About Us OLD
Road, Rally, Racing
Carlube was introduced into Tetrosyl’s portfolio in the late 1980’s and has become the largest independent oil blender in the UK. Tetrosyl has the technology to produce all the lubricant requirements from standard mineral oils right through to fully synthetic high performance racing oils.

Bringing together two of the UK’s leading oil ranges in “Carlube” and “Triple R”, we’ve simplified the search for oils across the UK and beyond. Merging the two has helped us make a sometimes complicated task more user-friendly, cutting down time spent searching around for the oil you need!
Using the same high quality additives and chemical elements as ever, our new lubricant range has not lost a drop of its quality, maintaining the way you run your engine. The only change we’ve made is a sleek re-brand, adding our new “R-TEC” numbers and colour swatch to help you find the correct oil, even easier.
UNDERSTANDING OILS
Originally, car oil was purely a mixture of base oils used to lubricate engine parts.
Today, most oils are synthetic and contain a complex blend of additives which assist in achieving a multitude of functions such as helping to prevent deposits from forming on internal engine components, removal and suspension of dirt and contaminants in the oil until these contaminants can be removed at the next oil change, enhancing engine fuel economy, lubricating moving parts and reducing engine wear.
Moving forward…
We’re constantly looking at how we can improve fuel economy for the modern car, as we know the thinner the oil, the less of a drag it puts on the engine, however, to use these low viscosity oils, the engine must be compatible, unlike vehicles of yesteryear, using an oil which is too thin would result in increased wear and premature engine failure. Engines that are now being produced will take grades such as 0W-20 and 0W-30, whereas those older engines will take grades such as 5W-40 and 10W-40.
