A.P: What are your thoughts on blowing an air filter out with an air hose at the local service station – good/bad or only when needed?
Allan: You haven’t really got much choice, but if you tap it on the ground a bit get most of the dirt out and then blow it from the inside out until you can’t see any more dust – that’s all you can do and I believe it will be adequate.
Allan: Unless you want to talk about snorkels, the use of snorkels doubles the life of the motor in heavy dust conditions! If you watch a film of vehicles in convoy, the only thing protruding above the damaging dust is the snorkel head!
A.P: Wow, ok. This is a classic; leave the snorkel head on forwards or backwards?
Allan: Nah, turn it backwards ....Read more
A.P: So you should take a spare filter with you?
Allan: Yeah, I don’t like the foam ones at all.
A.P: Ok, so what about traveling with other people, say a group of 6 vehicles, good idea, bad idea, is there anything you can do to have a better trip with the air filtration?
Allan: Well either be the leader or stay half an hour behind everyone else.
A.P: Half an hour?
Allan: Well…Read more...
I’ve got a couple of questions about air filtration. Let’s say we’re going on a similar trip that you did last week, where you’re going convoy in dusty conditions; How important is air filtration?
Allan: The air filtration is probably one of the most important things to watch for. I’ve seen engines wear out in 3 months when there is bad filtration or leaks in the filtration system. I think clean air is probably the most important thing, with mining industries indicating that without proper filtration, engine life could be shortened by 50%! Read more
What role does the engine operating temperature play in excessive fuel use?
If you’re running cold, you’re getting incomplete combustion, black smoke, carbon build up. If you’re running at the right temperature, but not too hot of course, everything should be firing nicely, burning the fuel properly and running efficiently.
High speeds can also lead to excessive fuel use, why is this the case?
If you’re going at high speeds, you’ve got wide open throttle, injectors are pushing as much fuel as they can get through, and you’ve got a high wind pressure. Generally speaking, speeds over 100km will definitely soak up more fuel just from the resistance through the air alone.
