1. Mobil 1 High Mileage 10W-40: Best Overall for Oil Burners
In our evaluation, Mobil 1 High Mileage 10W-40 stands out as the top choice for cars that burn oil. This full synthetic oil combines a robust additive package with seal conditioners that help rejuvenate aged gaskets and reduce oil seepage. Based on owner feedback and the spec sheets, many drivers report a significant drop in oil consumption after switching to this oil. Its 10W-40 viscosity provides a thicker film at operating temperature, which can help fill worn clearances and slow oil loss. The oil also meets the latest API SP and ILSAC GF-6 standards, ensuring compatibility with modern engines.
One real weakness is its cold-weather performance. The 10W rating means it thickens more than a 5W or 0W oil in very low temperatures, potentially making cold starts harder. If you live in a region where winter temperatures regularly drop below -20°F, you might consider a 5W-40 high-mileage oil instead. Also, this oil is priced at a premium compared to conventional blends, but the reduction in oil top-ups can offset the cost over time.
- High-mileage formula with seal conditioners to reduce leaks and oil consumption
- Excellent thermal and oxidation stability for extended drain intervals
- Meets or exceeds ILSAC GF-6 and API SP standards
Pros: Noticeably reduced oil consumption in many owner reports; Strong engine protection even under high heat

Based on owner feedback, some users reported a moderate reduction in oil consumption, though results varied. The oil also helps keep engines clean by resisting deposit formation.
However, its high price is a major drawback. For the cost, many other high-mileage oils offer similar or better reduction in oil burning. Additionally, some owners found that it didn’t reduce oil consumption as effectively as thicker oils like 10W-40 or 20W-50. If your engine burns oil only mildly and you prioritize performance, this could be a good fit. But if your main goal is to minimize oil loss, you might get better results from a more affordable thicker oil.

Frequently Asked Questions
What type of oil is best for cars that burn oil?
High-mileage oils are specifically formulated with seal conditioners and additives that help reduce oil consumption. Thicker viscosities like 10W-40 or 20W-50 can also help fill worn clearances. We recommend starting with a high-mileage oil in the viscosity recommended by your owner’s manual, then moving to a thicker grade if oil consumption persists.
Can thicker oil stop my car from burning oil?
Thicker oil can reduce oil consumption by better sealing worn piston rings and cylinder walls. However, it may not solve the root cause, such as worn valve guides or seals. It can also reduce fuel economy and cause cold-start issues. Always check your owner’s manual for the maximum viscosity allowed.
Is synthetic oil better for cars that burn oil?
Synthetic oils generally offer better thermal stability and longer drain intervals, but they may not always reduce oil consumption more than conventional high-mileage oils. Some synthetic blends can actually be thinner at high temperatures. We recommend high-mileage formulations, whether synthetic or conventional, as they contain additives to condition seals and reduce oil loss.
How often should I change oil in a car that burns oil?
If your car burns oil, you should check the oil level frequently and top off as needed. Follow the manufacturer’s recommended oil change interval, but consider shorter intervals if you are using conventional oil or if oil consumption is high. Synthetic oils can often go longer between changes, but monitor oil level and condition regularly.
Can oil additives help reduce oil burning?
Some oil additives, like Lucas Oil Stabilizer, can thicken oil and reduce consumption temporarily. However, they are not a permanent fix and may cause issues if used excessively. We recommend using a high-mileage oil with built-in additives rather than adding aftermarket products, as they are formulated to work safely with the oil’s base stock.
