S3 engine oil, transmission oil, haldex oil, rear dif oil and front dif oil?
hi guys, i've had a look across the internet but there seems to many different opinions and statements that i do not trust
i'm about to do a full service on my s3, so can you please advise on the following oils?
engine oil - Castrol Edge Fully Synthetic 5W30 Engine Oil? is this ok?
transmission oil - i'm a little confused here, i understand it's 75w90 but some people are saying not to use g5 and to use g4, what do you use, any good brands??
haldex oil - easy, buy direct from audi
rear diff - same as transmission oil?
front dif (if there is one?) - same as transmission oil?
