Q 1. What engines is Q8 Oils Formula Special D1 5W-30 designed for?

A. Q8 Oils Formula Special D1 5W-30 is designed for the latest GM engines requiring the Dexos1 Gen2 specification. It is also suitable for passenger cars and commercial vehicles with normally aspirated or turbo-charged gasoline engines.

Q 2. Is Q8 Oils Formula Special D1 5W-30 approved for GM Dexos1 Gen2?

A. Yes, Q8 Oils Formula Special D1 5W-30 is developed for the latest GM engines requiring Dexos1 Gen2 specifications.

Q 3. Is Q8 Oils Formula Special D1 5W-30 backwards compatible with GM-LL-A-025?

A. Yes, Q8 Oils Formula Special D1 5W-30 is backwards compatible with GM Opel engines requiring GM Dexos 1 and GM-LL-A-025 engine oil specifications.

Q 4. What is an API/ACEA classification?

A. API and ACEA are the universal lubricant performance standards every reputable oil meets. They are your baseline check — match the code your handbook specifies (e.g., API CI-4 or ACEA E7 for heavy-duty diesel) and the oil is technically suitable for your machine. Every oil on our site lists its API and ACEA classifications.

Q 5. What performance classifications does Q8 Oils Formula Special D1 5W-30 meet?

A. Q8 Oils Formula Special D1 5W-30 meets API SN and SP.

Q 6. Does Q8 Oils Formula Special D1 5W-30 protect against LSPI?

Q 7. What is the difference between Q8 Oils Formula Special D1 5W-30 and Special D1 FE 0W-20?

A. Both are GM Dexos1 Gen2 passenger car engine oils. The 5W-30 (this product) is the standard-viscosity Dexos1 Gen2 oil. The 0W-20 (PRD00002972) is the fuel-economy low-viscosity Dexos1 Gen2 oil delivering higher fuel saving. Select per the GM vehicle manufacturer's required viscosity.

Q 8. What is an OEM Specification?

A. An OEM Specification is the lubricant requirement set by a vehicle or equipment manufacturer (e.g., MB 228.3, VW 504.00). When an oil lists the code, the oil manufacturer has developed and tested it to meet the criteria the equipment manufacturer requires. Match the code in your handbook and you have a lubricant engineered for your machine.

Q 9. What is an OEM Approval?

A. An OEM Approval means the oil has been formally tested and signed off by the equipment manufacturer and listed on their official approved-products register (e.g., MB-Approval 228.3). An Approval confirms the oil is recognised by the equipment manufacturer for service use in their machines.
