BP IS CLAIMING a possible ti per cent improvement in consumption with its new nellus FE oil (CM February 5).
The lubricant contain unique base oil which is a duct of the hydrocrack process at the BP refinery at vera near Marseilles; hence base oil name of LHC for LaN Hydrocracker Component.
BP claims that Vanellus I produced to satisfy the criteri reasonable cost and fuel I ciency without increased we combination normally satis by a synthetic base oil.
The properties of a synth base oil include low visco low volatility and low pc point, allied to a high visco index and good oxidative st lity.
However, synthetics tend cost four times the price of c ventional refined based oil.
Because the Lavera base o refined during the BP gas oil drocracking process, it claimed that this gives I properties of a synthetic but a price people can afford," The process is covered ly world-wide patent and BP clai that it makes the final oil in pendent of the source of crudi BP has found a significar reduced wear rate on 17 1 chassis over 200,000km (125,1 miles) for each vehicle.
For 1982, BP research shovi that the operating costs (excli ing driver) for a typical 32-1 outfit were broken up as follou fuel 37, maintenance 28, dep ciation 23, tyres 11 and kik cants one per cent.
BP predicts that the new nellus FE might raise the lat figure to 1.1 or 1.2 per cent.
However, on the basis tl fleet tests have shown an i provement in fuel economy more than three per cent w Vanellus FE, then operators c look to saving between £400 £450 per year per vehicle.
These figures apply tc vehicle doing 121,000km (75,0 miles) at an average of 3' lit/100km (7.5 mpg) with changes at 9,700km (6,0 miles).
The new BP Multigear oils 80W/90 and 85w/140 can used in both gearbox and hE axle.
Being multigrades it is argu that they can replace seve grades of oil which simplif stock control.
