Opel engine in the Astra, potentially sitting on the lot for 2 years. 200 miles on it now means it got driven a few times and fresh gas was added. The oil condition itself is not really a concern, other than a point of curiousity. The filler cap says 5w-30, and I assume there is a Euro 5w-30 in there. Any idea who holds the Opel oil contract? If I thought it was plain dino oil in there, I'd change it out. Anyone have any thoughts on that? Since draining the gas tank is not an option, I plan on adding some FI cleaner to the existing gas, driving it home, refilling with fresh gas plus more FI cleaner. It's a detuned 10.5:1 compression ratio engine, but calls for 87 which I don't think they even sell in Europe. I assume there will be a benefit of premium gas going forward.
