We went for a roadtrip to Batac Ilocos Norte using the Carens yesterday.
We left Pangasinan on a full tank. When we've travelled 432 kilometers on the way back, I decided to fill up. I got the ff figures:
432 kms / 27 liters = 16 kpl
I'm contented with the figures considering that the road condition was terrible as there were a lot of road constructions going on in a lot of parts of Ilocos Sur. There was a lot of stop and go traffic and one lane roads. Ang daming butas na daan and if I was to slow down, I will be left behind. I was with a convoy of vehicles (one Nissan Navarra 4x4 and a Nissan Urvan) and I kept up with the pace of the two vehicles so in effect, I subjected the Carens to a lot of stress and abuse during that trip.
I expected that I would hear some rattles and squeaks unerneath after the trip but fortunately, there was none. The Carens held up well against vehicles with tougher and stiffer suspensions.

But I wouldn't dare do that again.
I had 8 other people on board.Their only complaint - ang haba at ang layo ng trip. No complains whatsoever about the ride.
