Your car should never burn that much oil with the number of miles on it. My wife put on 35-40k mikes per year selling real estate and I drove 30k miles per year commuting for each of the 30 years working. I changed oil on all of our cars and never had any burn off. If you are losing a quart every 1k, you would notice.

This whole issue of burning oil has me wondering if it is being "burned"? It sounds more like a leak than anything, or perhaps it needs a ring job. Whenever my car's closed in on the 5,000 mile change period, the oil measured pretty close to full, but was very dirty. Burning a quart of oil every 1,000 miles seems excessive. I'd be concerned that there was another problem consuming the oil.

A properly functioning engine with the correct weight of oil will not burn one quart per 1000 miles. That is an absurdly high bar set by the manufacturers to reduce warranty claims. Some oil consumption is typical in "newer" cars because of attempts to improve gas mileage. For example, the piston rings are under less tension than previously to reduce internal friction and this can increase oil consumption. You haven't said which engine you have in your Ford. Some of the Ford engines have developed a reputation for increased oil consumption because of some internal failures.

Did the mechanic put in the correct weight of oil during the previous oil change? Did he put in the correct amount of oil? Assuming these are both correct and without an obvious sign of external leakage (which can typically be fixed), I suspect you have something going on internally. Since you stated you have 64K miles and don't typically like to keep cars more than 80K miles, I would be looking at replacing the car now.

As a point on the curve, I had a 2011 Honda that received only the Honda recommended 0W-20 oil (a synthetic) that I changed religiously every 5000 miles (about twice the recommended rate from the maintenance minder) and it consumed about 8 ounces of oil every 5000 miles. I sold it at 125K miles.

I doubt that my car needs a ring job, there is no smoke streaming out of the exhaust, and there is no evidence of a leak. The car runs fine. The mechanic who changed my oil was not at all surprised that a car would using that much oil. I thought that I didn't need to pay much attention to the oil level as long as I had regular oil changes and the oil light didn't come on. Apparently, this is no longer true. In the past, I have rarely added much oil to my vehicles, maybe one quart between oil changes.

That's excessive oil consumption, check your car's PCV valve for failure. Always check your cars oil after a quick start up due to all the oil from the top of the engine drains back to the oil pan overnight and will give you a false overfull reading.

Do you have a Volkswagen ?

That Ford may seem like a better value at the time of purchase but at 80K miles and you want to sell or trade it; you will see that it was not that great of a deal. You have to consider that Toyota holds its value MUCH better than the Fords.

That’s problem, most people don’t know where dips stick is till too late. My car has never used any oil between oil changes, but it’s rarely left unchanged over year with less than 5K miles. but I still check oil at least once month even though I don’t drive it that much any more. Any time I go for extended trip I check all the fluid levels and tire air pressure. No modern engine now days should be using quart of oil I 1000 miles.

If dealer told me that I would never buy that brand or take car there for service. Ford engines burn pretty clean. If car has used most oil up in 6K miles it should be evidence in tail pipe, spark plugs, and course catholic converter. When have your oil changed (NO MATTER Where you take it} should be following up on maintenance performed. When I had my oil changed at dealer they almost every time over filled it. Some times up to quart over filled cause they are too lazy to see how much oil the car actually holds and too lazy to pull the dipstick after completing oil change. Trust but verify is my motto. Another thing oil light come on when oil pressure affected that means it’s almost out of oil when pump starts pumping air.

IMO High pressure direct fuel injection washing cylinder walls. IMO HPF engines will be the new junk of the 80s. When engines was loaded down the smog junk that injected air into exhaust cheating tailpipe emissions pumping more air in exhaust.

One quart per 1000 mi in today's automobiles is unacceptable to me. Growing up in the 50's and 60's cars USED oil. By used I mean burned a little, seeped a little, leaked a little and blew some out the non existent and early PCV systems. So a quart / 100 mi might very well have been acceptable for that era. I have a '17 Lexus and a '15 F-350 diesel. I change my oil myself using the factory recommended oil weights in a synthetic oil. My car has 70k+ miles and my truck 130k+. Neither uses any oil between changes. In fact I've gotten so careless in checking that I almost never do check it. I know that might come back to bite me in the BUTT one day but that's the way it is.

That's my story and I'm sticking to it.

Friendlyvillager noted it could be PVC system, iF valve bad it can suck oil into intake and it will be burned. It should throw code

The oil light is not an indication of oil level. It is an oil PRESSURE indicator. You can have a full oil pan but without oil pressure your engine will die.

Looks like you own a hybrid. Burns gas and oil. ;)

Exactly correct. Burning 1 quart every 1000 miles is for 25 year old cars with visible smoke coming out of the tail pipe.

If the OP lost 5 quarts of oil, he has a serious problem to investigate.

Don't you ever check your oil ? Tire pressure ? Whoa.

Sounds like the mechanic got distracted. Cell call? Text?
1000 miles/quart? You'd have an oily bumper or under-bumper.

Just heard AAA no longer fixes flats. No spare? Sorry, have it towed to tire store or dealer.
Wow.
I will never buy a car with no spare. Went to a dealer recently. I said no spare, no way.
Somehow they figured-out how to put a spare and tools in car. No extra charge. Might seem that way, but
No, I'll pass on the principle of it. I might be keeping my car longer than ever; maybe forever for me.
fyi: I've had 4 flats in the past three years. One in TV, one in Bellevue, one in TN, one in VA fairly recently. None was a show-stopper; put the spare on in less than 5 minutes (TN had the flat repaired before returning home), VA filled the flat in the trunk about twice a day to make sure I got back home without a wrecker - didn't want to spend hours in a tire shop.).


btw: My ~80k car uses about 1/5 of a quart per oil change (every 5000 to 6000 miles). Never need to add oil between changes. I check the oil every few months, and tires, and before every trip of more than 100 miles.
