As long as there has been production of internal combustion engines, there have been oils to lubricate them. Like the vehicles they are made for, oil technology has grown in leaps and bounds to get to the point we are at today. Similar to the cars we drive, the oil choices we are presented with are detailed and varied making it more imperative than ever to use the correct oil.


LIQUI-MOLY Leading the Pack

LIQUI-MOLY is at the forefront in the development of oils to suit the demands of modern day engines, with an oil available for every application in their ever growing range. Founded in 1957 in Ulm, Germany, LIQUI-MOLY have been developing oils and additives for 50 years. Their first product was an oil anti-friction additive based on Liquified Molybdenum Disulfide (MOS2) which they patented the production of. Anyone with an interest in the chemical make-up of modern oils will immediately understand the significance of this, as Molybdenum based additives are quickly becoming commonplace in hi-tech oils thanks to its ability to withstand immense loads and temperatures as well as form a protective coating on your engines internals due to its non-solubility in oil and Molybdenums natural attraction to other metals. This is also where LIQUI-MOLY got their name.

Which LIQUI-MOLY Oil is Right for my Vehicle?

When it comes to using the correct oil grade and specifications for your vehicle, always refer to your manufacturers manual, even if it’s a cheap run-around car. Using the correct oil will ensure it remains cheap everyday. Oils are graded by various ratings, with the “ACEA rating” being amongst the most common – the oil needs to meet certain performance requirements in order to receive certain ratings.


Everyday Vehicles

Oil grades and specifications can be difficult to understand comprehensively, so it is always strongly advised to stick to the manufacturers specs. Luckily the LIQUI-MOLY Super Leichtlauf and Hi-tech touring oils cater to exactly that. Available in the common grades 10w40 and 15w-40, and both meeting ACEA ratings A3/B4, they are appropriate for a majority of everyday vehicles. The Touring Hi-tech 15w40 also carries with it a heavy duty rating of ACEA E2 and meets standards set by Caterpillar, Mack and MAN.


European Vehicles

At the other end of the scale are the LIQUI-MOLY oils aimed at modern European vehicles. With exact tolerances and specific additive requirements, oil choice is critical. Two of the most common Viscosity’s of oil for your typical VW Golf or Citroen C3 is a 5w-30 or 5w-40. LIQUI-MOLY’s range of TOP-TECH 5w-30 and 5w-40 oils is second to none. The ACEA ratings are the difference amongst them with some being specifically designed for small petrol engines while others are aimed at passenger vehicles with small Turbo Diesel engines. The TOP-TECH oils are numbered differently to help you differentiate. The 4100, 4200,4400 and 4500 all meet different standards and suit different applications. These are some of the most advanced oils available today.

Performance Vehicles

For those with something a little more unusual to take care of, LIQUI-MOLY offer more specialised oils. For the competition buffs, LIQUI-MOLY 10w-60 Full Synthetic GT1 oil should be what you reach for when performance is paramount. With a viscosity rating of 60 at 100deg it offers incredible consistency under extreme temperatures and loads. A High Zinc content and LIQUI-MOLY’s own developed additives make it the oil of choice for numerous motorsport teams including teams within the Blancpain endurance series.

Classic Vehicles

If something of a higher viscosity is required for your Pride and Joy (perhaps its something historic) LIQUI-MOLY’s 20w-50 Mineral Oil comes containing their MOS2 additive that got them where they are now. The MOS2 brings with it the incredible load-bearing and anti sheer qualities it always has, giving the oil its characteristic Metallic Grey colouring. The MOS2 additive can be purchased and added to any of their engine oils at any point in the oils lifespan (though we recommend adding it when the oil is brand new).
