How to Reduce High Oil Consumption in Toyota Aqua?

Hi everyone,

I own a Toyota Aqua 2014 model, 120,000 km, and I’ve recently observed that it’s using up more engine oil than expected. I’ve had to top it off frequently, and this wasn’t an issue before. There’s no visible smoke from the exhaust, and I haven’t noticed any leaks under the car.

I’m looking for advice on:

What could be causing this sudden increase in oil consumption?
Are there specific maintenance steps o r checks I should perform?
Would switching to a different grade o r type of engine oil help?
I’m hoping to avoid costly repairs, so any suggestions on diagnosing and resolving this issue would be really helpful.

Thanks in advance!

hi
Increased oil consumption in your Toyota Aqua could stem from several factors, especially given its mileage. While the absence of visible leaks o r smoke is a good sign, internal engine wear may still be a potential cause.

The primary reasons could include worn piston rings, valve seals, o r oil control rings, allowing oil to burn during combustion. Regular maintenance checks like inspecting the PCV Positive Crankcase Ventilation valve, which helps regulate engine pressure and can contribute to oil consumption if clogged, are worth considering.

Switching to a slightly thicker engine oil grade designed for high-mileage vehicles might reduce oil consumption. For example, if youre currently using 0W-20, you might try 5W-30, provided it’s within the manufacturers recommendations. However, consult your owner’s manual o r a trusted mechanic before making any changes.

Performing a compression test can help assess engine health and identify possible internal wear. Addressing the issue early can help avoid extensive repairs.
