Hello, I need to change the oil on my 1987 944 for the first time. I've been searching to find information about what type of oil is recomended and how much i need and cannot find any results. Also can anyone recomend what weight of oil would be recomended during summer seasons and winter times. I live in New Mexico and it is beginning to get colder. I can be in the 30's in the morning then quickly heat up to the mid 70's during the day.

Thank you very much for your help.

 

20w-50 castrol. 6.3 quarts.

If you want synthetic 15w-50 mobil 1.

 

Thanks, that helped a lot. I really appreciate your help.
