003c\/p\u003e\n\u003cp\u003eThe steps for checking and topping up are summed up in the instructions below this description. Repairs to valves or cylinders aren't part of that; they remain a job for customer service or a competent person following the manufacturer's spec.\u003c\/p\u003e\n\n\u003ch3\u003eWeber-Werke HLP-32 for Weber, Wematik HPL46 for Wematik\u003c\/h3\u003e\n\u003cp\u003eThe range assigns each oil to a lift family: the Weber-Werke HLP-32 to Weber lifts, the Wematik HPL46 to Wematik lifts, both with wear protection according to the product page.\u003c\/p\u003e\n\u003cp\u003eThe \u003ca href=\"\/products\/weber-werke-hydraulikoel-hpl32-weber-hebebuhnen-iso67434-hm\"\u003eWeber-Werke Hydrauliköl \"HLP-32\"\u003c\/a\u003e comes in a 10-litre container and, according to the product page, is intended for Weber lifts.
