Motul Auto Cool Optimal Ultra is a long life antifreeze, coolant and anti-corrosion concentrate that must be diluted with soft water for immediate use as a cooling liquid, based on monoethylene glycol and using Organic Acid Technology (OAT) additives named Organic Tech. Free from nitrites, amines, phosphates, borates and silicates.


Strongly recommended for all cooling systems including passenger cars, heavy duty, commercial, construction and agriculture vehicles, gardening, marine and stationary engines.

Do not mix with non-organic products. To maintain anti-corrosion properties, do not dilute below 33%. If possible, dilute with soft water with maximum hardness 35°F and maximum chloride and sulphate content 500 ppm.

Recommended Dilutions:

SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
  • Priority shipping is also available.

How long will it take to get my order?

We give an estimate of delivery dates as you shop and in your basket. The vast majority of items are held in stock and dispatched from our UK warehouse and we'll do all we can to get your order to you as quickly as possible.
