Hybrid vehicles only occasionally use their petrol-powered engines. Without crankcase heating up, more fuel and water dilute the oil. In addition, prolonged drain intervals contribute to oil thickening and deposit formation. These heavy deposits can impede normal piston ring function; thus reducing fuel economy, lowering power output, and increasing harmful exhaust emissions and oil consumption.
Additionally, fuel dilution and acid formation can migrate from the top side of the combustion chamber and cause the engine oil to oxidize and thicken. This leads to piston ring sticking and unstable oil viscosity. Even high-quality synthetic oils will degrade eventually. Unless the oil is fortified with enhanced protection, deposits will form on many engine components.
Hybrid vehicles are typically equipped with Stop-Start technology. This means petrol is stored in a hybrid fuel system for long periods of time before it is used. When petrol sits in a fuel system for too long, it starts to oxidize.
To make matters worse, small, high output engines are extremely sensitive to deposits that build up on fuel injectors, intake ports, on intake valves and in combustion chambers. Even small amounts of deposits cause increased exhaust emissions, reduced fuel economy and drivability problems.
High operating temperatures, reduced engine cooling and prolonged drain intervals contribute to oil thickening, heat retention and deposit formation. These heavy deposits can impede normal piston ring function; thus reducing fuel economy, lowering power output, and increasing harmful exhaust emissions and oil consumption.
High operating pressures and temperatures put a lot of stress on diesel engine oils. Turbochargers, high engine idle, and direct fuel injection reduce oil life. Engine oil temperatures run high, resulting in oil breakdown and deposit formation in critical lubrication passageways. Emissions devices like EGR increase the soot accumulation in the oil. These systems place a heavy burden on the oil and push its stability to the limits.
With high combustion heat, acid formation from fuel blow-by, and soot overload, engine oils suffer from corrosive attack and abrasive wear, which eventually damage engine components.
Diesels are extremely sensitive to fuel degradation. Fuel breakdown byproducts impede injection and increase deposit buildup, leading to heavy exhaust emissions and power loss. In high-pressure common-rail (HPCR) direct injection engines, high temperatures and pressures can cause diesel fuel to break down into carbon deposits more quickly. The result is poor performance and potential engine damage.
High operating temperatures, reduced engine cooling and prolonged drain intervals contribute to oil thickening, heat retention and deposit formation. These heavy deposits can impede normal piston ring function; thus reducing fuel economy, lowering power output, and increasing harmful exhaust emissions and oil consumption.
Petrol Direct Injection engines are specifically prone to early deposit buildup on the piston surface, intake ports, injector tips and valves. As early as 32,000 km, deposits in GDI engines can cause dramatic efficiency losses and misfire codes with low km. Australian specific conditions such as heat and low-quality fuel hasten engine oil degradation. Add extended oil change intervals and these engines provide a lengthy incubation period for carbon deposits. Even high-quality synthetic oils will degrade eventually. Unless the oil is fortified with enhanced protection against high heat, premature and hard-to-remove deposits will form on many engine components.
Australian petrol fuel standard is far from world standard, resulting in faster deposit buildup and inefficient ignition, combustion and power output. Downsized, boosted engines are extremely sensitive to deposits that build up in fuel injectors, intake ports, on intake valves and in combustion chambers. Even small amounts of deposits cause increased exhaust emissions, reduced fuel economy, and drivability problems.
