Is it okay to use 10w-40?

**BrucexL33** · 03-21-2010 02:43 PM

I recently bought a audi a4 b5 and had an oil change done using 10w-40 and i've notice most of you guys use 5w-40. Is that okay that i used 10w-40 instead? im pretty new to audi's so please be gentle xD. Thank You.

People use that weight oil on higher mileage vehicles, and others simply don't bother. I myself use 5w40 in the summer and 0w30 in the winter (128k on motor). The brand I use is also "not" on that Audi apporved list. But whatever you do, be sure to use full synthetic motor oil. Many use Group III, but you would want a Group IV motor oil.

I have a 1.8t with around 136,xxx miles and used Mobil 1 fully synthetic 10w-40 oil. that should be okay right?

You would need to wait for someone else to chimme in to answer that. But as far as I know, there shouldn't be an issue running that weight motor oil. You plan on running that same motor oil (weight) on your next change?

i believe so, unless something's wrong with that grade oil, i've driven the car about 200 miles since the oil change so ya, long way before i do another oil change.

I don't know how cold it gets in San Jose, but you may want to take that into consideration when choosing your oil for the winter season.
