A. Q8 Oils Antifreeze Long Life is for automotive, commercial vehicle and off-highway engine cooling-system service where long-life OAT G12/G12+ coolant is specified — including Volkswagen-group, MAN, Cummins, Deutz, Komatsu, Liebherr and Case engines.
A. Q8 Oils Antifreeze Long Life is supplied as a concentrate and is mixed with water at the dilution ratio specified by the engine manufacturer.
A. Q8 Oils Antifreeze Long Life is positioned within the G12/G12+ long-life coolant class — meeting both VW TL 774D (G12) and VW TL 774F (G12+) specifications.
A. An OEM Specification is the coolant requirement set by a vehicle or equipment manufacturer (e.g., MB 325.3, VW TL 774-D / G12+). When a coolant lists the code, the coolant manufacturer has developed and tested it to meet the criteria the equipment manufacturer requires. Match the code in your handbook and you have a coolant engineered for your machine.
A. An OEM Approval means the coolant has been formally tested and signed off by the equipment manufacturer and listed on their official approved-products register (e.g., MB-Approval 325.3). An Approval confirms the coolant is recognised by the equipment manufacturer for service use in their machines.
A. Q8 Oils Antifreeze Long Life carries MAN M324 e; Cummins CES 14439 and CES 14603; Deutz DQC CB-14; VW TL 774D (G12); VW TL 774F (G12+); Komatsu KES 07.892; Liebherr MD1-36-130; Case MAT 3624; and a Ford specification (verify the specific Ford reference against the current product label).
A. Both are Q8 coolant concentrates. Q8 Oils LongLife Antifreeze (this product) is the G12/G12+ OAT long-life coolant for extended-service-interval commercial vehicle and modern engine applications. Q8 Oils Antifreeze is the mainstream BS 6580 coolant — amine/phosphate/nitrite-free — for general automotive cooling-system service.
A. BS 6580 (UK) and ASTM D3306 (US) are the universal coolant performance standards every reputable coolant meets. They are your baseline check — match the standard your handbook specifies and the coolant is technically suitable for your system. Every coolant on our site lists its BS 6580 and ASTM D3306 classifications.
