Got my hands on a litre of Shell Helix Ultra Extra Diesel 5w-30, and am itching to top up the engine with it but the bloody car doesn't use a drop between oil changes (11k or 1 year). Free oil and it's of no use...
So figured it would be an opportunity to ask about the Pennzoil/Shell similarities and differences. Is Shell also using GTL basestock? (I'm in Europe, Pennzoil isn't available locally anymore).
which pennzoil oils correspond to which shell oils?
Maybe in the next ten years the car starts using oil and I'll be able to top up with this.
