Fuel Economy Misconceptions: Does oil fluidity mean more consumption?

Cutting fuel costs is on every fleet manager’s top priority list. If you’ve researched cutting fuel consumption, you probably came across Fuel Economy (FE) lubricants by Total. The basic concept of Total’s FE range is to offer the same level of performance as a conventional oil, while economising on the amount of fuel used up.

Sound too good to be true? It’s not. But the hearsay around FE lubricants does mean there are a lot of misconceptions floating around. Today, we clear up the first one: Does the fluidity of the lubricants actually mean more fuel consumption?

Contrary to popular belief, the answer is no. We know that for a fact because we took FE lubricants into the lab to measure the volatility of the oils against generic lubricants. The results showed that Total’s FE lubricants formula and that of their standard equivalent are extremely close. In fact, we also found that the volatility is often lower for the W-30 grade than for the standard grades.

What’s more, our FE lubricants were also tested outside the controlled lab environment: in the real world. Our field fleet tests featured Fuel Economy engine oils (Rubia TIR 7900 FE 10W-30) and Fuel Economy transmission fluids (SAE 50 100% synthetic and 75W-90). The fleet test results showed average savings of 3.27% measured by the Engine Control Unit.

Thanks to the sophisticated formulation of the liquid and proven lab and field results, FE lubricants were subsequently awarded by the most renowned certification bodies in the world, including Millbrook. It was also approved by the most prestigious OEMs, including Volvo, Mercedes Benz, Scania, DAF, Caterpillar and many more.
