Red Line Oil's team of chemists and blenders formulate fully-synthetic oils and chemically-advanced additives using only the world's finest base stocks. This makes Red Line Oil the premium product on the shelf. It's not designed to be the cheapest – it's built to be the best. Rather than cutting cost by blending into polyalphaolefin base stock for it's motor oil, Red Line Oil only uses superior polyester-based products – resulting in lubricants that are extremely stable at high temperatures while providing superior film strength at lower viscosities where more power can be produced.
The world's top racing team and most discriminating enthusiasts use Red Line Oil products exclusively. There may be a different sponsor on the outside, but chances are it's Red Line Oil on the inside.
