At that age and mileage I would be more concerned with oil leaks than oil burning.
People who buy quality automobiles and take care of them, getting a good return on investment vice those who either only worry about appearances or buy crap and treat it like crap.who wants to drive a 20 year old vehicle because that’s how long it will take most people to rack up 300,000 miles.
I’ve never had a car that used oil. Took an 87 Olds to 350,000+ miles and never used oil. GM 3800 Series 1.
Same on my 5.4l. Been using oil, a little less than yours, for years but have not tried above 5w30 HM. Maybe I'll try some 5w40. My neighbor had an e350 with 5.4l since new and he always ran 20w50 because he drove to Arizona often. He was set in his ways. The internet said modular motors would explode if you tried that weight.I had a '97 F150 with a 4.6 and over 300,000 miles. It used about 1 qt every 1000 miles, and that started somewhere after 100,000 miles. On most 5-30's it was about 800-900 miles per qt, and when I switched so Castrol Syntech 5-40 it typically went about 1100 miles before it need a qt. The local oil change place did free top offs, so when they changed it, I could get three free qts added to my truck. I added over 200 qts (no leaks) to that engine and never had any oil or emissions related issues. Most of the time, oil usage is only a big deal if you're too stupid or lazy to check the oil.
I live in the Midwest where 0F is not uncommon in winter and ran that oil year 'round. Currently running Castrol Edge 0W-40 in everything in my driveway including my current 2.7 F150. I'm a big fan of 2V modular engines. Under powered but run forever. My 3V cost me an engine replacement at 120,000 miles.Same on my 5.4l.

My 2v was replaced under warranty due to the oil leaking head defect. New one now leaks too and has for 130k or so. Other than that and the stupid plastic intake/coolant crossover and snapping exhaust manifold studs it has been good.

Same here. I can not ever remember having to top of oil in any of my vehicles. None.I’ve never had a car that used oil. Took an 87 Olds to 350,000+ miles and never used oil. GM 3800 Series 1.
Yep same here. I've never owed a car that I've had to add oil to.Same here. I can not ever remember having to top of oil in any of my vehicles. None.
Use Amsoil Signature Series 100% Synthetic Oil.Hi,
It is generally considered that a car engine over time will have an increasing oil consumption. And for many cars I learned that once they pass the 300000 mi mark, a "normal" oil consumption is something like 2 gallons for every 6000 miles meaning people are driving around with oil jugs in the trunk all the time. I cannot accept that.
Is there a way to reduce the oil consumption to a minimum if the car is to pass the 300000 miles mark?
Let's assume:
I buy a car with zero miles on the clock. I want to drive it past 300000 miles. The manufacturer suggests an oil change every 6000 miles or every year depending on which comes first. In between every oil change I don't want to replenish at all. This means something like having a max oil consumption of 0,05 liter pr 1000 km ... in US i guess this is close to 2 ounces pr 600 miles. And I want this all the way up to 300000 miles in total.
What should be done to achieve this?
Special oil
Special additives
More frequent oil changes than every 6000 miles
Anything else
... or it cannot be achieved - any engine WILL wear and result in excessive oil consumption no matter how well it was treated.
Thanks, Lucas
I sure would like to see any photo of the 65 chevy chevelle. I owned (4) chevelles yet none from the 60s era. I been reading a book today all about the start of Chevelles + the special limited Z16 EPCs. I think the 64 + 65 body styles and the following 66 + 67 are awesome looking. too bad the 66 + 67 power bulge hoods were not piped for true ram air. they were just for show. all mine were from 72-76.I usually overfill by a quart then it never seems like I've got oil consumption.
In terms of car longevity, there is some frugality there. If you buy a used older car that you like for $5k instead of a brand new one for $50k, you are saving $45k. I'd rather invest that $45k in an appreciating investment like stocks than a depreciating asset like a car.I like these hypothetical questions. However, the elephant in the room is,
who wants to drive a 20 year old vehicle because that’s how long it will take most people to rack up 300,000 miles. There is a gauntlet of traffic accidents, car thieves and rust to get by, and that’s if no one steals your cat and the insurance company writes it off. If you bought the vehicle today, you would still be driving it in 2043, a time when some jurisdictions say you cannot even buy a new ICE vehicle.
