Hi all,
I'm seeking advice on my 4.5l Patrol, we have just returned from a 5 week cape York trip and I was getting 100ks to 30 litres towing a boat, before I put the exhaust system on I was getting around 22 litres per 100ks but it was gutless, now it has power but it's absolutely ridiculously thirsty, I was told it the exhaust should help fuel economy. Is there something I can do it check ??
