A. Valvoline Multi-Vehicle Antifreeze Coolant is for cooling-system service across the full range of vehicle manufacturers — particularly useful for topping-up or refilling vehicles of unknown service history where the existing coolant chemistry is not known.
A. Valvoline Multi-Vehicle is positioned as a universal-compatibility coolant using the Alugard Plus additive system. Where possible, the cooling system should still be drained and flushed before refilling — mixing coolant chemistries can degrade performance, and the safest practice is to use the coolant type specified by the engine manufacturer.
A. Alugard Plus is the Valvoline compatibility additive system used in the Multi-Vehicle range — designed to perform across the major coolant chemistries (IAT, HOAT, OAT) and protect aluminium cooling-system components across mixed-fleet service.
A. Valvoline Multi-Vehicle Antifreeze Coolant is supplied as a concentrate and is mixed with water at the dilution ratio specified by the engine manufacturer.
A. Valvoline Multi-Vehicle Antifreeze Coolant meets ASTM D3306; ASTM D4985; ASTM D2809; SAE J1034; SAE J1941; and SAE J814.
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.
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.
