My TDI is a 2006 VW New Beetle. I inherited it 2 1/2 yrs ago from my daughter. To my knowledge, only 5w30 and sometimes 5w40 have been used in it. Mileage is 139k. Yesterday, the foreign auto shop used 15w40 for routine oil change. I assumed they would be using 5w40. I didn't notice the change until I looked at the invoice now a day later. I live in East Texas, thus a hot weather climate w/o snow. I had hoped to stall off next oil change until closer to 10k miles (which will take me the rest of the year to reach). Question is: Need I be concerned about running on 15w40? Thank you in advance.
