First item, I can see to some extent, but to say to take it down to 1 or 2 keys, I hardly think it would be necessary to take it down that far. I have had both of my vehicles for over 80k miles and not a single bit of problems. Even with prior vehicles, I never had such ignition problems. I have several keys on there that deals with both vehicles, different things for the house, 2 different work sites, and what not. As such, I do have more keys than most other people. However, I am not about to separate such keys as I’m the type that don’t want to be wasting time with having to go here for one set only to go there for another set.
While this would be important to do with older cars that still has sheet metals for their exterior walls, many current vehicles out there on the roads are made of either fiberglass or plastic, thus you don’t have that rust issue so much anymore. The main area where you will still have that rust issue are under the vehicle and anywhere near the wheels. Paint and Wax obviously aren’t going to protect those areas cause of the dirt, salt, and grime all being kicked up by the tires and what not. Yes, the frame of the vehicle is still made of steel, but that’s more or less protected by the plastic and such.
Item 3, maybe, but it’s more clutter and annoying at times than anything else. If it’s like anything else, it won’t get used properly by the kids, thus the seats will still get exposed.
Items 4 and 6, those are must do items regardless. If you don’t do those items along with proper oil changes at the proper times, then you are asking for major problems down the road. Now I haven’t had to check the levels often, but I still ckeck them no matter what when ever the oil is changed, which is only done by me. As for the tires, I do check them much more often as they are needed to be checked much more often.
Item 5, I don’t by into such things. It’s just like the various other claims used by places like the Valvoline Instant Oil changes as they claim putting in certain stuff will increase your mileage rates and charge you a higher amount for such items when they do your oil chances, but then the FTC has reported none of any such solvents really do what they claim they do. They don’t even help one bit, so such items are really a big waste of your money.
As such, the only items that you really have to do to help the vehicle last longer are items 4 and 6 along with other proper maintenance stuff as needed.
Item 1: I question
Items 2 & 3 aren’t needed as far as having the car last longer, but if you going to sell the vehicle, you would still want to do this.
Items 4 & 6 are needed among other things
Item 5, I won’t by into such gizmo solvent claims.
But then for me, I own vehicles until they won’t run anymore, which I did lose two vehicles due to their life having been essentially all used up at over 200,000 miles each, and I lost one vehicle due to it getting totaled in an accident that involved a total of 4 different semis, which my wife and kids were all very fortunate the one semi hit the back right corner of the mini van as it did else they could have all been killed or severely hurt in that wreck.
