Hi All
I'm new hear so Hi from me.
I'm thinking about getting another Astra, had 2 previously a 2003 and 2010ish I think it was. Great little cars.

If I can't get hold or afford of a current shape Holden wagon I might go for the previous Opel Astra wagon. My question is;
The Holden Astra 1.4T runs on normal unleaded. The Opel needs Premium.
Can the Opel Astra be tweeked to run on Normal unleaded? Is it done by a Computer update or similar?
Unleaded is just way over priced here in Tasmania.
Thanks
Jiro
