I wouldn't do it, there's no justification for it. Some people might think there's a benefit in added lubrication of the valve train etc, but that's unlikely as diesel fuel does have some lubrication properties anyway. You might clog up the catalytic converter if you did run it on 2-stroke fuel, and it's likely to result in more exhaust smoke.
Nissan's claims for your Pathfinder are 10.2 L/100 km average overall, and 12.4 L/100 km in urban situations. Using the latter figure as a guide your car is consuming around 30 percent more fuel than the company's claim. It must be remembered that the claim is taken from a standard lab test and not real life, and that it's meant to give a comparative figure when comparing one car to another, but to then find you car is guzzling 30 percent more fuel is unacceptable. Take it back to your dealer and demand something be done about it.
There is no scheduled maintenance on the Patrol's pump or injectors, and our Nissan experts tell us the pump and injectors are very durable. They add that they have vehicles they service that have done well over 300,000 km without any servicing on the fuel system.
Our Nissan specialist Jerry Newman says it is not unusual to find oil in the air cleaner on diesels, Nissan and other brands, but the issue really comes down to how much there. A small amount, such as a smear, is nothing to be concerned about. It would have come through the breathing system. If there's a lot of oil then it would be a problem, and you should look at the engine breathing system to find a fault. Newman says that's most unlikely on such a new car.
The claimed fuel economy for your Patrol is 11.8 L/100 km on average, which is of course just a figure provided for comparison purposes and as we have found out isn't necessarily a very accurate indicator for real life economy. One carmaker has told us that their real fuel economy number could be as much as 50 per cent out. On that basis yours would fit within the possible bandwidth of fuel economy on the Patrol. Check the exhaust to make sure there isn't a partial blockage that might be restricting the flow.
It depends on the weight you're going to tow and the terrain you'll be traveling over. Your caravan is well within the X- Trail's weight limits, but remember the weight the fully loaded weight, not just the weight of the caravan. If the caravan weighs 1300 kg fully loaded, and if the roads you will be traveling on are relatively flat then you should be able to get away without a cooler. But a cooler is good insurance against overheating the transmission, and overheating it is a good way to kill it.
The engine is tuned to run at its peak on Premium Unleaded fuel, which has an octane rating of 95. By using that fuel you will get better performance and better fuel economy, most likely better fuel economy than you would when running on the cheaper Regular unleaded. Nissan approve the use of E10 ethanol blend fuel, so that would be the best alternative fuel if you can't afford Premium.
Clutches are not generally covered by the warranty, they are considered to be a consumable component. That presumes that the wear is normal and not abnormal, but the problem with that that is that who determines what is normal wear and what is abnormal. I would consult an independent Nissan specialist and consider having a heavy - duty clutch fitted.
Have you checked your invoice to see how much oil you have been charged for? It could be a case of being overcharged for oil you don't need, or it could equally be incompetent service staff simply overfilling your engine.
