High Mileage Vehicle(s) - What oil?
I have 3 vehicles that are high mileage over 100K miles. None leak oil. But, all of them burn a little over 4000 mile oil changes. I am in Florida so winter temps arent a problem. I dont want to use the high mileage oils that fix seals however, I have been considering running synthetic 10W-40 or at least something heavier in all of them. Or, should I run the 5W-30 with an additive?
What do you gurus recommend? Heavier oil or additive or both?
2006 Range Rover 5W-30 160K miles
2006 Volvo 5W-30 120K miles
2005 F150 5W-30 140K miles
No, dont even ask to sell or trade. The wifes volvo might go for a small suv but my Rover aint going nowhere, Ive had it since almost new.

Have you tried 5w30 synthetic ?
I've got some high milers as well.
2008 Jeep Grand Cherokee hemi, bought new, currently 178k miles . looks and drives like new. I've never used any fancy oils in this vehicle. Just 5w20 , and whatevers on sale. Mostly, farm and fleet house brand oil. By 3k miles, I maybe add 1/2 quart.
2004 Lincoln Town car , 145k , runs and drives like new. By 3k miles, oil level still good. Same cheapy oil.
1997 Chevy K3500 dually 454. 99k miles. This one gets synthetic 10w30. It works a little harder towing the boat and all.
Modern vehicles are much better today. I remember when if you had 100k miles they were oil burning , rod knocking , rusted out, and ready for the junkyard.

I am trying to:
-Prevent burning so much oil
-Keep them both going for another 150K

I do recall, reading on the web about the 8.1L Chevy truck engines. I saw where some guys were switching to a heavier oil, and it stopped almost all of the oil consumption.
It be worth a try. Sounds like you know your vehicles well enough to be able to determine if it helped or not. Being in a hot climate like Florida , I don't think I'd sweat the winter rating too much.

I am a big fan of the Lucas Oil Stabilizer product. I run 15-50W Mobil 1 in my 8.1L with a quart of the Lucas Syn oil stabilizer. That truck is not a daily driver so it is either pulling heavy or being stomped on because I just like to hear the bbc and the flowmaster hehe. 158k miles and runs like a Kenyan.

Used Mobil 1 gold cap 5-30 on my e430. I sold it in good running condition at 357,000 miles. Original drivetrain.
I'm a believer.
Oh, and I changed the oil when the computer told me to, and that was every 18,000-20,000 miles.
If you are using oil check you breather system. My engine had a baffle system in the valve cover that needed to be cleaned once. Oil use went away.

I have a Buick 3.8 driver/beater with just shy of 200K miles; family owned since new. I run Quaker State High Mileage with a quart of Lucas.
My 8.1L 2500HD has 99,500 miles on it, and I run the same as above. I have not owned/driven it enough to weigh in on consumption; but on a roundtrip from VA to Key West over the holidays; hauling a Harley and a small camper: it didn't drink any.
7.3L PSD F350 Dually with 130K miles: Rotella 15w40 and Lucas.
I do like the Lucas Oil products. I use it in my boat as well.

I called Amsoil and they said they never recommend running a higher viscosity than mfg recommendation. They said it actually increases heat due to more drag.
Left me shaking my head since I would assume the clearances from wear would absorb it.
