Need some info please on maintance

A few other points.. I have no shop and do oil changes in my driveway. It's as simple as changing the oil in a car only bigger. Put a big piece of carboard box on the ground to keep from messing up the driveway with oil/fuel and you're good to go. It doesn't look like exxon valdez oil spill in my driveway.. You can get one of those 15 gallon black plastic feed/water troughs for horses from Tractor Supply for about $20, perfect catch pan. Take an old gallon jug of oil, cut the top off, scoop the old oil out and dump it back in the 5 gallon pails, put the lid on and drop it off at auto-zone, o'riellys or whoever takes oil for recylcling.. You can also get a Chinese 1-1/2" wrench (that's what my CAT oil plug size is anyways) from Tractor Supply for about $10 - no it's not name brand but it works just fine for an oil plug. Large truck filter wrenches can be bought online or at any heavy duty parts place for practically nothing..

 

Did yall read what he said he is getting ready to buy a truck cash with 1 year experance Well I hope you have a whole lot of cash left over and when you go broke you can always get a company job and learn about the industry

 

I find errors both in your logic and in your math, although I didn't run around town to get everything before each oil change when I owned my two trucks, either. Buying in bulk has already been covered... basically, most of what I've had to say has been said - particularly by rollin coal, although I personally prefer pneumatic grease guns... I do agree that the hand actuated ones are more precise, but getting a feel for a pneumatic isn't difficult, and you can do it without blowing out seals. But, that aside, there's a couple things I want to add.
For one, it has nothing to do with being able to afford $75. There's a quote commonly attributed to Ben Franklin - a penny saved is a penny earned. So let's say you run 100,000 miles in a year, and you change your oil every 20,000 miles. So that's five oil changes with a total savings of $375. Not an impressive number in itself, I know. But here's the thing... it's a slippery slope. If you won't change your own oil, I can almost guarantee there are other menial tasks which you could do yourself, but instead will have a shop do. So it becomes $75 here, another $70 there, maybe $120 here, etc. And that adds up over time. Maybe you've anticipated your costs as far as PM goes, but there will be costs which you haven't anticipated. What happens when your AC goes tits up and you're running Texas, Louisiana, Mississippi, Georgia, Florida, and the Carolinas? You just going to roast you hindside off the whole time? I mean, whatever floats your boat, but, as for me, I'm getting it fixed. What you save by little things - doing your own PM, changing your own coolant, changing components on your own, etc. When you add it all up, it comes out to significantly more than just what you save by doing your own PM. What that does is offset the cost of the things you don't anticipate - whether it be a turbo blowing out, having to replace brakes, steering components, main bearings on the engine.. whatever it is that you're not anticipating and will encounter.
Then, you have to consider who it is that's servicing your truck. Lube tech is the low end of the totem pole. So your truck is being serviced by the least qualified tech at these chain shops. Topping that off, you're talking about someone paid by the flag hour - their pay is in accordance with the amount of time the book says it should take. So if they do a job flagged for two hours in one hour, they come out ahead. If the job flagged for two hours takes two hours, they end up on par. If the job flagged for two hours takes three, that's a blow to their paycheck. So, guess what? They're going to hurry through it, and they'll have a case of tunnel vision to where they focus only on what they're doing. Are they going to notice if your brake pads are too thin? No - you didn't pay for a DOT inspection, so why are they going to worry about it? Would they be willing to take shortcuts? It's not unheard of. Can you be assured that the drain plug at the bottom of your oil pan was torqued properly? Can you assure the filters aren't loose? Will they wash the engine compartment and underside down so that they can see where leaks, cracks, etc. might be? No.
