I do about 4-5k miles a year. Last service was done about 9k miles ago but mechanic saying Oil level is below the dipstick. So wouldn't the engine Oil light come on?
That means I have used a full 5l can in 2 years even though I only drive 4-5k per year.
I have always used Toyota own 5w30 Oil even though on their website it states 0w20.
Now would changing to a fully synthetic Oil be an improvement?
