C.I.M. Lubri Fuel

Does C.I.M Ultra Engine oil clean my engine?
All C.I.M Lubri Fuel Engine oils contain additives that improve the performance of the engine oil. These additives, amongst other important ingredients, contain detergents and dispersants. Detergents are an extremely important part of the engine oil and are incorporated into the oil blend to keep the internals of your engine clean, whilst dispersants are added to suspend the contaminants that are too fine for the filter to capture and these are then flushed away during an oil

Modern-day engine oils require carefully selected additives to perform these tasks and not become saturated during the extended oil drain interval. Late specifications such as API SN, SN+, SP and ACEA A3/B4, A5/B5 grade oils provide the highest levels of detergency to keep engines cleaner for longer. This stops the build-up of sludge; piston deposits and reduces wear significantly over their previous grades. Penrite oils are specifically developed to keep cleaning and looking after your engine for the
entire service period. To keep your engine clean, you should change your oil and oil filter regularly.

What are the benefits of Full Synthetic oils over Mineral or Semi-Synthetic?
Full synthetic base oils have a more uniform structure (meaning their molecules are near all the same size) which reduces friction and improves oil flow for better lubricity. They are less prone to oxidation (breakdown) at high temperatures which means they can provide superior protection against mineral and semi-synthetic oils during extreme operating conditions. This also gives them an extended life over mineral and semi-synthetic oils. Full synthetic oils are extremely pure, so are not as likely to be affected by impurities that may be found in some lower-grade base oils, such as phosphorus, sulphur, and wax. These impurities can impede low-temperature pumpability and increase the oxidation rates of the base oil. This makes synthetic base oils more suitable for lower-viscosity engine oils. Synthetic oils also have better heat shear stability meaning they are more likely to stay in grade over a longer period which provides long-lasting protection against viscosity loss contributing to
increased wear and oil consumption at operating temperature.

What is the difference between Heavy Duty Engine oils and Passenger Car Engine Oils?
Heavy Duty Engine oils are blended with higher concentrations of detergency and anti-wear agents
than light-duty oils. They also use different chemistry in other areas. They generally have a higher TBN (Total Base Number) due to the higher detergency and higher phosphorus and sulphated ash levels to quivalent PCMOs. Heavy-duty oils are generally designated with an industry specification that is different to light duty

oils i.e., ACEA E grade oils.
