DAJOLKA´s PPO cars


VW Touran 1,9TDI DPF, 105hk, 2005 Converted February 2010 at mileage 137.000km Now it has passed 4½ år and 150.000km PPO. Updated May 2014	VW Carevelle 2.5TDI DPF, 102hp, 1998 Converted February 2006 at mileage 172.000km Now it has passed nearly 8½ years and 212.000km on PPO Updated May 2014
VW Golf, 1.9 D, 1993 Converted September 1999. Now it has passed more than 10 years and 220.000km consequently on 100% PPO Updated December 2009	Citroën Xantia 1.9 TD, 1995 Converted July 2001. sold October 2006 Now it has passed more than 8 years and 228.000km on PPO Updated August 2009
All the 3 cars have been converted with a 1-tank system, enabling them to run on 100% PPO all over the year. It is still possible to run the cars on diesel or any mixture of diesel and PPO, but we prefer always to run them with 100% PPO wihout any additives. Therefore the Golf has only been fueled with PPO since 1999, and the Xantia and the Caravelle has been fueled with diesel very seldom (less than 5-10 times).

In January 2010 we bought a VW Touran 1,9TDI, installed a Diesel Particulate Filter, and converted it with a 1-tank(DI-PD) system. The Touran is replacing the Golf, which has done very well during more than 10 years. With the Touran we can demonstrate the latest technology within 1-tank systems for unit injection engines, and PPO operations with particulate filter.

VW Carevelle 2.5TDI DPF, 102hp, 1998

Converted with an ELSBETT TDI 1-tank system. The car has a 5kW comfort heater installed, supplied with diesel from a seperate tank. Pre heating the engine with the comfort heater 10-15 minuttes at winter time enables the engine to start promptly and burn efficient from the start. Alternatively to the pre heating by the comfort heater, 10-15% diesel could be mixed with the PPO in the winter season. In the spring, summer and autumn it´s not necesary to pre heat the engine with the comfort heater, or to mix PPO with diesel.

Maintenance and service:

changing lube oil and filter each 7.500km (½ interval due to direct injection engine and 1-tank system)
Adding O-ring at the return valve on the fuel filter because of problems with air in the fuel.
EGR valve cleaned in July 2006. Symptoms was reduced power and permanent smoking even at medium load.
(EGR: Exhaust Gas Recirculation, leads exhaust gas back to the air intake during medium load. The valve often fails on older engines by hanging in open position, which leads to building up of more deposits on the EGR valve, in the air intake, on the piston and piston rings, inlet and outlet valves etc. )
Diesel Particle Filter installed january 2010.

Fuel consumption:

12km/l by "fresh" driving.

Citroën Xantia 1.9 TD, 1995
(sold february 2006)

Converted with an ELSBETT IDI 1-tank system. The engine has remarkable more torque on PPO than on diesel, and therefor the fuel consumption might be a little higher on PPO than on diesel.
