A: The dealer and manufacturer are correct that adding some oil between oil changes in a modern engine is normal, especially considering the oil is very thin — 5w-20 weight oil — and the longer 6,000-mile oil change interval.
Additionally, while engine oil can degrade over time, typically your oil level shouldn't drop much between oil changes. If topping up your oil has become a continuous habit, you may be ignoring serious issues, such as: You aren't changing your oil according to your manufacturer's suggested maintenance schedule.
Is it normal for a car to use oil between oil changes?
In our survey of owners of about 1 million vehicles stretching back 10 years, we found that for certain models, significant numbers of consumers have to add a quart of oil to their engines as frequently as every month. It's normal for cars to burn a little oil as they age toward 100,000 miles and beyond.
Is it normal to have to top up oil between services?
While some engines may burn a small amount of oil between changes, most cars should not consume or lose a noticeable amount. Routinely adding more than a quart of oil every few thousand miles points to definite trouble.
How much oil should be consumed between oil changes?
In a tip sheet to fleet-vehicle operators, GM says normal consumption “can be in the range of one quart within 2,000 miles on a properly driven and maintained vehicle.” Other manufacturers say nothing in their owner's manuals about oil consumption — and if you ask what's “normal,” the answer you get may depend on whom ...
Check the level of the oil on the dipstick. If it reads at or below the “low” or “add” line—or if there's no oil on the dipstick at all—you'll need to add oil. If it comes out above this line in the “full” section, the oil level is fine and you don't need to add oil. Keep your car running smoothly and drive protected.
When a car mysteriously loses oil, there are usually two possible causes: either you've sprung a leak, or your engine is burning it away. Though you may not see any visible signs of leakage, less noticeable parts like a worn seal or leaky rings may be the culprit.
Engine components wear down over time. This wear can lead to small gaps between the parts, allowing oil to seep through and burn off. As a result, drivers must keep adding oil to maintain the proper level. Another reason why cars consume oil is due to oil leaks.
However, it's important to note that when changing the engine oil, both the oil filter and engine oil must be replaced together. While you can top off your engine oil if the existing filter is still good, it's not recommended to ignore an old filter and simply replace only the engine oil.
It Struggles to Start in Cold Weather. If the oil is too thick (aka, the viscosity is high), your car may not start in cold temperatures (cold weather places more strain on a vehicle in any case). ...

In general, most newer vehicles are designed to run on 6,000 or 7,500-mile cycles for oil changes (the old 3,000-mile cycle is a myth in terms of newer vehicles). Most mechanics agree that it's just a smart idea to have the filter swapped out every time you take your car in for an oil change.
Simple answer - yes no harm adding engine oil to a warm engine. Just give any oil additions time to drain down so dipstick level is accurate. Around 10 minutes is plenty.
However, engine technology has improved greatly over the years. Due to this, cars can generally go 5,000 to 7,500 miles before needing an oil change. Furthermore, if your vehicle uses synthetic oil, you can drive 10,000 or even 15,000 miles between oil changes.
You may be getting the oil level back to where it should be, but you're really just adding oil to dirty oil and ending up with dirty oil overall. And you may experience negative side effects like broken piston rings and cylinder valve head guides, an overheated or even seized engine, and more.
Note that if you do not put many miles on your car, most automakers recommend an oil change every 12 months, even if the maintenance reminder has not come on.
Check the oil level as soon as it is safe. If it is low, you'll need to top it off with fresh oil. Once you've added oil, crank the engine and see if the light goes off. If it does, get the oil changed soon and have the mechanic check for leaks that might have led to the low oil condition.
Low Oil But No Leak? You're Probably Burning Oil. Oil burning happens when faulty engine parts allow oil to seep into the combustion chamber. Blue-tinted smoke coming from your exhaust is a potential indicator of this issue but may not always be evident if your engine only burns small amounts.
If your engine is low on oil but there isn't a leak, that means it's probably being burned inside the engine. A bad PCV valve is a frequent culprit in the case of burning oil--but what is it, exactly? A PCV valve is designed to let air escape when the pressure in the crankcase is too high.
Too much oil in the engine can also cause the pressure on the crankshaft to increase, causing oil to enter the exhaust pipe from the crankshaft into the combustion chamber, blocking the combustion chamber hole with oil and eventually clogging the engine. Wet spark plug; excess oil will also flood the spark plug well.
It used to be accepted practice to perform an oil change every 3,000 miles but modern lubricants have changed that. Today, many carmakers have recommended oil change intervals of 5,000 to 7,500 miles. Also, if your car requires full-synthetic oil, it could even go as far as 15,000 miles between services.
Disposable oil filters are not designed to last for more than one oil change. Almost all disposable oil filters will get clogged before they make it to the second change. They're meant to be used only once. Reusing a disposable oil filter from the previous oil change may cause a lot of damage.
1. Get a new oil filter with every oil change. Most vehicles require an oil change every three to six months. Some manufacturers recommend replacing the filter with every other oil change, and doing so with each appointment prevents it from clogging prematurely.
Yes. If it's something you do only occasionally, mixing shouldn't damage your engine. Let's say you want to top off your oil, just to keep you rolling until your next regularly scheduled maintenance check. Mixing is alright, if the oil you use is the weight (or viscosity) recommended in your owner's manual.
