Car Engine oil

Looking for the correct grade of engine oil for your car ? Auto Discount Harrogate can assist you on buying the right grade of oil for your car. Stocking a wide range of oil from Technolube, Mobil 1 to Castrol Edge / Magnatec.

Technolube is a range of semi-synthetic and fully synthetic motor oils to meet the latest API and CEA requirements. Technolube also incorporates a range of low ash/low SAPS (sulphated ash, phosphorus & sulphur) fully synthetic engine oils to meet the requirements of the latest generation vehicles with exhaust after treatment devices.

Low SAPS engines can form ash on combustion, which can lead to the DPF becoming clogged up by soot, damaging the filter and impairing engine and emissions performance. So it is essential that low SAPS engine oils are used for diesel and petrol vehicles with exhaust treatment systems.The Technolube programme has the very latest specs including: 0w/20 for the Japanese petrol and diesel engines 5/w20 for the latest eco boost engines.

What is synthetic oil?

Synthetic oils are engineered to provide greater protection against engine wear and high temperatures two factors that can cause an oil to break down and be less effective. Lower viscosity synthetic oil also produces less resistance in an engine, so engines using synthetics will have more horsepower and greater fuel efficiency compared to those using a conventional oil.

Types of synthetic oil:

There are two types of synthetic oil: semi synthetic oil and fully synthetic oil. Here’s the difference.

  • Semi synthetic oil is a mix of conventional motor oils and synthetic base stocks. Think of it as a cup of half decaf and half regular coffee. Because of the added synthetic base stock, you’re going to get more performance and protection than you will by using a conventional oil alone.
  • Fully synthetic oil contains no conventional oils. Instead, they use a synthetic base stock mixed with a variety of additives that boost the performance of the oil and offer excellent engine protection. This mix of high-performance fluids and additives help prevent wear, help keep engine parts clean, flow easily, maintain viscosity, prevent rust and reduce friction.

The result is a lubricant that remains liquid and slippery under a wide range of temperatures and engine conditions. Plus, because synthetic oils also are more durable, they last longer, so you don’t have to change your oil as often.
