Emissions force shorter oil drain

• Dr Paolo Volpi, director of Fiat Lubrificanti, has warned that oil drain periods may have to be reduced as emission limiLs are tightened and affect engine design.
The prediction came as the company announced that the latest development on its Urania Turbo LD oil will cut the particulate emission of engines in which it is used.
The company says that about a quarter of particulate produced in an engine comes from the lubricating oil. This is halved with the new oil, says the company.
However, as the top land on pistons is reduced to minimise the dead area within the combustion chamber, the temperature the oil has to withstand increases dramatically, he says. -We expect an increase of between 50-100°C. This will decrease the longevity of oil."
Urania Turbo LD is said to have a specification well in excess of CCMC 1)5, API CE, DB 228.3, Volvo VDS and MAN QC 13-017. It is said to be suitable for extended drain periods in other makes of engine.
Price is said to be competitive even against oils of a lower specification from other producers. How ever, it is currently only available via lveco Ford dealers.
0 Using Urania Turbo LD, lveco Ford ha-s set service intervals on the 7.5 tonne New Cargo at 40,000km for the six-cylinder engine and 30,0001cm for the four. For any other oil the service intervals drop to 30,000km and 20,000km. The longer drain periods help lveco Fords' claim that routine servicing costs 40% less for New Cargo against its competitors. It has published a brochure which it says justifies this claim.
The figure is made up of parts prices claimed to be 11.5% lower than "any top-selling 7.5 tonne'', and extended service intervals.
