Hybrid Vehicles – Engine Oil And Lubrication Requirements

Morris Lubricants Engine Oil For Hybrids

We previously posted an article citing the perils of using cheaper lubricants. In terms of engine oil and lubrication requirements, hybrid vehicles act in a slightly different manner to more conventional vehicles. A distinguishing feature of hybrid electric vehicle is that the conventional engine switches off when the power available from the electrical cell exceeds that needed to propel the vehicle. This results in lower operating temperatures and higher stress during stop/start for the conventional engine, which could lead to increased sludge and varnish than that of conventional engines.

What of service intervals?

In the UK, service intervals of 12,000 miles are usually expected by motorists. In America, some dealers are claiming that hybrid vehicles require oil changes every 5,000 miles or 10,000 miles if using a synthetic, more typical of conventional cars sold in that country. The move to lower viscosity oils could also confuse matters if a motorist has been used to using a 5W-30 engine oil in their hybrid ten years ago and today the same, but newer, model of their much-loved car requires a lower viscosity lubricant of 0W-20 or less.

For the aftermarket, although electric cars might prove a challenge today, a hybrid car is a more popular and obvious choice for motorists. They provide the assurance of extended ranges for longer journeys similar to that of conventional vehicles, with the benefit of lower emissions under town centre driving conditions.
