My Random Thoughts on Keeping a Car Running for a while

Feel free (as I know you all will!) to agree or disagree. Nothing magical here. Just felt like listing the things I learned to do over 61 years of doing (or having it done) car maintenance.

1. Keep oil changes to no more than 5000 miles, particularly on newer turbo GDI engines. IMHO, trying to go 10-20,000 miles is a good way to shorten the life of the engine, create sludge, cause timing chain issues, etc. Check your oil level regularly!

2. I always put in a new oil filter with each oil change. Force of habit.

3. On annual basis, I try to do three or four one quart replacements of coolant. Since hot coolant flows through my overflow tank, I do it there. But you could also do it by siphoning off an inch or so in the radiator and replacing it. My plastic overflow tanks are spotless right now in the cars in my signature and the coolant looks like new. Should help the water pump as well. BTW, I always use distilled water to dilute full strength antifreeze.

4. Check tightness of screws and fasteners under the hood every time you change the oil. Hose clamps loosen and I even had a bolt that snugged the exhaust to the turbo loosen. Cheap insurance to do this.

5. Keep the car, particularly underneath, washed off in the winter after driving on salty roads. Use an oily anti-rust coating (many have been discussed on here). Catalytic converter guards can rust off, frames can literally disintegrate. etc.

6. Keep an eye on rubber parts such as door gaskets, bellows on steering and suspension components and cooling hoses. Remember, typical rubber in these applications is swellable by petroleum products!! If you must apply a lubricant, stick with silicone oil or grease. And keep in mind that even sprayable silicones in a can may have a petroleum carrier! Test those sprays on a styrofoam cup before using.

7. Apply a UV absorbing cleaner/protector (non-slippery type) to interior surfaces so that they don't crack and fade over the years.

8. Keep the interior clean! Get rid of the sandwich wrappers, drink cups, etc. Don't smoke in your car. Actually, don't smoke at all!!!

9. Keep good weatherproof mats on the floor of your vehicle. This is also a good idea in cargo areas.

10. Keep your tires inflated to proper pressures and DON'T ignore the spare tire (if you are lucky enough to have one!) Make sure that the car has a good alignment to prevent tire and suspension wear.

11. Have any leaks into the interior found and repaired before the floor rots out under the carpet!

12. Change fluids on a regular and sensible basis. Transmission, differential, transfer cases, Torsen setups, etc. all need maintenance. Use the correct fluids at the correct viscosity. This is also true for so-called "lifetime" fluids!! If you want to keep the vehicle, change 'em out!

13. Keep an eye out for chips in the paint. I use the little paint repair bottles or tubes. Fix it before rust starts!

14. Make sure that the engine air filter and the cabin air filters are changed on a reasonable basis. I think 20,000 miles is a good time to change the cabin filter.

15. I am a believer in flushing out the brake fluid and replacing it every three years or so. This keeps moisture in the system to a minimum.

16. Replace suspension parts as needed. Trying to keep driving with bad parts in the suspension just leads to more issues and more money spent.

17. If possible, replace parts with OEM or very trusted parts from another manufacturer. Don't cheap out on parts that require a lot of labor to install or that might put your life in danger (ie cheapo brake parts). This particularly applies to tires!!

18. DO sit down when you buy a car and READ the owner's manual!

19. Use quality fuel. To me, it is crazy to spend $50,000 on a car and then run something like Sheetz 87 octane in it. I use Top Tier fuels.

20. Keep the car clean on the outside. Maintain it with car washes and if possible the occasional wax job. Remove tree sap, bugs, etc ASAP.

21. If at all possible, keep your vehicle garaged or in shade during the day. UV light can go after paint, interior fabrics and plastics and the rubber in your tires.

If anyone has any other thoughts to add, I would be pleased to see them.
 
We have 3 family cars over 150K (98 F150, 04 Escape, 14 Armada) and one over 100K (09 Mazda5). Bought all of them new, did some spirited "ring seating" on all of them on the drive home from the dealership to the house and changed the oil/filter as soon as it cooled down a little, changed again at 500 miles and then went to 5K OCIs on them. None have had any driveline issues, I change transfer case/tranny/diff oils at 30K intervals and do complete antifreeze changes every 5 years.

I do skimp on brake fluid service, its just a PITA to do, I need to be better in that arena.
 
My current assumption is that a quality car will be reliable for at least 300k if maintained as the OP suggests. Beyond that stuff will fail at an accelerating rate from age as much as use. Plus the vehicle at that point is worth less than the cost of a major repair.
20 years ago my assumption was 200k miles. At my age (73 this week) I won't be making any assumptions 20 years hence.
 
I do about eight or nine of those things. I change oil at 10,000 miles. Sometimes I don't change the oil filter. I change the coolant per the manual. About every 50,000 to 100,000 miles.
 
Good tips. Don’t follow oil change OCI or fuel.

I use 10k interval per VW and at 190k no issues.

I worked on off brand gas station in college. We bought ends of tanker trucks including premium sometimes added to our regular tanks from branded stuff like Mobil , Shell , BP etc. All trucks went to same depot in Boston but each brand had a tank or so.
 
My only differences: 10k mile/1 year OCI, brake fluid every two years, and running Top Tier fuel exclusively.
 
IMO, easily the most important factor in your list is checking the oil level and ensuring it does not go low. Low oil levels probably accounts for a significant amount of early engine wear and failure, and no, the light on the dashboard is not there to tell you to add more.

Some cars do have an oil level warning light.
