178947

At fifty thousand kilometres running on LPG the odometer red 178947km, still some 4k short to the break-even point.

Sometime soon the Corolla will have to pay a visit to the shop to try and sort out"the glitch" and check if everything else in the LPG system is in perfect working order.

Valve clearance will be checked next oil service at 182k.

Two years running on LPG

The Corolla got to the two year mark. 

No problems whatsoever related with valve seat recession, or of any other kind that could not be solved without fuss.

Over these two years, the 3ZZ-FE engine ran for 44595km (27710 miles) with a average consumption of 7.80l/100km (30.16mpg US 30.22mpg imperial) saving over 43 per cent on fuel expenses.

One year after

One year after getting the Corolla to run on LPG almost half of the value spent in the system installation is recovered (if it can be said like this).

The Corolla covered 24859km averaging 7.94l/100km (22.4% more than the average shown in the board computer) saving 43.5% on fuel expenses.

For every 100km the fuel expenses (LPG and petrol) are 6.56€, the equivalent of a Diesel that averaged 4.5l/100km.

The engine hasn't died, the valves haven't melted and the tank didn't blow up... still running.
