Ok, let me start by saying all of my knowledge about Diesel trucks can easily be written in pen on my palm with room to spare. My Dad is looking at getting a new truck. He probably knows less about Diesel than me. But here's the thing. He's looking to get something that he won't have to replace again. He's hoping for something that will last him until he's too old to need a truck. Anyway, I suggested maybe getting a diesel since by 100,000 km they're just starting to get broken in. The only thing is, I'm not sure if that's a good enough reason to go for a diesel? He doesn't tow a whole lot of weight (just the odd snowmobile trailer with a couple machines on it in the winter, an 18 foot all metal Grumman fishing boat in the summer and hauls the odd load of dirt or gravel). However, he does drive quite a bit. In fact within a year he had almost 40,000km put on his current truck. From 175,000 km to 210,000 km. Now, not every year is that high but I just thought that maybe a diesel would last as long as he wants. I know a gas truck can too if you treat it well and do the preventative maintenance. But he's never been one to try and learn things mechanical so the most preventative maintenance he does is check fluid levels religiously changes the oil every 5,000km or 6 months and replace coolant when the mechanic tells him it's time. Anyway, he's a bit skeptical of Diesel just because he doesn't want to fork out the money when things break and since he isn't mechanically inclined whatsoever and I know jack about Diesel engines it's all up to paying a mechanic. So anyway, just wondering what the draw backs and pluses are of getting a Diesel over Gas. He doesn't really NEED Diesel because as I said he would never use it to it's full potential power and torque wise, so it's overkill in that respect, but at least he has the power when he does need it. Thoughts?
