Honda Civic engine Burns oil and smokes?

I have a 2008 Honda Civic LX with 280,000 miles on the vehicle. I've had a regular oil change, and serviced the vehicle accordingly. But it started burning oil and giving off burning smell. I do understand that the vehicle has lived its life. But I can't help but wonder if there's anything I can do to make the vehicle last longer without having to spend huge amount of money on engine work?

It's smoking out the exhaust? If it is constant, like a fog machine the rings are bad. If it smokes out of exhaust when it starts it's the valve seals/guides. Burning oil during combustion smells different then raw oil burning off on exh.
If it's not smoking out of the exhaust then you have an oil leak.

If the smoke is coming from the tail pipe, then to save money start looking for a low mileage used engine.

May be the previous owner did not change the oil on time? But either way 280k miles u pretty much got a lot of life out of it.

Get an engine from a junkyard.

You could try degreasing the engine. That could help with the smell. The first time I did that, it made a big difference. The smell has returned, and this time when I did it, not so much.

Make sure you check the oil level very often, at least several times a week.

Try oil for high mileage cars. It may help, but not cure wear.

Evidently your "regular oil changes" were not every 3,000 miles.Tarnish builds up on the piston rings causing them to stick in the piston grooves they ride in. Then the oil burning starts and just keeps getting worse. All you can do is change the oil and filter every 3,000 miles and check the oil every 600 miles between oil changes and never let the oil level drop more then half way between the dipstick marks.

Quick to check, fixable if it is the problem: check the breather hose and PCV hose for oil inside them. If either has oil you can clean them but replacing may be a better choice… It's up to you. If the PCV hose is oily the PCV valve has to be cleaned or replaced as well. If that doesn't turn up anything good, you can try a combustion chamber cleaner. Seafoam is popular but I'm partial to Mopar Combustion Chamber Cleaner, found at Jeep dealers. Either way follow directions but allow a long heat soak time for best results.

If you make progress (pointless if you don't) synthetic oil, or at least synthetic blend, helps prevent oil burning episodes by controlling coke buildup.

Hi no sorry it has come to needing a re-conditioned engine at least.

Check the PCV valve. They can gum up, leading to excessive crankcase pressure which in turn forces oil past the rings/bores, especially if they already have a whole bunch of miles on them. PCVs are not difficult or expensive to replace or use carb cleaner. If t's not that you probably have oil blow-by the piston or damaged valve stem seals. The only repair is gonna involve a head job. One for the car, and the other for the tech. Nasty. You could try running a thicker "high-mileage" oil, as that is less likely to squeeze through worn clearances. There are also various additives you can get for worn engines just for this purpose, but I've never tried them.
