Noticing blue smoke from your exhaust? Constantly topping up engine oil? If your vehicle burning oil, it’s a red flag you can’t ignore. At Best Cash For Cars Melbourne, we’ve seen countless cars with engine oil burning issues – a problem that drains wallets and risks engine seizure. This guide covers every angle of burning oil in a car, from diagnosing why your car burns oil quickly to your most cost-effective solution.
Is Motor Oil Flammable? (The Science Behind the Smoke)
Let’s address a critical question: is engine oil flammable? Absolutely. While less volatile than petrol, motor oil ignites at 300-400°C – temperatures easily reached in combustion chambers. When internal engine seals fail, oil slips into cylinders and burns, creating:
- Blue-tinted exhaust smoke
- That acrid burning oil smell
- Rapid oil level drops
- Potential oil signal car dashboard warnings
Is car oil flammable under normal conditions? No. But in faulty engines? Yes. That’s why car burning engine oil demands immediate attention.

“Burned by Oil – What Do I Do?” Your Action Plan
If you’ve confirmed burning oil in a car, take these steps:
Check Levels Weekly
Track how much oil to my car you’re adding monthly
Try Thicker Oil Temporarily
Switch to 10W-40 or 20W-50 as oil for cars that burn oil
Use Engine Seal Conditioners
Products like BlueDevil can slow leaks in engines that burn oil
Get a Compression Test
Identifies if piston rings cause car burning oil
But these are temporary fixes – they won’t solve worn internal components.
When Repairs Aren’t Worth It: Your Smartest Move
Fixing motor burning oil issues often costs more than the car’s value:
- Valve seal replacement: $500+
- Piston ring job: $3,000+
- Engine rebuild: $5,000+
Ask yourself:
- Is my car over 10 years old?
- Are repair quotes higher than its value?
- Do I have other looming issues (transmission, suspension)?
If you answered yes, selling your vehicle burning oil is financially smarter than pouring money into dying engines that burn oil.
