Q: How does Valvoline SynPower protect my engine better?

• Full synthetic oil flows more easily at start-up temperatures - when most wear occurs - and also resists breakdown at higher temperatures.

• This ability to remain stable at various operating temperatures delivers optimum lubrication and better protection at high and low temperature conditions, at which conventional oils can begin to breakdown.

Q: Can you mix Valvoline SynPower with other engine oils?

• Switching between or mixing synthetic and conventional oil does not cause problems because the oils are compatible as long as the correct specification and performance levels are matched between the oils.

• The oils are compatible with each other only if the correct specification and performance levels are matched between synthetic, mineral and semi-synthetic.

• It is very important to use the correct oil specification as stated in the owner’s manual.

Q: What’s a DPF and why would you require a full synthetic engine oil?

DPF stands for Diesel Particulate Filter. This is a filter that is fitted to diesel vehicles exhausts to meet stringent emission regulations. These capture particles created from the diesel engine combustion process. To prevent these particles from entering the atmosphere, they are captured/trapped in the DPF unit.

• During the course of driving, these particulates are burnt off in a process called “regeneration”.

• During short journeys and in stop start traffic, the filter can be subjected to higher levels of particulates. The DPF may not reach the required temperature to burn off the particulates captured/trapped in the filters, and can accumulate excessive particulates leading to poor engine performance, increased fuel consumption and sometimes expensive repairs.

Synthetic engines oils with low SAPS (Sulfated Ash, Phosphorous and Sulfur) chemistry are required for vehicles fitted with DPFs.

• Synthetic base oils are used in low SAPS engine oil products as they have the lowest impurities and with the correct additive chemistry system ensures correct DPF performance.

Q: Can you use SynPower in every car?

SynPower can be used in engines where it meets the manufacturer’s specification.

• Vehicle manufacturers mandate the specifications and requirements for their engines. Certain types of engines should not use a synthetic lubricant e.g. rotary engines, following the OEM recommendations.

• Always refer to the owner’s manual for the correct engine oil specification and follow the appropriate engine oil drain intervals as per manufacturer’s recommendation.

Q: What are the main benefits of Valvoline full synthetic engine oil?

Excellent viscosity-to-temperature properties, viscosity remains stable in low and high temperatures.

• Excellent thermal and oxidation stability.

• Low pour point, fast flow to all engine parts on start up for maximum protection.

• Protection not compromised under high stress conditions.

Q: What is dexos™?

  •  dexos™ is a proprietary, global engine oil specification designed by GM Powertrain engineers, to meet the requirements of GM vehicles.
  • Oils that meet dexos™ standards provide added performance in areas important to its operation.
  • dexos™ represents a high quality, robust oil formulated to some of the most rigorous specifications in the industry.
  • dexos™ is designed to increase fuel efficiency, extend the life of the emission system, require fewer oil changes and produce fewer emissions.

Q: What dexos™ specifications are there?

  • There are two types of dexos specifications for vehicles.
  • dexos™ 1 is for (gasoline) petrol engines.
  • dexos™2 is for diesel engines.

Q: How are dexos™ approved oils different from regular engine oils?

  • All engine oils receiving dexos™ certification are required to undergo independent oil testing with GM.
  • This includes a number of tests that are not included in current industry standards and sets performance criteria that exceeds many current standards.

Q: Can dexos™ approved engine oil be used in vehicles other than GM vehicles or vehicles requiring dexos™ approved engine oil?

  • Yes. They can be used in a wider variety of modern petrol (dexos™  1) and diesel (dexos™  2) vehicles as well as light commercial vehicles, as long as it meets other specification/s requirements as set by the engine manufacturer.
  • Valvoline engine oil with dexos™ approval is confirmation of the quality and high standard of our lubricants.
