Owner reviews for engine oil

Liqui Moly Molygen 5w40. Not cheap but I swear by it, made the engine quieter too

Just another clean option to compete with Valvoline.

Using Amsoil. Nung pinalitan ko valve gasket ng 2008 Vios ko walang sludge. Gold ang loob.

On chilly winter mornings (SF Bay Area) the car did not like reverse or first gears. Subsequently switched to Red Line engine oil. More power, better mileage.

Reduced oil consumption in my 2015 Volvo V60 with 143,000 miles

It has helped the valve tick in my 150k mile Yaris

I use Liquimoly Molygen (5W-40) and I’m very content.

I started using this on my high mileage Rav4 has definitely made the valve train noise quieter on the 2AR-Fe, I could swear the chain rattle that plagues these seems to have quieted down.

MOBIL 1 every 5k miles. Not the worst or the best oill

I know I was using penzoil back when I had a 90 325i, locked my engine up solid, mechanic said it had too much paraffin so yeah it matters personally I only use Mobil 1 synthetics
