Usually penzoil or quaker state.

 

I've read some of the 1.8t's problems are due to placement of the oil lines for the turbo. I wouldn't use anything but synth in a 1.8t, but honestly, the crap that castrol is the only one to use is just plain ignorant. Castrol PAYS VW/Audi for their endorsement, and Syntec (except for GC 0w30) is a group 3 oil... using dino base stocks.

Lets get back on topic here... he's got a 2.8, he doesn't NEED a synthetic per se, but I say keep using it.

 

Oil coming out clean is not a way to judge how well it lubricates, stands up to heat, etc. It coming out dirty could mean that it is actually cleaning your engine, picking up crap other oil left behind...

I use MOBIL 1 CLEAN 5000 synthetic blend.

i love it.

 

Castrol Synthetic 5-30 in winters and 10-40 in summertime....
Change it every 5k along with the Bosch big filter

 

how about pennzoil 5w-30 for winter and 10w-30 for summer. Of course penn syntethic. is that ok?
schucks is having a good deal right now. its about 6 bucks per case.

btw, just a reminder, i have a 96 a4 quattro.

thanks

 

I wouldn't have a problem running it with a shorter OCI, maybe 6k...

 

casterol 10w-40!!!
