hi guys i was wondering what you guys would recommend , i was wondering which oil to use, mobile 1 10w30 5w30? or what other ones? i have been using the 0w40 mobile 1 on 01 audi a4 1.8t 70k.. i was going to pick up an oil filter at the dealership

thanks

 

mobil1 0w40 is the mobil1 approved by audi. if you want other options just search, it has been more then covered.

 

so would you say that it is the best to just stick with the same? even summer time and all that?

thanks

 

Where do you live and do you have cold winters and hot summers? If you do you might want to run a 0w30 for winter and 0w40/5w40 for summer. You want to use the different weights to control oil temps, if the oil temps get too high you are running too thin of an oil and if they stay too low then you are running too thick of an oil.

Thinner oils will allow the motor to get better gas mileage. Mobil 1 is not 100% synthetic. If you want 100% you want to run an oil like Redline or Motul.

 

I run Mobile 1 0w40 too, but I'll probably have to change that when I move back to Maine in September. Max ambient temp range there is about 100F in the summer to about -30F in the winter.

Do you guys think it'd be ok to stick to one type of oil all year round with those temps?
