Hi,
I got a Used Toyota RAV4 2005 model in February 2022 and drove it from Lagos to Akwa Ibom. The previous owner used Mobil oil for service. I noticed the oil level dropped after 2 weeks and I also noticed some leakages around the bottom plate. My mechanic fixed the leakage and I decided to change to Genuine Toyota Synthetic Oil 5w30. It's been about a month and the oil level this morning is a little above Low on the dipstick. What could be the reason for this excessive oil consumption? I hear metal noise whenever the car is ascending. My mechanic said the car is doing internal bleeding and we would need to change rings and grind the bearing responsible for the metal noise. Can this be fixed or do I manage the car back to Lagos and change the engine? I will appreciate expert advise. My WhatsApp number is 08135540756 Thanks.

I'm experiencing the same issue with a Corolla 2005 right now.

The obvious is that the rings are bad and needs to be replaced. But getting a good mechanic to fix it is the major problem.

Rings no.
New engine yes.

Only rings when there are no alternative to new engine.

Better avoid cars that required rings or engine replacement. It doesn't ever end or worth the stress.

Change back to Mobil xhp 20w50 and study oil consumption.

It isn't always good to change from 20w50 to full synthetic 5w30 on engines already used to heavy oil weight.

As for the gringrin noise, it could be oil starvation caused by the current weight you used.

Advice
1. Check exhaust for smoke when car rpm is at 3k with car stationery.

2. When current oil has drained check for tiny metal particles if present wahala yapa inside engine be that.

3. Check for sludge in engine and oil pan as full synthetics have bleach that will flush sludge to the wrong place causing oil starvation.

Also is your engine 1az or 2az?

You should properly inspect your PCV valve, that's if there is no smoke. Ringing or changing your engine should be last resort.
