I was talking with my stepdad the other day about oil in his 09 Jetta TDI. He lets the dealer do all the oil changes and apparently they use a 5w-30 at a 10K OCI. I was surprised to hear they used a 30 weight oil as I figured most diesel engines were spec'ed 40 weights.
Can anyone tell me what kind of oil they use at the dealers? Any VW service techs on here?
