When these cost savings are transferred to your average weekly transport expenses, the differences quickly add up. Consider the difference in fuel costs for my vehicles as follows:
Without Conversion:
60 litres per week of diesel fuel @ $1.40 pl
Total = $84.00 per week or
$4368.00 Annually
Compared to:
Vegiecars Quick Conversion:
Cool Climates:
60 litres per week of Diesel & Chip Oil Blend @ $0.60pl = $36.00 per week or
$1872.00 Annually - Saving 57% $2496
Warm Climates:
60 litres per week of 100% Chip Oil @ $0.25pl = $15.00 per week or
$780.00 Annually - Saving 82% $3588
Vegiecars Diesel Purge Dual Tank Conversion:
55 litres per week of Chip Oil @ $0.25 pl = $13.75 +
5 litres per week of diesel fuel @ $1.40pl = $7.00
Total = 20.75 per week or
$1079.00 Annually - Saving 75% $3289
If considering a conversion, do this break even analysis:
U = Fuel Used - litres per km
S = Fuel Cost Savings - $ per L of diesel minus $ per litre of Chip Oil
C = Cost of Conversion
R = Risk - cost of replacement of a major component such as an injector pump or alternator.
Calculate:
U x S = Savings per kilometre
C ÷ (U x S) = Conversion Break Even
(The number of kilometres your car will have to run on Chip Oil until it will have payed for the conversion)
R ÷ (U x S) = Risk Break Even
(The number of kilometres your car will have to run on Chip Oil until it will have payed for possible component failure)
Example:
My cars consumption is only 8km to the litre = 1litre / 8km
U = 0.125 litre per 1 kilometre
S = $0.80 diesel @ $1.40pl minus Chip Oil Blend @ $0.60cpl
C = $495 (Vegiecars Quick Conversion)
R = $450 (second hand alternator or injector pump replacement)
U x S = $0.10c Savings per km
C ÷ (U x S ) = $495 ÷ $0.10 = 4950kms to Conversion Break Even
R ÷ (U x S) = $450 ÷ $0.10 = 4500kms Risk Break Even
Combined Break Even = 9450km
So in less than 10,000 km I’ve not only paid for my conversion but the risk of a major component having to be replaced due to the increased pressures on old worn engine components.
