Your topics have been discussed ad nauseum. joe   Phillip Perkinson (Rover4x4) Senior Member Username: Rover4x4 Post Number: 435 Registered: 02-2003 Posted on Sunday, September 07, 2003 - 12:22 pm:    ALways BP 93 octane   June H.

From what I understand, I thought that the Discovery started requiring premium fuel sometime during the latter part of the Series I.   Sergei Rodionov (Uzbad) New Member Username: Uzbad Post Number: 22 Registered: 08-2003 Posted on Monday, September 08, 2003 - 12:22 am:    Actually it says 90-92 gasoline in my owners manual and mine is 3/94.   June H.

I always thought that premium started becoming a requirement along with the engine horsepower being boosted from 182 to 188 somewhere during the later part of Series I production. However, since your Disco is a very early example, then i'm probably wrong.
