15w -40w engine oil
 

Hi l have a 20 year old camry l had been having some higher then normal oil use. the old garage l went to always used 5w-30w synthetic engine oil but my new garage put in 15w-40w mineral engine oil and they said it better for an old car like mine, do you think they are correct? is the new 15w-40w mineral oil ok for my engine

What year of Camry and engine type as in 4 or 6 cylinder? Some Camry engines had oil usage problems due to a design problem and changing the oil weight did not change this.

Have used 15-40W in a older Camry engines but they didn't have a design problem. A different weight CAN greatly lower oil consumption while solving other problems as well.

thanks, its a 2003 camry and its a 4 cylinder, last couple of years its been using more oil then normal, hopefully this thicker oil will help, but l hope the thicker oil wont cause any problems as it wont flow as well as the 5w 30w l always used

Should be OK.

Your year was outside the affected range for the engine design problem.

Assume the mechanic checked the PCV system which can cause increased oil usage.
