Synth Oil Ques,

[Dave]

Hello, my name is Dave. My question goes as if the Synth oil with specially a visc of 5/20 tend to dissipate over a 7-8k miles. I have not notice any leaks at all. Can somebody shed some light on my findings, with a Scion XB 09.

That amount of oil use is normal.

Your oil consumption is a little high for Toyota engine, but oil you’re using may have a high Noack volatility (i.e., evaporation). You might want to try a different oil:

An oil analysis could also give you some guidance on what’s going on inside your motor.

Swingwing, thanks for you guys replies. Just recently read at the mannual that vehicle can consume a quart per each thousand miles, ration 1/1000. I had a little over 8k after last oil change and had -2.5 quarts. I will follow your advice regarding amsoil,

Recommend you check oil level more frequently and keep it topped up. Sump capacity for your engine is only 4.5 quarts, so running it low on oil is very hard on the engine. Are you using the recommended 0W-20 viscosity?
