High Mileage trucks

I plan on going over 200k with my current truck. It is paid off. Had it since August, and have put like 20K on it. Once I graduate and start making some money, I plan on getting a V12 CL65 for cruising the highways and byways

2003 Chevrolet 3/4 ton gasser. 219k miles. I doubt I ever kill the engine. Expecting the transmission to let go around 250k.

07 GMC z71 crew cab 179,000 miles changed out brakes and u joints that's it. Hope to get 225 or so out of it.

1999 GMC Sierra 1500 SLT. 271,000 miles and still going strong on original motor and trans. Only issues I've had are a minor head gasket leak, water pump, and typical minor oil leaks. I ONLY use Mobil 1 and Lucas oil stabilizer. I would highly recommend that combination to anyone who wants to get the most of out their truck. I easily see getting 300,000+ as a daily driver. It can be done.

2005 Tundra with 176k miles. Bought it from a buddy that took care of it since he worked at a car repair place. I also have another buddy that is a mechanic at Lexus, so he can work on it if I need him to. I expect to keep this sucker for a long time. Only paid 7k for it 3 months ago.

If someone hits you who gets to decide whether the vehicle gets totaled or repaired? I have a 98 in great shape due to the fact I drive a company vehicle and spent a load of cash to refurbish the paint and interior from sun damage. i would hate for someone to hit me and I only recoup a couple thousand on my investment.

Insurance company decides. My wifes 99 escort was just totaled by someone bumping it in a driveway. Now i'm out 30k for a new Honda.

Not kidding about this: I have not changed oil in that trooper in the last 70,000 miles, I check the oil, and if it needs some, I put 20-50 in it.

I tend to default to Synthetic oil and I personally think Synthetic is more efficient for higher mileage vehicles.

I typically use 10W-30 and it just depends on whether high mileage is available. In a high mileage vehicle, i'd keep it 10W or lower and 30 or lower. You want quick oil flow at cold start up since internal components can become more worn out at higher miles. And the higher viscosity you go (30 and above), the heavier the oil, meaning the slower it will flow. Again, same premise for higher mileage vehicles in that you want better oil flow.

Synthetic oil tends to seal and lubricate gaskets better than regular oil, IMO. Better may be a lose term but I believe Synthetic extends life of the motor by decreasing leaks and offering better oil flow. Just my .02.
