Liqui Moly vs Castrol – Which One to Go For
Let us compare Liqui Moly and Castrol and see which one is better.
The base of Liqui Moly engine oil is synthetic, mineral and hydrocracked oil. It promises maximum protection for engine components and drastically improves performance.
Castrol Group 4 engine oils (the ones used in cars like BMW) are based on a synthetic oil called polyalphaolefin (PAO).
These are synthetically created hydrocarbons made using polymerization by introducing ethylene gas. The base oil lacks lubricity, solubility, and film strength, but it is compensated using other additives.
Performance (Liqui Moly)
Liqui Moly engine oils (for example, Liqui Moly 2332 Leichtlauf High Tech Engine Oil) promise rapid oil delivery at low temperatures and high lubrication reliability at high and low temperatures.
It will drastically improve the lifetime of the car due to a high level of protection against wear and tear. Plus, it is mixable and highly compatible with all the commercially available engine oils.
It increases fuel efficiency, maintains optimal oil pressure, and keeps your engine clean. This German oil is officially certified by BMW, and you can use it during the warranty period.
Castrol is an English brand that produces a wide variety of engine oils for different types of vehicles. Their Euro Car Fluids are made using Fluid Titanium technology that transforms under pressure.

When in load, the film strength increases, which prevents any form of oil breakdown. Plus, it drastically reduces friction and has been optimized to improve the performance by 40% against ACEA standards.
Castrol engine oils are optimized to meet the stringent requirements of various European car manufacturers and comply with the ACEA oil sequences. They meet the needs of both Gasoline and Diesel-powered engines.
Since a lot of European cars come with high-performance engines that generate extreme pressure and operate at high temperatures, it can waste up to 10% of the overall engine performance by creating friction.
It generates a considerable amount of heat and can reduce oil flow. You can prevent that using Castrol Edge Titanium.
Castrol Edge 5W-40 engine oils come with Fluid titanium technology. Thus, leading engine oil dealers recommend using this engine oil for extended drain intervals up to 15,000 miles.
According to Liqui Moly’s official site, their latest synthesis and additive technology ensure that oil consumption is reduced by a lot. Based on different automobile manufacturers’ instructions, it is possible to change engine oil after 25,000 miles.
In this segment of Castrol Edge vs. Liqui Moly, the latter takes a big win.
Castrol engine oils are available in Viscosity grades 0W-20, 0W-30, 0W-40, 5W-30, and 5W-40. All of these engine oils meet the requirements of BMW Longlife 01.
Liqui Moly engine oils come in viscosity grades 5W-40 and 5W-30. But only 5W-40 Leichtlauf engine oil has approval for BMW Longlife 01.
While both these brands have engine oils with ideal viscosity grades, if you are looking for variety, Castrol takes the win.
