All aboard: How an international coach company saved fuel costs and
improved engine performance by switching lubricants
Transport Company B, a luxury, international coach company saved over
£38,000 per year in fuel costs by switching their fleet to fully synthetic Castrol
Operating throughout Britain and Europe, Transport Company B has provided
professional coach hire for over 50 years. Reliability and quality of service are a
top priority for the company and to ensure its customers travel in style and
comfort, Transport Company B invests in top-of-the-range vehicles and excellent
engineering facilities to keep them operating at peak efficiency.
With its fleet of 19 vehicles on the road for an of average 6 days a week,
covering an average annual distance of 24,188km per vehicle, the coach
company needs to be confident that its vehicles and engines are in top condition
and operating as efficiently as possible.
Lubricants typically represent a small percentage of total running costs but, as
the Transport Company B case clearly shows, choosing the right lubricant could
potentially save thousands on the annual fuel bill as well as maintenance and
repair costs. As Alan Gray, Managing Director of Transport Company B
summarised, “anything we can save a penny or two on these days has got to be
worth looking at.”
Driving performance with synthetic lubricants
Transport Company B had previously been using mineral-based oils for their
engines and basic mineral-based gear and axle oils. They worked with Race
Lubricants, now part of Certas Energy, to look at ways they could save money
on their fuel spend and select a lubricant that would work for both older and
newer vehicles in their fleet.
A key consideration was selecting a lubricant that would be suitable for not only
different ages and types of engine but also different manufacturers as Transport
Company B’s fleet included IVECO, Mercedes Benz, MAN, Cummings and Volvo
Initial trials were done with gear oils in an Allison gear box using fully synthetic
Castrol Transmax Z. Synthetic lubricants contain more highly refined base oils
than those used in conventional mineral oils, offering superior protection and
performance. Castrol Transmax Z is a high quality fully synthetic transmission
fluid that is particularly recommended for use in automatic and semi-automatic
transmissions in buses and coaches. The oil is recommended by all major
gearbox manufacturers and so was ideal for Transport Company B’s mixed fleet
of vehicles. It offers extended drain facilities and optimized frictional
characteristics which delivers smoother gear changes and protects against wear.
The resistance to oxidation prolongs the life of the lubricant which also helps to
Transport Company B had been using a mineral-based 15w/40 engine oil but
Race Lubricants converted them to Vecton Long Drain 10W/40 which is a fully
synthetic low SAPS engine oil. It’s unique System 5 Technology™ adapts to
changing engine conditions to maximise performance. The high-performance oil
is engineered to fight against harmful acids which form during engine operation
as well as preventing wear to critical engine components.
With most of the fleet now using the new Vecton 10w/40 oil, including their 1979
Bedford which has an 18 year old Cummings engine, Transport Company B
decided to change from EP 90 to fully synthetic Castrol Syntrax Longlife 75w/90
on the axles. When used in conjunction with Castrol’s synthetic engine and
driveline fluid, the entire mechanical process become more efficient, by creating
less drag and frictional characteristics. This smoother process resulted in
improved fuel efficiency and extended component life which is essential for a
busy company operating a fleet of vehicles.
Fuel and efficiency savings
By converting their engine, gearbox and rear axle lubricants to fully synthetic,
high performance Castrol products, Transport Company B was able to save 6
litres of fuel per day per vehicle which added up to a total saving of £38,058 off
their annual fuel bill a year. These savings represented excellent ROI for the
company and by using the lubricants in 90% of their fleet, the investment in a
higher quality product is now far outweighed by the benefits.
Geoff Willoughby, Workshop Manager at Transport Company B commented that
initial feedback from the drivers found that “vehicles had to be filled up with fuel
less frequently, with noticeable improvements in driving performance – gear
changes were much smoother.” These changes not only brought operational
efficiencies for the drivers, but a smoother, more enjoyable experience for
passengers. With some vehicles in the fleet operating over shorter, more local
distances (such as the school run) and some carrying out longer distances
across the UK and Europe it was easy for Transport Company B to measure fuel
savings over time.
In addition to a dramatic reduction in their annual fuel bill, their oil change
intervals have been extended from intervals of 8,000km every four months to
every 24,000km once a year, saving valuable maintenance time.
